CP1L-EM30DR-D connect E5EC via RS485

1 post in this topic

Hi.. I'm trying to connect CP1L-EM with Temperature Control E5EC and a motor heater. 

I already set the temp. Control for modbus comm, I used the FB lib but I can't read PV, SV and write SV. Is there a specific address for the trigger bit and normal end bit c, Etc? 


Thank you all and hoping find a solution for it.
