2.13 Job server
2.13.1 General
ADDM offers the user the use of a job server in the Client-Server application.
ADDM can automatically compare the data of the components of an ADDM project
at defined times via the job server. ADDM can create a safety backup if a
comparison reveals a difference.

Fig. 2-8: Job server
The Job list containing the desired Jobs is created via the clients. When the time
entered has been reached, the Job server gives the client the Job which has to be
done. The actual Job is performed by the client. The client reports the result of the
Job to the Job server. Depending upon the type of Job, the Job server now order
the client to take actions.
If an operator panel (OP) of the control is used as the ADDM client, the data of the
control (e.g. NCU) can be compared with the data backed up on the server without
further operator action. The Job server can order the client to make a "safety
backup" if a difference is found between the online and offline data. The client
creates this backup.
