Glossary
Minor A module that is updated any time there is a change to the module that does not
affect its function or software user interface.
Multicast Data transmissions that reach a specific group of one or more destinations.
Multiple owners A configuration set-up where multiple owner controllers use exactly the same
configuration information to simultaneously own an input module.
Network update time (NUT) The smallest repetitive time interval in which the data can be sent on a
ControlNet network. The NUT may be configured over the range from 2 ms to
100 ms using RSNetWorx software.
Owner controller The controller that creates and stores the primary configuration and
communication connection to a module.
Program mode In this mode, the controller program is not executing. Inputs are actively
producing data. Outputs are not actively controlled and go to their configured
Program mode state.
Remote connection An I/O connection where the controller establishes an individual connection
with I/O modules in a remote chassis.
Removable terminal block (RTB) Field wiring connector for I/O modules.
Removal and insertion under power
(RIUP)
ControlLogix feature that allows a user to install or remove a module or RTB
while power is applied.
Requested packet interval (RPI) A configurable parameter that defines when the module will multicast data.
Run mode In this mode, the controller program is executing. Inputs are actively producing
data, and outputs are actively controlled.
Service A system feature that is performed on user demand.
System side Backplane side of the interface to the I/O module.
Tag A named area of the controller’s memory where data is stored like a variable.
Timestamping ControlLogix process that stamps a change in input, output, or diagnostic data
with a time reference indicating when that change occurred.
