Term Description
Controlway High speed, redundant, peer-to-peer communication link. Used to transfer
information between intelligent modules within a process control unit.
CSA Canadian Standards Association.
CTT Configuration tuning terminal. A handheld module used for local configura-
tion, tuning, and monitoring of module values within a process control unit.
DCE Data communication equipment or data circuit-terminating equipment.
Equipment that establishes and terminates a communication link between
two devices. In RS-232-C communication systems, the DCE nomenclature
indicates the signals that appear at specified cable connection contacts. A
modem is an example of this type of device.
Dipswitch A dual in-line package that contains switches.
DTE Data terminal equipment. Equipment comprising the data source, data sink
or both that provides the communication control function. In RS-232-C com-
munication systems, the DTE nomenclature indicates the signals that
appear at specified cable connection contacts. Terminals and printers are
examples of this type of device.
DMA Direct memory access. A method by which data gets transferred directly to
memory without processor intervention.
ESD Electrostatic sensitive devices. Electronic components subject to damage or
failure when exposed to an electrostatic charge; require special handling.
EWS Engineering work station. An integrated hardware and software personal
computer system for configuring and monitoring INFI 90/ Network 90 mod-
ules.
LED Light emitting diode.
MFP Multi-function processor module.
MMU Module mounting unit. A card cage that provides electrical and communica-
tion support for INFI 90/Network 90 modules.
Module Address A unique identifier of a specific device or a communication channel. It refers
to Controlway or module bus address.
Module Bus Peer to peer communication link used to transfer information between intelli-
gent modules within a process control unit.
PCU Process control unit. A node on the plant-wide communication network con-
taining master and slave modules.
PLD Programmable logic device.
ROS Resident operating system.
