Configure the System Overhead Time Slice
To configure the system overhead time slice, perform this procedure.
1. In the Controller Organizer, right-click the controller and choose
Properties.
The Controller Properties dialog box appears.
2. Click the Advanced tab.
3. Enter a numeric value in the System Overhead Time Slice box.
4. Use Run Continuous Task (default) or Reserve for System Tasks.
•
The Run Continue Task radio button is used when there is no
communication or background tasks to process; controller immediately
returns to the continuous task.
• The Reserve for System Task radio button allocates the entire 1 ms of
the system overhead time slice whether the controller has
communication or background tasks to perform before returning back
to the continuous task. This option lets you simulate a communication
load on the controller during design and programming before HMIs,
controller to controller messaging, and so forth, are configured.
5. Click OK.
