System bus management FIF CAN (module number: 111)
• 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 FIF-CAN2_OUT and FIF-CAN3_OUT can be influenced.

Function FIF_CAN_bResetNode_b
A reset node is activated by setting C2458 = 1 or
FIF_CAN_bResetNode_b =TRUE.
Tip!
Even if the FIF_CAN_Management SB has not been assigned to the control configuration, code
C2458 can be used to activate a reset node. (^ 5-7)
Function FIF_CAN_bTxCan2Syncronized_b / FIF_CAN_bTxCan3Syncronized_b
• FALSE: Data from FIF-CAN2_OUT/FIF-CAN3_OUT are transmitted at the end of the process
image.
• TRUE: Data from FIF-CAN2_OUT/FIF-CAN3_OUT are transmitted after Sync.
– Via C2467/C2468 you can set the identifiers for the Sync transmit and receive telegram.
– The
Sync Tx time can be set via C2469.
