with different IP Address and/or Safety Network Number (SNN)
already owns inputs of the CIP Safety Adapter. The IP Address
and SNN of the current owner are written to Non Volatile
Memory of the CIP Safety Adapter.
Consequences
An external CIP Safety Scanner will not be able to connect and
write signals to the CIP Safety Adapter of the Robot Controller.
Probable causes
The IP Address and/or SNN of the external CIP Safety Scanner
has changed. The inputs of this CIP Safety Adapter is already
owned by another external CIP Safety Scanner.
Recommended actions
Verify that the IP Address and SNN of the external CIP Safety
Scanner is as intended. Reset CIP Safety to clear the ownership
from Non Volatile Memory of the CIP Safety Adapter.

Description
The arg is in Operator Acknowledge state.
The PROFIsafe host is waiting for operator acknowledgement.
Consequences
arg is sending fail-safe values.
Probable causes
