Delta PLC modbus RTU communication

I would like you to help me with my issue, I have about 50 modbus rtu sensors connected together with a daisy chain topology, and I would like to read the registers continuously and store the values of each register in delta plc memory and for this purpose I have selected DVP ES2   which has two communication interface, through COM3 I would like to collect data from modbus sensors on the rs485 bus and through COM2 I would like to read data from PLC memory to my SCADA software which supports MODBUS RTU driver over serial connection.
