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.
– Click Run Continue Task when there is no communication or
background tasks to process; controller immediately returns to the
continuous task.
– Click Reserve for System Task to 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 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.
