Reagarding reading of values from energy meter using MODBUSRTU protocol in panasonic PLC

I was trying to communicate an digital energy meter with Panasonic AFPXC14R PLC using modbus rtu protocol but i’m unable to read the values into the plc.When i used an open software MODBUSPOLL for reading the values of meter i could read the values.But i’m unable to read values into the plc.The address of the energy meter are 40108,40109. Could you please help me with the programming to read the values into plc,as i’m working on my MASTERS Project and i’m struck with this.
