	BECCO2200 DCA
GE Energy Services	Configuration Guide

Data-collection	A software application that acquires data from and sends data to
application	various intelligent electronic devices. Abbreviated as DCA.
Data-translation	A software application that translates data from one form to
application	another (for example digital input to analog input). A data-
	translation application usually has no direct interface to external
	devices. Abbreviated as DTA.
Decimal	A number system having ten symbols, and where values are
	expressed in the base ten number system.
Hexadecimal	A number system having 16 symbols, and where values are
	expressed in the base 16 number system. Commonly used to
	abbreviate binary data. Sometimes referred to as hex.
	Hexadecimal numbers are often preceded by the prefix 0x.
Master	The client or host station or computer, with which the RTU
	equipment communicates. Also referred to as a host or host
	computer.
Non-volatile	A semi-permanent type of data storage (memory)
random-access
memory	that is backed up by batteries to maintain stored data even if
	system power is lost. Can be both read and changed by the
	system. Abbreviated as NVRAM.
Port	An interface point connecting a communications channel and a
	device.
Random-access	A type of temporary data storage (memory) that can be read and
memory	changed while the computer is in use. Data stored in random-
	access memory is lost if the system loses power. Abbreviated as
	RAM.
Read-only	A type of permanent data storage (memory) that can be read but
memory	not altered by the system. Data stored in read-only memory is not
	affected by power loss to the system. Abbreviated as ROM.
Remote terminal	A piece of equipment located at a distance from a master station
unit	to monitor and control the status of outlying equipment, and to
	communicate the information back to the master station or host.
	Abbreviated as RTU.
Sequence of	A time-tagged change of state, logged as part of a chronological
events	record of significant changes in the condition of a particular point
	or points being monitored. Abbreviated as SOE.
Slave	See sub-remote unit.
Source code	A piece of code that has not yet been compiled or assembled (that
	is, it is still in the language it was programmed in) and so cannot
	yet run on a machine.
Sub-remote unit	A physical device (e.g., peripheral boards, D20 RTUs, non-D20
	RTUs, meters, or other intelligent electronic device) that collects
	data, processes it in some way, and communicates it to a master
	remote unit (MRU). SRUs (also called slave units) are able to
	respond to commands from MRUs.
WESDAC	A module of software that manages the transfer, storage, and
