PROFIsafe communication is up and running. The safety application is running without any errors but waits
for the acknowledgment of a module reintegration (module error is gone).
The fail-safe value “0” is still transferred to the Safety CPU for all passivated input channels. All passivated
output channels have a state of “0”. The PROFIsafe diagnostic bits for all channels have the state of “0” to
indicate that fail-safe values are transferred.
The OA_Req_S bit is reported as “1”.
As soon as the safety application of the Safety CPU sets OA_C (positive edge), the Safety I/O module goes
to RUN (ok) state if no further errors are detected. One has to send the positive edge to the Safety I/O
module until OA_Req_S starts delivering “0”.
PROFIsafe status bits in the F-Host for Safety I/O module:
OA_Req_S = 1
FV_activated_S = 1
Device_Fault = 0
Process data bits in the Safety I/O module process image:
PROFIsafe diagnostic bit = 0
Channel process value = 0
Reintegration request bit = 0
