OMRON

4. Abbreviations and names

SV: Set Value is the set and desired temperature
PV: Process Value is the current, measured temperature
MV: Manipulated Variable is the "power" the controller transmits to
reach the desired temperature
Set point: Also called set value or SV
Sensor: External temperature measuring device
Pt100: The Pt100 is a frequently used temperature reader. The reader
has a resistance value of 100 Ohms at 0 degrees; Pt100s can
be tested for continuity, and must have a value of around 106
Ohms at room temperature. For the Pt100 normal extension
cables can be used
4-20mA: 4-20mA is a signal that is transmitted from certain sensors
(for instance hygrometers), or which is used specifically to
control a device, such as a steam valve
Alarm: An output that is switched on at a certain temperature is often
referred to as an alarm. An alarm output may also be used for
other purposes, depending on its settings.
Heat: This control is used for heating
Cool:
This control is used for cooling
Heat/cool: This control is used for heating as well as cooling; therefore,
two control outputs are used.
PID: Correct PID parameters ensure accurate and stable control.
PID parameters are values that can be changed manually, but
are mostly achieved by running Autotune. PID is the
abbreviation of Proportional, Integration and Differentiation.
