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:
