Configuration of the communication module

Click menu “Tools Options” and select “Device editor” in the “Options” window.
Enable first checkbox “Show generic device configuration views” and click [OK].

Append a CM598-CAN

Right-click on your desired Slot below node “Extension_Bus” and click “Add object”.

Dialog “Replace object:” appears.
Click “CM598_CAN” in the list and click [Replace object].
Double-click “CM598_CAN (CM598-CAN)” to get the “CM598-CAN Parameters” in the editor window.

The following parameters are available:

Parameter	Default value	Value	Description
Run on config fault	No	No	In case of a configuration error, the user program is not started.
Run on config fault	No	Yes	The user program is started independent of a faulty configuration of the CM598-CAN communication module.
CANopen Sync mode	Sync Bus only	Sync Bus only	The “CANopen Manager” sends sync messages (if enabled) to CAN bus only. The properties of the sync message are configured in the “CANopen Manager” parameters.
CANopen Sync mode	Sync Bus only	Sync Bus and task	“CANopen Manager” sends sync messages to CAN bus and triggers IEC task. ⮫ “Configuration of SYNC task”

The tab “CAN Bus” contains the basic settings of the CAN bus and special settings for the CAN 2.0 B protocol.

The settings at “29 Bit COB-ID” are only valid for CAN 2.0 B protocol. Ensure the option “Enable 29 Bit COB-ID” is enabled. Otherwise no CAN 2.0 B frames can be received. With the other parameters at “Enable 29 Bit COB-ID” the receive filter is configured.

SAE J1939

An example project which demonstrates using and handling the SAE J1939 protocol in PLCs is given in the application example ‎⮫ AC500 SAE J1939 protocol.

Parameter	Default value	Value	Description
Bus parameters
Transmission rate	250 kBit/s	10 kBit/s 20 kBit/s 50 kBit/s 100 kBit/s 125 kBit/s 250 kBit/s 500 kBit/s 800 kBit/s 1000 kBit/s	Transmission speed in [kBit/s]
Node settings
Stop in case of monitoring error	Disabled	Disabled	The manager does not stop in case of a monitoring error (Node Guarding or Heartbeat Error). A loss of communication to one node has no influence to other nodes. The manager tries to reestablish the communication to the error affected nodes.
Stop in case of monitoring error	Disabled	Enabled	If this function is enabled, the manager will also stop the communication to all responding and active nodes.
Send “Global Start Node”	Enabled	Disabled	No “Global Start Node” message is sent after configuring the nodes.
Send “Global Start Node”	Enabled	Enabled	A “Global Start Node” message is sent after configuring the nodes. This synchronize all nodes again.
29 Bit COB-ID
Enable 29 bit COB-ID	Disabled	Disabled	29 bit CAN-IDs are disabled, but 11 bit CAN-IDs are still enabled.
Enable 29 bit COB-ID	Disabled	Enabled	29 bit CAN-IDs are additional enabled.
Acceptance mask	0	29 bit	Specifies the bits of a CAN-ID which will be evaluated by the filter. For instance, with an acceptance mask = 0x1FFFFFFF all bits are evaluated.
Acceptance code	0	29 bit	Specifies the bits of a CAN-ID which has to be set to pass the filter. Only those bits which are set in the acceptance mask are relevant.

The tab “CM598-CAN I/O Mapping” contains bus cycle option used for CANopen configuration. The following parameters are available:

Parameter	Default value	Value	Description
Bus cycle task	Use parent bus cycle setting	Use parent bus cycle settings	Settings from “PLC settings” tab are used.
Bus cycle task	Use parent bus cycle setting	Task	Name of the task that triggers the bus cycle

The tab “CM598-CAN IEC Objects” contains the created instance of the IO driver.
