# ID 280603

Response for non commanded step.
Description | The PLC sent an acknowledgement for which no job can be found. This error occurs when external (slave) software communicates incorrectly with the GCM. Basically, the GCM sends a request containing GCM-specific data to the slave. The data must be returned in the response to determine the associated master job. If this data is missing, the message is rejected and the error message is generated.

If the message does not belong to a pending master job, it may be that it is not terminated.
