Interrupt the Execution of Logic and Execute the Fault Handler

To interrupt the execution of logic and execute the fault handler, perform this
procedure.
1. In the Controller Organizer of RSLogix 5000 programming software,
right-click the module and choose Properties.
The Module Properties dialog box appears.
2. Click the Connection and check Major Fault On Controller If
Connection Fails While in Run Mode checkbox.
3. Click OK.
4. Develop a routine for the Controller Fault Handler.
With RSLogix 5000 programming software, you can specify a percentage for the
system overhead time slice. A Logix5000 controller communicates with other
devices (I/O modules, controllers, HMI terminals) at either a specified rate
(scheduled) or when there is processing time available to service the
communication (unscheduled).
Service communication is any communication that you do not configure through
the I/O configuration folder of the project.
•The system overhead time slice specifies the percentage of time (excluding
the time for periodic or event tasks) that the controller devotes to service
communication.
