Equipment
Entity that performs an energy transport function, for example: transformer,
circuit breaker, line. It may be stand-alone or interfaced to an automation system
via an integral device or associated external device.
Expandability
The ability of a system to rapidly and efficiently extend to accommodate new
hardware and/or software.
Extensible Mark-up Language (XML)
High-level language that can be used to construct plain-text file formats
describing application-specific structured data. This enables data files to be
generated and read by a computer, and which are also human legible.
XML is independent of platform, for example, hardware, software, and
application, and provides free-extensibility. XML file readers (browsers) are
available that are non-proprietary.
F
Factory Acceptance Test
Customer-agreed functional tests of the specifically manufactured SAS
installation or its parts, using the parameter set for the planned application. This
test should be carried out in the factory of the system integrator by use of
process-simulating test equipment.
Flexibility
Ability of a system to rapidly and efficiently implement functional changes,
including hardware adaptation.
Freeze
To lock and hold a value at that instant. Typically used with measurands and
counters.
Functional Constraint
Property of a data attribute that indicates the services that may be applied to that
data attribute, for example: read value, write value, substitute value, etc.
Functionally Constrained Data
An ordered collection of data having the same functional constraint, for example:
all MX (measurands).
Functionally Constrained Data Attribute
A data attribute to which a specific functional constraint applies.
Functions
Tasks performed by automation systems and their components.
