Glossary 3
Interface module (IFM)
A module that uses prewired cable to connect wiring to an I/O
module
Major revision
A module revision that is updated any time there is a functional
change to the module
Minor revision
A module revision that is updated any time there is a change to the
module that does not affect its function or interface
Owner-controller
The controller that creates and stores the primary configuration and
communication connection to a module
Program mode
In this mode the following events occur:
• Controller program is not executing.
• Inputs are still actively producing data.
Pulse per second
Process by which the 1756HP-GPS receives the UCT time reference
from the navigation sattelites that are part of the GPS system.
Relative time
Time format used when sorting timestamps in CST format. In this
case, you cannot easily determine what the 64-bit timestamps
represent, but you can determine an order for the timestamps that will
provide a relative reference for when a timestamped transition
occurred.
Remote connection
A connection where the controller establishes an individual
connection with Sequence of Events modules in a remote chassis
Removal and insertion under power (RIUP)
ControlLogix feature that allows a user to install or remove a module
or RTB while power is applied
