UniStream Display

UniStream Display panels are resistive color touch-screens that support VNC client, and are available in different dimensions.

In addition to HMI screens, Displays support UniApps, a built-in system that enables the user to access communication settings, and manage the device.

These displays are suitable for use with UniStream PLCs. The factory default IP addresses are given below.

To enable VNC Server on a UniStream Controller and set Passwords via UniLogic, click Passwords on the Solution Explorer.

Note that you can also apply a password via UniApps that will be saved to the PLC as described below.

Defining VNC Settings

After the panel is powered on, select the Network tab at the bottom of the screen.
Enter the IP Address for the VNC connection, a password if one is required by the VNC server, edit the timeout if required, and then tap Apply.

To add connections, tap the Connection scroller and repeat the steps above.

When a connection is defined, the Connect button is activated; tap it to initiate the VNC connection.

With Exit

Selecting the With Exit option places an Exit VNC button on screen during a VNC session. This can be tapped in order to exit to UniApps.

Apply a Password via UniApps

To apply a password via UniApps that will be saved to the PLC as described select the System> Password, and use the displayed options.

Note that via UniApps, you can enable UniStream to register when a connected VNC client screen is touched; this allows the use of UAC with idle time and screen saver. To implement this feature, in UniApps, access the Network tab-> VNC Server -> Set 'touch bit'". Press the General.Touched check box and press apply. The VNC server will restart with the "touch" identification option.
