DELTA DVP-20SX PLC to Wonderware Intouch

Anyone knows how to communicate Delta DVP-20SX PLC to Wonderware Intouch using ethernet (MBENET)/modbus ethernet? Using this I/O server MBENET, i am able to link the discrete i/o such as X (digital inputs), Y(digital output) & M (internal i/o). However, i cannot do it for Data Memory (holding registers). Please help me. Thanks

You can use modbus ascii table holding and data registers for read or write the data registers
