When using PROFIsafe as safety bus:
ƒ If faults occur in the PROFIsafe communication, the data is passivated by the
PROFIsafe driver.
ƒ After the PROFIsafe communication is reinitialised, the drive is automatically
enabled again if no standstill function is selected.
ƒ Events which cause an error status are sent as diagnostic telegram via the safety
bus.
