GLOSSARY OF TERMS AND ABBREVIATIONS
Term
Definition
A/D Conversion
Analog-to-digital conversion; process of generating a digital, (numeric) value
representing the magnitude of an analog signal.
Analog Signal
A variable input signal that may be any value within a given range.
Cold Junction
Reference
The ambient temperature at the bimetal junction of terminated thermocouple wires.
Common Mode
Isolation
Indicates the ability to isolate common mode voltages between inputs and outputs
and protect a measurement circuit from damage up to a maximum specified voltage
level. Also indicates the ability to reject the common mode voltage by a specified
amount (in units of dB at a specific frequency, such as 60 Hz).
Configuration
A control strategy with function blocks.
Controlway
A redundant peer-to-peer communication path for point data transfer between
intelligent modules within a process control unit.
Digital Signal
A discrete input signal having only ON and OFF states.
Digital Value
The representation of a value by some number of digital bits that is capable of being
read by a microprocessor.
Dipshunt
Dual in-line package with shorting bars.
Dipswitch
A dual in-line package that contains single pole switches.
Dual Port RAM
(DPRAM)
SRAM shared by two devices. Either device can write or read to the SRAM
simultaneously through separate address and data ports.
EWS
Engineering Work Station; an integrated hardware and software personal computer
system for configuring and monitoring INFI 90 modules and systems.
Function Code (FC) An algorithm that defines specific functions. These functions link together to form the
control strategy.
