Complimentary Metal Oxide Semiconductor (CMOS)
A family of digital integrated circuits that use transistors operating in a
push-pull mode to carry out logic functions. A CMOS usually is capable
of low-powered operation.
Computer/Highway Interface Package (CHIP)
A PROVOX software product that allows user-written programs to
interact with the PROVOX system. There are different CHIP versions, so
that any of several types of computers can be the host computer.
Computer Integrated Manufacturing (CIM)
A philosophy of industrial design and manufacture that uses
computer-based systems to integrate and coordinate engineering
functions, business functions, and factory operations.
Computer Interface Unit (CIU)
A set of cards that acts as a protocol converter to the CCON, BCON, or
CCOMP, to interface with the PROVOX data highway.
CONFIG Abbreviation: Configuration
Configuration (CONFIG)
Giving instructions and supplying reference information to the controllers
and other devices that make up a process control instrumentation
system. For some PROVOX systems, configuration consists of
responding to prompts in a series of console screen displays. For other
PROVOX systems, configuration consists of creating and manipulating
special ASCII text files.
Controller A device that operates automatically to regulate a controlled variable.
Controller Algorithm
A mathematical representation of a control action to be performed.
Control Algorithm
A mathematical representation of a control action to be performed.
Control Loop An arrangement of mechanical and electronic components for process
control. A product flows through one or more mechanical components of
the loop. The electronic components of the loop continuously measure
one or more aspects of the product flow, then alter those aspects as
necessary to acheive a desired process condition. A simple control loop
measures only one variable. More sophisticated control loops measure
many variables and maintain specified relationships between those
variables.
Control Room Instrumentation (CRI)
1. Process control equipment designed for installation and operation in a
control room environment.
2. A former name for the department at Fisher Controls that designs
PROVOX systems. (The current name for this department is Process
Instrumentation, or PI.)
