Read Siemens SF (System Fault) signal

[AlecTek]

Hi all, my MP377 connect to ET200S, let's say that a 2/4 RTD module on ET200S has input addresses 512-519, and it has a SF LED which is blinking. From where (or what address) can I read the SF status so I can display it on my MP377 screen?

Thanks for any help.

so what CPU?

Using an S7 cpu- the easiest setup is RSE (report system errors) this will automatically display hw messages...etc

Thanks. I'm using Multipanel MP377, which connect to ET200s through profibus. In fact, I am not worrying about the errors, I just want to display there is an error, is there an address which contains all the modules status?
