RTU Remote Terminal Unit.
RTV Room Temperature Vulcanizing, typically a sealant or caulk such as silicon rubber.
Serial Communications Protocol using three or more signal lines, intended for short
RS-232
distances. Also referred to as the EIA-232 standard.
RS-422 Serial Communications Protocol using four signal lines. Also referred to as the EIA-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
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.
Slow Pulse Input.
SPI
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.
SVA Signal Value Analog. Stored in the Results Register, it is the analog value that is
passed between functions in an FST.
Signal Value Discrete. Stored in the Compare Flag, it is the discrete value that is
SVD
passed down the sequence of functions in an FST.
System Configured parameters that describe the ROC; set using ROCLINK software.
Variables
T
T/C Thermocouple Input.
TCP/IP Transmission Control Protocol/Internet Protocol.
TDI Time Duration Input.
TDO Time Duration Output.
Tf Flowing temperature.
TLP Type (of point), Logical (or point) number, and Parameter number.
TX or TXD Transmitted Data communications signal.
Turbine meter A device used to measure flow rate and other parameters.
U
Upload Transmit data, a file, or a program from the ROC to a PC or other host.
V-Z
V Volts.
