Create and configure a new periodic task

The ControlLogix PID function block uses an algorithm that needs a defined

time period of operation, so a Periodic Task needs to be created.

1. Right-click Task, and select New Task.

The New Task window opens.

2. Enter >Pressure< for the Name and 1000 (ms) for the Period.

The reason for 1000 (ms) scheduling is that PID loops generally do not

require fast executions.

3. Click OK.

Pressure is added to the Tasks.
