Hello

Look at What identification data can I read out of SIMATIC S7 CPUs?

Hope this will help you!

regards

Hello

Another easier way How can you report S7 system errors in WinCC? You can also use link from my previous post to read diagnostic buffer on CPU. Put in search "CPU events read" and you'll find how...

regards

Thanks man,

i followed that link and i found it very useful....

but after i created the s7 project and integrated it with wincc, no messages are displayed in runtime

all i want is to display the cpu status (stop or run)
and display a programming error (such as error in conversion from BCD to Integer) in WinCC runtime...

what configuration parameters of (Report System Error) dialog must be selected?

I have a step by step document for creating Report System Error and transfering to WinCC. The pdf is 600K so I can't upload it but I can send it to you if you provide me with your email address.

Also here is code using SFC51 to extract the system status for a run bit and a stop bit that can be converted to tags in WinCC
