FC call interface of the FCs AG_SEND or AG_RECV again after the FC has
confirmed job execution with DONE=1 or ERROR=1.
If this is ignored, it is possible that the execution of the job will be aborted with an
error and resources could be permanently occupied on the CPU.

When using SFB54, the optional fields “Vendor ID” and “Instance ID” are not

should remember this when evaluating the data.
