The settings are only accepted after carrying out one of the following actions:
ƒ Renewed switch−on of the 24 V low−voltage supply
ƒ Reset node via the bus system (by the network management (NMT))
ƒ Variable CAN_bResetNode_b or CANaux_bResetNode_b = TRUE
ƒ Reset node with C0358/2458 = 1
Note!
If reset node is executed via GDC, communication will be interrupted. You
therefore have to log in again manually or find the devices connected to the
bus once again (fieldbus scan).
