Abbreviations

Throughout this document the following abbreviations are used:
ADC Analog to Digital converter
AI Analog Input
AO Analog Output
API Application Programming Interface
An interface that allows an application to interact with another application or operating system, in our case, Spirit
Flow-X API is implemented through Excel worksheet functions.
ASCII American Standard Code for Information Interchange.
A set of standard numerical values for printable, control, and special characters used by PCs and most other computers. Other commonly used
codes for character sets are ANSI (used by Windows 3.1+), Unicode (used by Windows 95 and Windows NT), and EBCDIC (Extended Binary-Coded
Decimal Interchange Code, used by IBM for mainframe computers).
CPU Central Processing Unit
DAC Digital to Analog Converter
DCS Distributed Control System
DDE Dynamic Data Exchange
A relatively old mechanism for exchanging simple data among processes in MS-Windows.
DI Digital Input
DO Digital Output
EGU Engineering Units
EIA Electrical Industries Association
FET Field Effect Transistor
GC Gas Chromatograph
GUI Graphical User Interface
HART Highway Addressable Remote Transducer.
A protocol defined by the HART Communication Foundation to exchange information between process control devices such as transmitters and
computers using a two-wire 4-20mA signal on which a digital signal is superimposed using Frequency Shift Keying at 1200 bps.
HMI Human Machine Interface.
Also referred to as a GUI or MMI. This is a process that displays graphics and allows people to interface with the control system in graphic form.
It may contain trends, alarm summaries, pictures, and animations.
I/O Input/Output

P&ID Piping and Instrumentation Diagram
PC Personal Computer
PCB Printed Circuit Board
PLC Programmable Logic Controller.
A specialized device used to provide high-speed, low-level control of a process. It is programmed using Ladder Logic, or some form of structured
language, so that engineers can program it. PLC hardware may have good redundancy and fail-over capabilities.
RS232 EIA standard for point to point serial communications in computer equipment
RS422 EIA standard for two- and four-wire differential unidirectional multi-drop serial
RS485 EIA standard for two-wire differential bidirectional multi-drop serial communications in computer equipment
RTU Remote Terminal Unit
SCADA Supervisory Control and Data Acquisition
SQL Standard Query Language
SVC Supervisory Computer
TCP/IP Transmission Control Protocol/Internet Protocol.
Transmission Control Protocol/Internet Protocol. The control mechanism used by programs that want to speak over the Internet. It was
established in 1968 to help remote tasks communicate over the original ARPANET.
TTL Transistor-Transistor Logic
UART Universal Asynchronous Receiver & Transmitter
URL Uniform Resource Locator.
The global address for documents and resources on the World Wide Web.
XML Extensible Markup Language. A specification for Web
documents that allows developers to create custom tags that enable the definition, transmission, validation and interpretation of data
contained therein.
