You can use the Modbus RTU code here when using CP1H and MODTCP61 as a master (client). http://forums.mrplc.com/index.php?app=downloads&showfile=867 The MODTCP61 is sent Modbus RTU commands from the PLC. It turns the Modbus RTU Node Number into the last octet of the target devices IP Address. As far as your specific energy meter, I have no experience.
