Sometimes there is a need to access a remote PLC or other equipment with an RS-485 or RS-232 interface. To solve this problem, you can use the Virtual UART function which is built into WebHMI.

Suppose that we need to update the program in the controller Delta DVP-10SX. It is connected to WebHMI using RS-485.

1. Open the connection settings and change Mode c Normal to Virtual UART.
