Hello. I have a S7 400H system and CP443-1 in my project..Right now am in the middle of the commissioning. In my site we have a Schneider PLC M241 which acts as a modbus server.. i need to read data from Schneider PLC to my PLc via CP443-1. Schneider people prepared modbus mapping and their starting address is 460201(reading holding register).when i tried to access this address via our Modbus block MB_REDCL i am getting error. But the same register can be read from Modscan software.. In our MB_REDCL block information shows that i can access registers from 0-65565.. But the Schneider PLc address lies with this range and still i cannot read the data.can anyone help me out this one.. ------------------------------------------------------------------------------------------ |
