• Context?sensitive diagnostics initiation due to process error message
• Output of the operands with symbols and comment Switch?over capability between LAD, STL and signal list
• Supporting fault rectification by means of direct process access when using the motion view
• Output of the faulty operands directly in the alarm including address, symbol and comment
• Consistency test in runtime: Inconsistent diagnostics units are marked with icons.
  This permits quick locating of faults regarding configured data in the commissioning phase.
• Direct, unit?related entry point in the diagnostics view from user displays (by using ProAgent functions)
• Unit or alarm?related entry to STEP 7, e.g. LAD/STL/FBD editor, S7 GRAPH, HW CONFIG upon system error messages, is supported fully automatically
• S7 GRAPH OCX for the graphical display of step sequences (overview display)

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 WinCC/SIMOCRANE CMS and the special process diagnostics option package SIMATIC ProAgent, it is possible to design a powerful system to:

• Display errors in a user?defined text
• Display the cause signal (criteria analysis) at the link level
• Clear process errors

S7 PDIAG offers the following functions:

• Configuration for detection of process faults:
• S7 PDIAG permits definition of signal monitoring (including criteria analysis) and the associated message texts within the LAD/CSF/IL editor.
• Configured FB call (optional) on diagnostics event
• Online modification of monitoring times supporting troubleshooting
• In addition to the display and detection of process faults, S7 PDIAG and ProAgent provide the user with the facility to control or modify movements and operating modes directly from the HMI display unit.
