Chapter 6 – Task Management
An integral part of the MAPware-7000 software is the ability to create tasks. Tasks are
specifically predefined actions taken by the controller such as writing a value to a tag register,
displaying a new screen, turning a bit on/off, etc.
The number of tasks is limited only by the total amount of memory available in the controller.
Each task has two fundamental components: the action taken when the task activates and the
triggering mechanism that starts the action.
