PLC Download

Through the V-NET PC software, remotely pass-through the V-BOX or IIoT ig screen (the PLC remote download procedure is the same)  to directly control the PLC devices, including upload, download, and monitor PLC programs.

COM port

When installing the software for the first time, users need to restart the computer to prevent the virtual serial port node from being incorrect. PLC software may not be able to identify the virtual serial port. After the software is successfully installed, the virtual serial port is displayed in device Manager, as shown below.

Remote download configuration

When operating pass-through, V-BOX and IG screen should be connected to the network, and ensure normal communication with PLC.

If the virtual serial port is set successfully, the system automatically updates the enabled virtual serial port. Fill in the device information, choose COM1 or COM2 as the communication port. When the information filled in is the same as the PLC, Click the button 9.4.png

If the pass-through succeeds, the current status changes to "running", and all the filling information becomes gray and could not be filled, and only the function button "stop" is left indicating that the pass-through is successful.

  2. Edit. Users could add and save different pass-through parameters configurations.
  3. Name. Set the name of the saved record.
  4. Communication port. The communication ports of V-BOX and the device to pass-through
  5. Virtual port. The virtual serial port is generated by the PC. After successful penetration, the PLC software connects to the virtual serial port, and then the PLC could be monitored, uploaded/downloaded, etc.
  6. Connection ways include RS232, RS422, RS485, and Ethernet.
