Read 1200 error CPU from HMI

Hi, 

Pls advise how to read if the CPU (1214C v.2.2) got into Error state on HMI panel ?

Thanks

Hello eam_rts,

this FAQ might help you:

• "How do you monitor communication between CPU and panel in TIA Portal V13 SP1?"

  "Here we explain how to use an area pointer to configure connection monitoring of the panel via the CPU in the TIA Portal V13 SP1. We also show how to have the current status of the CPU visualized."

Here is another one, but I don't think it works when the PLC doesn't run.

• "System Diagnostics View using WinCC (TIA Portal) and SIMATIC Comfort Panels"

Haven't tested it, but maybe you can try what NKrir did: Use the "LED" block in the PLC to read the status of the error LED of the PLC. Well, I'd say it depends on the kind of error...
