5-16 Using the Sequence of Events Module Features
Other Inherent
Module Features Table 5.5 lists features on the Sequence of Events module that cannot
be configured.
Removal and Insertion Under Power (RIUP)
The Sequence of Events module is designed to be installed or
removed while chassis power is applied.
Repeated electrical arcing causes excessive wear to contacts on both
the module and its mating connector. Worn contacts may create
electrical resistance that can affect module operation.
Module Fault Reporting
Your Sequence of Events module provides both a hardware and
software indication when a module fault occurs. The module’s status
indicator and RSLogix 5000 graphically display each fault and include
a fault message describing the nature of the fault.
This feature allows you to determine how the fault affects your
module and what action you should take to resume normal operation.
For more information on how to use hardware and software indicators
when a module fault occurs, see Chapter 8, Troubleshooting the
Sequence of Events Module.

WARNING
When you insert or remove the module while
backplane power is on, an electrical arc can occur.
This could cause an explosion in hazardous
location installations. Be sure that power is
removed or the area is nonhazardous before
proceeding.
