CANopen Sync mode |
Sync Bus only |
Sync Bus only |
The “CANopen Manager” sends SYNC messages to “CAN bus” only. The properties of the sync message are configured in the “CANopen Manager” parameters. |
|
Sync Bus and task |
The “CANopen Manager” sends SYNC messages to “CAN bus” and triggers an IEC task. |
The “CAN Bus” tab contains the basic CAN bus settings and special settings for the CAN 2.0 B protocol.
The settings in “29 Bit COB-ID” are valid only for the CAN 2.0 B protocol. Ensure that the “Enable 29 Bit COB-ID” option is enabled. Otherwise, CAN 2.0 B frames cannot be received. The other parameters in “Enable 29 Bit COB-ID” configure the receive filter.
SAE J1939
An example project for the SAE J1939 protocol in PLCs is provided in the application example ⮫ AC500 SAE J1939 protocol.

|
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 with one node does not affect other nodes. The manager tries to reestablish the communication with the affected nodes. |
|
Enabled |
If this function is enabled, the manager also stops the communication with all responding and active nodes. |
||
|
Send “Global Start Node” |
Enabled |
Disabled |
No “Global Start Node” message is sent after configuring the nodes. |
|

29 bit |
Specifies the bits of a CAN ID 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 that must be set to pass the filter. Only the bits set in the acceptance mask are relevant. |
