1. DESIGN PRECAUTIONS

Reference

• Make sure to have the following safety circuits outside of the PLC to ensure safe system operation even during
external power supply problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a protection circuit, an interlock circuit for
opposite movements (such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the
equipment at the upper and lower positioning limits).
2) Note that when the PLC CPU detects an error, such as a watchdog timer error, during self-diagnosis, all
outputs are turned off. Also, when an error that cannot be detected by the PLC CPU occurs in an input/output
control block, output control may be disabled.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
24
• For the operating status of each node in the case of a communication error, see the FX3U-CAN user’s manual and
the product manual of each node.
Erroneous output or malfunctions may cause an accident.
• When executing control (data changes) to an operating PLC, construct an interlock circuit in the sequence program
so that the entire system operates safely. In addition, when executing control such as program changes and
operation status changes (status control) to an operating PLC, carefully read the manual and sufficiently confirm
safety in advance. Especially in control from external equipment to a PLC in a remote place, problems in the PLC
may not be able to be handled promptly due to abnormality in data transfer. Construct an interlock circuit in the
sequence program. At the same time, determine the actions in the system between the external equipment and the
PLC for protection against abnormalities in data transfer.

Reference

• Make sure to observe the following precautions in order to prevent any damage to the machinery or accidents due
to abnormal data written to the PLC under the influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main circuit, high-voltage line or load line.
Otherwise, noise disturbance and/or surge induction are likely to take place. As a guideline, lay the control line 24
at least 100mm (3.94") or more away from the main circuit or high-voltage lines.
2) Ground the shield wire or shield of a shielded cable.
Do not use common grounding with heavy electrical systems (refer to the manual of the PLC main unit).

• Install module so that excessive force will not be applied to communication connectors or communication cables.
Failure to do so may result in wire damage/breakage or PLC failure.
• Make sure to affix the CAN bus connector with fixing screws.
Tightening torque should follow the specifications in the manual.
Loose connections may cause malfunctions.
• Make sure to properly wire to the terminal block (CAN bus connector) in accordance with the following precautions.
Failure to do so may cause electric shock, equipment failures, a short-circuit, wire breakage, malfunctions, or
damage to the product.
- The disposal size of the cable end should follow the dimensions described in the manual.
29
- Tightening torque should follow the specifications in the manual.
- Twist the end of strand wire and make sure that there are no loose wires.
- Do not solder-plate the electric wire ends.
- Do not connect more than the specified number of wires or electric wires of unspecified size.
- Affix the electric wires so that neither the terminal block nor the connected parts are directly stressed.
• Make sure to observe the following precautions in order to prevent any damage to the machinery or accidents due
to abnormal data written to the PLC under the influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main circuit, high-voltage line or load line.
Otherwise, noise disturbance and/or surge induction are likely to take place. As a guideline, lay the control line
at least 100 mm (3.94") or more away from the main circuit or high-voltage lines.
2) Ground the shield wire or shield of a shielded cable.
Do not use common grounding with heavy electrical systems.
• Place the communication cable in grounded metallic ducts or conduits both inside and outside of the control panel
whenever possible.

1.1.2 Overview of FX3U-CAN communication block

CANopen ready I/O stations and device stations can be connected to the CAN bus and information can be
transmitted to the FX3U-CAN communication block and FX3G/FX3GC/FX3U/FX3UC/FX5U/FX5UC PLC.

1. The maximum send / receive message number

80 TPDO /80 RPDO (8 bytes / PDO) can be sent and received to/from a CANopen network.

2. CANopen device/application Profiles according to CiA® Standards

• Interface and Device Profile CiA® 405 V2.0 for IEC 61131-3 Programmable Devices.
• Application Profile CiA® 417 V2.1 for lift control systems.

3. Communication with other CANopen nodes

All nodes on the CANopen network can write data to all the other nodes on the network. Each piece of data
has a unique identifying number that is read by the receiving nodes to determine whether that data should be
kept in the receiving nodes' Buffer Memory.
The FX3U-CAN communication block uses buffer memories to communicate on the CAN bus. Each buffer
memory is separated into memory dedicated to write TO and memory dedicated to read FROM the CAN bus.
These Buffer Memories are accessed by FROM/TO commands of the PLC. However, only FX3U/FX3UC/
FX5U/FX5UC PLC supports direct specification of the buffer memory.
For further information on applied instructions, bit specification of word devices and direct specification of
buffer memory, refer to the following manual.
Refer to PROGRAMMING MANUAL
Note
Buffer memory that is assigned in 32 bits must use 32-bit instructions to read/write.
32-bit data cannot be correctly read/written from/to buffer memory if 16-bit read/write instructions are used.

1.1.3 Characteristics
This section describes the characteristics of the CAN bus, communication with other CANopen nodes, and
some of the special features available in the CANopen protocol.

1. The object dictionary

The Object Dictionary is a type of indexed storage system that contains data, device parameters, CANopen
feature setup data, instruction triggers, and other information necessary to configure and operate the
CANopen protocol.

2. SDO command
The Service Data Object Command can be used to read/write data to the Object Dictionary.
This command can be used to set network parameters and also to initiate CANopen functionality.

3. SYNC service
The SYNC service provides the basic network synchronization mechanism.

4. TIME service
The TIME service provides a simple network clock. CANopen devices that operate a local clock may use the
TIME object to adjust their own time base to that of the time stamp object producer.

5. EMCY object service

Emergency objects are triggered by the occurrence of a CANopen device internal error situation and are
transmitted from an emergency producer on the CANopen device.

node and is located in the BFM. Access is performed by commands for SDO read/write, special direct
command for Node Guarding, Heartbeat, PDO Mapping or Emergency Messages.

8. NMT master
The network management provides services for controlling the network behaviour of CANopen devices as 3
defined in CiA® 301 and CiA® 302. All CANopen devices of a network referred to as NMT slaves are

Installation
controlled by services provided by an NMT master.

9. Flying master
The flying master mechanism provides services for a hot stand-by NMT master within a CANopen network.

10.Configuration manager 4

DESIGN PRECAUTIONS

• Make sure to have the following safety circuits outside of the PLC to ensure safe system operation even during external power supply
problems or PLC failure.
Otherwise, malfunctions may cause serious accidents.
1) Most importantly, have the following: an emergency stop circuit, a protection circuit, an interlock circuit for opposite movements
(such as normal vs. reverse rotation), and an interlock circuit (to prevent damage to the equipment at the upper and lower
positioning limits).
2) Note that when the PLC CPU detects an error, such as a watchdog timer error, during self-diagnosis, all outputs are turned off.
Also, when an error that cannot be detected by the PLC CPU occurs in an input/output control block, output control may be
disabled.
External circuits and mechanisms should be designed to ensure safe machinery operation in such a case.
• For the operating status of each node in the case of a communication error, see the FX3U-CAN user’s manual and the product
manual of each node.
Erroneous output or malfunctions may cause an accident.
• When executing control (data changes) to an operating PLC, construct an interlock circuit in the sequence program so that the entire
system operates safely. In addition, when executing control such as program changes and operation status changes (status control)
to an operating PLC, carefully read the manual and sufficiently confirm safety in advance. Especially in control from external
equipment to a PLC in a remote place, problems in the PLC may not be able to be handled promptly due to abnormality in data
transfer. Construct an interlock circuit in the sequence program. At the same time, determine the actions in the system between the
external equipment and the PLC for protection against abnormalities in data transfer.

DESIGN PRECAUTIONS

• Make sure to observe the following precautions in order to prevent any damage to the machinery or accidents due to abnormal data
written to the PLC under the influence of noise:
1) Do not bundle the main circuit line together with or lay it close to the main circuit, high-voltage line or load line.
Otherwise, noise disturbance and/or surge induction are likely to take place. As a guideline, lay the control line at least 100mm
(3.94") or more away from the main circuit or high-voltage lines.
2) Ground the shield wire or shield of a shielded cable.
Do not use common grounding with heavy electrical systems (refer to the manual of the PLC main unit).

DISPOSAL PRECAUTIONS

• Please contact a certified electronic waste disposal company for the environmentally safe recycling and disposal of your device.

TRANSPORTATION AND
STORAGE PRECAUTIONS
• The PLC is a precision instrument. During transportation, avoid impacts larger than those specified in the general specifications of the
PLC main unit manual by using dedicated packaging boxes and shock-absorbing palettes.
Failure to do so may cause failures in the PLC. After transportation, verify operation of the PLC and check for damage of the mounting
part, etc.

FX3U-CAN User's Manual 5.3 Object Dictionary

5.3 Object Dictionary

The Object Dictionary is a structure for data organization within the CANopen network. The data within the
Object Dictionary is used to set CAN bus parameters, initialize special functions, control data flow, store data
in many formats and send emergency messages.
The Object Dictionary is structured in Indexes and Sub-Indexes. Each Index addresses a single parameter, a
set of parameters, network input/output data or other data. A Sub-Index addresses a subset of the parameter
or data of the Index.

General layout of CANopen standard object dictionary

The general layout of the CANopen standard object dictionary is shown below.

5.6.1 CAN-ID / COB-ID

Introduction
Each message type on each device has a unique 11-bit identifier for bus arbitration and identification on the
CAN bus. The lowest CAN-ID wins the bus arbitration. CAN-IDs with lower priority (higher CAN-ID) will wait
until the bus is free.
For easier configuration, one CAN-ID scheme exists for all CANopen devices. By default four TPDO and four
RPDO are reserved for every Node-ID. To use more PDO for one node, it is necessary to use CAN-IDs of

The Generic error bit will always be set as long as the EMCY error code is bigger than H00FF.
The Error Register can be cleared by clearing the Pre-defined error field in object H1003.
All of these bits can be set by the Emergency message transmission command in the Command Interface.
For EMCY, refer to Subsection 5.6.13
For pre-defined error field, refer to Subsection 5.6.3
For emergency message transmission command, refer to Section 10.5

5.6.3 Pre-defined error field

This object H1003 provides the errors that occurred on the module and were signalled via the emergency
object.
1) Sub-index H00: Number of errors
The Sub-index H00 displays the number of errors that are recorded. Writing H0 to this Sub-index deletes
the entire history. Write values other than H0 are not allowed.
2) Sub-index H01 to H0F: Standard error fields
List of the last 15 EMCY Errors sent by FX3U-CAN. Sub-index H01 contains the newest Message and
Sub-index H0F contains the oldest Message.
For Emergency error codes, refers to Section 6.23

5.6.4 SDO
An SDO provides direct access to object entries of a CANopen device's object dictionary. These object
entries may contain data of arbitrary size and data type. SDO is used to transfer multiple data sets from a
client to a server and vice versa. The client controls which data set to transfer via a multiplexer (index and
sub-index of the object dictionary). By using the CIF, it is possible to make an SDO access to other CANopen
devices or to the FX3U-CAN itself. In the Object Dictionary, no configuration needed.

5.6.5 RPDO / TPDO

Introduction
Real-time data transfer is performed by means of Process Data Objects (PDO). PDO transfer is performed
with no protocol overhead.
PDOs correspond to objects in the object dictionary and provide the interface to the application objects. Data
type and mapping of application objects into a PDO is determined by a corresponding default PDO mapping
structure within the object dictionary. The variable mapping of PDO and the mapping of application objects
2

Specifications
into a PDO may be transmitted to a CANopen device during the configuration process by applying the SDO
services to the corresponding objects of the object dictionary.
The PDO communication parameter describes the communication capabilities of the PDO. The PDO
mapping parameter contains information about the contents of the PDO.

Introduction
The SYNC producer broadcasts the synchronization object periodically. The SYNC message provides the
basic network synchronization mechanism. The time period between SYNC messages is specified by the

5.6.8 Node guarding

This protocol is used to detect remote errors in the network. Each NMT slave serves one requests message
for the node guarding protocol.
The NMT master polls each NMT guarding slave at regular time intervals. This time-interval is called the
guard time and may be different for each NMT slave. The response of the NMT slave contains the NMT state
of that NMT slave. The node lifetime is given by guard time multiplied by lifetime factor. The node lifetime may
be different for each NMT slave. If the NMT slave has not been polled during its lifetime, a remote node error
is indicated through the NMT service life guarding event. A remote node error is indicated through the NMT
service node guarding event if:
NMT master:
• The NMT master does not receive confirmation after the Guarding request within the node life time.
• The response of the NMT guarding slave state does not match the expected state.
NMT slave:
• The NMT guarding slave did not receive the NMT master Guarding request polling for time set in H100C
and H100D.

If a remote error occurred previously but the errors in the guarding protocol have disappeared, it will be
indicated that the remote error has been resolved through the NMT service node guarding event and the NMT
service life guarding event.
If Heartbeat is activated, the Node guarding settings will be ignored.
Note

• As Slave, the FX3U-CAN (firmware Ver. 1.10 or later) supports Node Guarding.
Use the heartbeat service for FX3U-CAN not supporting Node Guarding.
• Node guarding produces a high bus load. It is recommended to use heartbeat instead.

5.6.9 Heartbeat

Introduction
The heartbeat protocol defines an error control service that does not use requests. A heartbeat producer
transmits a heartbeat message cyclically. One or more heartbeat consumers receive the indication. The
relationship between producer and consumer is configurable via the object dictionary. The heartbeat
consumer guards the reception of the heartbeat within the heartbeat consumer time. If the heartbeat is not
received within the heartbeat consumer time, a heartbeat event will be generated.
2

Specifications
If the FX3U-CAN module is configured as Flying Master, Heartbeat producing and consuming is automatically
activated between it and other FX3U-CAN modules also set up as Flying Masters.

5.6.10 TIME
The TIME producer broadcasts the time stamp object. This TIME provides the simple network clock. The time
stamp contains the Time of day, which is represented by a 48 bit sequence. These sequences represent the
time in milliseconds after midnight (28 bits) and the number of days since 1984-01-01 (16 bits). Only one
Timestamp producer is allowed in the Network.
The time and the date have to be configured by setting BFM #51 to #57 (clock data).
In order to guarantee timely access to the network, the TIME is given a very high priority CAN-ID. CANopen
devices that operate a local clock may use the TIME object to adjust their own time base to that of the time
stamp object producer.
The consuming and producing setting can be directly changed by BFM #50.
In case of time overflow (time later than 31st December 2099 23:59.59), the time returns to 1st January 2000

5.8 Network Management

The NMT provides services for controlling the network behaviour of CANopen devices. All CANopen devices
of a network referred to as NMT slaves are controlled by services provided by an NMT master. The NMT
master is typically also the Application master at the same time, but it is not necessary.
The FX3U-CAN supports the master functions NMT startup master, Flying master, Configuration manager,
SYNC producer, TIME producer and LSS master which are described in the sections before and below.

5.8.1 CANopen Boot-Up Procedure and NMT states

CANopen devices shift to the NMT state Pre-operational directly after finishing device initialization. In this
NMT state, CANopen device parameterization and CAN-ID-allocation via SDO (e.g. using a configuration
tool) is possible. Then the CANopen devices may be switched directly or by the NMT startup master into the
NMT state Operational.

In the NMT state Pre-operational, communication via SDO is possible. PDO communication is not allowed.
Configuration of PDO, parameters and also the allocation of application objects (PDO mapping) may be
performed by a configuration application. The CANopen device may be switched into the NMT state
Operational directly by sending the NMT service start remote node.

Introduction
By switching a CANopen device into the NMT state Stopped, it is forced to stop all communication.
Furthermore, this NMT state may be used to achieve certain application behaviour.

5.8.4 NMT slave identification

The NMT startup master and the LSS master are using the NMT slave identification data to identify the NMT
slave before configuring the NMT slave.
If the configured identification data on the NMT master are different than responded from the NMT slave, the
NMT startup master service will stop the startup of this NMT slave.
The Sub-index corresponds to the NMT slave Node-ID. The default value 0 has the meaning not configured,
and the NMT master will skip this entry.
For the LSS Master all NMT slave Identification data need to be configured! For the NMT Startup Master, the
NMT slave identification entries are optional.

5.8.5 NMT master startup

The NMT startup master behaves according to the NMT state machine as defined in Subsection 5.8.1. Before
the NMT master transitions from NMT state Pre-operational to NMT state Operational, all assigned NMT
slaves shall be booted.
The Main flow chart for the NMT master startup is shown in Figure 5.1
Figure 5.2 is a simple startup overview to show the influence of the BFM #70 setting. It is recommended not to
use the simple startup because it can not be guaranteed that every NMT Slave will be set into Operational
state. Setup the NMT slave startup values for every connected NMT slave on the NMT master instead.

Introduction
This object configures the start up behaviour of a CANopen device via SDO access. If the node is set as
Master without the flying master capability, the node starts as NMT master and ignores "all Nodes" NMT
commands from the network. After the FX3U-CAN has been configured as the NMT master, parameters have
to be stored, and the FX3U-CAN has to be restarted by BFM #25 bit 0 or NMT request Reset Node.

5.8.6 NMT slave startup

If the NMT Master shall startup the NMT Slave, the NMT startup Master uses the Indexes H1F84 to H1F88 to
identify the NMT Slaves during Boot-up. The Setting of these Indexes is optional.
The NMT startup Master will request the Index H1000 of the NMT slave to check if the NMT Slave is available
in the network. If there is no response on the request, the NMT Master retries every 1s after the request until
the NMT Slave responds to the request or the boot time for a mandatory Slave elapses without response.
The Index H1F89 Boot time shall be set to a value which is higher than the maximum NMT startup time of the
slowest mandatory slave. This time has to be measured from Power-on/Reset of the NMT master to the point
where the last mandatory slave becomes NMT state Operational.
If identification data of NMT Slaves do not match with the setting on the NMT Master, it will result in a
termination of the whole NMT Startup process and the NMT startup Master will be disabled.
After a successful Identification, the Configuration Manager configures the NMT Slave at the time when
configuration data are stored on the NMT Master.
At last depending on the setting, the NMT Master sets the NMT Slave into NMT state Operational.
For NMT Slave identification, refer to Subsection 5.8.4
For NMT Master startup process, refer to Figure 5.1
For Configuration Manager, refer to Subsection 5.8.13
Note
For correct functioning of the CANopen network, it is recommended to assign all CANopen devices which are
NMT Slave to the NMT Master.

5.8.11 Flying Master

The Flying Master mechanism provides services for a hot stand-by NMT Master within a CANopen network.
All Flying Masters shall monitor the Heartbeat of all masters in the network. A new negotiation is automatically
started if the active master fails. The master with the highest priority and the lowest node-ID wins the
negotiation. A new negotiation is started when a new NMT master with a higher priority than the active NMT
Master join the network. The Flying NMT master priority is defined by (NMT master priority level  128 +
Node-Id), the lower value has the higher priority.
BFM #25 bit 15 indicates if the module is the current NMT Master.
Note

• If the module has enabled the Flying Master function and no Heartbeat producing is set, the Heartbeat
producing is automatically set to 1000 ms.
• If the module loses the negotiation and no Heartbeat consuming is set for the active NMT master,
Heartbeat consuming is automatically set to (1500 + 10  Node-ID) ms.
• If the Heartbeat producing and consuming is set manually, set a different value for the consuming time of
one Node-ID on the other Flying masters so that multiple masters will not initiate at the same time a new
Flying master negotiation when the active NMT master times out.
• If a Flying Master is in the Network which is not a FX3U-CAN, ensure that this node has Heartbeat
producing enabled, otherwise the FX3U-CAN with activated Flying Master function will send endless Reset
Communication NMT Messages!
For the Communication Status (BFM #25), refer to Section 6.8
• All Flying Masters should have the same configuration for the Slaves.
• Configure in the Flying master negotiation response wait time of all Flying Master.
Formula for the Flying Master negotiation response wait time:

Flying Master negotiation response wait time =

(NMT master priority)  (Priority time slot) + (Node-ID)  (Node time slot)
• During the Flying master negotiation process, an NMT service Reset communication message will be sent
to all nodes.

Point

Introduction
When using the Flying Master function, please consider the following points:
• The Network communication will be reset after the Active NMT Master fails which will result in an
Interruption of the System Application.
• Application data will be not synchronized by the Flying Master mechanisms. This has to be handled by a 2
proper CANopen configuration and CANopen system planning.

Specifications
• Be careful with the setting of the NMT flying master timing parameters. An inappropriate setting will result
in a Malfunction of the Flying Master negotiation. Test the System Configuration before field use.

5.8.12 LSS

Introduction
The FX3U-CAN uses the layer setting services and protocols, to configure via the CAN network the Baud Rate
and the Node Address of an LSS slave device that is sealed against harsh environments and that does not
have any hardware components like DIP-switches for setting the node-ID or bit timing parameters.
Within a CANopen network, only one LSS-Master is allowed to exist. For the LSS-Master Mode the module
has to be the active NMT-Master.
2

Specifications
To activate the LSS Master, configure in the Object dictionary:
• Index H1F89:
The Boot time out. The time shall be longer than the boot time of the NMT-Client, which needs the longest
time for boot-up (Power On until Boot-up message).
• Indexes H1F84 to H1F88, the Sub-index which corresponds to the Node-Id which shall be set at the LSS- 3
Client:

Installation
The Identification information which is available at the Object dictionary Indexes H1000 and H1018 at the
LSS-Client.
• Index H1F81, the Sub-index which corresponds to the Node-Id which shall be set at the LSS-Client:
Set bit 0 NMT Slave, bit 2 NMT boot slave and bit 3 Mandatory device.
If the LSS Slave is not found on the configured baud rate, the FX3U-CAN changes automatically the baud rate 4
to find the LSS Slave. Through communication with a different baud rate, it can come to a Bus off condition at

Wiring
the other devices in the network. If the device does not support automatically recovering from Bus off or
needs too much time for recovering, it's not possible to configure the LSS-Client.
It is recommended to establish a Point to Point connection for the configuration and to delete the Serial
number entry (Index H1F88) after configuration to prevent an unwanted start of the LSS Master.
For Boot time, refer to Object Dictionary Index H1F89 in Section 5.6
For NMT slave identification, refer to Object Dictionary Index H1F84 to H1F88 in Subsection 5.8.4

1. Object H1020: Verify configuration

This object indicates the downloaded configuration date and time on the NMT Slave. A configuration manager
uses this object to verify the configuration after a reset to check if a reconfiguration is necessary. If on a NMT
Slave the Object dictionary configuration is changed, the Sub-indexes H01 and H02 values will be set to H0.
At the time of NMT Slave boot-up, the Configuration manager compares the corresponding entries of H1020
on the Slave with its own setting in the Indexes H1F26 and H1F27 (see below) and decides if a
reconfiguration is necessary or not. This mechanism reduces the time of NMT Slave bootup.
Sub-index H01: Configuration date; contains the number of days since 1984-01-01.
Sub-index H02: Configuration time; contains the number of ms after midnight.

2. Object H1F22 Sub-index H01 to H7F: Concise DCF

These objects save a configuration file with the Concise DCF format into the node-ID corresponding sub-
index. A CANopen configuration software and a CAN-Bus PC-Interface is necessary for the generation of a
CANopen configuration and saving over the CAN Bus.
Up to 60 Concise DCFs can be stored on the FX3U-CAN. The maximum size for each entry is 65531 byte.

Note

• To delete a Sub-index entry write "0" to this Sub-index. Erasing an entry requires 2 to 10 seconds. During
this time, it is not possible to write a new file.
If the Flash ROM is busy, an SDO write access error H06060000 will occur.
• When the FX3U-CAN responds to an SDO write access to a Sub-index with SDO Error H06010002, this
Sub-index already had been used. Delete the Sub-index entry by using the aforesaid method.
• When the FX3U-CAN responds to an SDO write access to a Sub-index with SDO access Error H06070010,
the CDCF File is bigger than 65531 bytes, or this Sub-index has already been used. Check the File size
and delete the Sub-index entry by using the aforesaid method.
• If the used CANopen configuration software has a problem with the automatic transfer of the Concise DCF
be cause of Flash ROM busy errors, please use the selective download of the files if supported.
• All H1F22 Sub-indexes can also be deleted by the Restore default parameter command.
• Self-configuration over the Sub-Index of the entry corresponding to own Node-Id is not supported.
• The Concise DCF data will be directly stored on the Flash ROM. A Store parameters command over
Object Dictionary Index H1010 is not necessary (Refer to Section 4.6.11).
For Store parameters, refer to Subsection 5.6.11
For Restore default parameters, refer to Subsection 5.6.12

3. Object H1F25 Sub-index H01 to H80: Configuration request

To initiate a configuration request for a CANopen node, use the SDO write command in the CIF and write
H666E6F63 (ISO8859 String code: "conf") to the corresponding sub-index of the FX3U-CAN. The sub-index
H80 initiates a configuration request for all CANopen devices in the network for which CDCF data are stored.
A configuration request to the self node-ID will be ignored and no error response will be generated.
For Sub-index H01 to H7F, a SDO failure H08000024 will occur if no data are stored for this Node-Id.
A configuration request to the Sub-index of the entry corresponding to own Node-Id will be ignored.
For SDO write command in the CIF, refer to Subsection 10.2.3

4. Object H1F26 Sub-index H01 to H7F: Expected configuration date

This object is used by CANopen configuration software for verification of the configuration date of the
CANopen devices in the network. The value contains the number of days since 1984-01-01.

5. Object H1F27 Sub-index H01 to H7F: Expected configuration time

This object is used by CANopen configuration software for verification of the configuration time of the
CANopen devices in the network. The value contains the number of ms after midnight.

5.10 Application Profile CiA 417 V2.1 for Lift Control Systems

Introduction
This application profile describes the virtual devices (hereinafter called VD) of lift control systems. The virtual
controllers (e.g. call, car door, and car drive controller) perform dedicated control functions of the lift
application. The virtual units (e.g. input and output panels, car door, light barrier, car position, car drive, load-
measuring) are implemented each in single CANopen devices or combined in one or more CANopen devices. 2
The FX3U-CAN implements the VD call controller, car drive controller and the car door controller.

Specifications
The VD Call controller receives all call requests from these VD input panels, and transmits the corresponding
acknowledgements to the VD output panels. The VD car door controller transmits commands to the VD car
door unit and the VD light barrier unit. The VD car driver controller transmits commands to the VD car drive
unit. It receives status information from the VD car drive unit and the VD load-measuring unit. If the profile
position mode is used, additional status information from the VD car position unit is needed. It is
recommended to give the Call controller the lowest node-ID.
3

Installation
The lift control system application profile shares the Object Dictionary area from H6000 to H9FFF. The area
from H6000 to H60FF is related to the CANopen device and not to one of the lift-control applications. The
area from H6100 to H62FF is related to the VD input panel units, they do not belong to a specific lift control.
The Indexes H6010 and H6011 are related to the VD Call controller and do not belong to a specific lift control.
It is possible to realize up to 8 lift-control applications. For the specific lift control application 1, the area H6200
to H67FE is used. For other lift control applications, the area H6200 to H67FE is shifted as follows: 4

6.2 How to Read/Write from/to Buffer Memory

To read/write from/to buffer memory in the FX 3U -CAN, use the FROM/TO instructions or the applied
instructions that directly specify the buffer memory.
FX3U/FX3UC/FX5U/FX5UC PLC applicable software is required to perform direct specification of the buffer
memory and bit specification of word devices.
For further information on applied instructions, bit specification of word devices, direct specification of buffer
memory or special extension unit/block unit number, refer to following manual.
Refer to Programming manual

6.2.1 Direct specification of buffer memory (FX3U/FX3UC/FX5U/FX5UC only)

When directly specifying the buffer memory, specify the following device in the source or destination area of
the applied instruction as follows:

6.3 Receive/Transmit Process Data

Introduction
BFM #10000 to #10319 and #11000 to #11319 locations in the FX3U-CAN module are used for data
communication to the CAN bus. The mapping for where each data is sent/received is explained in the
following chapter.
When using CANopen 405 mode, refer to Chapter 7 2
When using CANopen 417 mode, refer to Chapter 8

Specifications
When using the 11 bit CAN-ID Layer 2 mode or 29 bit CAN-ID Layer 2 mode,
refer to Chapter 9
Note
In the CANopen 417 Mode (BFM #21 = K417), only BFM #0 to #3, BFM #10000 to #10003 and BFM #11000

Installation
#11319 are not accessible.

6.4 [BFM #20] Data Exchange Control

To ensure that the FX3U-CAN module can handle the CANopen data in a consistent way, it is necessary to 4
set in BFM #20 the corresponding Bit to ON before reading data (FROM) and after writing data (TO). The

Wiring
data exchange control signal ensures, by internal buffer exchange, that TO data from the PLC will be
transmitted by PDO.
PDO transmit data will only be sent to the CAN bus if the module is in NMT state Operational and after setting
the corresponding bits in BFM #20 to ON. As long as the reading of the previous data is not finished and a
new exchange command to BFM #20 has not been sent, FROM data will not be overwritten by further PDO.
If the module is in NMT state Operational, PDO data received from other nodes can be read by the FX3G/ 5
FX3GC/FX3U/FX3UC/FX5U/FX5UC PLC by using a FROM instruction, and transmit PDO data can be written

FX3U-CAN User's Manual 6.9 [BFM #26] FROM/TO Watchdog

6.9 [BFM #26] FROM/TO Watchdog

The FROM/TO Watchdog can be used when the Module is online to monitor if the PLC program accesses
data BFM #0 to BFM #19, BFM #100 to #399 or BFM #3000 to BFM #3539 cyclically.
After the first FROM/TO on the data BFM, the Watchdog will check if the next access to the data BFM takes
place before the time set in BFM #26 expires.
BFM #26 sets the Watchdog timer in 10 ms steps (default value K20 equals 200 ms).
Note

• If the watchdog expires, bit 7 in BFM #29 is set to ON, and the messages defined in the BFM #1900 to
#1927 "PLC RUN>STOP messages" area or an EMCY Object are transmitted on the network. If the
module is in a CANopen Mode, the module will react according to the value set in the Error behavior object
(Index H1029) in the object dictionary.
For PLC RUN>STOP messages, refer to Section 9.6
For EMCY Object, refer to Subsection 5.6.13
 For Error behaviour object, refer to Section 5.7
• If the watchdog function is not required, it can be deactivated by writing K0 to BFM #26.
• The FROM/TO watchdog can be restarted by writing the setting value to BFM #26 again, which will also
reset the error flag in BFM #29.

6.10 [BFM #27] Node Address

This BFM sets CANopen Node-ID. The setting value range is 1 to 127.
Note

• The BFM setting needs to be stored by BFM #22 bit 0 and afterwards be restarted by BFM #25 bit 0 to
make the new setting effective.
• A setting out of the above range or a write access in Layer-2 function mode will generate a Failure
Message in BFM #29 bit 6.

6.19 [BFM #50 to #59] Time Stamp

CANopen devices which operate a local clock may use the TIME object to adjust their own time base to the
time of the time stamp producer.
After power up or reset of the FX3U-CAN, the clock data is set to default values, and the clock is stopped.
FX3U-CAN sets up producer or consumer of Time stamp by BFM #50. When FX3U-CAN is the current
Network Master or Producer, set the clock data to BFM #51 to #59. The current Time stamp of CANopen
network can read the clock data from BFM #51 to #57.
• When the FX3U-CAN is set up as Consumer, the clock starts counting after receiving the first Time stamp
object.
• When the FX3U-CAN is set up as Producer, the clock starts after setup of BFM #50 to #58.
• The FX3U-CAN will only produce the Time stamp if it is the current Network Master and in CANopen state
Operational or Pre-operational.

Note

• After power up or reset of the FX3U-CAN, the clock data is set to default values, and the clock is stopped.
• The data and time will be checked when BFM #56 is written. If value is outside of the allowed range BFM
#29 bit 6 will be set to ON.
For BFM #29 bit 6, refer to Section 14.2
• When the FX3U-CAN is set up as consumer, write access to BFM #51 to #59 will be ignored.
• When FX3U-CAN is the current Network Master and Producer, the first time stamp will be sent after setting
BFM #58.
• There is always a delay in time due to latency during writing to the BFM and during the transmission over
the CAN bus.
• A leap year correction is provided.
• Clock tolerance: ±132 sec/month (at 25°C)
• The resolution of the Time stamp object in the FX3U-CAN is in units of second. All values outside of the
Setting range will be ignored, and the old value will persist. If a Time stamp object is received, BFM #25 bit
12 will be set.
For communication status (BFM #25), refer to Section 6.8

This section explains data transfer locations for CANopen 405 mode. BFM #10000 to #10319 and #11000 to
#11319 are used as data transfer locations.

Note

• The data will be exchanged only when the module is in OPERATIONAL State.
• To ensure that the FX3U-CAN module can handle the CANopen data in a consistent way, it is necessary to
use the data exchange by BFM #20 bit 0 or 8 to ON before reading PDO data (FROM) and after writing
PDO data (TO) to the module.
The data exchange control signal ensures, by internal buffer exchange, that TO data from the PLC will be
transmitted with its corresponding PDO at the same time.

7.1.1 Direct TO BFM Access to the CANopen 405 Object

Use the TO instruction to write data to the following locations. The default TPDO mapping is assigned to
unsigned 16 bit objects (Index HA100).
To change this setting, use the SDO command in the CIF or a CANopen configuration software.
For SDO command in the CIF, refer to Section 10.2
For the CANopen configuration software, refer to the manual of the software to be used
Note
The data which are written to the BFM will only be copied into the Object Dictionary when they are mapped
into a PDO. Example: BFM #11000 is assigned to the Object Dictionary Indexes/Sub-indexes HA240/H01,
HA200/H01, HA1C0/H01, HA100/H01, HA0C0/H01, HA040/H01, H02 and HA000/H01, H02. If none of these
Indexes are mapped into a TPDO, the data will not be copied from the BFM into any of the assigned Object
Dictionary Indexes/Sub-indexes.

7.1.2 Direct FROM BFM access to the CANopen 405 Object

Use the FROM instruction to read data from the following locations. The default RPDO mapping is assigned
to unsigned 16 bit objects (Index HA580).
To change this setting, use the SDO command in the CIF or a CANopen configuration software.
For SDO command in the CIF, refer to Section 10.2
For the CANopen configuration software, refer to the manual of the software to be used
Note
If data is written with an SDO into the Object Dictionary to one of the BFM corresponding Indexes/Sub-
indexes, only the last data written is visible in the BFM. The data of the corresponding Indexes/Sub-indexes
are not synchronized to each other.

FX3U-CAN User's Manual 7.2 PDO Mapping/Binding of the Network for CANopen 405 Mode

7.2 PDO Mapping/Binding of the Network for CANopen 405 Mode

In order to exchange data by CANopen, the data channels between the nodes must be defined or "mapped".
For large networks, the usage of a proper CANopen network configuration tool*1 which is able to support easy
parameter settings and PDO mapping is recommended.
To build up a small network or for testing purposes, the FX3U-CAN supports three PDO mapping/binding
modes which can be executed by the Command Interface. By using these predefined Mapping
configurations, the CAN object ID (COB-ID) number for data exchange of each node is clearly defined.
For function mode setting for CANopen 405 mode, refer to Section 6.5
*1. Example: Vector ProCANopen

Note
It is strongly recommended to execute the Mapping Commands only in the Pre-operational mode of all related
CANopen nodes.
For a complete list of the assignment between the data BFM and the CANopen data objects and their location
in the Object Dictionary, refer to the following section.
Refer to Subsection 7.2.1 and Subsection 7.2.2

Note that the NMT Master startup process uses SDO's which can be result in an Error of the CIF SDO
command if the NMT Startup Master acceses the remote Node at the same time.

Introduction
By executing the Mode 0 mapping command shown below, the number of automatically assigned TPDOs and
RPDOs becomes four. All RPDO/TPDO communication and mapping parameter and the BFM/Object
dictionary assignment will be reset to factory default. The BFM content of the Receive/Transmit Process Data
BFM's will be set to zero.
2
BFM #0 to #15 are distributed to RPDOs and TPDOs 1 to 4 as shown in the TPDO/RPDO mapping table.

Specifications
This setting is useful for a network that features many different types of nodes or as a base for a network
mapping configured with the Mode B mapping command.
The PDOs 5 to 80 (BFM #16 to #19 and #100 to #399) are disabled in the default settings but further mapping
of these PDOs can be accomplished by using the Mode B mapping technique or SDO.

Easy setup of a CANopen network of up to eight FX3U-CAN nodes can be accomplished by simply using the
Mode A Mapping configuration. All FX3U-CAN modules have to be set up via the local PLC. One of the nodes
must be configured as the network master. The network master can be defined in the Network Configuration
tool or by writing to the Object Dictionary using the CIF SDO write command.
All RPDO/TPDO communication and mapping parameter and the BFM/Object dictionary assignment will be
reset to Mode A default. The BFM content of the Receive/Transmit Process Data BFM's will be set to zero. 7

After all stations have executed the Mode A Mapping command, 16 data words can be exchanged with other
FX3U-CAN modules.
A closer look at the mapping shows that the TPDO is dependent upon the node ID but the mapping for the
RPDO is fixed to the default TPDO COB-ID of stations 1 to 8. The advantage is that the data location of all
FX3U-CAN modules is the same. 8

7.2.5 Mode B COB-ID mapping

With Mode B COB-ID Mapping, it is possible to build up bindings between any nodes connected to the FX3U-
CAN module and the FX3U-CAN module itself or any other nodes also connected to the FX3U-CAN. Mode B
COB-ID mapping is limited to the binding of the PDO COB-ID already configured in the remote stations (No
change of the PDO mapping parameter).
All three Mode B COB-ID mapping options can be mixed within one CIF Function call.
Mode B COB-ID Mapping options Reference
Reset Mapping Table to default Mode B COB-ID mapping page 136
Assign Source TPDO COB-ID to Destination RPDO COB-ID page 137
Assign Additional TPDO COB-IDs to the Local Node page 138

The Mode B COB-ID mapping command will modify the current PDO COB-ID at the Destination, therefore it
is important to have a clearly defined mapping base before executing any Mode B commands. Executing the
Mode B COB-ID Mapping commands before adjusting the PDO mapping parameters (adjusting the PDO data
length) may create errors in the data transmission or module operation.
The PDO mapping base can be the "Mode 0" mapping or the "Mode A" mapping explained in previous
sections to prepare default RPDO and TPDO formats. Another method to create (or reset) a Mapping base is
to initialize the Mode B Mapping with a special instruction at the beginning of the Mode B Mapping Command.
If it is necessary to change the remote node hardware mapping, this can be done by the SDO write access
command or by a standard CANopen network configuration tool.
The configuration with the Mode B mapping is controlled by parameters, which are displayed in the table on
the following page.
For the SDO write access command in the CIF, refer to Subsection 10.2.3
For BFM assignment of the Receive/Transmit Process Data BFM's,
refer to Subsection 7.1.1 and Subsection 7.1.2
For the CANopen configuration software, refer to the manual of the software to be used
For the default RPDO and TPDO formats, refer to Subsection 7.2.1 and Subsection 7.2.2

Reset Mapping Table to default Mode B COB-ID mapping

This command sets Mode B default settings on the local Node. All RPDO/TPDO communication and mapping
parameter and the BFM/Object dictionary assignment will be reset to factory default. The BFM content of the

The Destination parameter defines the destination for the corresponding source parameter data. It consists of
two bytes, with the node ID in the high byte and the PDO number in the low byte.
• Node ID
The node ID range is 1 to 127.
The local FX3U-CAN can be specified by its actual node number or by using "0".
• RPDO number
The RPDO number setting range is 1 to 255.
The Destination node COB-ID is checked before the Source data is written to the communication
parameter.

Example:
Destination parameter = H0203
The Source data will be bound to RPDO #3 of Node 2.

Note
An error message will be generated if the destination parameter is not configured.

Assign Additional TPDO COB-IDs to the Local Node

By default every CANopen node uses four COB-IDs to exchange its data with other CANopen stations. All
COB-IDs for Data transmission are by default reserved for nodes 1 to 127. If it is necessary to transmit more
than 4 PDOs (more than 16 words) from one node, this node must occupy COB-IDs of other (unused)
stations. It is recommended to use the identifier of higher number stations for this purpose (127, 126, 125,
etc). The lower the used COB-ID is, the higher the priority of the messages. Thus, assigning the COB-ID of
TPDO4 from node 127 to highly important data should be avoided because all other TPDO COB-IDs have a
higher priority for transmission on the CANopen bus.
This command assigns the COB-ID of an unused TPDO of the Source Node to the defined TPDO of the local
Node. Ensure that the Source Node doesn't exist in the network or that the Source Node TPDO is
deactivated.

Hnnmm
Check that the PDO number is supported.

2. Destination Parameter Errors

If an error occurs in the Destination Parameters, the error code in the following table is stored in BFM #1001
to #1066 as diagnosis data. The "nn" part of the error code indicates Node ID, and the "mm" indicates PDO
number.
Error No. (Hex) Description
The following states are possible.
Check the Node ID and PDO number.
HFFFF • Node ID higher than 127.
• PDO number is 0.
• The parameter may have been skipped if a Source error occurred.
No response from node ID "nn" (time out).
Hnn00
Check the status of the Node ID "nn".
Previous COB-ID of destination was H80000000. RPDO was disabled. Binding was accomplished, but there
H00mm
might be an error in the RPDO mapping parameter for the destination node.*1
Node ID "nn" can not be accessed to PDO number "mm" in the communication parameter.
Hnnmm
Check the PDO number is supported.

*1. Please take care with this error message.

If the RPDO in the destination is disabled, it is uncertain whether there exists some mapping inside
the destination node for this RPDO. This node might receive the data, but it is maybe not transferred
to any I/O or data register.
When the Destination node is an FX3U-CAN, the PDO data will be mapped to a BFM (if the mapping
parameter was not changed previously). In the case of the FX3U-CAN, the error can be judged as a
warning that can be completely avoided if the mapping is done by the remote FX3U-CAN node itself.
Another possibility is to set the remote FX3U-CAN to Mode A mapping. In this case, RPDO 1 to 32
COB-IDs are different from H80000000. The disadvantage is that if all RPDO are mapped, they will
also be received. This is not really a problem, but the FX3U-CAN cycle time will be a little bit longer,
and it may be confusing if unused BFM are also changing their data values.
Note
If the local FX3U-CAN is the destination, error H00mm is disabled.

3. Other Errors
If the parameter is not set properly, the error code in the following table is stored in BFM #1001 to #1066 as
diagnosis data. The "nn" part of the error code indicates Node ID and the "mm" indicates PDO number.
Error No. (Hex) Description
Source node ID "nn" must be in the range 1 to 127, PDO number "mm" must be 1 to 4 for the source parameter
Hnnmm
and 5 to 127 for the destination parameter.

set to ON.
Refer to Subsection 5.10.1 and BFM #3000/13000 in the following table.
• To ensure that the FX3U-CAN module can handle the CANopen data in a consistent way, it is necessary to
set BFM #20 bit 0, 8 or 9 (only Virtual input mapping) to ON before reading PDO data (FROM) and after
writing PDO data (TO) to the module. 4
The data exchange control signal ensures, by internal buffer exchange, that TO data from the PLC will be

Wiring
transmitted with its corresponding PDO at the same time.
For BFM #20 bit 0, refer to Section 6.4
• To activate the CiA® 417 Lift Application Profile mode, write into BFM #21 the value K417, set BFM #22 to
K1 to store the BFM configuration and reset the Module.
• Only BFMs corresponding to the Lift Numbers for which the module is activated will be received and 5
transferred.

Introduction
The car drive controller transmits commands to the car drive unit. It receives status information from the
car drive unit and the loadmeasuring unit. If the profile position mode is used, the car drive controller needs
additional status information from the car position unit.
The car drive controller uses the Door position which is also used by the car door controller.

8.3 Virtual Input/Output Mapping

When BFM #3001 to #3003 and #12001 to #12003 are read, the virtual input mapping information is read
from BFMs. When BFM #13001 to #13003 are read, the virtual output mapping information is read from
BFMs. And when BFM #3001 to #3003 and #13001 to #13003 are written to, the virtual output mapping
information is written to BFMs.

8.3.1 Virtual input mapping

These BFMs contain the last received input data from one of the digital input panel group objects.
Receive Ring Buffer for 252 messages. The oldest data will be shown as first.
The current numbers of messages in the receive Buffer can be read from BFM #3004 or #12004.
When the receive buffer is empty, BFM #3001 to #3003 or #12001 to #12003 shows the value H0.

1. When transmitting messages

The CAN-ID, RTR/new/DLC and data bytes of each message are as follows.
1) CAN-ID
The destination of the message is specified by CAN-ID. CAN-ID is as follows, corresponding to the
function mode to be used.
For function mode, refer to Section 6.5
Function Mode Description
Store CAN-ID in the 11 bits, bit 0 to 10, in the CAN-ID n*2 LW.
11 bit CAN-ID Layer 2 Mode
In this function mode, CAN-ID n*2 HW are ignored.
Store CAN-ID in the 29 bits, bit 0 to 28, in the CAN-ID n*2 LW and CAN-ID n*2 HW.
29 bit CAN-ID Layer 2 Mode
Handle CAN-ID n*2 LW and CAN-ID n*2 HW by 32 bit instructions.

*2. The "n" corresponds to the Layer 2 message number.

2) RTR/new/DLC
RTR/new/DLC is set as follows.
High Byte/Low Byte Description
Bit 12 ON: Strict DLC check for RTR
High byte Bit 15 OFF: Send data frame
Bit 15 ON: Send RTR frame*3
Low byte Number of data bytes to transmit (K0 to K8)*3

*3. Bit 15 defines whether the message is transmitted as a data frame (Bit 15 = OFF) or a Remote
Transmit Request frame (Bit 15 = ON). Bit 12 = ON enables a strict DLC check for received RTR
frames. If Bit 12 is OFF, only the CAN-ID of an inbound RTR frame is checked for a match with a
user message; if the bit is ON, the CAN-ID and the DLC of the RTR frame must match the user
message to cause a response or BFM #1270 to #1272 flag to be set.
Bit 15 and Bit 12 cannot be set ON at the same time.
Bit 15 can be set ON if the parameter B is set to H5FFF.
Bit 12 can be set ON if the parameter B is set to H6FFF or H7FFF.
For parameter B, refer to Section 9.3
3) Data bytes
Store the data to transmit. The data length of the transmit data is set by DLC.

1. Parameter A and B for each Layer 2 message

Installation
A message buffer in BFM #100 to #393 is assigned to a Layer 2 transmit message by writing HFFFF in
parameter A, and writing H7FFF, H6FFF or H5FFF in parameter B.
When Layer 2 message number is not used, set HFFFF to both parameter A and B.

Note 4

Wiring
The Layer 2 implementation of the FX3U-CAN can handle up to 28 transmit slots with RTR handling
(parameter B = H7FFF or H6FFF). If the configuration violates this rule, the first 28 transmit message
configurations remain as they are, and RTR handling is disabled for any further transmit messages as
parameter B is forced to H5FFF.
For the RTR message reception list, refer to Section 9.4

Introduction
If the FX3U-CAN is set to Layer 2 communication mode, an incoming RTR message is indicated in the BFM if
the following conditions are satisfied:
• Matching the "CAN-ID n*1" of one of the Layer 2 messages
2
• The Layer 2 message "n*1" is configured as a transmit Layer 2 message

Specifications
• The Layer 2 message "n*1" is set to "no auto RTR response" (H6FFF)
*1. Where "n" is one of the Layer 2 messages 1 to 42.

The bits in the "RTR message reception list" are updated independently from BFM #20 bit 0.
A bit is set if a valid RTR message has been received. The bit can be evaluated by PLC program and

9.6 PLC RUN>STOP Messages

FX3U-CAN can transmit the message according to its state, if the PLC is in one of the following two states.
Up to four transmit messages can each be registered.
• If PLC state had changed to STOP from RUN, or FROM/TO Watchdog in FX3U-CAN has been timed-out
In this case, the message registered into RUN>STOP messages 1 to 4 are transmitted.

Warning
Depending on PLC Type and baud rate and bus load, FX3U-CAN may be unable to send the message. In
such a case, additional H/W and/or S/W should be considered for safe system behavior.
If possible use only one "RUN>STOP message" which will increase the possibility that the information is
transmitted in the event "RUN>STOP" occurs.
If more than one message is defined, messages are transmitted in order of priority "message 1" to "message
4".

Note

• The time differs depending on the number of I/Os and on the number and types of extension blocks.

10.7 Restore Object Dictionary Default Settings

Introduction
This command is an easy to use command for the load parameter command in the Object Dictionary Index
H1011 Sub-index H01.
The CANopen devices need to be reset after the command to make the change become effective.
Note that the NMT Master startup process uses SDO's which can be result in an Error of the CIF SDO 2
command if the NMT Startup Master accesses the remote Node at the same time.

Specifications
For the Object Dictionary Index H1011, refer to Subsection 5.6.12

Execution procedure: Restore object dictionary default settings

1) Write the target node-ID for which the object dictionary default settings are to be restored, to BFM #1001
to #1066.
3

Installation
When HFFFF is set as node-ID in BFM #1002 to #1066, the "Restore object dictionary factory default
settings" is finished.
The local FX3U-CAN can be specified by its actual node number or by using "0".
2) Write the command code H6010 to BFM #1000.
When the command code H6010 is written to BFM #1000, the command is executed.
4
3) When the Object Dictionary default settings have been restored, H6011 is written to BFM #1000.

Wiring
If H601F, H000F or HFFFF is read from BFM #1000, refer to Section 10.9
4) To activate the default settings, the device has to reboot. Do not use the "Store Object Dictionary
Settings" command between the "Restore Object Dictionary Default Settings" command and the Reset
command.
