Preparations in the S7

The use of the PDiag process diagnosis needs an according expansion of the Simatic Manager. With the object properties monitorings can be defined in the Simatic Manager.

At the moment the control system supports the monitoring types Address Monitoring and General Monitoring.

After the configuration of the process diagnosis in the Simatic Manager a PDiag translation run has to be started. The translation run assigns a message number to each message. This message number serves a offset address for the control system variable from the type Alarm-S.

Info

The message numbers are generated automatically by the PDiag program. Each translation run can result in new numbers. Thus after each translation run the variables in the control system have to be adapted.
