Glossary
Disable keying
An electronic keying protection mode that 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

Electronic keying
A feature where modules can be requested to perform an electronic check to
make sure that the physical module is consistent with what was configured by
the software
Exact 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, 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 the Hydraulic Servo
module but prevent it from communicating with the owner-controller. In this
case, the controller behaves as if the module does not exist at all
Interface module (IFM)
A module that uses prewired cable to connect wiring to an I/O module
Linear displacement transducer (LDT)
Feedback device connected to the ControlLogix Hydraulic Servo module that
provides axis position data. Any LDT used with the ControlLogix Hydraulic
Servo module should use an external interrogation signal.
