SIMATIC S7-PDIAG increases the availability of machines and production plants and provides optimal support to personnel for on-site fault analysis and correction.

S7-PDIAG supports the configuring of process diagnostics for SIMATIC with the LAD, FBD or IL programming languages. Using process diagnostics it is possible to recognize faulty states outside the automation system (such as limit switch not reached).

In conjunction with SIMATIC HMI display units and the special process diagnostics option package SIMATIC ProAgent, it is possible to design a powerful system:

• To display errors in user-defined text
• To display the cause signal (criteria analysis) at link level
• To clear process errors
