Interrupt the Execution of Logic and Execute the Fault Handler
Depending on your application, you can want an I/O connection error to cause
the Controller Fault Handler to execute. To do so, set the module property that
causes a major fault to result from an I/O connection error. The major fault
causes the execution of the Controller Fault Handler.
First, develop a routine in the Controller Fault Handler that can respond to I/O
connection faults. In the Module Properties dialog box of the I/O module or
parent communication module, check Major Fault On Controller If Connection
Fails While in Run Mode.
