Hi all

My customer Site having a Schneider PLC M340-20 with 2 Remote IO by using STBNIP2212 via ethernet TCP/IP.
My question is if any of my remote IO disconnected from main PLC, the main PLC would like have a signal address (or maybe a signal bit) to indicate that the remote IO is disconnected.
Any idea how to do it?

Appreciate your reply.:geek:

thank you.
 
How are you reading the STB ? READ_VAR or I/O Scanning ?

In either case there is management words available to tell you if the remote I/O has been read correctley
 
Thanks for reply

I am using I/O scanning for remote IO connection.
May i know the which management words available? Thank you
