Communication between DIAView SCADA and Delta PLC—DVP 12SE through Modbus serial port

Communication between  DIAView SCADA and Delta PLC—DVP 12SE through Modbus serial port

The DIAView software supports communicating with devices through the serial port (RTU and ASCII) based on the Modbus communication protocol standard.

Supported devices includes:
 • Modicon Modbus RTU
• Modicon Modbus ASCII
• Delta DVP RTU
• Delta DVP ASCII
• Delta AH RTU
• Delta AH ASCII
 
Example of configuring the DIAView software to perform IO communication with devices through the serial port connection is as follows:

Creating a communication between the DIAView SCADA and Delta PLC—DVP 12SE through serial port

Example 1: Using the “Delta DVP ASCII” driver

 
Step 1: Create the following hardware architecture and set the 12SE COM2 communication port parameters as 9600,7,E,1,ASCII, station 1, as shown in the figure below:

  Step 2:
Right-click on the
IO communication node in the tree index of the project window and select “Add device”; the menu selection in the figure below will appear:
 
  Step 3: Select Delta DVP Delta DVP ASCII in the Driver Selection” window, as shown in the figure below: 
  Step 4:
Configure the Delta DVP ASCII communication parameters, as shown in the figure below:

 

Step 5: Click
the button to the right of
Basic”→ Serial port and open the Serial port parameter setting” window, as shown in the figure below:
  
  Step 6: Set the
serial port communication parameters:
9600,7,E,1,ASCII and set the communication port as COM1 (you can see that the detected currently assigned serial communication port is COM1 in device manager), as shown in the figure below:
   Step 7: Configure the serial port communication parameters and then click the “OK” button to return to the Delta DVP ASCII communication parameter configuration window. 
Set the communication and troubleshooting parameters. The “Device address” must be the same as the PLC station number, therefore set it as “1”.Preset values can be used for the other options, as shown in the figure below:
 
 
   Step 8: Click
the
OK button when all parameters have been
configured and the device with the preset name will appear under the “IO
communication” node of the project tree index, as shown in the figure below:
 
 
Step 9: Rename
the added IO communication device to
Serial port device and then the serial port driver communication configuration is complete, as shown in the figure below:
