Modul number: 101
• The process image is created in a fixed system task (interval: 1 msec).
With this SB
• a Reset-Node can be activated.
(Changes to the baud rate and the addressing only become effective after a reset-node.)
• a Communication Error and Bus Off State can be processed in the PLC-program.
• the transmission time ( Sync Tx Time )can be modified.

Function CAN_bResetNode_b
A reset-node is atcivated by setting C0358 = 1 or
CAN_bResetNode_b switches immediately =
TRUE.
Tip!
Even if the SB has not been assigned to the control configuration, code C0358 can still be used to
activate a reset-node.
