8.4 FIF_CAN_Management (node number: 111)
By means of this SB
· a reset node can be activated, e. g. to accept changes with regard to the baud rate and
addressings.
· Communication error, Bus−off state, and further states can be processed in the PLC
program.
· the instant of transmission of FIF−CAN2_OUT and FIF−CAN3_OUT can be influenced.
