State Description
Safe (Module passiv- PROFIsafe communication is up and running.
ation & reintegration) Safe stopping function (eg. SS1) has been performed to the end. This may have been
caused due to safe stopping request.
As soon as the associated safe stopping function has been completed and possible re-
quests for it removed, reintegration of the module is possible.
PROFIsafe Control Byte bits in the F-Host to the FSPS-21 module:
• "activate_FV" = 0
PROFIsafe Status Byte bits from the module to the F-Host:
• "WD_Timeout" and "CE_CRC" = 0
ABB_PS3 profile bits from the module to the F-Host:
• device_state = 1
Note:
Reintegration may be so fast that the device_state-bit may not be updated to Safety
PLC.
Safe (Module passiv- The application is running and there has been an error in the PROFIsafe communication.
ation) STO is activated.
Possible reasons for module passivation are:
PROFIsafe communication failure (CRC error) or PROFIsafe watchdog timeout exceeded.
If the PROFIsafe communication is broken, the safety application continuously attempts
to establish a communication to the safety PLC.
A state transition to another state is possible only if the detected error has been solved.
