RI
– Ring Indicator modem communications signal.
ROC
– Remote Operations Controller, Emerson Process Management’s microprocessor-based unit that
provides remote monitoring and control.
ROCLINK
and
ROCLINK 800
– Configuration software used to configure ROC units to gather data,
as well as most other functions.
ROM
– Read-only memory. Typically used to store firmware.
RTD
– Resistance Temperature Detector.
RTS
– Ready to Send modem communications signal.
RTV
– Room Temperature Vulcanizing, typically a sealant or caulk like silicone rubber.
RXD
– Received Data communications signal.
S
SAMA
– Scientific Apparatus Maker’s Association.
Script
– An uncompiled text file (such as keystrokes for a macro) that is interpreted by a program to
perform certain functions. Typically, scripts can be easily created or edited by the end-user 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.
SRBX
– Spontaneous-Report-by-Exception. In a ROC, it always refers to SRBX in which the ROC
contacts the host to report an alarm condition.
T-Z
TDI
– Timed Discrete Input, or Timed Duration Input.
TDO
– Timed Discrete Output, or Timed Duration Output.
Tf
– Flowing temperature.
TLP
– Type (of point), Logical (or point) number, and Parameter number.
TXD
– Transmitted Data communications signal.
