System bus management (module number: 101)
•
The process image for this SB is created in a fixed system task (interval: 1 ms).
With this SB
•
a Reset Node can be activated to accept, for instance, changes in the baud rate and
address assignments.
•
a Communication Error and Bus Off State can be processed in the PLC-program.
•
the transmission time of CAN2_OUT and CAN3_OUT can be influenced.

CAN_bResetNode_b function
A reset node is activated by setting C0358 = 1 or
CAN_bResetNode_b = TRUE.
Tip!
Even if the CAN_Management SB has not been assigned to the control configuration, code C0358
can be used to activate a reset node.

CAN_bTxCan2Syncronized_b / CAN_bTxCan3Syncronized_b function
•
FALSE : Data from CAN2_OUT/CAN3_OUT are transmitted at the end of the process image.
•
TRUE : Data from CAN2_OUT/CAN3_OUT are transmitted after Sync.
– Via C0367/C0368 you can set the identifiers for the Sync transmit and receive telegram.
– The
Sync Tx Time can be set via C0369.
– Detailed information about this can be found in the description for the
CAN_Synchronization SB.
