Common Features
The table below lists features common to all ControlLogix digital I/O modules.
Removal and Insertion Under Power
All ControlLogix I/O modules may be inserted and removed from the chassis
while power is applied. This feature allows greater availability of the overall
control system. While the module is being removed or inserted, there is no
additional disruption to the rest of the control process. This helps prevent an
entire production line from having to be shut down.
Module Fault Reporting
ControlLogix digital I/O modules provide both hardware and software
indication when a module fault has occurred. Each module’s fault status indicator
and RSLogix 5000 software will graphically display this fault and include a fault
message describing the nature of the fault.
This feature lets you determine how your module has been affected and what
action should be taken to resume normal operation.
The 1756-OB16IEF module extends this feature by enabling you to define the
duration of time before the module transitions to On or Off after a fault occurs.
