 Bigger Bigger  Smaller Smaller  Reset Reset

I have a power analyzer from the Schneider-Electric company and I would like to communicate with it through modbus connection.
I have also arduino Duelminove.
I tried so many modbus programs but unfortunately I cannot connect to the device.
In the link http://download.schneider-electric.com/files?L=en&p=&p_docId=&p_docId=&p_Reference=S1B46607&p_EnDocType=Instruction%20sheet&p_File_Id=25550748&p_File_Name=S1B46607-01.pdf you can find more information about the device.
Can anyone help me about the correct program that I can use?

Thank you

And what problem do you have with it? Is it modbus RTU/RS-485 device? May be it doesn't use CRC. Have you tried to connect with MBtest and read registers?
