6.3Viewing PV and SP in a Graph

The CN8-SW system allows operators to display a trend graph showing any controllerÕs SP and PV in real-time.

To view the real-time trend graph:

1.While logged in as MULTI (or another user with Controller Configuration privileges), select the controller by clicking on its image in the main graphic display. The border of the controller will be highlighted.

2.Select Controller Graph. The trend graph will be displayed.

Initially the graph will not show any trend tracings. However, as soon as the selected controller is polled by the CN8-SW system, trend tracings will begin to be drawn. As long as the Graph Window remains open, the trend tracings will be updated.

To close the Graph Window, double-click on the X in the top right corner.
