Rosemount 3095FC
Glossary-4
On-line - Accomplished while connected (by a communications link) to the target device. For example, on-line
configuration is configuring a Rosemount User Interface Software while connected to it, so that current parameter
values are viewed and new values can be loaded immediately.
OP - Operator Port; see LOI.
Opcode - Type of message protocol used by the 3095FC to communicate with Rosemount User Interface
Software, as well as host PC with Rosemount User Interface Software driver software.
P, Q
Parameter - A property of a point that typically can be configured or set by the user. For example, the Point Tag ID
is a parameter of an Analog Input point. Parameters are normally edited by using configuration software running on
a PC.
Pf - Flowing pressure.
PC - Personal computer.
P/PD - Pressure / DP
PI - Pulse Input. Also referred to as PIN.
Point - Software-oriented term for an I/O channel or some other function, such as a flow calculation. Points are
defined by a collection of parameters.
Point Number - The number of an I/O point as installed in the 3095FC system.
Point Type - The point type attribute defines the database point to have one of the possible types of pints available
to the system. The point type determines the basic functions of a point.
Preset - Number value previously determined for a register.
PRI - Primary PID control loop.
Protocol - A set of standards that enables communication or file transfers between two PCs. Parameters include
baud rate, parity, data bits, stop bit, and the type of duplex.
PSTN - Public Switched Telephone Network.
PT - Process Temperature.
PTI - Periodic Timer Interrupt
PTC - Positive Temperature Coefficient.
PTT - Push-to-Talk signal.
Pulse - Transient variation of a signal whose value is normally constant.
PV - Process variable or process value.
R
RAM - Random Access Memory. In a 3095FC, it is used to store history, data, most user programs, and additional
configuration data.
RBX - Report-by-exception. In a 3095FC, it always refers to spontaneous RBX, in which the 3095FC contacts the
host to report an alarm condition.
RFI - Radio frequency interference.
RI - Ring Indicator modem communications signal.
User Interface Software - Remote Operations Controller is a microprocessor-based unit that provides remote
monitoring and control.
Rosemount User Interface Software - Configuration software used to configure 3095FC units.
