Hi,
I am trying to communicate modicon M340 PLC with an Schneider T200 Remote main unit controller over modbus TCP. the PLC has got in built Ethernet port. the modbus register I would like to read has address 341 Hex. I am bit confused how I am gonna used the READ_VAR instruction to read this register from T200 unit. Please let me know it's bit urgent
 
Example of reading address 341 hex from device with IP 192.168.1.12:
