To configure a UniStream Built-in, PLC (USC) series controllers, and USL (USL5/USL7/USL10) displays, to act as a VNC Client:
In the Solution Explorer navigate to PLC Communications > Protocols > VNC Clients.
The following options are available:
Disable cursor (override server configuration): Select to disable visible pointer control and touch input functionality.
Auto Reconnect: Edit the timeout if required.
Force H264 Decoding: Select to enable H.264 decoding for the connection. When enabled, the PLC connects only to VNC Servers that transmit H.264; if the server does not use H.264, the connection will not succeed - clear this option to connect to such servers. There is no automatic fallback.
