I have replaced a Schneider Premium PLC with a M580, I have Intouch SCADA 2014R2SP1 with OI-MBTCP G.1. I have done this several times before without problems. But when I did this today Input registers do not work, Holding registers work.

Must be some incompatibility between the new M580 CPU (firmware SV03.20) and the OI-server, or maybe incorrect configuration?
I have tried to alter block I/O size.

Any quick fix? (I don´t have time to upgrade intouch)

Regards

 

Solved

I changed Input registers to Holding registers and now communication is working fine.
Maybe not an optimal solution, anyway, customer is happy...

If you have any idea why input register stopped working, please let me know.

Kind Regards

I just did a simple test in Kepware. Do not have Aveva IO server running. Works.
