Communication monitoring (CE1 ... CE4, node guarding)
Monitoring times (C0357)
Each process data input object is able to monitor if a telegram has been received within the
set time. As soon as a telegram has been received, the corresponding monitoring time
(C0357) is restarted.
If no telegram is received within the set time,
ƒ
TRIP "CE1" (CAN1_IN, cyclic (sync−controlled)),
ƒ
TRIP "CE2" (CAN2_IN, reserved) or
ƒ
TRIP "CE3" (CAN3_IN, event−controlled/cyclic without sync) enabled.
When C0357 = 0 ms (Lenze setting) this monitoring function is switched off.

Bus−off (C0595)
If the power supply module is disconnected from the system bus (CAN) due to faulty
telegrams, the "BusOffState" signal is set and TRIP "CE4" is enabled.
The monitoring can be deactivated with C0595 = 3.
