Glossary-3
AO Acronym: Analog Output
APU Acronym: Arithmetic Processing Unit
Architecture The arrangement and interconnection of the various parts of a
microprocessor or computer system.
Arithmetic Logic Unit (ALU)
A circuit component that performs complex mathematical calculations. In
effect, an ALU is a very specialized MPU.
Arithmetic Processing Unit (APU)
An electronic device that performs arithmetic calculations using hardware
or logic functions, instead of a long series of computer instructions.
ARW Acronym: Anti-Reset Windup
ASCII 1. A standard digital encoding scheme for data: a 7-bit binary code
represents numbers, letters, symbols, and control codes. (The
designation is an acronym for American Standard Code for Information
Interchange.)
2. A PROVOX point type. An ASCII point contains a single real value,
referenced by the setpoint attribute, and an 80-character ASCII string.
Assembly (ASSY)
In PROVOX, a collection of hardware and/or PWB modules, or a single
PWB module that is built up from individual components.
ASSY Abbreviation: Assembly
Asynchronous Communications Interface Adaptor (ACIA)
1. An integrated circuit that provides data formatting and control for serial
asynchronous data communications. Provides an interface between an
MPU data bus and external devices that have a serial data format.
2. In PROVOX, an integrated circuit (Motorola 86B50) which is used to
interface regulatory controllers to DCUs.
Attribute An individual parameter of a process control point. Also the name of a
PROVOX data type.
AUT Abbreviation: Automatic Mode
AUTO Abbreviation: Automatic Mode
Automatic Mode (AUT or AUTO)
A loop or point control mode: the control algorithm changes the control
output to minimize the difference between the values of the setpoint and
the process variable. An operator supplies the setpoint value.
AUX EU Acronym: Auxiliary Engineering Units
AWG Acronym: American Wire Gauge
AO - AWG
