R
(continued)
RAM Random Access Memory. RAM is used to store history, data, most user programs, and
additional configuration data.
RBX Report-by-exception. RBX always refers to Spontaneous RBX in which the ROC
contacts the host to report an alarm condition.
RR Results Register; stores the Signal Value Analog (SVA).
RFI Radio Frequency Interference.
RI Ring Indicator modem communications signal.
Remote Operations Controller microprocessor-based unit that provides remote
ROC
monitoring and control.
ROCLINK 800 Microsoft® Windows®-based software used to configure functionality in ROC units.
ROM Read-only memory. Typically used to store firmware. Flash memory.
Rotary Meter A positive displacement meter used to measure flow rate, also known as a Roots
meter.
RTC Real-Time Clock.
RTD Resistance Temperature Detector.
RTS Ready to Send modem communications signal.
RTU Remote Terminal Unit.
RTV Room Temperature Vulcanizing, typically a sealant or caulk such as silicon rubber.
RS-232 Serial Communications Protocol using three or more signal lines, intended for short
distances. Also referred to as the EIA-232 standard.
Serial Communications Protocol using four signal lines. Also referred to as the EIA-422
RS-422
standard.
RS-485 Serial Communications Protocol requiring only two signal lines. Can allow up to 32
devices to be connected together in a daisy-chained fashion. Also referred to as the
EIA-485 standard.
RX or RXD Received Data communications signal.
S
Scientific Apparatus Maker's Association.
SAMA
Script An uncompiled text file (such as keystrokes for a macro) that a program interprets in
order to perform certain functions. Typically, the end user can easily create or edit
scripts to customize the software.
Soft Points A type of ROC point with generic parameters that can be configured to hold data as
desired by the user.
SP Setpoint, or Static Pressure.
SPI Slow Pulse Input.
SPK Speaker.
SRAM Static Random Access Memory. Stores data as long as power is applied; typically
backed up by a lithium battery or supercapacitor.
Spontaneous Report-By-Exception. SRBX always refers to Spontaneous RBX in which
SRBX
the ROC contacts the host to report an alarm condition.
