A ControlLogix process that allows you to configure a SynchLink

module but prevent it from communicating with the owner controller.

Hub

Distribution unit in the star configuration that consists of a single base

block and up to 4 splitter blocks. Unidirectional data passes through

the hub.

Listen-only connection

data without owning the module.

Major revision

A module revision that is updated any time there is a functional

change to the module resulting in an interface change with software.

Master node

A node in any SynchLink configuration that serves as the Time Master.

Minor revision

A module revision that is updated any time there is a change to the

module that does not affect its function or software user interface

(e.g. bug fix).

Owner controller

The controller that creates and stores the primary configuration and

communication connection to a module.
