1.5 Version identification of EtherCAT devices

Designation

A Beckhoff EtherCAT device has a 14-digit designation, made up of

• family key
• type
• version
• revision
Example Family Type Version Revision
EL3314-0000-0016 EL terminal 3314 (4-channel thermocouple 0000 (basic type) 0016
(12 mm, non- terminal)
pluggable connection
level)
ES3602-0010-0017 ES terminal 3602 (2-channel voltage 0010 (high- 0017
(12 mm, pluggable measurement) precision version)
connection level)
CU2008-0000-0000 CU device 2008 (8-port fast ethernet switch) 0000 (basic type) 0000

Notes
• The elements mentioned above result in the technical designation. EL3314-0000-0016 is used in the
example below.
• EL3314-0000 is the order identifier, in the case of “-0000” usually abbreviated to EL3314. “-0016” is the
EtherCAT revision.
• The order identifier is made up of
- family key (EL, EP, CU, ES, KL, CX, etc.)
- type (3314)
- version (-0000)
• The revision -0016 shows the technical progress, such as the extension of features with regard to the
EtherCAT communication, and is managed by Beckhoff.
In principle, a device with a higher revision can replace a device with a lower revision, unless specified
otherwise, e.g. in the documentation.
Associated and synonymous with each revision there is usually a description (ESI, EtherCAT Slave

EL600x, EL602x Version: 4.6 9

Foreword

Information) in the form of an XML file, which is available for download from the Beckhoff web site.
From 2014/01 the revision is shown on the outside of the IP20 terminals, see Fig. “EL5021 EL terminal,
standard IP20 IO device with batch number and revision ID (since 2014/01)”.
• The type, version and revision are read as decimal numbers, even if they are technically saved in
hexadecimal.

Identification number

Beckhoff EtherCAT devices from the different lines have different kinds of identification numbers:

Production lot/batch number/serial number/date code/D number

The serial number for Beckhoff IO devices is usually the 8-digit number printed on the device or on a sticker.
The serial number indicates the configuration in delivery state and therefore refers to a whole production
batch, without distinguishing the individual modules of a batch.

Structure of the serial number: KK YY FF HH

KK - week of production (CW, calendar week)

YY - year of production
FF - firmware version
HH - hardware version

Example with
Ser. no.: 12063A02:    12 - production week 12 06 - production year 2006 3A - firmware version 3A 02 -
hardware version 02

Exceptions can occur in the IP67 area, where the following syntax can be used (see respective device
documentation):

Syntax: D ww yy x y z u

D - prefix designation
ww - calendar week
yy - year
x - firmware version of the bus PCB
y - hardware version of the bus PCB
z - firmware version of the I/O PCB
u - hardware version of the I/O PCB

Example: D.22081501 calendar week 22 of the year 2008 firmware version of bus PCB: 1 hardware version
of bus PCB: 5 firmware version of I/O PCB: 0 (no firmware necessary for this PCB) hardware version of I/O
PCB: 1

Unique serial number/ID, ID number

In addition, in some series each individual module has its own unique serial number.

Product overview

2 Product overview
Technology

The EL600x and EL602x serial interface terminals enable the connection of devices with an RS232 (or
RS485 / RS422) interface. In the case of the EL600x, the data is exchanged with the controller in full duplex
mode; in the case of the EL602x, half duplex mode is additionally possible. The terminal has one receive
buffer an one transmit buffer per channel, see technical data. Data transfer between the terminal and the
controller takes place via a handshake.

The factory setting of the terminals is:

• 9600 baud
• 8N1: 8 data bits, 1 stop bit, no parity
• in the EL600x the RTS/CTS control is active
• the EL602x operates in full duplex mode with deactivated point-to-point connection.

Basic principles

During transfer of several bytes of data, the data (x bytes or 8*x bits in total) are sent in individual telegrams
containing 7 or 8 bits, based on the coding specification (e.g. 7E2 or 8N1). A telegram consists of:
• Start bit
• Data bits (7 or 8, starting with the LSB [least significant bit])
• Optional: parity bit
◦ "E" EVEN: The parity bit is set by the sender such that the parity is even
◦ "O" ODD: The parity bit is set by the sender such that the parity is odd
◦ "N" NOT: no parity bit
◦ "M" MARK: The parity bit is set to 1 by the sender
◦ "S" SPACE: The parity bit is set to 0 by the sender
• Stop bit (1 or 2)

Accordingly, the coding specification 8N1 means: 8 data bits, no parity bit, 1 stop bit.

If 7-bit coding is selected, of each data byte that is transferred from the PLC to the terminal via the cyclic
process data, only the lower 7 bits are sent. In other words, if 10 bytes of data (consisting of 8 bits) are sent
to the EL60xx, 10 telegrams of 7 bits each are sent.

If 9-bit coding is selected, the 16-bit process data interface must be used. The terminal then expects the 9
useful bits in the lower 9 bits of the 16-bit word.

Frequency

The frequency of the data transfer must be known in the sender and receiver and match within a few
percent, in order to ensure that the receiver can correctly detect any changes in level on the line.

Handshake

An additional handshake between the sender and the receiver can be used so that the receiver can indicate
that it is ready to receive. The EL60xx supports two types of handshake:
• via special RTS/CTS data cables
◦ This features must be activated in the CoE.
◦ Only possible with EL6001/EL6002.
• via special data telegrams
◦ This features must be activated in the CoE.

 Product overview

Level interfaces

The EL6001/6002 devices operate at an RS232 level with reference to GND, the EL6021/6022 devices with
a differential RS485/422 level.

Fig. 9: Level interfaces RS232, RS485/422

Termination and topology

The serial RS422 and RS485 communication technologies operate with voltage levels on a 2-wire line.
Reflections at high-resistance line ends can lead to signal distortion. For this reason termination resistors are
required at the receiver. For RS422/485 these are 120 Ω resistors, which together with the line resistance
result in a voltage drop over the transmission link.

Permitted cable length

The line resistance together with the termination resistor results in an overall voltage drop over the
transmission link. An unacceptably high number of termination resistors would result in excessive
attenuation of the signal.
The system design should ensure that the voltage does not drop below 200 mV at the receiver (see
Fig. ), which is the minimum voltage required.

In RS422 mode each line must be terminated with 120 Ω at the receiver.

Fig. 10: RS422 termination

In RS485 mode with several devices, termination resistors are only used at the two end devices.

EL600x, EL602x Version: 4.6 15

Product overview

Fig. 11: RS485 termination

The background is the different design of RS422/EIA-422 and RS485/EIA-485:

• RS422: 1 Rx → Tx n (maximum 10 receivers)
• RS485: n Rx → Tx m (maximum 32/128 devices, depending on the resulting bus loading)

Components for RS485 usually have a higher input impedance, resulting in lower bus load.

Termination with EL602x and BIAS resistors

The EL602x devices do not have integrated termination resistors, in order to enable operation in
bus mode. Any termination that may be required must be connected outside the terminal.
The EL602x devices feature integrated bias resistors < 1 kOhm, which bring the bus lines to defined
levels, even if the line is disconnected.
If several EL602x devices are connected in a bus, the parallel bias resistors may hamper the data
communication. In this case the EL6021-0021, which has significantly higher bias resistors, should
be used as an intermediate device.

Topology

The termination and the bias resistors generate a load on the bus. However, they are essential for
unambiguous bus levels and therefore have to be positioned with diligence. Ideally the RS422/485 bus
should be configured as a daisy chain or a simple chain, see Fig. [} 17] The following topologies may be
problematic:
• Star topologies: each end point should ideally be terminated, but this can lead to excessive bus loading
and ambiguous signal levels. Other potential issues are reflections and runtime variations.
• Intermeshed topologies: no clear end points, which means reflections and circulating currents are
possible.

Shielding/shield

NOTE
Do not use functional earth for discharge of residual currents or potential differences!
The EL60xx units offer a shielded connection for discharging EMC interference via the cable shield (FE,
functional earth). The shield must not be misused for discharging residual currents or potential differences.

2.1.1 Introduction

Serial Interface Terminal (RS232C/RS422/RS485), 1 channel

The EL6001 and EL6021 serial interfaces enable the connection of devices with RS-232 or RS422/RS485
interface. The EL6001 operates in conformity with the CCITT V.28/DIN 66 259-1 standards.
The device connected to the EL6001 EtherCAT Terminal communicates with the automation device via the
coupler. The active communication channel operates independently of the higher-level bus system in full
duplex mode or selectable half duplex mode (EL6021) at up to 115.2 kbaud.
The RS232 interface guarantees high immunity to interference through electrically isolated signals, which is
additionally guaranteed for the EL6021 through differential signal transmission.

In conjunction with the TwinCAT Virtual Serial COM Driver (see TwinCAT Supplements – Communication)
the EL6001/EL6021 can be used as a normal Windows COM interface.

2.2 EL6002, EL6022

2.2.1 Introduction

Serial Interface Terminal (RS232C/RS422/RS485), 2 channel

The EL6002 and EL6022 serial interfaces enable the connection of devices with two RS232 or two RS422/
RS485 interfaces each with one D-Sub connector (9 pin). The interfaces are electrically isolated from each
other and from the EtherCAT.
The devices connected to the EL6002/EL6022 EtherCAT Terminals communicate with the automation
device via the Coupler. The active communication channel operates independently of the higher-level
EtherCAT system in full duplex mode with 300 baud up to 115.2 kbaud.
The RS232/RS422/RS485 interfaces guarantee high interference immunity through electrically isolated
signals. The EL6022 can provide 2 x 5 V/20 mA from the E-bus supply (electrically isolated, short-circuit-
proof) as supply for external devices.

In conjunction with the TwinCAT Virtual Serial COM Driver, the EL60xx can be used as a normal Windows
COM interface.

3.1 EtherCAT basics

Please refer to the chapter EtherCAT System Documentation for the EtherCAT fieldbus basics.

3.2 EtherCAT cabling – wire-bound

The cable length between two EtherCAT devices must not exceed 100 m. This results from the FastEthernet
technology, which, above all for reasons of signal attenuation over the length of the cable, allows a maximum
link length of 5 + 90 + 5 m if cables with appropriate properties are used. See also the Design
recommendations for the infrastructure for EtherCAT/Ethernet.

Cables and connectors

For connecting EtherCAT devices only Ethernet connections (cables + plugs) that meet the requirements of
at least category 5 (CAt5) according to EN 50173 or ISO/IEC 11801 should be used. EtherCAT uses 4 wires
for signal transfer.

EtherCAT uses RJ45 plug connectors, for example. The pin assignment is compatible with the Ethernet
standard (ISO/IEC 8802-3).

Pin Color of conductor Signal Description

1 yellow TD + Transmission Data +
2 orange TD - Transmission Data -
3 white RD + Receiver Data +
6 blue RD - Receiver Data -

Due to automatic cable detection (auto-crossing) symmetric (1:1) or cross-over cables can be used between
EtherCAT devices from Beckhoff.

Recommended cables
Suitable cables for the connection of EtherCAT devices can be found on the Beckhoff website!

E-Bus supply

A bus coupler can supply the EL terminals added to it with the E-bus system voltage of 5 V; a coupler is
thereby loadable up to 2 A as a rule (see details in respective device documentation).
Information on how much current each EL terminal requires from the E-bus supply is available online and in
the catalogue. If the added terminals require more current than the coupler can supply, then power feed
terminals (e.g. EL9410) must be inserted at appropriate places in the terminal strand.

The pre-calculated theoretical maximum E-Bus current is displayed in the TwinCAT System Manager. A
shortfall is marked by a negative total amount and an exclamation mark; a power feed terminal is to be
placed before such a position.

NOTE
Malfunction possible!
The same ground potential must be used for the E-Bus supply of all EtherCAT terminals in a terminal block!

3.3 General notes for setting the watchdog

ELxxxx terminals are equipped with a safety feature (watchdog) that switches off the outputs after a
specifiable time e.g. in the event of an interruption of the process data traffic, depending on the device and
settings, e.g. in OFF state.

The EtherCAT slave controller (ESC) in the EL2xxx terminals features 2 watchdogs:
• SM watchdog (default: 100 ms)
• PDI watchdog (default: 100 ms)

SM watchdog (SyncManager Watchdog)

The SyncManager watchdog is reset after each successful EtherCAT process data communication with the
terminal. If no EtherCAT process data communication takes place with the terminal for longer than the set
and activated SM watchdog time, e.g. in the event of a line interruption, the watchdog is triggered and the
outputs are set to FALSE. The OP state of the terminal is unaffected. The watchdog is only reset after a
successful EtherCAT process data access. Set the monitoring time as described below.

The SyncManager watchdog monitors correct and timely process data communication with the ESC from the
EtherCAT side.

PDI watchdog (Process Data Watchdog)

If no PDI communication with the EtherCAT slave controller (ESC) takes place for longer than the set and
activated PDI watchdog time, this watchdog is triggered.
PDI (Process Data Interface) is the internal interface between the ESC and local processors in the EtherCAT
slave, for example. The PDI watchdog can be used to monitor this communication for failure.

The PDI watchdog monitors correct and timely process data communication with the ESC from the
application side.

The settings of the SM- and PDI-watchdog must be done for each slave separately in the TwinCAT System
Manager.

EL600x, EL602x Version: 4.6 23

Basics communication

Fig. 14: EtherCAT tab -> Advanced Settings -> Behavior -> Watchdog

Notes:
• the multiplier is valid for both watchdogs.
• each watchdog has its own timer setting, the outcome of this in summary with the multiplier is a
resulting time.
• Important: the multiplier/timer setting is only loaded into the slave at the start up, if the checkbox is
activated.
If the checkbox is not activated, nothing is downloaded and the ESC settings remain unchanged.

Multiplier

Multiplier

Both watchdogs receive their pulses from the local terminal cycle, divided by the watchdog multiplier:

1/25 MHz * (watchdog multiplier + 2) = 100 µs (for default setting of 2498 for the multiplier)

The standard setting of 1000 for the SM watchdog corresponds to a release time of 100 ms.

The value in multiplier + 2 corresponds to the number of basic 40 ns ticks representing a watchdog tick.
The multiplier can be modified in order to adjust the watchdog time over a larger range.

24 Version: 4.6 EL600x, EL602x

 Basics communication

Example "Set SM watchdog"

This checkbox enables manual setting of the watchdog times. If the outputs are set and the EtherCAT
communication is interrupted, the SM watchdog is triggered after the set time and the outputs are erased.
This setting can be used for adapting a terminal to a slower EtherCAT master or long cycle times. The
default SM watchdog setting is 100 ms. The setting range is 0..65535. Together with a multiplier with a range
of 1..65535 this covers a watchdog period between 0..~170 seconds.

Calculation

Multiplier = 2498 → watchdog base time = 1 / 25 MHz * (2498 + 2) = 0.0001 seconds = 100 µs

SM watchdog = 10000 → 10000 * 100 µs = 1 second watchdog monitoring time

CAUTION
Undefined state possible!
The function for switching off of the SM watchdog via SM watchdog = 0 is only implemented in terminals
from version -0016. In previous versions this operating mode should not be used.

CAUTION
Damage of devices and undefined state possible!
If the SM watchdog is activated and a value of 0 is entered the watchdog switches off completely. This is
the deactivation of the watchdog! Set outputs are NOT set in a safe state, if the communication is inter-
rupted.

3.4 EtherCAT State Machine

The state of the EtherCAT slave is controlled via the EtherCAT State Machine (ESM). Depending upon the
state, different functions are accessible or executable in the EtherCAT slave. Specific commands must be
sent by the EtherCAT master to the device in each state, particularly during the bootup of the slave.

A distinction is made between the following states:

• Init
• Pre-Operational
• Safe-Operational and
• Operational
• Boot

The regular state of each EtherCAT slave after bootup is the OP state.

EL600x, EL602x Version: 4.6 25

Basics communication

Fig. 15: States of the EtherCAT State Machine

Init

After switch-on the EtherCAT slave in the Init state. No mailbox or process data communication is possible.
The EtherCAT master initializes sync manager channels 0 and 1 for mailbox communication.

Pre-Operational (Pre-Op)

During the transition between Init and Pre-Op the EtherCAT slave checks whether the mailbox was initialized
correctly.

In Pre-Op state mailbox communication is possible, but not process data communication. The EtherCAT
master initializes the sync manager channels for process data (from sync manager channel 2), the FMMU
channels and, if the slave supports configurable mapping, PDO mapping or the sync manager PDO
assignment. In this state the settings for the process data transfer and perhaps terminal-specific parameters
that may differ from the default settings are also transferred.

Safe-Operational (Safe-Op)

During transition between Pre-Op and Safe-Op the EtherCAT slave checks whether the sync manager
channels for process data communication and, if required, the distributed clocks settings are correct. Before
it acknowledges the change of state, the EtherCAT slave copies current input data into the associated DP-
RAM areas of the EtherCAT slave controller (ECSC).

In Safe-Op state mailbox and process data communication is possible, although the slave keeps its outputs
in a safe state, while the input data are updated cyclically.

Outputs in SAFEOP state

The default set watchdog [} 23] monitoring sets the outputs of the module in a safe state - depend-
ing on the settings in SAFEOP and OP - e.g. in OFF state. If this is prevented by deactivation of the
watchdog monitoring in the module, the outputs can be switched or set also in the SAFEOP state.

Operational (Op)

Before the EtherCAT master switches the EtherCAT slave from Safe-Op to Op it must transfer valid output
data.

In the Op state the slave copies the output data of the masters to its outputs. Process data and mailbox
communication is possible.

26 Version: 4.6 EL600x, EL602x

 Basics communication

Boot

In the Boot state the slave firmware can be updated. The Boot state can only be reached via the Init state.

In the Boot state mailbox communication via the file access over EtherCAT (FoE) protocol is possible, but no
other mailbox communication and no process data communication.

3.5 CoE Interface

General description

The CoE interface (CANopen over EtherCAT) is used for parameter management of EtherCAT devices.
EtherCAT slaves or the EtherCAT master manage fixed (read only) or variable parameters which they
require for operation, diagnostics or commissioning.

CoE parameters are arranged in a table hierarchy. In principle, the user has read access via the fieldbus.
The EtherCAT master (TwinCAT System Manager) can access the local CoE lists of the slaves via
EtherCAT in read or write mode, depending on the attributes.

Different CoE parameter types are possible, including string (text), integer numbers, Boolean values or larger
byte fields. They can be used to describe a wide range of features. Examples of such parameters include
manufacturer ID, serial number, process data settings, device name, calibration values for analog
measurement or passwords.

The order is specified in 2 levels via hexadecimal numbering: (main)index, followed by subindex. The value
ranges are
• Index: 0x0000 …0xFFFF (0...65535dez)
• SubIndex: 0x00…0xFF (0...255dez)

A parameter localized in this way is normally written as 0x8010:07, with preceding "x" to identify the
hexadecimal numerical range and a colon between index and subindex.

The relevant ranges for EtherCAT fieldbus users are:

• 0x1000: This is where fixed identity information for the device is stored, including name, manufacturer,
serial number etc., plus information about the current and available process data configurations.
• 0x8000: This is where the operational and functional parameters for all channels are stored, such as
filter settings or output frequency.

Other important ranges are:

• 0x4000: In some EtherCAT devices the channel parameters are stored here (as an alternative to the
0x8000 range).
• 0x6000: Input PDOs ("input" from the perspective of the EtherCAT master)
• 0x7000: Output PDOs ("output" from the perspective of the EtherCAT master)

Availability
Not every EtherCAT device must have a CoE list. Simple I/O modules without dedicated processor
usually have no variable parameters and therefore no CoE list.

If a device has a CoE list, it is shown in the TwinCAT System Manager as a separate tab with a listing of the
elements:

EL600x, EL602x Version: 4.6 27

Basics communication

Fig. 16: "CoE Online " tab

The figure above shows the CoE objects available in device "EL2502", ranging from 0x1000 to 0x1600. The
subindices for 0x1018 are expanded.

Data management and function "NoCoeStorage"

Some parameters, particularly the setting parameters of the slave, are configurable and writeable. This can
be done in write or read mode
• via the System Manager (Fig. "CoE Online " tab) by clicking
This is useful for commissioning of the system/slaves. Click on the row of the index to be
parameterised and enter a value in the "SetValue" dialog.
• from the control system/PLC via ADS, e.g. through blocks from the TcEtherCAT.lib library
This is recommended for modifications while the system is running or if no System Manager or
operating staff are available.

Data management
If slave CoE parameters are modified online, Beckhoff devices store any changes in a fail-safe
manner in the EEPROM, i.e. the modified CoE parameters are still available after a restart.
The situation may be different with other manufacturers.

An EEPROM is subject to a limited lifetime with respect to write operations. From typically 100,000
write operations onwards it can no longer be guaranteed that new (changed) data are reliably saved
or are still readable. This is irrelevant for normal commissioning. However, if CoE parameters are
continuously changed via ADS at machine runtime, it is quite possible for the lifetime limit to be
reached. Support for the NoCoeStorage function, which suppresses the saving of changed CoE val-
ues, depends on the firmware version.
Please refer to the technical data in this documentation as to whether this applies to the respective
device.
• If the function is supported: the function is activated by entering the code word 0x12345678 once
in CoE 0xF008 and remains active as long as the code word is not changed. After switching the
device on it is then inactive. Changed CoE values are not saved in the EEPROM and can thus
be changed any number of times.
• Function is not supported: continuous changing of CoE values is not permissible in view of the
lifetime limit.

28 Version: 4.6 EL600x, EL602x

 Basics communication

Startup list
Changes in the local CoE list of the terminal are lost if the terminal is replaced. If a terminal is re-
placed with a new Beckhoff terminal, it will have the default settings. It is therefore advisable to link
all changes in the CoE list of an EtherCAT slave with the Startup list of the slave, which is pro-
cessed whenever the EtherCAT fieldbus is started. In this way a replacement EtherCAT slave can
automatically be parameterized with the specifications of the user.
If EtherCAT slaves are used which are unable to store local CoE values permanently, the Startup
list must be used.

Recommended approach for manual modification of CoE parameters

• Make the required change in the System Manager
The values are stored locally in the EtherCAT slave
• If the value is to be stored permanently, enter it in the Startup list.
The order of the Startup entries is usually irrelevant.

Fig. 17: Startup list in the TwinCAT System Manager

The Startup list may already contain values that were configured by the System Manager based on the ESI
specifications. Additional application-specific entries can be created.

Online/offline list

While working with the TwinCAT System Manager, a distinction has to be made whether the EtherCAT
device is "available", i.e. switched on and linked via EtherCAT and therefore online, or whether a
configuration is created offline without connected slaves.

In both cases a CoE list as shown in Fig. “’CoE online’ tab” is displayed. The connectivity is shown as offline/
online.
• If the slave is offline
◦ The offline list from the ESI file is displayed. In this case modifications are not meaningful or
possible.
◦ The configured status is shown under Identity.
◦ No firmware or hardware version is displayed, since these are features of the physical device.
◦ Offline is shown in red.

◦ Online is shown in green.

Fig. 19: Online list

30 Version: 4.6 EL600x, EL602x

 Basics communication

Channel-based order

The CoE list is available in EtherCAT devices that usually feature several functionally equivalent channels.
For example, a 4-channel analog 0..10 V input terminal also has 4 logical channels and therefore 4 identical
sets of parameter data for the channels. In order to avoid having to list each channel in the documentation,
the placeholder "n" tends to be used for the individual channel numbers.

In the CoE system 16 indices, each with 255 subindices, are generally sufficient for representing all channel
parameters. The channel-based order is therefore arranged in 16dec/10hex steps. The parameter range
0x8000 exemplifies this:
• Channel 0: parameter range 0x8000:00 ... 0x800F:255
• Channel 1: parameter range 0x8010:00 ... 0x801F:255
• Channel 2: parameter range 0x8020:00 ... 0x802F:255
• ...

This is generally written as 0x80n0.

Detailed information on the CoE interface can be found in the EtherCAT system documentation on the
Beckhoff website.

3.6 Distributed Clock

The distributed clock represents a local clock in the EtherCAT slave controller (ESC) with the following
characteristics:
• Unit 1 ns
• Zero point 1.1.2000 00:00
• Size 64 bit (sufficient for the next 584 years; however, some EtherCAT slaves only offer 32-bit support,
i.e. the variable overflows after approx. 4.2 seconds)
• The EtherCAT master automatically synchronizes the local clock with the master clock in the EtherCAT
bus with a precision of < 100 ns.

Mounting and Wiring

Assembly

Fig. 21: Attaching on mounting rail

The bus coupler and bus terminals are attached to commercially available 35 mm mounting rails (DIN rails
according to EN 60715) by applying slight pressure:

1. First attach the fieldbus coupler to the mounting rail.

2. The bus terminals are now attached on the right-hand side of the fieldbus coupler. Join the compo-
nents with tongue and groove and push the terminals against the mounting rail, until the lock clicks
onto the mounting rail.
If the terminals are clipped onto the mounting rail first and then pushed together without tongue and
groove, the connection will not be operational! When correctly assembled, no significant gap should
be visible between the housings.

Fixing of mounting rails

The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At
the installation, the locking mechanism of the components must not come into conflict with the fixing
bolts of the mounting rail. To mount the mounting rails with a height of 7.5 mm under the terminals
and couplers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).

34 Version: 4.6 EL600x, EL602x

 Mounting and Wiring

Disassembly

Fig. 22: Disassembling of terminal

Each terminal is secured by a lock on the mounting rail, which must be released for disassembly:

1. Pull the terminal by its orange-colored lugs approximately 1 cm away from the mounting rail. In doing
so for this terminal the mounting rail lock is released automatically and you can pull the terminal out of
the bus terminal block easily without excessive force.
2. Grasp the released terminal with thumb and index finger simultaneous at the upper and lower grooved
housing surfaces and pull the terminal out of the bus terminal block.

Connections within a bus terminal block

The electric connections between the Bus Coupler and the Bus Terminals are automatically realized by
joining the components:
• The six spring contacts of the K-Bus/E-Bus deal with the transfer of the data and the supply of the Bus
Terminal electronics.
• The power contacts deal with the supply for the field electronics and thus represent a supply rail within
the bus terminal block. The power contacts are supplied via terminals on the Bus Coupler (up to 24 V)
or for higher voltages via power feed terminals.

Power Contacts
During the design of a bus terminal block, the pin assignment of the individual Bus Terminals must
be taken account of, since some types (e.g. analog Bus Terminals or digital 4-channel Bus Termi-
nals) do not or not fully loop through the power contacts. Power Feed Terminals (KL91xx, KL92xx
or EL91xx, EL92xx) interrupt the power contacts and thus represent the start of a new supply rail.

PE power contact

The power contact labeled PE can be used as a protective earth. For safety reasons this contact mates first
when plugging together, and can ground short-circuit currents of up to 125 A.

EL600x, EL602x Version: 4.6 35

Mounting and Wiring

Fig. 23: Power contact on left side

NOTE
Possible damage of the device
Note that, for reasons of electromagnetic compatibility, the PE contacts are capacitatively coupled to the
mounting rail. This may lead to incorrect results during insulation testing or to damage on the terminal (e.g.
disruptive discharge to the PE line during insulation testing of a consumer with a nominal voltage of 230 V).
For insulation testing, disconnect the PE supply line at the Bus Coupler or the Power Feed Terminal! In or-
der to decouple further feed points for testing, these Power Feed Terminals can be released and pulled at
least 10 mm from the group of terminals.

WARNING
Risk of electric shock!
The PE power contact must not be used for other potentials!

Overview

The Bus Terminal system offers different connection options for optimum adaptation to the respective
application:
• The terminals of ELxxxx and KLxxxx series with standard wiring include electronics and connection
level in a single enclosure.
• The terminals of ESxxxx and KSxxxx series feature a pluggable connection level and enable steady
wiring while replacing.
• The High Density Terminals (HD Terminals) include electronics and connection level in a single
enclosure and have advanced packaging density.

 Mounting and Wiring

Standard wiring (ELxxxx / KLxxxx)

Fig. 24: Standard wiring

The terminals of ELxxxx and KLxxxx series have been tried and tested for years.
They feature integrated screwless spring force technology for fast and simple assembly.

Pluggable wiring (ESxxxx / KSxxxx)

Fig. 25: Pluggable wiring

The terminals of ESxxxx and KSxxxx series feature a pluggable connection level.
The assembly and wiring procedure is the same as for the ELxxxx and KLxxxx series.
The pluggable connection level enables the complete wiring to be removed as a plug connector from the top
of the housing for servicing.
The lower section can be removed from the terminal block by pulling the unlocking tab.
Insert the new component and plug in the connector with the wiring. This reduces the installation time and
eliminates the risk of wires being mixed up.

The familiar dimensions of the terminal only had to be changed slightly. The new connector adds about 3
mm. The maximum height of the terminal remains unchanged.

A tab for strain relief of the cable simplifies assembly in many applications and prevents tangling of individual
connection wires when the connector is removed.

Conductor cross sections between 0.08 mm2 and 2.5 mm2 can continue to be used with the proven spring
force technology.

The overview and nomenclature of the product names for ESxxxx and KSxxxx series has been retained as
known from ELxxxx and KLxxxx series.

High Density Terminals (HD Terminals)

Fig. 26: High Density Terminals

The Bus Terminals from these series with 16 terminal points are distinguished by a particularly compact
design, as the packaging density is twice as large as that of the standard 12 mm Bus Terminals. Massive
conductors and conductors with a wire end sleeve can be inserted directly into the spring loaded terminal
point without tools.

4.2.3 Positioning of passive Terminals

Hint for positioning of passive terminals in the bus terminal block
EtherCAT Terminals (ELxxxx / ESxxxx), which do not take an active part in data transfer within the
bus terminal block are so called passive terminals. The passive terminals have no current consump-
tion out of the E-Bus.
To ensure an optimal data transfer, you must not directly string together more than 2 passive termi-
nals!

Mounting and Wiring

Fixing of mounting rails

The locking mechanism of the terminals and couplers extends to the profile of the mounting rail. At
the installation, the locking mechanism of the components must not come into conflict with the fixing
bolts of the mounting rail. To mount the recommended mounting rails under the terminals and cou-
plers, you should use flat mounting connections (e.g. countersunk screws or blind rivets).

WARNING
Risk of electric shock and damage of device!
Bring the bus terminal system into a safe, powered down state before starting installation, disassembly or
wiring of the Bus Terminals!

Mounting
• Fit the mounting rail to the planned assembly location.

and press (1) the terminal module against the mounting rail until it latches in place on the mounting
rail (2).
• Attach the cables.

Demounting
• Remove all the cables.
• Lever the unlatching hook back with thumb and forefinger (3). An internal mechanism pulls the two
latching lugs (3a) from the top hat rail back into the terminal module.

4.5 Installation instructions for enhanced mechanical load

capacity
WARNING
Risk of injury through electric shock and damage to the device!
Bring the Bus Terminal system into a safe, de-energized state before starting mounting, disassembly or
wiring of the Bus Terminals!

Additional checks

The terminals have undergone the following additional tests:

Verification Explanation
Vibration 10 frequency runs in 3 axes
6 Hz < f < 60 Hz displacement 0.35 mm, constant amplitude
60.1 Hz < f < 500 Hz acceleration 5 g, constant amplitude
Shocks 1000 shocks in each direction, in 3 axes
25 g, 6 ms

Additional installation instructions

For terminals with enhanced mechanical load capacity, the following additional installation instructions apply:
• The enhanced mechanical load capacity is valid for all permissible installation positions
• Use a mounting rail according to EN 60715 TH35-15
• Fix the terminal segment on both sides of the mounting rail with a mechanical fixture, e.g. an earth
terminal or reinforced end clamp
• The maximum total extension of the terminal segment (without coupler) is:
64 terminals (12 mm mounting with) or 32 terminals (24 mm mounting with)
• Avoid deformation, twisting, crushing and bending of the mounting rail during edging and installation of
the rail
• The mounting points of the mounting rail must be set at 5 cm intervals
• Use countersunk head screws to fasten the mounting rail
• The free length between the strain relief and the wire connection should be kept as short as possible. A
distance of approx. 10 cm should be maintained to the cable duct.

4.6 Installation positions

NOTE
Constraints regarding installation position and operating temperature range
Please refer to the technical data for a terminal to ascertain whether any restrictions regarding the installa-
tion position and/or the operating temperature range have been specified. When installing high power dissi-
pation terminals ensure that an adequate spacing is maintained between other components above and be-
low the terminal in order to guarantee adequate ventilation!

Optimum installation position (standard)

The optimum installation position requires the mounting rail to be installed horizontally and the connection
surfaces of the EL/KL terminals to face forward (see Fig. “Recommended distances for standard installation
position”). The terminals are ventilated from below, which enables optimum cooling of the electronics through
convection. "From below" is relative to the acceleration of gravity.

Fig. 39: Recommended distances for standard installation position

Compliance with the distances shown in Fig. “Recommended distances for standard installation position” is
recommended.

Other installation positions

All other installation positions are characterized by different spatial arrangement of the mounting rail - see
Fig “Other installation positions”.

The minimum distances to ambient specified above also apply to these installation positions.

5.1.1 TwinCAT 2

Startup

TwinCAT basically uses two user interfaces: the TwinCAT System Manager for communication with the
electromechanical components and TwinCAT PLC Control for the development and compilation of a
controller. The starting point is the TwinCAT System Manager.

After successful installation of the TwinCAT system on the PC to be used for development, the TwinCAT 2
System Manager displays the following user interface after startup:

Fig. 43: Initial TwinCAT 2 user interface

58 Version: 4.6 EL600x, EL602x

 Commissioning

Generally, TwinCAT can be used in local or remote mode. Once the TwinCAT system including the user
interface (standard) is installed on the respective PLC, TwinCAT can be used in local mode and thereby the
next step is "Insert Device [} 60]".

If the intention is to address the TwinCAT runtime environment installed on a PLC as development
environment remotely from another system, the target system must be made known first. In the menu under

"Actions" → "Choose Target System...", via the symbol " " or the "F8" key, open the following window:

Fig. 44: Selection of the target system

Use "Search (Ethernet)..." to enter the target system. Thus a next dialog opens to either:
• enter the known computer name after "Enter Host Name / IP:" (as shown in red)
• perform a "Broadcast Search" (if the exact computer name is not known)
• enter the known computer IP or AmsNetID.

Fig. 45: Specify the PLC for access by the TwinCAT System Manager: selection of the target system

Once the target system has been entered, it is available for selection as follows (a password may have to be
entered):

After confirmation with "OK" the target system can be accessed via the System Manager.

Adding devices

In the configuration tree of the TwinCAT 2 System Manager user interface on the left, select "I/O Devices”
and then right-click to open a context menu and select "Scan Devices…", or start the action in the menu bar

via . The TwinCAT System Manager may first have to be set to "Config mode" via or via menu
“Actions" → "Set/Reset TwinCAT to Config Mode…" (Shift + F4).

Fig. 46: Select "Scan Devices..."

Confirm the warning message, which follows, and select "EtherCAT" in the dialog:

Fig. 47: Automatic detection of I/O devices: selection the devices to be integrated

Confirm the message "Find new boxes", in order to determine the terminals connected to the devices. "Free
Run" enables manipulation of input and output values in "Config mode" and should also be acknowledged.

then determine the connected elements such as boxes, terminals, etc.). A scan can also be initiated by
selecting "Device ..." from the context menu, which then reads the elements present in the configuration
below:

This functionality is useful if the actual configuration is modified at short notice.

Programming and integrating the PLC

TwinCAT PLC Control is the development environment for the creation of the controller in different program
environments: TwinCAT PLC Control supports all languages described in IEC 61131-3. There are two text-
based languages and three graphical languages.
• Text-based languages
◦ Instruction List (IL)
◦ Structured Text (ST)

EL600x, EL602x Version: 4.6 61

Commissioning

• Graphical languages
◦ Function Block Diagram (FBD)
◦ Ladder Diagram (LD)
◦ The Continuous Function Chart Editor (CFC)
◦ Sequential Function Chart (SFC)

The following section refers to Structured Text (ST).

After starting TwinCAT PLC Control, the following user interface is shown for an initial project:

Fig. 51: Sample program with variables after a compile process (without variable integration)

Warning 1990 (missing "VAR_CONFIG") after a compile process indicates that the variables defined as
external (with the ID "AT%I*" or "AT%Q*") have not been assigned. After successful compilation, TwinCAT
PLC Control creates a "*.tpy" file in the directory in which the project was stored. This file (*.tpy) contains
variable assignments and is not known to the System Manager, hence the warning. Once the System
Manager has been notified, the warning no longer appears.

First, integrate the TwinCAT PLC Control project in the System Manager via the context menu of the PLC
configuration; right-click and select "Append PLC Project…":

Select the PLC configuration "PLC_example.tpy" in the browser window that opens. The project including the
two variables identified with "AT" are then integrated in the configuration tree of the System Manager:

Fig. 53: PLC project integrated in the PLC configuration of the System Manager

The two variables "bEL1004_Ch4" and "nEL2008_value" can now be assigned to certain process objects of
the I/O configuration.

Assigning variables

Open a window for selecting a suitable process object (PDO) via the context menu of a variable of the
integrated project "PLC_example" and via "Modify Link..." "Standard":

Fig. 55: Selecting PDO of type BOOL

According to the default setting, certain PDO objects are now available for selection. In this sample the input
of channel 4 of the EL1004 terminal is selected for linking. In contrast, the checkbox "All types" must be
ticked for creating the link for the output variables, in order to allocate a set of eight separate output bits to a
byte variable. The following diagram shows the whole process:

Fig. 56: Selecting several PDOs simultaneously: activate "Continuous" and "All types"

Note that the "Continuous" checkbox was also activated. This is designed to allocate the bits contained in the
byte of the variable "nEL2008_value" sequentially to all eight selected output bits of the EL2008 terminal. In
this way it is possible to subsequently address all eight outputs of the terminal in the program with a byte
corresponding to bit 0 for channel 1 to bit 7 for channel 8 of the PLC. A special symbol ( ) at the yellow or
red object of the variable indicates that a link exists. The links can also be checked by selecting a "Goto Link
Variable” from the context menu of a variable. The object opposite, in this case the PDO, is automatically
selected:

EL600x, EL602x Version: 4.6 65

Commissioning

Fig. 57: Application of a "Goto Link" variable, using "MAIN.bEL1004_Ch4" as a sample

The process of assigning variables to the PDO is completed via the menu selection "Actions" → "Generate

Mappings”, key Ctrl+M or by clicking on the symbol in the menu.

This can be visualized in the configuration:

The process of creating links can also take place in the opposite direction, i.e. starting with individual PDOs
to variable. However, in this example it would then not be possible to select all output bits for the EL2008,
since the terminal only makes individual digital outputs available. If a terminal has a byte, word, integer or
similar PDO, it is possible to allocate this a set of bit-standardised variables (type "BOOL"). Here, too, a
"Goto Link Variable” from the context menu of a PDO can be executed in the other direction, so that the
respective PLC instance can then be selected.

Activation of the configuration

The allocation of PDO to PLC variables has now established the connection from the controller to the inputs
and outputs of the terminals. The configuration can now be activated. First, the configuration can be verified

via (or via "Actions" → "Check Configuration”). If no error is present, the configuration can be

activated via (or via "Actions" → "Activate Configuration…") to transfer the System Manager settings
to the runtime system. Confirm the messages "Old configurations are overwritten!" and "Restart TwinCAT
system in Run mode" with "OK".

A few seconds later the real-time status is displayed at the bottom right in the System Manager.
The PLC system can then be started as described below.

Starting the controller

Starting from a remote system, the PLC control has to be linked with the Embedded PC over Ethernet via
"Online" → “Choose Run-Time System…":

In this sample "Runtime system 1 (port 801)" is selected and confirmed. Link the PLC with the real-time

system via menu option "Online" → "Login", the F11 key or by clicking on the symbol . The control
program can then be loaded for execution. This results in the message "No program on the controller!

5.1.2 TwinCAT 3

Startup

TwinCAT makes the development environment areas available together with Microsoft Visual Studio: after
startup, the project folder explorer appears on the left in the general window area (cf. "TwinCAT System
Manager" of TwinCAT 2) for communication with the electromechanical components.

After successful installation of the TwinCAT system on the PC to be used for development, TwinCAT 3
(shell) displays the following user interface after startup:

The new project is then available in the project folder explorer:

EL600x, EL602x Version: 4.6 69

Commissioning

Fig. 62: New TwinCAT3 project in the project folder explorer

Generally, TwinCAT can be used in local or remote mode. Once the TwinCAT system including the user
interface (standard) is installed on the respective PLC, TwinCAT can be used in local mode and thereby the
next step is "Insert Device [} 71]".

If the intention is to address the TwinCAT runtime environment installed on a PLC as development
environment remotely from another system, the target system must be made known first. Via the symbol in
the menu bar:

expand the pull-down menu:

and open the following window:

Use "Search (Ethernet)..." to enter the target system. Thus a next dialog opens to either:
• enter the known computer name after "Enter Host Name / IP:" (as shown in red)
• perform a "Broadcast Search" (if the exact computer name is not known)
• enter the known computer IP or AmsNetID.

Once the target system has been entered, it is available for selection as follows (a password may have to be
entered):

After confirmation with "OK" the target system can be accessed via the Visual Studio shell.

Adding devices

In the project folder explorer of the Visual Studio shell user interface on the left, select "Devices" within

element “I/O”, then right-click to open a context menu and select "Scan" or start the action via in the

menu bar. The TwinCAT System Manager may first have to be set to "Config mode" via or via the
menu "TwinCAT" → "Restart TwinCAT (Config mode)".

Programming the PLC

TwinCAT PLC Control is the development environment for the creation of the controller in different program
environments: TwinCAT PLC Control supports all languages described in IEC 61131-3. There are two text-
based languages and three graphical languages.
• Text-based languages
◦ Instruction List (IL)
◦ Structured Text (ST)
• Graphical languages
◦ Function Block Diagram (FBD)
◦ Ladder Diagram (LD)
◦ The Continuous Function Chart Editor (CFC)
◦ Sequential Function Chart (SFC)

The following section refers to Structured Text (ST).

In order to create a programming environment, a PLC subproject is added to the project sample via the
context menu of "PLC" in the project folder explorer by selecting "Add New Item….":

According to the default setting, certain PDO objects are now available for selection. In this sample the input
of channel 4 of the EL1004 terminal is selected for linking. In contrast, the checkbox "All types" must be
ticked for creating the link for the output variables, in order to allocate a set of eight separate output bits to a
byte variable. The following diagram shows the whole process:

EL600x, EL602x Version: 4.6 77

Commissioning

Fig. 76: Selecting several PDOs simultaneously: activate "Continuous" and "All types"

Note that the "Continuous" checkbox was also activated. This is designed to allocate the bits contained in the
byte of the variable "nEL2008_value" sequentially to all eight selected output bits of the EL2008 terminal. In
this way it is possible to subsequently address all eight outputs of the terminal in the program with a byte
corresponding to bit 0 for channel 1 to bit 7 for channel 8 of the PLC. A special symbol ( ) at the yellow or
red object of the variable indicates that a link exists. The links can also be checked by selecting a "Goto Link
Variable” from the context menu of a variable. The object opposite, in this case the PDO, is automatically
selected:

Fig. 77: Application of a "Goto Link" variable, using "MAIN.bEL1004_Ch4" as a sample

The process of creating links can also take place in the opposite direction, i.e. starting with individual PDOs
to variable. However, in this example it would then not be possible to select all output bits for the EL2008,
since the terminal only makes individual digital outputs available. If a terminal has a byte, word, integer or
similar PDO, it is possible to allocate this a set of bit-standardised variables (type "BOOL"). Here, too, a
"Goto Link Variable” from the context menu of a PDO can be executed in the other direction, so that the
respective PLC instance can then be selected.

Activation of the configuration

The allocation of PDO to PLC variables has now established the connection from the controller to the inputs

and outputs of the terminals. The configuration can now be activated with or via the menu under
"TwinCAT" in order to transfer settings of the development environment to the runtime system. Confirm the
messages "Old configurations are overwritten!" and "Restart TwinCAT system in Run mode" with "OK". The
corresponding assignments can be seen in the project folder explorer:

A few seconds later the corresponding status of the Run mode is displayed in the form of a rotating symbol

at the bottom right of the VS shell development environment. The PLC system can then be started as
described below.

Starting the controller

Select the menu option "PLC" → "Login" or click on to link the PLC with the real-time system and load
the control program for execution. This results in the message "No program on the controller! Should the
new program be loaded?", which should be acknowledged with "Yes". The runtime environment is ready for

program start by click on symbol , the "F5" key or via "PLC" in the menu selecting “Start”. The started
programming environment shows the runtime values of individual variables:

5.2.1 Installation of the TwinCAT real-time driver

In order to assign real-time capability to a standard Ethernet port of an IPC controller, the Beckhoff real-time
driver has to be installed on this port under Windows.

This can be done in several ways. One option is described here.

In the System Manager call up the TwinCAT overview of the local network interfaces via Options → Show
Real Time Ethernet Compatible Devices.

The following dialog appears:

Fig. 81: Overview of network interfaces

Interfaces listed under “Compatible devices” can be assigned a driver via the “Install” button. A driver should
only be installed on compatible devices.

A Windows warning regarding the unsigned driver can be ignored.

Alternatively an EtherCAT-device can be inserted first of all as described in chapter Offline configuration
creation, section “Creating the EtherCAT device” [} 91] in order to view the compatible ethernet ports via its
EtherCAT properties (tab „Adapter“, button „Compatible Devices…“):

IP address of the port used

IP address/DHCP
In most cases an Ethernet port that is configured as an EtherCAT device will not transport general
IP packets. For this reason and in cases where an EL6601 or similar devices are used it is useful to
specify a fixed IP address for this port via the “Internet Protocol TCP/IP” driver setting and to disable
DHCP. In this way the delay associated with the DHCP client for the Ethernet port assigning itself a
default IP address in the absence of a DHCP server is avoided. A suitable address space is
192.168.x.x, for example.

5.2.2 Notes regarding ESI device description

Installation of the latest ESI device description

The TwinCAT EtherCAT master/System Manager needs the device description files for the devices to be
used in order to generate the configuration in online or offline mode. The device descriptions are contained
in the so-called ESI files (EtherCAT Slave Information) in XML format. These files can be requested from the
respective manufacturer and are made available for download. An *.xml file may contain several device
descriptions.

The ESI files for Beckhoff EtherCAT devices are available on the Beckhoff website.

The ESI files should be stored in the TwinCAT installation directory.

Default settings:
• TwinCAT 2: C:\TwinCAT\IO\EtherCAT
• TwinCAT 3: C:\TwinCAT\3.1\Config\Io\EtherCAT

The files are read (once) when a new System Manager window is opened, if they have changed since the
last time the System Manager window was opened.

A TwinCAT installation includes the set of Beckhoff ESI files that was current at the time when the TwinCAT
build was created.

For TwinCAT 2.11/TwinCAT 3 and higher, the ESI directory can be updated from the System Manager, if the
programming PC is connected to the Internet; by
• TwinCAT 2: Option → “Update EtherCAT Device Descriptions”
• TwinCAT 3: TwinCAT → EtherCAT Devices → “Update Device Descriptions (via ETG Website)…”

The TwinCAT ESI Updater [} 90] is available for this purpose.

ESI
The *.xml files are associated with *.xsd files, which describe the structure of the ESI XML files. To
update the ESI device descriptions, both file types should therefore be updated.

Device differentiation

EtherCAT devices/slaves are distinguished by four properties, which determine the full device identifier. For
example, the device identifier EL2521-0025-1018 consists of:
• family key “EL”
• name “2521”
• type “0025”
• and revision “1018”

Fig. 87: Identifier structure

The order identifier consisting of name + type (here: EL2521-0010) describes the device function. The
revision indicates the technical progress and is managed by Beckhoff. In principle, a device with a higher
revision can replace a device with a lower revision, unless specified otherwise, e.g. in the documentation.
Each revision has its own ESI description. See further notes [} 9].

86 Version: 4.6 EL600x, EL602x

 Commissioning

Online description

If the EtherCAT configuration is created online through scanning of real devices (see section Online setup)
and no ESI descriptions are available for a slave (specified by name and revision) that was found, the
System Manager asks whether the description stored in the device should be used. In any case, the System
Manager needs this information for setting up the cyclic and acyclic communication with the slave correctly.

Fig. 88: OnlineDescription information window (TwinCAT 2)

In TwinCAT 3 a similar window appears, which also offers the Web update:

Fig. 89: Information window OnlineDescription (TwinCAT 3)

If possible, the Yes is to be rejected and the required ESI is to be requested from the device manufacturer.
After installation of the XML/XSD file the configuration process should be repeated.

NOTE
Changing the ‘usual’ configuration through a scan
ü If a scan discovers a device that is not yet known to TwinCAT, distinction has to be made between two
cases. Taking the example here of the EL2521-0000 in the revision 1019
a) no ESI is present for the EL2521-0000 device at all, either for the revision 1019 or for an older revision.
The ESI must then be requested from the manufacturer (in this case Beckhoff).
b) an ESI is present for the EL2521-0000 device, but only in an older revision, e.g. 1018 or 1017.
In this case an in-house check should first be performed to determine whether the spare parts stock al-
lows the integration of the increased revision into the configuration at all. A new/higher revision usually
also brings along new features. If these are not to be used, work can continue without reservations with
the previous revision 1018 in the configuration. This is also stated by the Beckhoff compatibility rule.

Refer in particular to the chapter ‘General notes on the use of Beckhoff EtherCAT IO components’ and for
manual configuration to the chapter ‘Offline configuration creation’ [} 91].

If the OnlineDescription is used regardless, the System Manager reads a copy of the device description from
the EEPROM in the EtherCAT slave. In complex slaves the size of the EEPROM may not be sufficient for the
complete ESI, in which case the ESI would be incomplete in the configurator. Therefore it’s recommended
using an offline ESI file with priority in such a case.

The System Manager creates for online recorded device descriptions a new file
“OnlineDescription0000...xml” in its ESI directory, which contains all ESI descriptions that were read online.

EL600x, EL602x Version: 4.6 87

Commissioning

Fig. 90: File OnlineDescription.xml created by the System Manager

Is a slave desired to be added manually to the configuration at a later stage, online created slaves are
indicated by a prepended symbol “>” in the selection list (see Figure “Indication of an online recorded ESI of
EL2521 as an example”).

Fig. 91: Indication of an online recorded ESI of EL2521 as an example

If such ESI files are used and the manufacturer's files become available later, the file OnlineDescription.xml
should be deleted as follows:
• close all System Manager windows
• restart TwinCAT in Config mode
• delete "OnlineDescription0000...xml"
• restart TwinCAT System Manager

This file should not be visible after this procedure, if necessary press <F5> to update

OnlineDescription for TwinCAT 3.x

In addition to the file described above "OnlineDescription0000...xml" , a so called EtherCAT cache
with new discovered devices is created by TwinCAT 3.x, e.g. under Windows 7:

(Please note the language settings of the OS!)

You have to delete this file, too.

Faulty ESI file

If an ESI file is faulty and the System Manager is unable to read it, the System Manager brings up an
information window.

5.2.3 TwinCAT ESI Updater

For TwinCAT 2.11 and higher, the System Manager can search for current Beckhoff ESI files automatically, if
an online connection is available:

Fig. 93: Using the ESI Updater (>= TwinCAT 2.11)

The call up takes place under:

“Options” → "Update EtherCAT Device Descriptions"

Selection under TwinCAT 3:

Fig. 94: Using the ESI Updater (TwinCAT 3)

The ESI Updater (TwinCAT 3) is a convenient option for automatic downloading of ESI data provided by
EtherCAT manufacturers via the Internet into the TwinCAT directory (ESI = EtherCAT slave information).
TwinCAT accesses the central ESI ULR directory list stored at ETG; the entries can then be viewed in the
Updater dialog, although they cannot be changed there.

The call up takes place under:

“TwinCAT“ → „EtherCAT Devices“ → “Update Device Description (via ETG Website)…“.

5.2.4 Distinction between Online and Offline

The distinction between online and offline refers to the presence of the actual I/O environment (drives,
terminals, EJ-modules). If the configuration is to be prepared in advance of the system configuration as a
programming system, e.g. on a laptop, this is only possible in “Offline configuration” mode. In this case all
components have to be entered manually in the configuration, e.g. based on the electrical design.

If the designed control system is already connected to the EtherCAT system and all components are
energised and the infrastructure is ready for operation, the TwinCAT configuration can simply be generated
through “scanning” from the runtime system. This is referred to as online configuration.

In any case, during each startup the EtherCAT master checks whether the slaves it finds match the
configuration. This test can be parameterised in the extended slave settings. Refer to note “Installation of
the latest ESI-XML device description” [} 86].

For preparation of a configuration:

• the real EtherCAT hardware (devices, couplers, drives) must be present and installed
• the devices/modules must be connected via EtherCAT cables or in the terminal/ module strand in the
same way as they are intended to be used later

90 Version: 4.6 EL600x, EL602x

 Commissioning

• the devices/modules be connected to the power supply and ready for communication
• TwinCAT must be in CONFIG mode on the target system.

The online scan process consists of:

• detecting the EtherCAT device [} 96] (Ethernet port at the IPC)
• detecting the connected EtherCAT devices [} 97]. This step can be carried out independent of the
preceding step
• troubleshooting [} 100]

The scan with existing configuration [} 101] can also be carried out for comparison.

The dialog for selecting a new device opens. Only devices for which ESI files are available are displayed.

Only devices are offered for selection that can be appended to the previously selected device. Therefore the
physical layer available for this port is also displayed (Fig. “Selection dialog for new EtherCAT device”, A). In
the case of cable-based Fast-Ethernet physical layer with PHY transfer, then also only cable-based devices
are available, as shown in Fig. “Selection dialog for new EtherCAT device”. If the preceding device has
several free ports (e.g. EK1122 or EK1100), the required port can be selected on the right-hand side (A).

By default only the name/device type is used as selection criterion. For selecting a specific revision of the
device the revision can be displayed as “Extended Information”.

Fig. 101: Display of device revision

In many cases several device revisions were created for historic or functional reasons, e.g. through
technological advancement. For simplification purposes (see Fig. “Selection dialog for new EtherCAT
device”) only the last (i.e. highest) revision and therefore the latest state of production is displayed in the
selection dialog for Beckhoff devices. To show all device revisions available in the system as ESI
descriptions tick the “Show Hidden Devices” check box, see Fig. “Display of previous revisions”.

Fig. 102: Display of previous revisions

Device selection based on revision, compatibility

The ESI description also defines the process image, the communication type between master and
slave/device and the device functions, if applicable. The physical device (firmware, if available) has
to support the communication queries/settings of the master. This is backward compatible, i.e.
newer devices (higher revision) should be supported if the EtherCAT master addresses them as an
older revision. The following compatibility rule of thumb is to be assumed for Beckhoff EtherCAT
Terminals/ Boxes/ EJ-modules:
device revision in the system >= device revision in the configuration
This also enables subsequent replacement of devices without changing the configuration (different
specifications are possible for drives).

Example:

If an EL2521-0025-1018 is specified in the configuration, an EL2521-0025-1018 or higher (-1019, -1020) can

be used in practice.

Fig. 103: Name/revision of the terminal

If current ESI descriptions are available in the TwinCAT system, the last revision offered in the selection
dialog matches the Beckhoff state of production. It is recommended to use the last device revision when
creating a new configuration, if current Beckhoff devices are used in the real application. Older revisions
should only be used if older devices from stock are to be used in the application.

In this case the process image of the device is shown in the configuration tree and can be parameterised as
follows: linking with the task, CoE/DC settings, plug-in definition, startup settings, ...

Online scanning in Config mode

The online search is not available in RUN mode (production operation). Note the differentiation be-
tween TwinCAT programming system and TwinCAT target system.

The TwinCAT 2 icon ( ) or TwinCAT 3 icon ( ) within the Windows-Taskbar always shows the
TwinCAT mode of the local IPC. Compared to that, the System Manager window of TwinCAT 2 or the user
interface of TwinCAT 3 indicates the state of the target system.

This scan mode attempts to find not only EtherCAT devices (or Ethernet ports that are usable as such), but
also NOVRAM, fieldbus cards, SMB etc. However, not all devices can be found automatically.

Ethernet ports with installed TwinCAT real-time driver are shown as “RT Ethernet” devices. An EtherCAT
frame is sent to these ports for testing purposes. If the scan agent detects from the response that an
EtherCAT slave is connected, the port is immediately shown as an “EtherCAT Device” .

Fig. 108: Detected Ethernet devices

Via respective checkboxes devices can be selected (as illustrated in Fig. “Detected Ethernet devices” e.g.
Device 3 and Device 4 were chosen). After confirmation with “OK” a device scan is suggested for all selected
devices, see Fig.: “Scan query after automatic creation of an EtherCAT device”.

Selecting the Ethernet port

Ethernet ports can only be selected for EtherCAT devices for which the TwinCAT real-time driver is
installed. This has to be done separately for each port. Please refer to the respective installation
page [} 80].

Detecting/Scanning the EtherCAT devices

Online scan functionality

During a scan the master queries the identity information of the EtherCAT slaves from the slave
EEPROM. The name and revision are used for determining the type. The respective devices are lo-
cated in the stored ESI data and integrated in the configuration tree in the default state defined
there.

Fig. 109: Example default state

NOTE
Slave scanning in practice in series machine production
The scanning function should be used with care. It is a practical and fast tool for creating an initial configu-
ration as a basis for commissioning. In series machine production or reproduction of the plant, however, the
function should no longer be used for the creation of the configuration, but if necessary for comparison
[} 101] with the defined initial configuration.Background: since Beckhoff occasionally increases the revision
version of the delivered products for product maintenance reasons, a configuration can be created by such
a scan which (with an identical machine construction) is identical according to the device list; however, the
respective device revision may differ from the initial configuration.

Example:

Company A builds the prototype of a machine B, which is to be produced in series later on. To do this the
prototype is built, a scan of the IO devices is performed in TwinCAT and the initial configuration ‘B.tsm’ is
created. The EL2521-0025 EtherCAT terminal with the revision 1018 is located somewhere. It is thus built
into the TwinCAT configuration in this way:

EL600x, EL602x Version: 4.6 97

Commissioning

Fig. 110: Installing EthetCAT terminal with revision -1018

Likewise, during the prototype test phase, the functions and properties of this terminal are tested by the
programmers/commissioning engineers and used if necessary, i.e. addressed from the PLC ‘B.pro’ or the
NC. (the same applies correspondingly to the TwinCAT 3 solution files).

The prototype development is now completed and series production of machine B starts, for which Beckhoff
continues to supply the EL2521-0025-0018. If the commissioning engineers of the series machine production
department always carry out a scan, a B configuration with the identical contents results again for each
machine. Likewise, A might create spare parts stores worldwide for the coming series-produced machines
with EL2521-0025-1018 terminals.

After some time Beckhoff extends the EL2521-0025 by a new feature C. Therefore the FW is changed,
outwardly recognizable by a higher FW version and a new revision -1019. Nevertheless the new device
naturally supports functions and interfaces of the predecessor version(s); an adaptation of ‘B.tsm’ or even
‘B.pro’ is therefore unnecessary. The series-produced machines can continue to be built with ‘B.tsm’ and
‘B.pro’; it makes sense to perform a comparative scan [} 101] against the initial configuration ‘B.tsm’ in order
to check the built machine.

However, if the series machine production department now doesn’t use ‘B.tsm’, but instead carries out a
scan to create the productive configuration, the revision -1019 is automatically detected and built into the
configuration:

Fig. 111: Detection of EtherCAT terminal with revision -1019

This is usually not noticed by the commissioning engineers. TwinCAT cannot signal anything either, since
virtually a new configuration is created. According to the compatibility rule, however, this means that no
EL2521-0025-1018 should be built into this machine as a spare part (even if this nevertheless works in the
vast majority of cases).

In addition, it could be the case that, due to the development accompanying production in company A, the
new feature C of the EL2521-0025-1019 (for example, an improved analog filter or an additional process
data for the diagnosis) is discovered and used without in-house consultation. The previous stock of spare
part devices are then no longer to be used for the new configuration ‘B2.tsm’ created in this way.Þ if series
machine production is established, the scan should only be performed for informative purposes for
comparison with a defined initial configuration. Changes are to be made with care!

If an EtherCAT device was created in the configuration (manually or through a scan), the I/O field can be
scanned for devices/slaves.

Troubleshooting

Various effects may occur during scanning.

• An unknown device is detected, i.e. an EtherCAT slave for which no ESI XML description is available.
In this case the System Manager offers to read any ESI that may be stored in the device. This case is
described in the chapter "Notes regarding ESI device description".
• Device are not detected properly
Possible reasons include:
- faulty data links, resulting in data loss during the scan
- slave has invalid device description
The connections and devices should be checked in a targeted manner, e.g. via the emergency scan.
Then re-run the scan.

Scan over existing Configuration

NOTE
Change of the configuration after comparison
With this scan (TwinCAT 2.11 or 3.1) only the device properties vendor (manufacturer), device name and
revision are compared at present! A ‘ChangeTo’ or ‘Copy’ should only be carried out with care, taking into
consideration the Beckhoff IO compatibility rule (see above). The device configuration is then replaced by
the revision found; this can affect the supported process data and functions.

If a scan is initiated for an existing configuration, the actual I/O environment may match the configuration
exactly or it may differ. This enables the configuration to be compared.

blue This EtherCAT slave is present on the other side, but in a different revision. This other
revision can have other default values for the process data as well as other/additional
functions.
If the found revision is higher than the configured revision, the slave may be used provided
compatibility issues are taken into account.
If the found revision is lower than the configured revision, it is likely that the slave cannot be
used. The found device may not support all functions that the master expects based on the
higher revision number.
light blue This EtherCAT slave is ignored (“Ignore” button)
red • This EtherCAT slave is not present on the other side.
• It is present, but in a different revision, which also differs in its properties from the one
specified.
The compatibility principle then also applies here: if the found revision is higher than the
configured revision, use is possible provided compatibility issues are taken into account,
since the successor devices should support the functions of the predecessor devices.
If the found revision is lower than the configured revision, it is likely that the slave cannot
be used. The found device may not support all functions that the master expects based on
the higher revision number.

Device selection based on revision, compatibility

The ESI description also defines the process image, the communication type between master and
slave/device and the device functions, if applicable. The physical device (firmware, if available) has
to support the communication queries/settings of the master. This is backward compatible, i.e.
newer devices (higher revision) should be supported if the EtherCAT master addresses them as an
older revision. The following compatibility rule of thumb is to be assumed for Beckhoff EtherCAT
Terminals/ Boxes/ EJ-modules:
device revision in the system >= device revision in the configuration
This also enables subsequent replacement of devices without changing the configuration (different
specifications are possible for drives).

Example:

If an EL2521-0025-1018 is specified in the configuration, an EL2521-0025-1018 or higher (-1019, -1020) can

be used in practice.

Fig. 122: Name/revision of the terminal

If current ESI descriptions are available in the TwinCAT system, the last revision offered in the selection
dialog matches the Beckhoff state of production. It is recommended to use the last device revision when
creating a new configuration, if current Beckhoff devices are used in the real application. Older revisions
should only be used if older devices from stock are to be used in the application.

In this case the process image of the device is shown in the configuration tree and can be parameterised as
follows: linking with the task, CoE/DC settings, plug-in definition, startup settings, ...

If called, the System Manager searches in the procured device ESI (in this example: EL1202-0000) for
details of compatible devices contained there. The configuration is changed and the ESI-EEPROM is
overwritten at the same time – therefore this process is possible only in the online state (ConfigMode).

Commissioning

Fig. 129: “Process Data” tab

The process data (PDOs) transferred by an EtherCAT slave during each cycle are user data which the
application expects to be updated cyclically or which are sent to the slave. To this end the EtherCAT master
(Beckhoff TwinCAT) parameterizes each EtherCAT slave during the start-up phase to define which process
data (size in bits/bytes, source location, transmission type) it wants to transfer to or from this slave. Incorrect
configuration can prevent successful start-up of the slave.

For Beckhoff EtherCAT EL, ES, EM, EJ and EP slaves the following applies in general:
• The input/output process data supported by the device are defined by the manufacturer in the ESI/XML
description. The TwinCAT EtherCAT Master uses the ESI description to configure the slave correctly.
• The process data can be modified in the system manager. See the device documentation.
Examples of modifications include: mask out a channel, displaying additional cyclic information, 16-bit
display instead of 8-bit data size, etc.
• In so-called “intelligent” EtherCAT devices the process data information is also stored in the CoE
directory. Any changes in the CoE directory that lead to different PDO settings prevent successful
startup of the slave. It is not advisable to deviate from the designated process data, because the
device firmware (if available) is adapted to these PDO combinations.

If the device documentation allows modification of process data, proceed as follows (see Figure “Configuring
the process data”).
• A: select the device to configure
• B: in the “Process Data” tab select Input or Output under SyncManager (C)
• D: the PDOs can be selected or deselected
• H: the new process data are visible as linkable variables in the system manager
The new process data are active once the configuration has been activated and TwinCAT has been
restarted (or the EtherCAT master has been restarted)
• E: if a slave supports this, Input and Output PDO can be modified simultaneously by selecting a so-
called PDO record (“predefined PDO settings”).

Manual modification of the process data

According to the ESI description, a PDO can be identified as “fixed” with the flag “F” in the PDO
overview (Fig. “Configuring the process data”, J). The configuration of such PDOs cannot be
changed, even if TwinCAT offers the associated dialog (“Edit”). In particular, CoE content cannot be
displayed as cyclic process data. This generally also applies in cases where a device supports
download of the PDO configuration, “G”. In case of incorrect configuration the EtherCAT slave usu-
ally refuses to start and change to OP state. The System Manager displays an “invalid SM cfg” log-
ger message: This error message (“invalid SM IN cfg” or “invalid SM OUT cfg”) also indicates the
reason for the failed start.

5.3 General Notes - EtherCAT Slave Application

This summary briefly deals with a number of aspects of EtherCAT Slave operation under TwinCAT. More
detailed information on this may be found in the corresponding sections of, for instance, the EtherCAT
System Documentation.

Diagnosis in real time: WorkingCounter, EtherCAT State and Status

Generally speaking an EtherCAT Slave provides a variety of diagnostic information that can be used by the
controlling task.

This diagnostic information relates to differing levels of communication. It therefore has a variety of sources,
and is also updated at various times.

Any application that relies on I/O data from a fieldbus being correct and up to date must make diagnostic
access to the corresponding underlying layers. EtherCAT and the TwinCAT System Manager offer
comprehensive diagnostic elements of this kind. Those diagnostic elements that are helpful to the controlling
task for diagnosis that is accurate for the current cycle when in operation (not during commissioning) are
discussed below.

Fig. 136: Selection of the diagnostic information of an EtherCAT Slave

In general, an EtherCAT Slave offers

• communication diagnosis typical for a slave (diagnosis of successful participation in the exchange of
process data, and correct operating mode)
This diagnosis is the same for all slaves.

as well as
• function diagnosis typical for a channel (device-dependent)
See the corresponding device documentation

The colors in Fig. “Selection of the diagnostic information of an EtherCAT Slave” also correspond to the
variable colors in the System Manager, see Fig. “Basic EtherCAT Slave Diagnosis in the PLC”.

Colour Meaning
yellow Input variables from the Slave to the EtherCAT Master, updated in every cycle
red Output variables from the Slave to the EtherCAT Master, updated in every cycle
green Information variables for the EtherCAT Master that are updated acyclically. This means that
it is possible that in any particular cycle they do not represent the latest possible status. It is
therefore useful to read such variables through ADS.

EtherCAT Slave Diagnosis. A Beckhoff EL3102 (2-channel analogue input terminal) is used here, as it offers

CoE Parameter Directory

The CoE parameter directory (CanOpen-over-EtherCAT) is used to manage the set values for the slave
concerned. Changes may, in some circumstances, have to be made here when commissioning a relatively
complex EtherCAT Slave. It can be accessed through the TwinCAT System Manager, see Fig. “EL3102,
CoE directory”:

EtherCAT System Documentation

The comprehensive description in the EtherCAT System Documentation (EtherCAT Basics --> CoE
Interface) must be observed!

A few brief extracts:

• Whether changes in the online directory are saved locally in the slave depends on the device. EL
terminals (except the EL66xx) are able to save in this way.
• The user must manage the changes to the StartUp list.

Commissioning aid in the TwinCAT System Manager

Commissioning interfaces are being introduced as part of an ongoing process for EL/EP EtherCAT devices.
These are available in TwinCAT System Managers from TwinCAT 2.11R2 and above. They are integrated
into the System Manager through appropriately extended ESI configuration files.

EL600x, EL602x Version: 4.6 117

Commissioning

Fig. 139: Example of commissioning aid for a EL3204

This commissioning process simultaneously manages

• CoE Parameter Directory
• DC/FreeRun mode
• the available process data records (PDO)

Although the "Process Data", "DC", "Startup" and "CoE-Online" that used to be necessary for this are still
displayed, it is recommended that, if the commissioning aid is used, the automatically generated settings are
not changed by it.

The commissioning tool does not cover every possible application of an EL/EP device. If the available setting
options are not adequate, the user can make the DC, PDO and CoE settings manually, as in the past.

EtherCAT State: automatic default behaviour of the TwinCAT System Manager and manual operation

After the operating power is switched on, an EtherCAT Slave must go through the following statuses
• INIT
• PREOP
• SAFEOP
• OP

to ensure sound operation. The EtherCAT Master directs these statuses in accordance with the initialization
routines that are defined for commissioning the device by the ES/XML and user settings (Distributed Clocks
(DC), PDO, CoE). See also the section on "Principles of Communication, EtherCAT State Machine [} 25]" in
this connection. Depending how much configuration has to be done, and on the overall communication,
booting can take up to a few seconds.

The EtherCAT Master itself must go through these routines when starting, until it has reached at least the
OP target state.

The target state wanted by the user, and which is brought about automatically at start-up by TwinCAT, can
be set in the System Manager. As soon as TwinCAT reaches the status RUN, the TwinCAT EtherCAT
Master will approach the target states.

Standard setting

The advanced settings of the EtherCAT Master are set as standard:

• EtherCAT Master: OP
• Slaves: OP
This setting applies equally to all Slaves.

In addition, the target state of any particular Slave can be set in the "Advanced Settings" dialogue; the
standard setting is again OP.

Manual Control

There are particular reasons why it may be appropriate to control the states from the application/task/PLC.
For instance:
• for diagnostic reasons
• to induce a controlled restart of axes
• because a change in the times involved in starting is desirable

In that case it is appropriate in the PLC application to use the PLC function blocks from the TcEtherCAT.lib,
which is available as standard, and to work through the states in a controlled manner using, for instance,
FB_EcSetMasterState.

It is then useful to put the settings in the EtherCAT Master to INIT for master and slave.

Note regarding E-Bus current

EL/ES terminals are placed on the DIN rail at a coupler on the terminal strand. A Bus Coupler can supply the
EL terminals added to it with the E-bus system voltage of 5 V; a coupler is thereby loadable up to 2 A as a
rule. Information on how much current each EL terminal requires from the E-bus supply is available online
and in the catalogue. If the added terminals require more current than the coupler can supply, then power
feed terminals (e.g. EL9410) must be inserted at appropriate places in the terminal strand.

The pre-calculated theoretical maximum E-Bus current is displayed in the TwinCAT System Manager as a
column value. A shortfall is marked by a negative total amount and an exclamation mark; a power feed
terminal is to be placed before such a position.

StartUp list entry

For the EL6001/EL6021 with hardware < 03, the startUp entries can only be set in the transition
from SafeOP to OP (S -> O). The default setting is PreOP -> SafeOP (P -> S). When creating
StartUp entries, ensure that the checkbox "S -> O" is ticked (see Fig.)!

Process data

As delivered, 22 bytes of user data and 1 control/status word are transferred.

The process data are generated from CoE objects 0x6000 (Inputs) and 0x7000 (Outputs) and are described
in chapter Object description and parameterization [} 168] in detail.

Enlarged process image 50x 16-bit

An enlarged process data interface is necessary for communication with >8 data bits. If the terminal supports
this (see Communication features [} 131]) a 50-word interface can be set as an alternative to the 22-byte
interface (PDOs 0x1605 and 0x1A05). This can be used with every encryption regulation (7xx, 8xx), but only
makes sense with a regulation >8 bits, e.g. 9N1. In each case the least significant bits must be occupied by
the data bits, i.e. in the case of 9N1 the 9 least significant bits in the data words.

Features and application notes

Optional features are generally set in the CoE directory (CAN over EtherCAT, index 0x80n0).

Parameterization via the CoE list (CAN over EtherCAT)

Please note the following general CoE information when using/manipulating the CoE parameters: -
Keep a startup list if components have to be replaced - Differentiate between online/offline dictio-
nary, ensure existence of current XML description - use “CoE reload” for resetting changes Please
note especially for the EL60xx, if any changes are made to the communication settings (baud rate,
data frame, feature bits), an InitRequest via the control word is required to apply the changes.

EL600x, EL602x Version: 4.6 125

Commissioning

The following CoE settings are possible from object 0x8000 and are shown below in their default settings:

Fig. 146: “CoE - Online, EL60x4 terminals” tab

Transfer rates

The terminal has a process image of 22 bytes of user data. It possible to transmit or receive these 22 bytes
every second cycle at the most.
The data is transferred from the terminal to the controller in the first cycle. In the second cycle, the controller
must acknowledge that it has accepted the data.
Therefore, if the cycle time is 10 ms, 50 times 22 bytes can be transmitted per second.

With a set data frame of 8N1, each transmitted byte consists of a start bit, eight data bits and a stop bit. This
is equivalent to 10 bits per user byte.

With the above mentioned settings, a continuous data transfer rate of:
 •    50[1/s]*22[Byte]*10[Bit] = 11000 bps
can be achieved.

The next lower baud rate is 9600 baud. Accordingly, continuous transfer at a maximum baud rate of 9600
can be secured with a cycle time of 10 ms.

From firmware 11 the CoE 0x8000:1B supports with explicitBaudrate all baud rates 1000…115200 baud.
When the baud rate is selected, the compatibility of the remote station to the set baud rate must be taken
into account.
If only low quantities of data are to be transmitted or received sporadically (e.g. bar code scanner) the baud
rate can also be set higher, or the cycle time can be enlarged.
If the controller cannot fetch the data quickly enough from the terminal, the data will be stored intermediately
in the internal buffer of the terminal. The buffer for received data has a size of 864 bytes. If this is exhausted,
all further data will be lost.

Another scenario: the controller transfers significantly more data to the terminal than the latter can transmit.
For a ‘baud rate’ setting of 300 and a ‘data frame’ setting of 8N1, the terminal can only transmit 30 bytes per
second. However, if more than these 30 bytes per second are received, a 128 byte transmit buffer will be
written to first in this case also. Once this is full, all further data will be lost.

126 Version: 4.6 EL600x, EL602x

 Commissioning

Optimization of transfer rates

In normal operating mode the data received will be adopted immediately into the process image. In order to
enable a continuous flow of data, the ‘Enable transfer rate optimization’ option in the Settings object is
activated as standard. Due to this switch, the data will first be stored intermediately in the receive buffer
(864 bytes).

The data will only be copied into the process image if no further character is received for 16 bit periods or if
the buffer is full.

Continuous transmission of data

Usually the EL60xx terminal automatically decides when to send the data bytes contained in the buffer. For
many applications it is helpful to have a continuous data stream. For this purpose, the Beckhoff EL60xx
terminals feature the ‘Enable send FIFO data continuous’ setting in the Settings object. If this switch is set.
• The internal send buffer (128 bytes) must be filled first. To this end, data will be sent from the controller
to the terminal as in a normal data transfer.
• Data transfer from the buffer commences with a rising edge of the bit “Send continuous”
• If the data has been transferred, the terminal informs the controller by setting the “InitAccepted” bit. “Init
accepted” is cleared with “Send continuous”.

This setting enables up to 128 bytes to be transferred without long delays, even with slower EtherCAT cycle
times and high baud rates.

The terminal tries to leave as little distance as possible between the telegrams by seamlessly following each
stop bit with the next start bit. Nevertheless, in two-channel mode high baud rates may result in short pauses
between telegrams. A 20-byte data block may be sent in two blocks of 5 and 15 or 7 and 13 telegrams, for
example, or with a different distribution. In a two-channel terminal channel 1 is given priority.

Prioritization

Since received data normally cannot be repeated, it has a higher priority than data to be transmitted.
Furthermore, the priority decreases as the channel number increases. Hence, the reception of data on
channel 1 has the highest priority.

Command mode

From firmware 06 / revision -0018 the EL6021 supports the so-called command mode. Certain terminal
functions can be used and controlled through optional combination and/or sequence of commands. The
following functions are currently supported:
• Multi-data frame feature: (from firmware 06) change of coding during ongoing data communication
(sending)
To this end the send buffer of the terminal should be filled with the bytes to be sent (note the maximum
buffer size). As soon as the send process is started via the control word, the first n bytes are sent
based on coding A, the remaining bytes in the buffer are sent with coding B. The buffer can then be
refilled and sent accordingly. Example: The first byte is sent with mark parity, the remaining bytes with
space parity.
Sequence:
◦ After each startup/restart of the EL60xx EtherCAT slave the parameterization has to be repeated.
The command function is not stored in the event of a power failure.
◦ Activation of SendContinuous mode through writing of 0x1 after 0x8000:04
◦ Activation of the multi-data frame feature through writing of 0x2001 after request 0xB000:01

◦ Specify coding A through writing of 0x2100 + [date frame code] after 0xB000:01

◦ Specify n bytes to be sent in coding A through writing of 0x2200 + [n] after 0xB000:01
Check that 0xB000:02 = 0
◦ Specify coding B through writing of 0x2300 + [date frame code] after 0xB000:01

Initialization

Initialization is performed prior to the first transmission/reception. The terminal is thereby parameterized with
the data from the corresponding Settings object.

Procedure:

1. Set “Init request” to 1

2. The terminal confirms successful initialization by setting “Init accepted”
3. Reset “Init request”
4. The terminal sets “Init accepted” to 0

The terminal is now ready for data exchange.

Data transmission from the controller to the terminal (send 2 characters)

1. Set “Output length” to 2

2. Fill “Data Out 0” and “Data Out 1” with user data
3. Change the state of “Transmit request”
4. The terminal acknowledges receipt of the data by changing the state of the “Transmit accepted” bit.

Data transmission from the terminal to the controller (receive characters)

1. The terminal indicates that there is new data in the process image by changing the state of the “Re-
ceive request” bit.
2. The number of bytes received is written in “Input length”
3. The controller acknowledges acceptance of the bytes by changing the state of “Receive request”

5.5 Hints regarding TcVirtualComDriver

In case the EL60xx is to cooperate with the TwinCAT Virtual Serial COM Driver, here are a few hints:

Usually the customer-specific higher-level Windows application sets the desired feature of the COM interface
according to the application, e.g. 2400 baud and 7N2 coding. Therefore, the customer-specific entries made
before parameterization in the CoE StartUp entries, the Settings dialogue, the VirtualComPort or the device
CoE are usually irrelevant.

Fig. 147: Each higher level (if available or activated) dictates the communication features to the level below
it.

NOTE
TcVirtualComDriver version
Check whether the desired Baud rate/coding combination of the TcVirtualComDriver version and EL/EP ter-
minal used by you is also supported. If this is not the case:
   ● it may not be possible to open the COM port
   ● an ADS error message may appear in the ADS logger in the System Manager
   ● a CoE error message may appear in the ADS logger
The TcVirtualComDriver supports ExplicitBaudrate (CoE 0x80n0:1B) from version 1.18.

If the COM application has then set the features (such as baud rate) during the runtime, the correct setting
can be checked against it in the Online CoE, see fig.

5.7 LIN Master Feature EL6001

Description of “LIN master support”

The EL6001 realizes a bus interface for RS232 levels. From software version 10, the EL6001 features an
auxiliary function for sending and receiving LIN telegrams. This function does not cover the formal treatment
of the protocol layers for LIN (“protocol stack”) or a physical LIN connection. Instead, the EL6001 can deal
with the prolonged start/end mark of a LIN telegram in write and read direction.

132 Version: 4.6 EL600x, EL602x

 Commissioning

”Above” the terminal a LIN stack is required that is implemented in the PLC, for example, below the terminal
an RS232 <-> 5/12 V level converter is required.

Before using this function, please check the suitability in your system, since the EL6001 does not have a fully
comprehensive LIN implementation!

A complete LIN frame results from a master query with directly following slave response. As master
operating, the terminal sends the master frame and receives the slave data. With activated LIN functionality
of the EL6001 (since FW10) a “sync break” and a “sync byte” is always output before the “protected
identifier” (PID). In fact this terminal is therefore able to operate as a data receiving slave, too, but not as a
data sending slave node.

Activation

The addition of a “sync break” and “sync field” for sending, which is required for LIN, can be activated via the
“Command” object. To this end, enter the value 0x3000 in the CoE object 0xB000:01 [} 164]. The response
can be read in CoE object 0xB000:03 with the values 0x01 0x00 0x00 0x4C 0x49 0x4E (4C 49 4E = ASCII
“LIN”) as confirmation of the activation of this function. The terminal is then ready for receiving frames on the
LIN bus containing the 13-bit “sync break” and the “sync field” (0x55), and to make only the following
information in the receive data and to output these IDs during sending.

This setting is not permanently stored in the terminal and has to be written again after each new startup. The
startup [} 107] list can be used to circumvent this.

User-specific baud rate

Any already available baud rate and or the baud rate 10417 can be entered in the object “Explicit
baudrate” (0x8000:1B).

Further parameters

The following settings within CoE object 0x8000 [} 146] are necessary to ensure correct function in LIN
mode:

Index:Subindex Name Value

0x8000:01 Enable RTS/CTS FALSE
0x8000:02 Enable XON/XOFF supported tx FALSE
data
0x8000:03 Enable XON/XOFF supported rx FALSE
data
0x8000:04 Enable send FIFO data continuous FALSE
0x8000:05 Enable transfer rate optimization TRUE
0x8000:15 Dataframe 3 (8N1)
0x8000:1A Rx buffer full notification See objects for commissioning
[} 146].

Operation

The application of the control and status words remains unchanged in LIN mode.

In LIN mode, the EL6001 automatically precedes the user data with the “Break field” and the “Sync byte”
field. During receiving these two fields are automatically removed.

The process image should be used as follows:

EL6001 LIN example

The following LIN communication example is intended to illustrate that participation of a PLC controller via
the EL6001 terminal in a LIN cluster is possible by activating the complementary LIN functionality via the
0xB000 CoE “command” object in combination with a physical conversion of RS-232 to the LIN bus.

Hardware connection based on a UART-LIN converter

The implementation of the physical layer as a basic prerequisite for LIN communication includes the
provision of one-wire bus with corresponding signal levels 0V / 12V. This is best done with an RS232-LIN
converter, which is connected to a sub-D connector and on the other side provides three poles for ground,
power supply and the electrical connection to the one-wire LIN-bus.

The use of an RS232-LIN converter requires a sub-D 9-pin connector to be connected to the EL6001
terminal, as shown in the diagram:

Fig. 151: RS232-LIN sub-D connector connected to the EL6001 terminal

Electrical connections between the EL6001 terminal and the sub-D 9-pin connector:
• RxD →pin 2
• TxD →pin 3
• GND → pin 5

Programming in ST

A LIN communication can be represented by a PLC “master task”, whereby a master sends an
“unconditional frame”, as usual with a LIN bus, and only outputs the PID (protocol identifier) of a known slave
node on the LIN bus, thereby generally requesting data from the respective slave. The chapter on
commissioning contains a relevant programming example [} 136].

134 Version: 4.6 EL600x, EL602x

 Commissioning

In this example the slave has the ID 0x07; the master therefore sends the ID 0x07 on the bus, including the
calculated parity, resulting in the PID field 0x47. The message on the LIN bus then looks as follows:

Reading and interpreting time telegrams

This example shows a way to process and interpret the most diverse serial time protocols in the PLC. To this
end, IEC61131-PLC blocks will be presented that interpret the bit stream arriving at the PLC and, if
necessary, extract the time/place information. This information can be used, for example, to synchronize
controllers or record movements.

In this example, it is assumed that the data is delivered via a 22-byte interface by a Beckhoff EL/KL60xx
serial data exchange terminal.

Background information

Not only in maritime applications is time and place information transported via serial buses: In the majority of
cases an existing source distributes its information to lower level listeners/listeners cyclically or after a trigger
via RS232 / RS485, USB or Ethernet.
A very large number of telegram formats exists worldwide for the distribution of time and place information;
these are also known as ‘sentences’. Such a telegram consists of n bytes of data and is characterized by:
• Start and end characters STX, ETX for telegram recognition, possibly more than one end character
• a defined and fixed length
• a defined structure
• checksum (not necessary)
• type designations in the sentence if necessary

The most diverse organizations and companies have developed open or proprietary formats for specific
purposes of use. Therefore, two sample implementations will be presented in this example that can easily be
adapted to other specific protocols. The telegram formats in the example are the Meinberg Standard and
NMEA0183 v2.3 type RMC.

Sources of information

GPS or radio controlled clock gateways are used as data transmitters in the serial sector. These devices
receive the respective time signal (GPS via satellite or radio controlled clock via long wave) and convert it to
the serial, wire-bound transmission e.g. RS232 with 8N1. The gateway often contains a local clock source in
order to be able to continue distributing reliable time information for a certain time in the event of a short-term
failure of the reference signal (GPS, radio transmitter). In Central Europe, the German DCF77 transmitter
can be used.
If necessary, further information from the reference signal can be used:
• GPS: location information (W/N and height), upcoming clock change DCF77: weather information,
major incidents
• DCF77: weather information, major incidents

Synchronization of lower level time slaves

In general, lower level slaves should be adjusted to the time gateway, i.e. they should synchronize their time.
The following are necessary for this:
• Offset: the absolute deviation of the slave’s own clock from the gateway reference time – this
information can be transmitted, for example, acyclically and serially if it is known when the time
information is to be considered valid. Gaining these offset-information is possible via the serial
transport route from this example.
• the frequency ratio: a high-precision cyclic signal from the gateway to the slaves allows drift processes
to be compensated and might state the time when the above absolute offset is valid. One example of
such a signal is the widespread PPS (pulses per second).

If the serial telegram from the gateway is placed cyclically to the bus, the time of the first bit can often be
interpreted as a PPS signal. In the block in this example, this information would be lost; only the absolute
time information is evaluated.

Time formats

Time telegrams conforming to the NMEA0183 standard are widespread. Please note:
• there are currently (as of 2009) 8 versions of NMEA0183 1.5 to 4.00 within the NMEA0183 standard –
the structure of telegrams may have changed between the versions.
• 70 different formats are defined in NMEA0183 v2.30 alone; device manufacturers can create their own
formats in addition.
• The telegram is called a sentence
• A TalkerID (2 characters) and a TypeID (3 characters) at the start define the type of sentence used.
• A checksum is calculated for the telegram.
• Information can be found online at www.nmea.org or elsewhere.

Furthermore, many proprietary formats exist, such as Meinberg Standard, Siemens SINEC H1 and SAT
1703, or military formats, such as the IRIG codes (USA).

Using the sample program

The PLC project contains 2 function blocks (FBs), which must be linked exclusively with an EL/KL600x. Then
collect the received bytes from the terminal and interpret the contents as far as possible. The FBs cover:
• Meinberg Standard
• NMEA0183 v2.3 type RMC

For other time formats, you can create your own interpretation FBs on the basis of a known telegram
structure; contact your device manufacturer regarding this.

Hardware used in the example: EK1100 and EL6001 (also EL600x, KL600x)
The FB to be tested must be linked with its process data to the terminal in the System Manager (22-byte
process image and control/status word).
The NMEA block is linked in the example. The baud rate of the terminal must be set to match your
transmitter.

6.2 Control and status word

Control word

The control word (CW) is located in the output process image, and is transmitted from the controller to the
terminal.
Bit CW.15 CW.14 CW.13 CW.12 CW.11 CW.10 CW.9 CW.8 CW.7 CW.6 CW.5 CW.4 CW.3 CW.2 CW.1 CW.0
Name OL7 OL6 OL5 OL4 OL3 OL2 OL1 OL0 - OL2* OL1* OL0* SC IR RA TR

Bits CW.15 to CW.8 are only shown if the large process image is used.
If the small or medium process image is used, only bits CW.7 to CW.0 are shown as control bytes! The
number of output bytes available for transfer from the controller to the terminal is displayed by bits OL2* ...
OL0*.

Legend
Bit Name Description
CW.15 ... CW8 OL7 ... OL0 1dec... 22dec If the large process image is used: Number of output bytes available for

transfer from the controller to the terminal.
1 ... 4 If the small process image is used: Number of output bytes available for
transfer from the controller to the terminal.
CW.3 SC rise Continuous sending of data from the FIFO.
(SendContinuous)
The send buffer is filled (up to 128 bytes) by the controller. The buffer content
is sent with rising edge of bit SC. The terminal acknowledges the data trans-
fer to the controller through setting of bit SW.2. SW.2 is cancelled with CW.3.
CW.2 IR 1bin The controller requests terminal for initialization. The send and receive func-
(InitRequest) tions are blocked, the FIFO pointers are reset, and the interface is initialized
with the values of the responsible objects (baud rate 4073 [} 144], data frame
4074 [} 144], feature bits 4075 [} 145]). The terminal acknowledges comple-
tion of the initialization via bit SW.2 [} 166] (IA).
0bin The controller once again requests the terminal to prepare for serial data ex-
change.
CW.1 RA toggle The controller acknowledges receipt of data by changing the state of this bit.
(ReceiveAccepted) Only then new data can be transferred from the terminal to the controller.
CW.0 TR toggle Via a change of state of this bit the controller notifies the terminal that the
(TransmitRequest) DataOut bytes contain the number of bytes indicated via the OL bits. The ter-
minal acknowledges receipt of the data in the status byte via a change of
state of bit SW.0 [} 166] (TA). Only now new data can be transferred from the
controller to the terminal.

Parameterization
The terminal is parameterized via the CoE - Online tab [} 108] (with a double-click on the respective
object, see below).

Introduction

The CoE overview contains objects for different intended applications:

• Objects required for parameterization [} 168] during commissioning
• Objects for indicating internal settings [} 169] (may be fixed)
• Profile specific objects [} 181], which represent the status displays of the inputs and outputs.

The following section first describes the objects required for normal operation, followed by a complete
overview of missing objects.

8...15 Output length Number of output bytes available for transfer from the UINT8
controller to the terminal.

PDO Assignment

The terminal makes two input/output process images available for each channel. These differ only in the
representation of the control/status data.

In the case of bitwise representation, the data is made available as shown in the tables above. In the case of
word-wise representation, the first 16 bits of the process data are combined in one word.

The process data objects begin as standard with a control/status word. This PDO assignment is required in
order to use the ‘TwinCAT PLC Serial Communication’ library.

8.3 Firmware Update EL/ES/EM/EPxxxx

This section describes the device update for Beckhoff EtherCAT slaves from the EL/ES, EM, EK and EP
series. A firmware update should only be carried out after consultation with Beckhoff support.

Storage locations

An EtherCAT slave stores operating data in up to 3 locations:

• Depending on functionality and performance EtherCAT slaves have one or several local controllers for
processing I/O data. The corresponding program is the so-called firmware in *.efw format.
• In some EtherCAT slaves the EtherCAT communication may also be integrated in these controllers. In
this case the controller is usually a so-called FPGA chip with *.rbf firmware.
• In addition, each EtherCAT slave has a memory chip, a so-called ESI-EEPROM, for storing its own
device description (ESI: EtherCAT Slave Information). On power-up this description is loaded and the
EtherCAT communication is set up accordingly. The device description is available from the download
area of the Beckhoff website at (http://www.beckhoff.de). All ESI files are accessible there as zip files.

Customers can access the data via the EtherCAT fieldbus and its communication mechanisms. Acyclic
mailbox communication or register access to the ESC is used for updating or reading of these data.

The TwinCAT System Manager offers mechanisms for programming all 3 parts with new data, if the slave is
set up for this purpose. Generally the slave does not check whether the new data are suitable, i.e. it may no
longer be able to operate if the data are unsuitable.

Simplified update by bundle firmware

The update using so-called bundle firmware is more convenient: in this case the controller firmware and the
ESI description are combined in a *.efw file; during the update both the firmware and the ESI are changed in
the terminal. For this to happen it is necessary

EL600x, EL602x Version: 4.6 187

Appendix

• for the firmware to be in a packed format: recognizable by the file name, which also contains the
revision number, e.g. ELxxxx-xxxx_REV0016_SW01.efw
• for password=1 to be entered in the download dialog. If password=0 (default setting) only the firmware
update is carried out, without an ESI update.
• for the device to support this function. The function usually cannot be retrofitted; it is a component of
many new developments from year of manufacture 2016.

Following the update, its success should be verified

• ESI/Revision: e.g. by means of an online scan in TwinCAT ConfigMode/FreeRun – this is a convenient
way to determine the revision
• Firmware: e.g. by looking in the online CoE of the device

NOTE
Risk of damage to the device!
Note the following when downloading new device files

• Firmware downloads to an EtherCAT device must not be interrupted

• Flawless EtherCAT communication must be ensured. CRC errors or LostFrames must be avoided.
• The power supply must adequately dimensioned. The signal level must meet the specification.

In the event of malfunctions during the update process the EtherCAT device may become unusable and re-
quire re-commissioning by the manufacturer.

8.3.1 Device description ESI file/XML

NOTE
Attention regarding update of the ESI description/EEPROM
Some slaves have stored calibration and configuration data from the production in the EEPROM. These are
irretrievably overwritten during an update.

The ESI device description is stored locally on the slave and loaded on start-up. Each device description has
a unique identifier consisting of slave name (9 characters/digits) and a revision number (4 digits). Each slave
configured in the System Manager shows its identifier in the EtherCAT tab:

Fig. 164: Device identifier consisting of name EL3204-0000 and revision -0016

The configured identifier must be compatible with the actual device description used as hardware, i.e. the
description which the slave has loaded on start-up (in this case EL3204). Normally the configured revision
must be the same or lower than that actually present in the terminal network.

For further information on this, please refer to the EtherCAT system documentation.

188 Version: 4.6 EL600x, EL602x

 Appendix

Update of XML/ESI description

The device revision is closely linked to the firmware and hardware used. Incompatible combinations
lead to malfunctions or even final shutdown of the device. Corresponding updates should only be
carried out in consultation with Beckhoff support.

Display of ESI slave identifier

The simplest way to ascertain compliance of configured and actual device description is to scan the
EtherCAT boxes in TwinCAT mode Config/FreeRun:

Fig. 165: Scan the subordinate field by right-clicking on the EtherCAT device

If the found field matches the configured field, the display shows

Fig. 166: Configuration is identical

otherwise a change dialog appears for entering the actual data in the configuration.

EL600x, EL602x Version: 4.6 189

Appendix

Fig. 167: Change dialog

In this example in Fig. Change dialog, an EL3201-0000-0017 was found, while an EL3201-0000-0016 was
configured. In this case the configuration can be adapted with the Copy Before button. The Extended
Information checkbox must be set in order to display the revision.

Changing the ESI slave identifier

The ESI/EEPROM identifier can be updated as follows under TwinCAT:

• Trouble-free EtherCAT communication must be established with the slave.
• The state of the slave is irrelevant.
• Right-clicking on the slave in the online display opens the EEPROM Update dialog, Fig. EEPROM
Update

Fig. 168: EEPROM Update

The new ESI description is selected in the following dialog, see Fig. Selecting the new ESI. The checkbox
Show Hidden Devices also displays older, normally hidden versions of a slave.

190 Version: 4.6 EL600x, EL602x

 Appendix

Fig. 169: Selecting the new ESI

A progress bar in the System Manager shows the progress. Data are first written, then verified.

The change only takes effect after a restart.

Most EtherCAT devices read a modified ESI description immediately or after startup from the INIT.
Some communication settings such as distributed clocks are only read during power-on. The Ether-
CAT slave therefore has to be switched off briefly in order for the change to take effect.

8.3.2 Firmware explanation

Determining the firmware version

Determining the version on laser inscription

Beckhoff EtherCAT slaves feature serial numbers applied by laser. The serial number has the following
structure: KK YY FF HH

KK - week of production (CW, calendar week)

YY - year of production
FF - firmware version
HH - hardware version

Example with ser. no.: 12 10 03 02:

12 - week of production 12
10 - year of production 2010
03 - firmware version 03
02 - hardware version 02

Determining the version via the System Manager

The TwinCAT System Manager shows the version of the controller firmware if the master can access the
slave online. Click on the E-Bus Terminal whose controller firmware you want to check (in the example
terminal 2 (EL3204)) and select the tab CoE Online (CAN over EtherCAT).

CoE Online and Offline CoE

Two CoE directories are available:
• online: This is offered in the EtherCAT slave by the controller, if the EtherCAT slave supports this.
This CoE directory can only be displayed if a slave is connected and operational.
• offline: The EtherCAT Slave Information ESI/XML may contain the default content of the CoE.
This CoE directory can only be displayed if it is included in the ESI (e.g. "Beckhoff EL5xxx.xml").
The Advanced button must be used for switching between the two views.

In Fig. Display of EL3204 firmware version the firmware version of the selected EL3204 is shown as 03 in
CoE entry 0x100A.

EL600x, EL602x Version: 4.6 191

Appendix

Fig. 170: Display of EL3204 firmware version

In (A) TwinCAT 2.11 shows that the Online CoE directory is currently displayed. If this is not the case, the
Online directory can be loaded via the Online option in Advanced Settings (B) and double-clicking on
AllObjects.

8.3.3 Updating controller firmware *.efw

CoE directory
The Online CoE directory is managed by the controller and stored in a dedicated EEPROM, which
is generally not changed during a firmware update.

Switch to the Online tab to update the controller firmware of a slave, see Fig. Firmware Update.

Fig. 171: Firmware Update

192 Version: 4.6 EL600x, EL602x

 Appendix

Proceed as follows, unless instructed otherwise by Beckhoff support. Valid for TwinCAT 2 and 3 as
EtherCAT master.
• Switch TwinCAT system to ConfigMode/FreeRun with cycle time >= 1 ms (default in ConfigMode is 4
ms). A FW-Update during real time operation is not recommended.

• Switch EtherCAT Master to PreOP

• Switch slave to INIT (A)

• Switch slave to BOOTSTRAP
• Check the current status (B, C)
• Download the new *efw file (wait until it ends). A pass word will not be neccessary usually.

• After the download switch to INIT, then PreOP

• Switch off the slave briefly (don't pull under voltage!)
• Check within CoE 0x100A, if the FW status was correctly overtaken.

8.3.4 FPGA firmware *.rbf

If an FPGA chip deals with the EtherCAT communication an update may be accomplished via an *.rbf file.
• Controller firmware for processing I/O signals
• FPGA firmware for EtherCAT communication (only for terminals with FPGA)

EL600x, EL602x Version: 4.6 193

Appendix

The firmware version number included in the terminal serial number contains both firmware components. If
one of these firmware components is modified this version number is updated.

Determining the version via the System Manager

The TwinCAT System Manager indicates the FPGA firmware version. Click on the Ethernet card of your
EtherCAT strand (Device 2 in the example) and select the Online tab.

The Reg:0002 column indicates the firmware version of the individual EtherCAT devices in hexadecimal and
decimal representation.

Fig. 172: FPGA firmware version definition

If the column Reg:0002 is not displayed, right-click the table header and select Properties in the context
menu.

Fig. 173: Context menu Properties

The Advanced Settings dialog appears where the columns to be displayed can be selected. Under
Diagnosis/Online View select the '0002 ETxxxx Build' check box in order to activate the FPGA firmware
version display.

194 Version: 4.6 EL600x, EL602x

Fig. 174: Dialog Advanced Settings

Update

For updating the FPGA firmware

• of an EtherCAT coupler the coupler must have FPGA firmware version 11 or higher;
• of an E-Bus Terminal the terminal must have FPGA firmware version 10 or higher.

Older firmware versions can only be updated by the manufacturer!

Updating an EtherCAT device

The following sequence order have to be met if no other specifications are given (e.g. by the Beckhoff
support):
• Switch TwinCAT system to ConfigMode/FreeRun with cycle time >= 1 ms (default in ConfigMode is
4 ms). A FW-Update during real time operation is not recommended.

EL600x, EL602x Version: 4.6 195

Appendix

• In the TwinCAT System Manager select the terminal for which the FPGA firmware is to be updated (in
the example: Terminal 5: EL5001) and
click the Advanced Settings button in the EtherCAT tab:

• The Advanced Settings dialog appears. Under ESC Access/E²PROM/FPGA click on Write FPGA
button:

196 Version: 4.6 EL600x, EL602x

 Appendix

• Select the file (*.rbf) with the new FPGA firmware, and transfer it to the EtherCAT device:

• Wait until download ends

• Switch slave current less for a short time (don't pull under voltage!). In order to activate the new FPGA
firmware a restart (switching the power supply off and on again) of the EtherCAT device is required.
• Check the new FPGA status

NOTE
Risk of damage to the device!
A download of firmware to an EtherCAT device must not be interrupted in any case! If you interrupt this
process by switching off power supply or disconnecting the Ethernet link, the EtherCAT device can only be
recommissioned by the manufacturer!

8.3.5 Simultaneous updating of several EtherCAT devices

The firmware and ESI descriptions of several devices can be updated simultaneously, provided the devices
have the same firmware file/ESI.

Fig. 175: Multiple selection and firmware update

Select the required slaves and carry out the firmware update in BOOTSTRAP mode as described above.

EL600x, EL602x Version: 4.6 197

Appendix

8.4 Restoring the delivery state

To restore the delivery state for backup objects in ELxxxx terminals, the CoE object Restore default
parameters, SubIndex 001 can be selected in the TwinCAT System Manager (Config mode) (see Fig.
Selecting the Restore default parameters PDO)

Fig. 176: Selecting the "Restore default parameters" PDO

Double-click on SubIndex 001 to enter the Set Value dialog. Enter the value 1684107116 in field Dec or the
value 0x64616F6C in field Hex and confirm with OK (Fig. Entering a restore value in the Set Value dialog).
All backup objects are reset to the delivery state.

Fig. 177: Entering a restore value in the Set Value dialog

Alternative restore value

In some older terminals the backup objects can be switched with an alternative restore value: Deci-
mal value: 1819238756, Hexadecimal value: 0x6C6F6164An incorrect entry for the restore value
has no effect.
