Graph Display

The operation of each CIP programme can be displayed as a graph, with analogue signals, e.g. Temperature, Conductivity, etc. being over laid with digital signals, e.g. operation of pumps, valves, etc., Graphs can be enlarged (Zoom) for more detailed examination.

For clarity, all signals can be displayed in separate colours to suit the viewer. This is achieved using the graph Settings menu at the top of the graph.

A vertical time line (red) can be moved to identify both real-time (green) and elapsed time (red) when specific operations were commenced or terminated.

All signals (analogue & digital) can be switched on/off independently to minimise information being displayed at any one time.

At the bottom of the graph display, the value of each analogue signal is shown. The values of these signals will change relative to the position of the vertical time line. The analogue signal value will continue to be shown even if the actual signal trend line has been switch-off, (from being displayed in the current graph). Each Analogue Signal can be re-scaled to enlarge the displayed data.
