AC500 - CP400 retain values problem
I am trying make my program retain values when there is a power off. I use pm556eth plc and cp400 touch panel. I have tried changing my modbus register from %m to %r and i've changed my Com1 modbus interface server setting to use %R area. I also changed the cpu end persistent parameter to 1023. After i have made these changes my program started to retain values after a power off but touch panel gives an error because of those %R registers. Error says "unrecognized response" and also the program doesnt seem to work properly but i'm not sure.
What should i do to solve these problems?
