Delta HMI to PLC Modbus Communication Network

Setting Up Communication between ScreenEditor and WPLSoft :-

To set Up the communication we need to define some of the Communication Parameters both at PLC and HMI side. Open the WPL SOft and select a new project , To set up the Modbus Communication open the communication Wizard and define the Data Length as 8, Parity as None and stop bit as 2 , baud rate as 9600 BPS. Also define the slave address as 1 for first PLC and 2 for second and 3 for third. Rest all parameters will be same for other PLC also.

We have to define the same communication parameters at the HMI side. Open the Screen Editor and select the HMI model and in the Base Port controller select as Delta Controller ASCII. After this go to Option --> Configuration and select the Com Port 2 and Define the same communication settings as we did at PLC Side.
