EDD/DM User's Manual, 2.4

Chapter 7 Controllers

This chapter describes all the objects found in the controller menu (Figure 7-1). Controller objects are the objects used to manipulate the values of process variables. Actually, not all controller objects manipulate values--the related display callup, execute script, kill display, print display, and print options objects-- do not manipulate values. However, since they do perform run-time operations and since they are in the same menu, they have been lumped into the controller subclass.

The run-time behavior of controllers is much more complex for controllers than it is for monitors, simply because you can input values through the keyboard or mouse; however, this chapter will not discuss how to input values--it will not discuss how to actually use these objects at run-time. To find out how to actually use controllers to control process variables, see Chapter 9, DM: Run-time Operation, which discusses all aspects of run-time behavior in DM. This chapter merely describes how to configure controller objects and only those aspects of run-time behavior that you need to know in order to configure them.
