Develop Control Applications Chapter 8
You can configure the application so that a response to a failed I/O module
connection can wait until the next program scan. In this case, put the logic in a
normal routine and use the GSV technique that is described on
page 201 to
call the logic.
First, develop a routine in the Controller Fault Handler that can respond to
I/O connection faults. Then, 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.
For more information about programming the Controller Fault Handler, see
the Logix 5000 Major, Minor, and I/O Faults Programming Manual,
publication
1756-PM014.
Sample Controller Projects
Logix Designer application includes sample projects that you can copy and
modify to fit your application. To access the sample projects, click Sample
Project in the Studio 5000® environment interface as shown and navigate to
Samples > ENU > v32 > Rockwell Automation.

TIP
It takes at least 100 milliseconds to detect an I/O connection loss, even if the
Controller Fault Handler is used.
