Terminology Description
signals, such as analog input, analog output, digital input, digital output
and pulse input.
Onboard
IOM
I/O Module (IOM) 'onboard' with the CPM
OPC UA An industrial machine-to-machine (M2M) communication protocol is
developed by the OPC Foundation, which provides a path forward from
the original OPC communications model (namely the Microsoft
Windows only process exchange COM/DCOM) to a cross-platform
service-oriented architecture (SOA) for process control, while enhancing
security and providing an information model.
Originator Originator is the controller that initiate any data exchange with
EtherNet/IP devices on the EtherNet/IP network.
PSM Power Status Module
PSU Power Supply Unit
Redundant
CPM Rack
Rack installed redundant CPM
Right End
Plate
A right end plate is required at the end of each row of expansion I/O
modules, including the row connected to a controller. It allows
additional rows to be added or terminates the I/O network.
RIUP Removal and Insertion Under Power
RPI Requested Packet Interval. The repetitive interval by which assemblies
are periodically transported over EtherNet/IP I/O connections between
Producer and Consumer.
RTU Remote Terminal Unit
SCADA Supervisory Control and Data Acquisition
Scanner A device which connects to the EtherNet/IP network to act as a client of
other EtherNet/IP connected devices. ControlEdge 900 Controller acts
as EtherNet/IP Scanner. It connects to and exchanges data with
Adapters of Modular IO stations, directly connected devices and
Rockwell AB ControLogix controllers.
SIM-300 Simulation for C300
SIM-ACE Simulation for ACE
Target Target is the EtherNet/IP device that address any data requests
