EDD/DM User's Manual, 2.4
Chapter 6 MonitorsThis chapter covers all the monitor objects--objects whose purpose is to display the values of process variables at run-time. With them, the operator can view the current status of process variables at run-time quickly and easily. They are always dynamic and never static. They are never used for any other purpose than to monitor specified channels.
Monitors, like controllers and plots, do not take on their true appearance until they are connected to a channel at run-time. When you draw them, they appear simply as rectangles with an outline, with a label indicating which type of object they are, with their foreground and background colors, and with the name of the channel the monitor is configured to connect to at run-time. If you specified a default channel in the Display Attributes window, the default channel name will appear on this line. Thus, there are only three things a monitor displays prior to run-time: its type, its colors, and the channel you specify for it. The section on each monitor describes and illustrates its run-time appearance.
A monitor, like a controller or a plot, will turn white at run-time and display a certain message when it is not connected to a channel at run-time, for whatever reason.
