IP Address

The IP Address field specifies the network address of the target PLC that the PLCVISU HMI should connect to—for example, 192.168.1.25. This allows the system to establish a direct WebSocket connection to retrieve live data from the backend.

Alternatively, you can use the special placeholder value "eth" in this field. When set to "eth", the IP address will be automatically resolved based on the active network interface of the current PLCVisu instance (i.e. the machine running the webserver). This is especially useful in development or multi-device environments where the target address may vary or needs to be dynamically detected.
