See the steps to follow in this FAQ: How can you have system error messages from a SIMATIC S7-300 / 400 displayed in WinCC flexible? Hope this helps, Daniel Chartier

Have a look at it anyway. Hope it helps, Daniel Chartier

Per Olof Posts: 311 Rating: (3)	Thanks dachartier! With "Report System Error function" you can get also the led status ? and if the PLC is in run/stop mode ? I have not STEP 7 at home so I can not check now. How to check if the PLC are in run/stop mode ?
