Related Terms

This manual uses the following terms:

This term: Means:

Broadcast Data transmissions to all addresses

Communications

format

Format that defines the type of information transferred between an

I/O module and its owner controller. This format also defines the

tags created for each I/O module

Compatible match An electronic keying protection mode that requires the physical

module and the module configured in the software to match

according to vendor, catalog number and major revision. In this

case, the minor revision of the module must be greater than or

equal to that of the configured slot

Connection The communication mechanism from the controller to another

module in the control system

ControlBus The backplane used by the 1756 chassis

Coordinated

System Time

(CST)

Timer value which is kept synchronized for all modules within a

single ControlBus chassis. The CST is a 64 bit number with µs

resolution

Direct connection An I/O connection where the controller establishes an individual

connection with I/O modules

Disable keying Option that turns off all electronic keying to the module. Requires

no attributes of the physical module and the module configured in

the software to match

Download The process of transferring the contents of a project on the

workstation into the controller

Electronic keying A system feature which makes sure that the physical module

attributes are consistent with what was configured in the software

Exact match An electronic keying protection mode that requires the physical

module and the module configured in the software to match

identically, according to vendor, catalog number, major revision and

minor revision

Field side Interface between user field wiring and I/O module

Inhibit A ControlLogix process that allows you to configure an I/O module

but prevent it from communicating with the owner controller. In

this case, the controller does not establish a connection

Listen-only

connection

An I/O connection that allows a controller to monitor I/O module

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

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)

Multicast Data transmissions which reach a specific group of one or more

destinations

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 2ms to 100ms using RSNetWorx
