Precondition: RIOforFA profile is not activated (F-Parameter F_Passivation = 0, symbolic value "Device/Module").

Set the F-Host input OAD_Nec_C = TRUE (OperatorAcknowledgeDevicefault_Necessary).
"Reaction on Device_Fault" is activated.
Behavior with OAD_Nec_C = TRUE ("Reaction on Device_Fault" is activated):
In case the F-Host or an F-Device detects a F-(Sub)Module error (Device_Fault = TRUE), fail-safe values will be activated until the error is cleared and acknowledged. The F-Host then sets the output OA_Req_S (= TRUE) as soon as the error has been eliminated and operator acknowledgment is possible. As soon as it is acknowledged (OA_C = TRUE) the F-Host driver will reset the request variable OA_Req_S (= FALSE).
Behavior with OAD_Nec_C = FALSE ("Reaction on Device_Fault" is not activated):
In case the F-Host or an F-Device detects a F-(Sub)Module error (Device_Fault = TRUE), fail-safe values will be activated until the error is cleared. Acknowledgement is not needed.⮫ “Avoid unintended behavior”
