I am trying to communicate with ENERCON CONZERV ENERGY METER EM6434 having RS485 2 wire connection using SCHNEIDER TWIDO PLC and RS485 card inserted in port 2. Energy meter memory words are of float type, so instead of %MW I am using %MF for Modbus program in PLC but with this no communication is happening. Instead if I use %MWs and starting address as 4001, I am getting some response in the reception table, only slave ID and number of bytes to read.
Please guide me to achieve the communication.
