Tasks

Create a task to schedule when programs execute. Schedule a task to run continuously, periodically, or when triggered by a specific event. A program executes a set of instructions in a project. Create tasks from the

Execution

explorer, by either right-clicking on the controller or

Tasks

folder and selecting

New Task

Creating a task varies by task type. Task types include:

Continuous. A continuous task runs continuously in the background through all assigned programs. CPU times not allocated to other operations scan the assigned programs. After the continuous task scans a program, an output update triggers and the task scans the next program.

Periodic. Periodic tasks perform a function at a specific rate. Multiple periodic tasks may exist where each task is operates at independent rates.

Event. Event tasks perform a specific function that is triggered by a specified event.

Create up to 1000 tasks.
