3 Definitions
For the purposes of this document, the following terms and definitions apply. The lEEE Standards DictionaryOnline [B10] should be consulted for terms not defined in this clause.l6, 17
The definitions used in this standard have been derived from the sources cited in Clause 2, “Normative references”with the exception of those introduced in this standard revision, labeled “New]”.
ACTUAL (ACT): The programmed functional capabilities of an End Device.(ANSI CI2.19-1997]
Address: Those inputs whose states select a particular cell or group of cells. (IEEE Standards Dictionaryl
Advanced Metering Infrastructure (AMl): Defined as the communications hardware and software and associatedsystem and data management software that creates a network between advanced meters and utility business systemsand which allows collection and distribution of information to customers and other parties such as competitive retaiproviders, in addition to providing it to the utility itself FERC-727-728-2008
Alias: An alternative name of a Table, Procedure, Element, or a derived type. An alias name can be used as analternative when making references to Tables, Procedures, Elements, or derived types. Example: Table 0 ofANSI C12.19-1997 contains the Element MANUFACTURER, whereas this standard renamed it toDEVICE CLASS, and defined it to be an alias to MANUFACTURER for backward compatibility. All referencesto MANUFACTURER and DEVICE CLASS refer to the same Element.
ARRAY: In text form, “Array” or “array,” a grouping of repetitions of the same data type, used to describe a singleElement.[New]
BIT FIELD (BFLD): In text form, “Bit Field”or “bit field”is a collection of data subelements, each spanning oneor more of bits, that may not be aligned on an Octet boundary nor span an integral multiple of Octets. Multipleoccurrences of these subelements are grouped (packed) together so that the entire collection of bits ends on an Octetboundary. For purposes of transmission, the entire group of bits is treated as an Atomic Element having the type ofunsigned integer.[New]
Block: A collection ofinterval-based Register values spanning one or more channels. New
Channel: A single path for the collection of interval-based Register values over a period of time. New)
Clock: A device that generates periodic signals used for synchronization. A device that measures and indicates timeA register whose content changes at regular intervals in such a way as to measure time. ANSI CI2.19-1997
Count: The number of Octets selected when using the Offset/Octet-count patial Table access method[ANSIC12.19-1997]
Cumulative Demand: Summation of Maximum Demands during the preceding periods is indicated during theperiod after the meter has had a demand reset performed and before it has been reset again. Note that the maximumdemand for any one demand interval is equal or proportional to the difference between the accumulated readingsbefore and after reset.(IEEE Standards Dictionary]
Customer: The purchaser/user of a product or service supplied by a service provider or utility.(AS 4140-1995
