IEC 62591 Wireless Interface Instruction Manual (for ROC800-Series and FloBoss 107)
Appendix A – Glossary
A
A/D Analog to Digital signal conversion.
ABS Acrylonitrile Butadiene Styrene.
Active A mode in which the IEC 62591 module sends messages to the wireless network to
Advertising keep radios active for a longer period of time to facilitate quicker detection of new (or
replaced) wireless devices. Because leaving radios on consumes power, active
advertising is only used on certain conditions.
ADC Analog to Digital Converter. Used to convert analog inputs (AI) to a format the flow
computer can use.
AGA American Gas Association. A professional organization that oversees the AGA3
(orifice), AGA5 (heating value), AGA7 (turbine), AGA8 (compressibility), AGA9
(Ultrasonic), and AGA11 (Coriolis) gas flow calculation standards. See
http://www.aga.org.
AWG American Wire Gauge.
AI Analog Input.
AO Analog Output.
Analog Analog data is represented by a continuous variable, such as an electrical current
signal.
AP Absolute Pressure.
API American Petroleum Institute. See http://www.api.org.
Area A user-defined grouping of database entities.
ASCII American (National) Standard Code for Information Interchange.
Attribute A parameter that provides information about an aspect of a database point. For
example, the alarm attribute is an attribute that uniquely identifies the configured value
of an alarm.
B
BMV Base Multiplier Value, used in AGA7 (turbine) calculations.
BPS Bits Per Second, associated with baud rate.
BTU British Thermal Unit, a measure of heat energy.
Built-in I/O I/O channels that are fabricated into the ROC and do not require a separate option.
Also called "on-board" I/O.
Bursting The periodic or trigger-based publishing of cyclical process data without any master or
host action.

Note: This is a generalized glossary of terms. Not all the terms may
necessarily correspond to the particular device or software
described in this manual. For that reason, the term "ROC" is
used to identify all varieties of Remote Operations Controllers
(including ROC800-Series, ROC300-Series, FloBoss
Series, FloBoss 300-Series, FloBoss 500-Series, and FloBoss
407 units).
