Use I/O Modules with CompactLogix 5370 L2 Controllers
Chapter 8
If any issues arise with a removable connector and you suspect a connection point
can no longer be functioning as a complete circuit, you can use a continuity tester
to determine if the connection point is operating correctly, that is, the connection
point is a complete circuit.
The indication mechanism, for example, a light that illuminates on the tester,
varies by continuity tester. The following example graphic shows a continuity
tester with one connection point. In this case, if the circuit is operating correctly,
the indicator light turns on.
Insert a continuity tester into the suspected I/O connection point as shown in
the following graphic.
Remove and Replace the Connector
Complete these steps to remove and replace an embedded I/O module
connector.
1.

2.
Compress the small release clips at the top and bottom of the connecter
and tilt the top of the connector away from the module.
3.
Pull the connector away from the module and disconnect any wires.
4.
Connect the wires to the replacement connector.
