Using the Vision Control

Vision control icon Use the Vision control to display a CygNet Vision screen through FMS Explorer. You can select any previously constructed CygNet Vision screen and display it through the FMS Vision control, to view SCADA or other data alongside your measurement data. You can create up to eight instances of this control.

CygNet Vision screens are created using CygNet Studio, and must exist before they can be viewed from the FMS Explorer Vision control. You cannot create the screens through FMS Explorer. See CygNet Studio for more information about creating screens.

Note: Currently, CygNet Vision hyperlinks are not supported in FMS Explorer. All other CygNet Vision functionality is available.

The Chooser and Options panes are not necessary for this control.
