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.
4.8.2 Logbook
Error states are saved in the logbook of the standard device. The following is entered:
ƒ Type of response (e.g. trouble, warning, or information) to the event
ƒ Module which has caused the event (e.g. MCTRL or TEMPCONTROL)
ƒ Date/time (in case of memory module with real−time clock)
ƒ Value of the power−on time meter
The available logbook entries can be displayed in the »Engineer« when an online
connection has been established.
