Chapter 1 Introduction

1.2.1 Product Scope

Module Termination Units (MTU) and two types of I/O modules; S800 I/O and
S800L I/O modules.
S800 I/O modules are designed to be used together with a Module Termination
Unit.
S800L I/O modules are designed to be directly mounted on a standard DIN rail. The
module also contains terminals for connections.

1.2.1.1 Module Termination Units

The Module Termination Units (MTU) are passive base units used to house the I/O
modules. They contain the process wiring terminals and a section of the
ModuleBus.
The Module Termination Units (MTU) distributes the ModuleBus to the I/O module
and to the next MTU. It also generates the correct address to the I/O module by
shifting the outgoing position signals to the next MTU.
Two mechanical keys are used to configure the MTU for different types of I/O
modules. This is only a mechanical configuration and it does not affect the
functionality of the MTU or the I/O module. Each key has six positions, which gives
a total number of 36 different configurations. The configuration can be changed
with a screwdriver.
The MTU can be mounted on a standard DIN rail. It has a mechanical latch that
locks the MTU to the DIN rail. The latch can be released with a screwdriver.
The MTU has a mechanical locking mechanism that locks the module in its
position. This mechanism also gives the signal BLOCK to the I/O module that
keeps the module in its init state until it is locked in its position.
The top part of the MTU can be removed to replace the termination board even with
the system running. Such a need can be caused by a damaged terminal screw.

 Modules and Termination Units User’s Guide
Section 1.2.1 Product Scope

The MTUs are available in two versions (Compact and Extended). The Compact
MTU version typically provides for a compact installation of the I/O modules using
1 wire connections. The Extended MTU version provides for a more complete
installation on the MTU, including 3 wire connection, fuses and field circuit power
distribution. See Figure 1-2 and Figure 1-3 for an illustration of the MTUs together
with the I/O modules.
See Table 3-1 for information about the combination between MTU and I/O
modules and to specifications in Appendix A, Specifications for more information.

1.2.1.2 S800 I/O Modules

The I/O modules have open ventilated plastic enclosures. On the front of each I/O
module there are three LEDs (FAULT, RUN and WARNING) indicating the module
status and digital I/O modules have one or two status LED for each channel. One
additional LED (OSP) is included on analog output and digital output modules.
Refer to Section 5.2, Hardware Indicators for the status indication of the LEDs.
I/O modules may be replaced in a fully operational I/O station. Mechanical keying
on modules and MTUs protect I/O modules from being inserted in positions where
they could be damaged by excessive voltage or current. An electronic type
designation ID in each module keeps the I/O module from being taken into
operation by the FCI, if a module’s ID doesn’t match the configured module type
definition.

DP820 Incremental Pulse Counter Module

DP820 is an two-channel pulse counting module for incremental pulse transmitters
up to 1.5 MHz. Each channel contains counters and registers for position/length and
speed/frequency measurement. Each channel provides three balanced inputs for
connection of a pulse transmitter, one digital input and one digital output.
Pulse transmitters with RS422, +5 V, +12 V, +24 V and 13 mA interfaces can be
connected to DP820.

1.2.1.3 S800L I/O Modules

The I/O modules have open ventilated plastic enclosures and a bottom of sheet
metal. On the front of each I/O module there is one LED (STATUS) indicating the
module status and digital I/O modules have one status LED for each channel. Refer
to Section 5.2, Hardware Indicators for the status indication of the LEDs.
An electronic type designation ID in each module keeps the I/O module from being
taken into operation by the FCI, if a module’s ID doesn’t match the configured
module type definition.
Please refer to specifications in Appendix A, Specifications for more information.
The module can be mounted on a standard DIN rail. The module is locked to the
DIN rail by using the locking screw.
The I/O module distributes the ModuleBus to the next module. It also generate the
correct address to the next module by shifting the outgoing position signals.

5.4.1 S800 I/O Module Replacement

General
All I/O modules can be exchanged on-line and with the process power supply
connected, except for relay outputs with normally closed contacts. This is possible
because the module deactivates when the I/O module lock switch is turned to
unlock.
It is important to understand the consequences of a module exchange on-line and
how it affects the process. Replacement of an S800 I/O module affects all channels
on the module. It also sometimes indirectly affects the outputs via some application
function, on another module.
The system software in the FCI checks automatically that all I/O modules function
correctly. In the event of module fault, and module exchange, the module and
associated signals are marked as faulty.
The system software checks that the module is inserted and correct. If this is the
case, the Fault-indicator (LED) extinguishes and RUN LED is activated and the
module resumes its normal function.
The following headings include general instructions for replacement of modules and
aspects on the handling of individual modules are presented in Table 5-5.

5.4.2 S800L I/O Module Replacement

General
I/O modules can not be exchanged on-line. The power must be switched off to the
I/O station and the module before exchanging the I/O module.
It is important to understand the consequences of a power switch off to an I/O
station and how it affects the process. A power switch off to an I/O station affects all
modules and channels in the station. It also sometimes indirectly affects outputs in
other I/O stations via some application functions.
The system software checks that the module is inserted and correct. If this is the
case, the Fault indication extinguishes and after configuration and enter operation
mode the Run indication is activated and the module resumes its normal function.

or 2...10 V d.c., single ended unipolar inputs F
R
• 1 group of 8 channels isolated from ground W

• 12 Bit resolution

Description
The AI810 Analog Input Module has 8 channels. Each channel can be 7
either a voltage or current input.
8
The current input is able to handle a short circuit to the transmitter
supply at least 30 V d.c without damage. Current limiting is performed AI810
0..20 mA, 0..10 V
with a PTC resistor. The input resistance of the current input is
250 ohm, PTC included.
The voltage input is able to withstand an over or undervoltage of at
least 30 V d.c. Input resistance is 290k ohm. The EMC protection is
placed on the module.
Transmitter supply can be connected to L1+, L1- and/or L2+, L2-.
The module distributes the external transmitter supply to each channel. This adds a simple
connection to distribute the supply to 2- or 3-wire transmitters. There are no current limiting on the
transmitter power terminals. Fused MTUs TU830, TU835 and TU838 provides groupwise and
channelwise fusing.
All eight channels are isolated from the ModuleBus in one group. Power to the input stages is
converted from the 24 V on the ModuleBus.

Three LEDs indicate module status Fault (Red), Run (Green) and Warning (Yellow). The RUN LED
indicates normal operation and the WARNING LED indicates if any error input is active.
The FAULT LED indicates that the module is in Init state or Not configured state. In Not configured
state the FAULT LED is turned off after the first valid access to the module.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
Five different types of MTUs can be used. The TU830 Extended MTU enables three wire
connection to the devices without additional terminals. The TU810 (or TU814) Compact MTU has
terminals for 24 V process voltage inputs, but requires external terminals for distribution of 24 V
power supply to the field devices. The extended MTU, TU835, and TU838 provides a fuse
(3 A max.) per channel for process power out. The TU812 Compact MTU has a D-Sub 25 pin (male)
connector for connection to the process.

Description 4

The AI820 Analog Input Module has 4 differential, bipolar

current/voltage inputs. Each channel can be either a voltage or current
input.
AI820
The current inputs can withstand an accidental maximum normal mode ±20 mA, ±10 V Diff

30 V d.c. connection. To protect the current input circuit against

dangerous input levels, that is, by accidentally connecting a 24 V
source, the resistor rating of the 250Ω current sense resistors is about
5 Watts. This is intended only to temporarily protect one channel at a
time.
The module distributes the external transmitter supply to each channel. This adds a simple
connection (with extended MTUs) to distribute the supply to external 2 wire transmitters. There is
no current limiting on the transmitter power terminals.
All 4 channels are isolated from the ModuleBus in one group. Power to the input stages is converted
from the 24 V on the ModuleBus.

Three LEDs indicate module status Fault (Red), Run (Green) and Warning (Yellow). The RUN LED
indicates normal operation and the WARNING LED indicates if any diagnostic condition is active.
The FAULT LED indicates that the module is in Init state or Not configured state. In Not Configured
state the FAULT LED is turned off after the first valid access to the module.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
Four different types of MTUs can be used. The TU830 Extended MTU enables three wire

inputs F
R
• 3-wire connection to RTDs W

• 14 Bit resolution

Description 5

The AI830 RTD Input Module has 8 channels for measurement of 6

temperature with resistive elements (RTDs). With 3-wire connections.
All the RTDs must be isolated from ground. 7

The AI830 can be used with Pt100, Cu10, Ni100, Ni120 or resistive 8
sensors. Linearization and conversion of the temperature to Centigrade
or Fahrenheit is performed on the module. Every channel can be AI830
RTD
individually configured.
The diagnostic is updated in a cyclic manner and can be read any time.
Diagnostics include: open circuit, short circuit, error in reference channels, signal over range, signal
under range and power supply low.
The MainsFreq parameter is used to set mains frequency filter cycle time. This will give a notch
filter at the frequency specified (50 Hz or 60 Hz).
Three LEDs indicate module status Fault (Red), Run (Green) and Warning (Yellow). The RUN LED
indicates normal operation and the WARNING LED indicates if any error input is active.
The FAULT LED indicates that the module is in Init state, Error state or Not configured state.
In Not configured state the FAULT LED is turned off after the first valid access to the module.

The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
Four different types of MTUs can be used. The TU830 Extended MTU and the TU810 (or TU814)
Compact MTU enables three wire connection to the devices without additional terminals.
The TU812 Compact MTU has a D-Sub 25 pin (male) connector for connection to the process.

A.5 AI835 Thermocouple/mV Input Module

Features
• 8 differential input channels for thermocouple/mV
F
• Channel 8 can be designated as the CJ-channel R
(4-wire Pt100 RTD) W

• Variety of thermocouples with the following characteristics:

1
B, C, E, J, K, N, R, S an T
• 15 Bit resolution (A/D) 2

• Inputs are monitored for wire-break open-circuit 3

• EMC protection
4
• DIN rail mounting.
5

Description 6

The AI835 Thermocouple/mV Input Module is part of the S800 I/O.

7
It provides 8 differential input channels for Thermocouple/mV
measurements. Measurement ranges configurable per channel are: 8
-30 mV to +75 mV linear, or TC Types B, C, E, J, K, N, R, S an T.
AI835
One of the channels (Channel 8) may be configured for “Cold TC/mV
Junction” (ambient) temperature measurements, thus serving as
CJ-channel for Ch. 1...7. The junction temperature may be measured
locally on the MTUs screw terminals, or on a connection unit distant form the device. Alternatively,
a fix junction temperature for the module may be set by the user (as parameter). Channel 8 may be
used in the same manner as Ch. 1...7 when no CJ-temperature measurement is needed.
Each input-channel can measure a mV type of signal source (Thermocouple or linear), and may be
grounded or ungrounded.
Full self-calibration is obtained by means of 0V, 50 mV and 100 ohm references, which are regularly
updated.
Three LEDs indicate module status Fault (Red), Run (Green) and Warning (Yellow). The RUN LED
indicates normal operation and the WARNING LED indicates if any error input is active.

 Modules and Termination Units User’s Guide
Section A.5 AI835 Thermocouple/mV Input Module

The FAULT LED indicates that the module is in Init state, Error state or Not configured state.
In Not configured state the FAULT LED is turned off after the first valid access to the module.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
Four different types of MTUs can be used. The TU830 Extended MTU or the TU810 (or TU814)

One LED are used to indicate the state of the O - O - O - O - O - O - O - O -
module.The STATUS LED green indicates that the
device is in operational state. The STATUS LED
red indicates that the device is in error state.
In Not configured state the STATUS LED is turned
off after the first valid access to the module.
The module performs self-diagnostic cyclically.
Module diagnostics include: Internal power supply
supervision which is reported when supply voltage is to low.

Section A.6 AO801 Analog Output Module, 0...20 mA

The outputs of the module will be set to a predetermined value if the OSP-watchdog timer expires or
if the SetOSPState command is received. The watchdog timer is set by the controller (OSP timer)
and is used for ModuleBus supervision. The watchdog timer is re-triggered every time the correct
module address has been decoded (or broadcast). If the watchdog timer expires or if the
SetOSPState command is received, the module enters the OSP state and the active outputs (if any)
are set to their OSP values which can be configured as a predefined value or to use the last good
value sent.The output values will be kept as long as the module stays in the OSP state. To change the
outputs the module first has to leave this state. When reentering Operational State, the outputs are
still kept with their OSP value until new valid values are written.
The reset circuitry gives a reset signal when the POWOK signal is active. The POWOK comes from
the FCI after power is applied.

Power Dissipation Calculation

If output load <250 ohms and high power supply can max. power dissipation be exceeded.
The total power dissipated in the output stages should be <1.2 W. Can be calculated according to:
UP <24 V
8
Poutput = ∑ [( UP - 4.7 - ( RLi + 100 ) x ICHi ) x ICHi ]
i=1
UP >24 V
8
Poutput = ∑ [( 19.3 - ( RLi + 100 ) x ICHi ) x ICHi ]
i=1
UP = Power supply to the output stages
ICHi = Average output current per channel
RLi = Output load per channel
Temporary overload or short circuit does not cause any damage but long term overload will decrease
module MTBF.

Description
4
The AO810 Analog Output Module has 8 unipolar analog output
channels. 5
To supervise the communication to the D/A-converters the serial data is
6
read back and verified. The open-circuit diagnostic is received during
the readback. 7
Four LEDs are used to indicate the state of the device. The RUN
8
(green) LED indicates that the device is in operational state.
The FAULT (red) LED indicates that the device is in error state.
In Not configured state the FAULT LED is turned off after the first AO810
valid access to the module. The WARNING (yellow) LED indicates 0..20 mA

that there is some kind of process error such as an open circuit, or

power supply fault. OSP (yellow) LED indicates that the output value
is set to the OSP value.
The module performs self-diagnostic cyclically. Module diagnostics include: Process power supply
supervision which is reported when supply voltage to output circuitry is to low. The error is reported
as a channel error. Channel diagnostic include: Fault detection of the channel. (Only reported on
active channels). The error is reported if the output current is less than the output set value.

The outputs of the module will be set to a predetermined value if the OSP-watchdog timer expires or
if the SetOSPState command is received. The watchdog timer is set by the controller (OSP timer)
and is used for ModuleBus supervision. The watchdog timer is re-triggered every time the correct

command is received, the module enters the OSP state and the active outputs (if any) are set to their
OSP values which can be configured as a predefined value or to use the last good value sent.
The output values will be kept as long as the module stays in the OSP state. To change the outputs
the module first has to leave this state. When reentering Operational State, the outputs are still kept
with their OSP value until new valid values are written.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
Four different types of MTUs can be used. The TU830 Extended MTU and the TU810 (or TU814)
Compact MTU enables wire connection to the devices without additional terminals. The TU812
Compact MTU has a D-Sub 25 pin (male) connector for connection to the process.

Description
The AO820 Analog Output Module has 4 bipolar analog output
3
channels. The choice of current or voltage output is configurable for
each channel. There are separate sets of terminals for voltage and
current outputs, and it is up to the user to wire outputs properly.
The only differences between current or voltage channel configuration 4
is in software settings.
To supervise the communication to the A/D-converters the output data
is read back and verified. The open-circuit diagnostics are read
AO820
continuously as well. ±20 mA, ±10V Isolated

Four LEDs are used to indicate the state of the device. The RUN
(green) LED indicates that the device is in operational state.
The FAULT (red) LED indicates that the device is in an error state, or a power fault has been
detected. In Not configured state the FAULT LED is turned off after the first valid access to the
module. The WARNING (yellow) LED indicates that there is some kind of process error such as an
open circuit. OSP (yellow) LED indicates that the output values are set to the OSP value.
The process voltage supervision input give channel error signals if the voltage disappears.The error
signal can be read via the ModuleBus. Channel diagnostics include: Fault detection of the channel.
(Only reported on active channels). The error is reported if the output current differ from the output
set value (that is, open wire condition).

3BSE 020 924R301 101

Modules and Termination Units User’s Guide
Appendix A Specifications

The outputs of the module will be set to a predetermined value if the OSP-watchdog timer expires or
if the SetOSPState command is received. The watchdog timer is set by the controller and is used for
ModuleBus supervision. The watchdog timer is re-triggered every time the correct node address has
been decoded (or broadcast). If the watchdog timer expires or if the SetOSPState command is
received, the module enters the OSP state and the active outputs (if any) are set to their OSP values
which can be configured as a predefined value or as the last good value sent.
The output values will be kept as long as the module stays in the OSP state. To change the outputs
the module first has to leave this state. When reentering Operational State, the outputs are still kept
with their OSP value until new valid values are written.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
Four different types of MTUs can be used. The TU830 Extended MTU and the TU810 (or TU814)
Compact MTU enables wire connection to the devices without additional terminals. The TU812
Compact MTU has a D-Sub 25 pin (male) connector for connection to the process.

Description 230V a.c./d.c.
The DI803 is an 8 channel 120 V a.c./d.c.digital
input module for the S800 I/O. This module has
8 digital inputs. The a.c. input voltage range is
164 - 264 volt and the input current is 11 mA at
230 V a.c. The d.c. input range is 175 - 275 V and
1 2 3 4 5 6 7 8
the input current is 1.6 mA at 220 V. The inputs are A B A B A B A B A B A B A B A B
individually isolated.
Every input channel consists of current limiting
components, EMC protection components, input
state indication LED and optical isolation barrier.
One STATUS LED red or green indicate module
status. One LED (Yellow) per channel (8) indicate input channel status (On = 1 and Off = 0). The
STATUS LED green indicates normal operation. The STATUS LED red indicates that the module is
in Init state or Not configured state. In Not Configured state the STATUS LED is turned off after the
first valid access to the module.

Channel 8 can be used as voltage supervision input for channels 1-7..

Section A.11 DI803 Digital Input Module, 230 V a.c./d.c, Current Sinking

If the voltage connected to channel 8 disappears, the error inputs are activated and the Warning LED
turns on. The error signal can be read from the ModuleBus. This supervision can be
enabled/disabled with the “a” parameter. If the error inputs are disabled channel 8 can be used as
normal input channels.
The reset circuitry gives a reset signal when the POWOK signal is active.
The input channels can be digitally filtered. The different filter times that can be achieved are
2, 4, 8 and 16 ms. This means that noise pulses shorter than the filter time will be filtered out and
pulses longer than 3, 6, 12 and 24 ms will get through the filter.

The input channels can be digitally filtered. The different filter times that can be achieved are
2, 4, 8 and 16 ms. This means that noise pulses shorter than the filter time will be filtered out and
pulses longer than 3, 6, 12 and 24 ms will get through the filter.
Five different types of MTUs can be used. The TU830 Extended MTU enables three wire
connection to the devices without additional terminals. The TU810 (or TU814) Compact MTU has
terminals for 24 V process voltage supervision inputs, but requires external terminals for
distribution of 24 V power supply to the devices. The extended MTU, TU838, provides a fuse
(3 A max.) per two channels for process power out. The TU812 Compact MTU has a D-Sub 25 pin
(male) connector for connection to the process.

The DI811 is a 16 channel 48 V digital input module for the S800 I/O.
8
This module has 16 digital inputs. The input signal voltage range is 9
36 to 60 volt d.c. and the input current is 4 mA at 48 V. The inputs are 10
divided into two individually isolated groups with eight channels and 11
one voltage supervision input in each group. 12
13
Every input channel consists of current limiting components, EMC 14
protection components, input state indication LED and optical 15
isolation barrier. 16

Three LEDs indicate module status Fault (Red), Run (Green) and
Warning (Yellow). One LED (Yellow) per channel (16) indicate input
state (On = 1 and Off = 0). The RUN LED indicates normal operation
and the WARNING LED indicates if any error input is active.
The FAULT LED indicates that the module is in Init state or Not
configured state. In Not Configured state the FAULT LED is turned off after the first valid access to
the module.
The process voltage supervision input give channel error signals if the voltage disappears.The error
signal can be read via the ModuleBus.
The process voltage supervision input give channel error signals if the voltage disappears.The error

inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
The input channels can be digitally filtered. The different filter times that can be achieved are
2, 4, 8 and 16 ms. This means that noise pulses shorter than the filter time will be filtered out and
pulses longer than 3, 6, 12 and 24 ms will get through the filter.
Five different types of MTUs can be used. The TU830 Extended MTU enables three wire
connection to the devices without additional terminals. The TU810 (or TU814) Compact MTU has
terminals for 48 V process voltage supervision inputs, but requires external terminals for
distribution of 48 V power supply to the devices. The extended MTU, TU838, provide a fuse

• 2 Isolated groups of 8 with voltage supervision R
W
• Input status indicators
• EMC protection 1

Description 5
6
The DI814 is a 16 channel 24 V digital input module with current 7
sourcing for the S800 I/O. The input voltage range is 18 to 30 volt dc 8
and the input current source is 6 mA at 24 V. The inputs are divided 9
into two individually isolated groups with eight channels and one 10
voltage supervision input in each group. 11
12
Every input channel consists of current limiting components, EMC 13
protection components, input state indication LED and optical 14
15
isolation barrier. 16
Three LEDs indicate module status Fault (Red), Run (Green) and
Warning (Yellow). One LED (Yellow) per channel (16) indicate input
state (On = 1 and Off = 0). The RUN LED indicates normal operation
and the WARNING LED indicates if any error input is active.
The FAULT LED indicates that the module is in Init state or Not
configured state. In Not Configured state the FAULT LED is turned off
after the first valid access to the module.
The process voltage supervision input give channel error signals if the voltage disappears.The error
signal can be read via the ModuleBus.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.

 Modules and Termination Units User’s Guide
Section A.14 DI814 Digital Input Module, 24 V , Current Sourcing

The input channels can be digitally filtered. The different filter times that can be achieved are
2, 4, 8 and 16 ms. This means that noise pulses shorter than the filter time will be filtered out and
pulses longer than 3, 6, 12 and 24 ms will get through the filter.
Five different types of MTUs can be used. The TU830 Extended MTU enables three wire
connection to the devices without additional terminals. The TU810 (or TU814) Compact MTU has
terminals for 24 V process voltage supervision inputs, but requires external terminals for
distribution of 24 V power supply to the devices. The extended MTU, TU838, provide a fuse
(3 A max.) per two channels for process power out. The TU812 Compact MTU has a D-Sub 25 pin
(male) connector for connection to the process.

Description
5
The DI820 is an 8 channel 120 V a.c./d.c. digital input module for the
S800 I/O. This module has 8 digital inputs. The a.c. input voltage 6
range is 77 - 130 volt and the input current is 10 mA at 120 V a.c.
7
The d.c. input range is 75 - 145 V and the input current is 2.8 mA at
110 V. The inputs are individually isolated. 8

Every input channel consists of current limiting components, EMC

protection components, input state indication LED, optical isolation DI820
barrier and an analog filter (6 ms). 120V a.c.

Three LEDs indicate module status Fault (Red), Run (Green) and
Warning (Yellow). One LED (Yellow) per channel (8) indicate input
state (On = 1 and Off = 0). The RUN LED indicates normal operation
and the WARNING LED indicates if any error input is active. The FAULT LED indicates that the
module is in Init state or Not configured state. In Not Configured state the FAULT LED is turned off
after the first valid access to the module.
Channel 1 can be used as voltage supervision input for channels 2 - 4, and channel 8 can be used as
voltage supervision input for channels 5 - 7.

Section A.15 DI820 Digital Input Module, 120 V a.c./d.c

If the voltage connected to channel 1 or 8 disappears, the error inputs are activated and the Warning
LED turns on. The error signal can be read from the ModuleBus. This supervision can be enabled/
disabled with a parameter. If the error inputs are disabled channel 1 and 8 can be used as normal
input channels.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
The input channels can be digitally filtered. The different filter times that can be achieved are
2, 4, 8 and 16 ms. This means that noise pulses shorter than the filter time will be filtered out and
pulses longer than 3, 6, 12 and 24 ms will get through the filter.
Two different types of MTUs can be used, TU831 Extended MTU and TU811 Compact MTU both
have two terminals per channel.

Description
9
The DI830 is a 16 channel 24 V d.c. digital input module for the 10
S800 I/O. The input voltage range is 18 to 30 V d.c. and the input 11
12
current is 6 mA at 24 V d.c.
13
Each input channel consists of current limiting components, EMC 14
15
protection components, input state indication LED and optical
16
isolation barrier.
DI830
Three LEDs indicate module status Fault (Red), Run (Green) and 24V, SOE
Warning (Yellow). One LED (Yellow) per channel (16) indicate input
state (On = 1 and Off = 0). The RUN LED indicates normal operation
and the WARNING LED indicates if any error input is active. The FAULT LED indicates that the
module is in the Init state, Error state or Not Configured state. In Not Configured state the FAULT
LED is turned off after the first valid master frame to the module.
The module cyclically performs self-diagnostics. Module diagnostics include:
• Process power supply supervision (causes a module failure if detected)
• Event queue full
• Time synchronization missing

Section A.17 DI830 Digital Input Module, 24 V d.c. with SOE, Current Sinking

The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
The input signals can be digitally filtered. The filter is selectable from 0 to 100 ms. This means that
pulses shorter than the filter time will be filtered out and pulses longer than specified will get
through the filter.
Five different types of MTUs can be used. The Extended MTU (for example TU830) enables three
wire connection to the transducers without additional terminals. The Compact MTU (for example
TU810 or TU 814) has terminals for process voltage supervision inputs, but requires external
terminals for distribution of process power supply to the transducers. The extended MTU, TU838,
provide a fuse (3 A max.) per two channels for process power out. The TU812 Compact MTU has a
D-Sub 25 pin (male) connector for connection to the process.

Modes

Event Recording
The DI830 Input Module can be used for event recording (SOE), that is, changing signals at digital
input channels can be announced together with a time stamp indicating when it occurred. The time
stamp has a resolution of 0.4 millisecond, and is compensated for the filter time.
The module has intermediate storage for 32 events.
The SOE functionality can be switched on and off per channel.
For all channels with enabled SOE capability, a shutter filter is implemented that prevents
intermediate storage for events from overflow. The shutter filter is closed as soon as the number of
events generated within the shutter period (0-255 seconds) exceeds the shutter trigger number
(0-255 changes). The shutter filter remains closed as long as the recovery time (0-65535 seconds)
has not expired.

Simple Digital Input

If no event recording is used, the DI830 acts like a simple digital input device.

Description 9
10
The DI831 is a 16 channel 48 V d.c. digital input module for the 11
S800 I/O. The input voltage range is 36 to 60 V d.c. and the input 12
current is 4 mA at 48 V d.c.). 13
14
Each input channel consists of current limiting components, EMC 15
protection components, input state indication LED and optical 16
isolation barrier.
DI831
Three LEDs indicate module status Fault (Red), Run (Green) and 48V, SOE

Warning (Yellow). One LED (Yellow) per channel (16) indicate input
state (On = 1 and Off = 0). The RUN LED indicates normal operation
and the WARNING LED indicates if any error input is active. The FAULT LED indicates that the
module is in the Init state, Error state or Not Configured state. In Not Configured state the FAULT
LED is turned off after the first valid master frame to the module.
The module cyclically performs self-diagnostics. Module diagnostics include:
• Process power supply supervision (causes a module failure if detected)
• Event queue full
• Time synchronization missing

3BSE 020 924R301 183

Modules and Termination Units User’s Guide
Appendix A Specifications

The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
The input signals can be digitally filtered. The filter is selectable from 0 to 100 ms. This means that
pulses shorter than the filter time will be filtered out and pulses longer than specified will get
through the filter.
Five different types of MTUs can be used. The Extended MTU (for example TU830) enables three
wire connection to the transducers without additional terminals. The Compact MTU (for example
TU810 or TU 814) has terminals for process voltage supervision inputs, but requires external
terminals for distribution of process power supply to the transducers. The extended MTU, TU838,
provide a fuse (3 A max.) per two channels for process power out. The TU812 Compact MTU has a
D-Sub 25 pin (male) connector for connection to the process.

Modes

Event Recording
The DI831 Input Module can be used for event recording (SOE), that is, changing signals at digital
input channels can be announced together with a time stamp indicating when it occurred. The time
stamp has a resolution of 0.4 millisecond, and is compensated for the filter time.
The module has intermediate storage for 32 events.
The SOE functionality can be switched on and off per channel.
For all channels with enabled SOE capability, a shutter filter is implemented that prevents
intermediate storage for events from overflow. The shutter filter is closed as soon as the number of
events generated within the shutter period (0-255 seconds) exceeds the shutter trigger number
(0-255 changes). The shutter filter remains closed as long as the recovery time (0-65535 seconds)
has not expired.

Simple Digital Input

If no event recording is used, the DI831 acts like a simple digital input device.

Section A.19 DI885 Digital Input Module, 24 V /48 V d.c. with SOE, Current Sink

The sensor power supply supervision gives an error signal if the voltage disappears, and the Warning
LED turns on. The error signal can be read via the Modulebus.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
The input signals of the input module DI885 can be filtered to suppress any electrical interference or
contact bounce.The filter is selectable from 0 to 255 ms. This means that noise pulses shorter than
the filter time will be filtered out and pulses longer than specified will get through the filter.
Four different types of MTUs can be used. TheTU830 Extended MTU and the TU810 (or TU814)
Compact MTU has terminals for process voltage inputs and three terminals per channel. The TU812
Compact MTU has a D-Sub 25 pin (male) connector for connection to the process.

Modes

Event Recording
The DI885 Input Module can be used for event recording (SOE), that is, changing signals at digital
input channels can be announced together with a time stamp indicating when it occurred. The time
stamp has a resolution of 1 millisecond, and is compensated for the filter time.
The module has intermediate storage for 32 events.
The SOE functionality can be switched on and off per channel.
For all channels with enabled SOE capability, a shutter filter is implemented that prevents
intermediate storage for events from overflow. The shutter filter is closed as soon as the number of
events generated within the shutter period (0-255 seconds) exceeds the shutter trigger number
(0-255 changes). The shutter filter remains closed as long as the recovery time (0-65535 seconds)
has not expired.

Simple Digital Input

If no event recording is used, the DI885 acts like a simple digital input device.

Channel Supervision
The DI885 is able to supervise the process channel regarding wire break of sensor cable, missing
sensor and short circuit of sensor voltage to module ground.

3BSE 020 924R301 195

Modules and Termination Units User’s Guide
Appendix A Specifications

The supervision can be switched on and off per device. The channel supervision is only possible
when the contact is equipped with a parallel resistor of 4.75 kΩ ±20%, and 48 V sensor power.

Sensor Power Supply and Supervision

The DI885 provides a 48 V d.c. sensor power supply per device.
The DC/DC - converter for 48 V d.c. supply can be powered from the internal 24 V d.c. provided
by the ModuleBus or from an external source.
The power supply is short-circuit proof and galvanically insulated.
It is also possible to supply the sensors with an external 48 V d.c. power supply. In this case the
internal voltage path is switched off.

Supported Sensor Types

The following sensor types are supported by the DI885.

Dry Contacts supervised: 48 V d.c./ 3,2 mA

The supervision is only possible for contacts with resistor connected in parallel. Supervision is
always available within internal sensor power supply. Supervision in connection with external
sensor power supply requires the same strict limits in the tolerances of the external supply voltage as
for internal supply voltage (48 V d.c. ±10%)

Dry Contacts not supervised with external Power Supply: >= 60 V d.c./ max. 4 mA
The maximum input voltage of 60 V DC must be kept strictly.

Electronic Inputs not supervised: 24 V d.c./ 1.6 mA

Only in combination with external power supply.

Open Collector Drivers (Current sourcing) not supervised: 24 V DC / 1.6 mA

Only in combination with external power supply.

Description
The DO801 is a 16 channel 24 V digital output
module for the S800 I/O. The output voltage L+ L- 24V
range is 10 to 30 volt and the maximum
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
continuous output current is 0.5 A. The outputs
are protected against short circuits, over voltage
and over temperature. The outputs are in one
isolated group.
Each output channel consists of a short circuit and
over temperature protected high side driver, EMC
protection components, inductive load suppression, output state indication LED and optical isolation
barrier.
One STATUS LED indicate module status green/red. One LED (Yellow) per channel (16) indicate
output state (On = 1 and Off = 0). The Status LED green indicates normal operation. The STATUS
LED red indicates that the module is in Init state or Not Configured state. In Not Configured state
the STATUS LED is turned off after the first valid access to the module.

3BSE 020 924R301 203

Modules and Termination Units User’s Guide
Appendix A Specifications

The outputs of the module will be set to a predetermined value if the OSP-watchdog timer expires or
if the SetOSPState command is received. The watchdog timer is set by the controller and is used for
ModuleBus supervision. The watchdog timer is re-triggered every time the correct module address
has been decoded (or broadcast). If the watchdog timer expires or if the SetOSPState command is
received, the module enters the OSP state and the active outputs (if any) are set to their OSP values
which can be configured as a predefined value or to use the last good value sent.
The output values will be kept as long as the module stays in the OSP state. To change the outputs
the module first has to leave this state. When reentering Operational State, the outputs are still kept
with their OSP value until new valid values are written.
The reset circuitry gives a reset signal when the POWOK signal is active. The POWOK comes from
the FCI after power is applied.
The outputs are current limited and protected against over temperature. If the outputs are overloaded
the output current will be limited. This means that the power dissipation in the output stage will
increase and the output will shutdown if the temperature in the output stage increases above 150 °C
(302 °F). The output will switch on again automatically as the component temperature has decreased
to about 140 °C (284 °F). If any output is shutdown due to overload the indication LED on that
channel is not switched off. The output status of that channel can not be read from the module.

Description 11
12
The DO810 is a 16 channel 24 V digital output module for the S800 13
I/O. This module has 16 digital outputs. The output voltage range is 14
10 to 30 volt and the maximum continuous output current is 0.5 A. 15
The outputs are protected against short circuits, over voltage and over 16
temperature. The outputs are divided into two individually isolated
DO810
groups with eight output channels and one voltage supervision input in 24V 0.5A
each group.
Each output channel consists of a short circuit and over temperature
protected high side driver, EMC protection components, inductive load
suppression, output state indication LED and optical isolation barrier.
Four LEDs indicate module status Fault (Red), Run (Green), Warning (Yellow) and OSP (Yellow).
One LED (Yellow) per channel (16) indicate output state (On = 1 and Off = 0). The RUN LED
indicates normal operation and the WARNING LED indicates if any error input is active.
The FAULT LED indicates that the module is in Init state or Not Configured state. In Not
Configured state the FAULT LED is turned off after the first valid access to the module. The OSP
LED indicates that the module is in the OSP state and that the outputs are set to their OSP values.
The process voltage supervision input give channel error signals if the voltage disappears.The error
signal can be read via the ModuleBus.

The outputs of the module will be set to a predetermined value if the OSP-watchdog timer expires or
if the SetOSPState command is received. The watchdog timer is set by the controller and is used for
ModuleBus supervision. The watchdog timer is re-triggered every time the correct module address
has been decoded (or broadcast). If the watchdog timer expires or if the SetOSPState command is
received, the module enters the OSP state and the active outputs (if any) are set to their OSP values
which can be configured as a predefined value or to use the last good value sent.
The output values will be kept as long as the module stays in the OSP state. To change the outputs
the module first has to leave this state. When reentering Operational State, the outputs are still kept
with their OSP value until new valid values are written.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
The outputs are current limited and protected against over temperature. If the outputs are overloaded
the output current will be limited. This means that the power dissipation in the output stage will
increase and the output will shutdown if the temperature in the output stage increases above 150 °C
(302 °F). The output will switch on again automatically as the component temperature has decreased
to about 140 °C (284 °F). If any output is shutdown due to overload the indication LED on that
channel is also switched off. The output status of that channel can not be read from the module.
Four different types of MTUs can be used. TU830 Extended MTU and TU810 (or TU814) Compact
MTU have terminals for 24 V process voltage supervision inputs and two terminals per channels.
The TU812 Compact MTU has a D-Sub 25 pin (male) connector for connection to the process.

Description 11
12
The DO814 is a 16 channel 24 V digital output module with current 13
sinking for the S800 I/O. The output voltage range is 10 to 30 volt and 14
the maximum continuous current sinking is 0.5 A. The outputs are 15
protected against short circuits and over temperature. The outputs are 16
divided into two individually isolated groups with eight output
DO814
channels and one voltage supervision input in each group. 24V, 0.5A

Each output channel consists of a short circuit and over temperature

protected low side switch, EMC protection components, inductive load
suppression, output state indication LED and optical isolation barrier.
Four LEDs indicate module status Fault (Red), Run (Green), Warning (Yellow) and OSP (Yellow).
One LED (Yellow) per channel (16) indicate output state (On = 1 and Off = 0). The RUN LED
indicates normal operation and the WARNING LED indicates if any error input is active.
The FAULT LED indicates that the module is in Init state or Not Configured state. In Not configured
state the FAULT LED is turned off after the first valid access to the module. The OSP LED indicates
that the module is in the OSP state and that the outputs are set to their OSP values.
The process voltage supervision input give channel error signals if the voltage disappears.The error
signal can be read via the ModuleBus.

224 3BSE 020 924R301

 Modules and Termination Units User’s Guide
Section A.23 DO814 Digital Output Module 24 V , 0.5 A, Current Sinking

The outputs of the module will be set to a predetermined value if the OSP-watchdog timer expires or
if the SetOSPState command is received. The watchdog timer is set by the controller and is used for
ModuleBus supervision. The watchdog timer is re-triggered every time the correct module address
has been decoded (or broadcast). If the watchdog timer expires or if the SetOSPState command is
received, the module enters the OSP state and the active outputs (if any) are set to their OSP values
which can be configured as a predefined value or to use the last good value sent.
The output values will be kept as long as the module stays in the OSP state. To change the outputs
the module first has to leave this state. When reentering Operational State, the outputs are still kept
with their OSP value until new valid values are written.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK is inactive and
POWOK signals is active. The BLOCK signal is deactivated when the module lock mechanism is in
the locked position. The POWOK comes from the FCI after power is applied.
The outputs are current limited and protected against over temperature. If the outputs are overloaded
the output current sinking will be limited. This means that the power dissipation in the output stage
will increase and the output will shutdown if the temperature in the output stage increases above
150 °C (302 °F). The output will switch on again automatically as the component temperature has
decreased to about 140 °C (284 °F).
Five different types of MTUs can be used. The TU830 Extended MTU enables three wire
connection to the devices without additional terminals. The TU810 (or TU814) Compact MTU has
terminals for 24 V process voltage supervision inputs, but requires external terminals for
distribution of 24 V power supply to the devices. The TU812 Compact MTU has a D-Sub 25 pin
(male) connector for connection to the process. TU838 provide a fuse (3 A max.) per two channels
or process power output.

DO815
24V, 2A
Description
The DO815 is a 8 channel 24 V digital output module for the S800 I/O.
The output voltage range is 10 to 30 volt and the maximum continuous output current is
2 A @ 24 V. The outputs are protected against short circuits, and over load. The outputs are divided
into two individually isolated groups with four output channels in each group.
Each output channel consists of a short circuit and over load protected high side driver with open
load detection, EMC protection components, inductive load suppression, output status indication
LEDs and optical isolation barrier.

Four LEDs indicate module status; Fault (Red), Run (Green), Warning (Yellow) and OSP (Yellow).
One LED (Yellow) per channel (8) indicate output state (On = 1 and Off = 0). The output fault
diagnostic function, that is, short circuit, over load, under voltage and open load detection, activities
a channel wise Error input and Fault LED (1F - 8F) (Red). The error signal can be read via the
ModuleBus. The RUN LED indicates normal operation and the WARNING LED indicates if any
Error input is active.
The FAULT LED indicates that the module is in Init state or Not Configured state. In Not
Configured state the FAULT LED is turned off after the first valid access to the module. The OSP
LED indicates that the module is in the OSP state and that the outputs are set to their OSP values.
The driver outputs provide a “free-wheel diode” to demagnetize inductive loads. No external
demagnetization arrangement is required up to loads of 1J.
DO815 outputs are able to drive filament lamp loads up to 10W, but only in Automatic reset mode.
The outputs of the module will be set to a predetermined value if the OSP-watchdog timer expires or
if the SetOSPState command is received. The watchdog timer is set by the controller and is used for
ModuleBus supervision. The watchdog timer is re-triggered every time the correct module address
has been decoded (or broadcast). If the watchdog timer expires or if the SetOSPState command is
received, the module enters the OSP state and the active outputs (if any) are set to their OSP values
which can be configured as a predefined value or to use the last good value sent.
The output values will be kept as long as the module stays in the OSP state. To change the outputs
the module first has to leave OSP state. When reentering Operational State, the outputs are still kept
with their OSP value until new valid values are written.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
DO815 provides two protection operation modes. Each channel can be configured to operate in one
of the two modes.
1. Automatic reset mode (Default mode): The output is switched off for a time interval by
the driver’s over current protection. Operation is resumed when the output current is
below a reset value.
2. Fault latching mode (This mode in not applicable in all controllers): The output is
switched off by any of the faultconditions. The fault latch remains in fault condition
until reset by temporarily setting the automatic reset mode.

Section A.24 DO815 Digital Output Module 24 V , 2 A, Current Sourcing

The output drivers are current limited and protected against over load. If an output has a short circuit
to ground the output current will be limited and the driver will shutdown in order to minimize the
power dissipation. In the automatic reset mode the output will switch on again automatically after a
defined time interval. If the short circuit condition is still present, the output is turned of again,
otherwise the normal operation is resumed. In the fault latching mode the output remains off until
the fault condition is not valid and the reset of the fault latch is activated. If any output is shutdown
due to fault condition the indication LED (Yellow) on that channel remains on if the channel is
activated.The output status of the channel can be read from the module.
Three different types of MTUs can be used, TU830 Extended MTU and TU810 (or TU814)
Compact MTU have terminals for 24 V process voltage supervision inputs and two terminals per
channels.

The outputs of the module will be set to a predetermined value if the OSP-watchdog timer expires or
if the SetOSPState command is received. The watchdog timer which is set by the controller and is
used for ModuleBus supervision. The watchdog timer is re-triggered every time the correct node
address has been decoded (or broadcast). If the watchdog timer expires or if the SetOSPState
command is received, the module enters the OSP state and the active outputs (if any) are set to their
OSP values which can be configured as a predefined value or to use the last good value sent.
The output values will be kept as long as the module stays in the OSP state. To change the outputs
the module first has to leave this state. When reentering Operational State, the outputs are still kept
with their OSP value until new valid values are written.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
Four different types of MTUs can be used. The TU831 Extended MTU and TU811 Compact MTU
enables two wire connection to the devices without additional terminals. The extended MTU,
TU836, provides an individual fuse (3 A max.) per channel on the load outlet terminals.
The extended MTU, TU837 provides an individual fuse (3 A max.) per channel. Outputs can be
individually isolated or grouped by bridging. Signal return terminals are provided in two groups of
four terminals.

SY2
The DP820 module consists of two identical independent channels. DO2
Each channel can be used for independent pulse count (length/position) TP2
and frequency (speed) measurement. UL2

Transducer Connection
DP820
Each channel has four inputs (A, B, ST and DI) and one output (DO).
The input signals A and B are used as pulse inputs. The input signals
ST and DI is used for synchronizing, sampling and gated count
purposes.
The balanced inputs A, B and ST can be connected to pulse transducers with RS422, 5 V , 12 V ,
24 V and 13 mA signal levels if an extended MTU is used (TU830). Adaption to different signal
levels is made by using different terminals on the MTU (see chapter about process connection).
Only pulse transducers with RS422, 5 V and 13 mA signal levels can be used if an compact MTU is
used (TU810, TU812 or TU814).
The unipolar input (DI) is intended for 24 V unipolar signal level.
The DO output is a short circuit proof digital output, current sourcing type, 24 V d.c., 0.5 A.
All signals are individually isolated.

 Modules and Termination Units User’s Guide
Section A.27 DP820 Incremental Pulse Counter Module

All inputs have overvoltage protection. A maximum voltage of 30 V can be connected without any
damages.
Shielded twisted pair cables with characteristic impedance=100 (+/- 25%) ohm shall be used for
connection of transducers with RS422/5 V /13 mA signals.
The reset circuitry gives a reset signal when the module is inserted until the BLOCK signal is
inactive and the POWOK signal is active. The BLOCK signal is deactivated when the module lock
mechanism is in the locked position. The POWOK comes from the FCI after power is applied.
Input Filter
Each DP820 input has a configurable input filter (see Technical Data). Notice the following
restrictions for selection of filters for inputs A or B:
The 1µs filter shall always be used when 12 V and 24 V inputs are used.
Unfiltered inputs can be used if RS422/+5 V /13 mA inputs are used, but cables between transducers
and the DP820 module must then be separated from other cables to avoid that extra pulses occur due
to EMI.
Pulse Encoding
The following different methods for pulse encoding are supported by DP820:
• Input A is used for counting up, input B is used for counting down, u/d.
• Input A is used for pulse counting, input B is used to determine count direction, c/d,
B=0: down, B=1: up.
• Input A and B is used for a quadrature encoded signals. Multiplication factors
*1, *2 and *4 can be specified. Count direction is determined by A and B phase shift:

Up count ABB: ... 00 10 11 01 00 10 ...

Down count ABB: ... 11 10 00 01 11 10 ...

Pulse Count (Length/Position) Measurement

Pulse count is done by pulse accumulation in a 29-bit (28bit + sign) bidirectional pulse counter.
The pulse counter value is normally continuously loaded into the pulse register (see block diagram).
A pulse count sample condition can be specified by the user. When a sample condition is fulfilled is
the value in the pulse register “freezed”. The value in the pulse register will remain “freezed” until a
freeze disable command is received from the controller. The pulse accumulation in the pulse counter
continues during the time when the pulse register is frozen
The value of the pulse register (that is, actual pulse count value or “freezed” value) is read by the
CPU, and transferred to the controller.
The pulse counter is synchronized (that is, set to zero) if a user selectable synchronization condition
is fulfilled.

3BSE 020 924R301 265

Modules and Termination Units User’s Guide
Appendix A Specifications

A comparator is used to compare the value of the pulse counter with the content of the compare
register. The value of the compare register is specified by the user. A “coincidence” occur when a
equal condition is detected by the comparator.
The coincidence function can be used to control the digital output signal (DO), as pulse count
sample condition, as synchronization condition and as frequency sample condition (see below).
The pulse counter has overflow detection.

Gated Count Mode

In gated count mode the pulse counter only counts when the gate is active. The gate is controlled by
the DI input. The gate can be controlled in two different ways:
• The DI input is level sensitive, that is, the counter only counts when DI = high.
• The DI input is edge sensitive, that is, the counter starts count on a positive edge on the DI input,
stops on the next positive edge, continues on the next positive edge, and so forth.

Section A.27 DP820 Incremental Pulse Counter Module

Frequency (speed) Measurement.

The frequency measurement function consists of two counters, that is, the SX and SR counters (see
block diagram). The SX counter is used to count number of pulses (Sx) from the unknown input
frequency. The SR counter is used to count the number of pulses (Sr) from a reference frequency
source with frequency FREF. The frequency value (Fx) is calculated as:
Fx = FREF * Sx / Sr
The SX counter is implemented by a 24 bit up/down counter (23 bit + sign). The SR counter is
implemented by a 24 bit up-counter.
The SX and SR counters accumulates pulses during a measurement period. The measurement period
can be determined in two different ways (user selectable):
• By a measurement interval timer.
• By the coincidence comparator function.
With the first method is a measurement interval for each channel defined by the user in increments
of 1 ms from 1 to 2,000 ms. By changing the measurement interval the user can select a suitable
filter time (integration time) with respect to the application’s requirements.
With the second method is the measure interval controlled by the coincidence function, that is, a
measurement interval is started when a coincidence is detected. Next coincidence terminates the
measurement interval, and starts a new measurement interval.
At the end of each measurement period are the SX and SR registers is updated with the value of the
SX and SR counters. The CPU reads the content in the SX and SR registers and calculates a
frequency value.
It is possible to synchronize frequency measurements between the two channels, that is, the
measurement period from one of the channels is then used by both channels.
A frequency sample condition can be specified by the user. When a sample condition is fulfilled is
the value in the SX and SR registers “freezed”. The value in the SX and SR registers will remain
“freezed” until a freeze disable command is received from the controller. The pulse accumulation in
the SX and SR counters continues during the time when the SX and SR registers is frozen
The reference counter (SR) has a overflow detection function. The SR overflow will be activated if
no incoming pulses has been detected during 4.3 s. When the CPU detects SR overflow, is the
frequency value set to zero.

Digital Output
The digital output function can be configured in four different ways:
1. The digital output DO is activated when coincidence occur, and inactivated after a
configurable pulse-length (1ms - 65535 ms).
2. The digital output DO is activated when DOVALUE =1, and inactivated after a configurable
pulse-length (1ms - 65535 ms). The function is retriggable.
3. The digital output DO is activated when DOVALUE=1, and deactivated DOVALUE=0.
4. The digital output DO is activated when coincidence occur and the DOVALUE =1, and
inactivated when DOVALUE=0.

OSP Function
The digital outputs will be set to a predetermined value if the OSP-watchdog timer expires or if the
SetOSPState command is received. The watchdog timer is re-triggered every time the correct
module address has been decoded (or broadcast). If the watchdog timer expires or if the
SetOSPState command is received, the module enters the OSP state.

The function in OSP state, and when reentering the operational state, will be different depending on
how the DO function is configured (see Digital Output 1 - 4 above):

268 3BSE 020 924R301

 Modules and Termination Units User’s Guide
Section A.27 DP820 Incremental Pulse Counter Module

1. Function in OSP state: No more pulses will be activated as long as the module remains in
OSP state. The DO pulse is always completed if the OSP-state is entered during an active DO
pulse (this is, the pulse width is always in accordance with the DOTIME value).
Function when reentering operational state: The coincidence function has to be enabled
before normal DO function will start.
2. Function in OSP state: Same as in 1. above. Function when reentering operational state: A
new
DO-pulse will be started as soon as a modulebus frame with DOVALUE=1 is received.
3. Function in OSP state: The digital outputs are set to their OSP values which can be configured
as a predefined value or to use last good value sent.
Function when reentering operational state: The outputs keeps the OSP value until a
modulebus frame with a new DOVALUE value is received.
4. Same as 3.

Description
The TU810 is a 16 channel 50 V compact module
termination unit (MTU) for the S800 I/O. The MTU is a
passive unit used for connection of the field wiring to the
I/O modules. It also contains a part of the ModuleBus.
The TU810 MTU can have up to 16 I/O channels and two Row C L1+ C1 2 3 4 5 6 7 C8 L2+

process voltage connections. The maximum rated voltage Row B L1+ B1 2 3 4 5 6 7 B8 L2+
is 50 V and maximum rated current is 2A per channel.
Two mechanical keys are used to configure the MTU for Row A L1- A1 2 3 4 5 6 7 A8 L2-

different types of I/O modules.

The MTU distributes the ModuleBus to the I/O module and
to the next MTU. It also generates the correct address to the I/O module by shifting the outgoing
position signals to the next MTU.

 Modules and Termination Units User’s Guide
Section A.28 TU810 Compact MTU

Two mechanical keys are used to configure the MTU for different types of I/O modules. This is only
a mechanical configuration and it does not affect the functionality of the MTU or the I/O module.
Each key has six positions, which gives a total number of 36 different configurations.
The configuration can be changed with a screwdriver.
The MTU can be mounted on a standard DIN rail. It has a mechanical latch that locks the MTU to
the DIN rail. The latch can be released with a screwdriver.
The MTU has a mechanical locking mechanism that locks the module in its position.
This mechanism also gives the signal BLOCK to the I/O module that keeps the module in its init
state until it is locked in its position.
The process signal terminals are divided into 2 equal and individually isolated groups. Each group
consists of 8 I/O connections, one process voltage connection and 5 common L- connections.
The top part of the MTU can be removed to replace the termination board even with an operational
system. Such a need can be caused by a damaged terminal screw.

Description
The TU814 is a 16 channel 50 V compact module
termination unit (MTU) for the S800 I/O. The TU814 has
three rows of crimp snap-in connectors for field signals and
process power connections. The MTU is a passive unit used
for connection of the field wiring to the I/O modules. It also Row C

contains a part of the ModuleBus.

Row B
The TU814 MTU can have up to 16 I/O channels and two
process voltage connections. The maximum rated voltage is Row A

50 V and maximum rated current is 2 A per channel.

Two mechanical keys are used to configure the MTU for
different types of I/O modules. Snap-on connector positions

The MTU distributes the ModuleBus to the I/O module and

to the next MTU. It also generates the correct address to the I/O module by shifting the outgoing
position signals to the next MTU.

 Modules and Termination Units User’s Guide
Section A.31 TU814 Compact MTU

Two mechanical keys are used to configure the MTU for different types of I/O modules. This is only
a mechanical configuration and it does not affect the functionality of the MTU or the I/O module.
Each key has six positions, which gives a total number of 36 different configurations.
The configuration can be changed with a screwdriver.
The MTU can be mounted on a standard DIN rail. It has a mechanical latch that locks the MTU to
the DIN rail. The latch can be released with a screwdriver.
The MTU has a mechanical locking mechanism that locks the module in its position.
This mechanism also gives the signal BLOCK to the I/O module that keeps the module in its init
state until it is locked in its position.
The process signal terminals are divided into 2 equal and individually isolated groups. Each group
consists of 8 I/O connections, 2 process voltage connection and 5 common L- connections.
The top part of the MTU can be removed to replace the termination board even with an operational
system. Such a need can be caused by a damaged terminal screw.
Crimp terminals are provided for connection to field wiring and insertion into the 3 snap-on
connectors. Once the contacts are correctly placed in the connectors, the cable can be easily inserted
and removed without future wiring errors. This assembly function can be performed before the
cables are delivered to the site.

The TU838 MTU can have up to 16 I/O channels. The maximum rated voltage is 50 V and
maximum rated current is 3 A per channel. Two mechanical keys are used to configure the MTU for
different types of I/O modules.

Section A.37 TU838 Extended MTU

The MTU distributes the ModuleBus to the I/O module and to the next MTU. It also generates the
correct address to the I/O module by shifting the outgoing position signals to the next MTU.
The MTU can be mounted on a standard DIN rail. It has a mechanical latch that locks the MTU to
the DIN rail. The latch can be released with a screwdriver.
Two mechanical keys are used to configure the MTU for different types of I/O modules. This is only
a mechanical configuration and it does not affect the functionality of the MTU or the I/O module.
Each key has six positions, which gives a total number of 36 different configurations.
The configuration can be changed with a screwdriver.
The MTU has a mechanical locking mechanism that locks the module in its position.
This mechanism also gives the signal BLOCK to the I/O module that keeps the module in its init
state until it is locked in its position.
The process signal terminals are divided into two equal and individually isolated groups. Each group
consists of 8 I/O channels, 4 fused transducer power outlets, 4 return connections and process
voltage connection. Process voltage can be connected to two individually isolated groups, only valid
if the I/O module supports that.
