Chapter 6 Place, Configure, and Monitor I/O
End-cap Detection and Module Faults
If a module not adjacent to an end cap experiences a fault and the connection to
the controller is not broken, only the module enters the fault state. If a module
adjacent to an end cap experiences a fault, both the module and the controller
transition to the fault state.
Reconfigure an I/O Module
If an I/O module supports reconfiguration, you can reconfigure the module via:
• the Module Properties dialog box in RSLogix 5000 programming
software.
• a MSG instruction in program logic.
Reconfigure a Module via RSLogix 5000 Programming Software

perform this procedure.
1. Highlight the module in the I/O Configuration tree and right-click to
choose Properties.
