Troubleshooting
Chapter 4 provides information to help you troubleshoot your remote
I/O system using the LED indicators on the front of the device
(Figure 4.1). The remote I/O module is a non-serviceable device that
should be returned to Allen-Bradley for replacement when a major
fault exists that is attributable to the remote I/O communications
module itself.
