FloBoss 407 Instruction Manual
Rev 5/00 G-5
R
Rack — For a ROC or FloBoss, a rack is a row of slots into which I/O modules may be plugged.
The rack is given a letter to physically identify an I/O channel location, such as “A” for the first
rack. Built-in I/O channels are assigned a rack identifier of “A,” while diagnostic I/O channels
are considered to be in rack “E”.
RAM — Random Access Memory. In a ROC or FloBoss, it is used to store history, data, most user
programs, and additional configuration data.
RBX — Report-by-exception. In a ROC or FloBoss, it always refers to spontaneous RBX in which
the ROC/FloBoss contacts the host to report an alarm condition.
RFI — Radio frequency interference.
RI — Ring Indicator modem communications signal.
ROC — Remote Operations Controller, Fisher Control’s microprocessor-based unit that provides
remote monitoring and control.
ROCLINK — Configuration software used to configure ROC or FloBoss units to gather data, as
well as most other functions.
ROCPAC Module — ROM and RAM module that contains the operating system, applications
firmware, and communications protocol in a ROC300-Series unit.
ROM — Read-only memory. Typically used to store firmware. Flash memory.
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 like silicone rubber.
RXD — Received data communications signal.
S
SAMA — Scientific Apparatus Maker’s Association.
Script — A 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. Refer to RBX.
SVA — Signal Value Analog.
SVD — Signal Value Discrete.
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.
