MV Manipulated Variable
PV Process Variable
RSP Remote Set Point. This is the set point which is set by the analog input from an external device.
SP Set Point
U Unit. This indicates the minimum digit of the selected PV input range with industrial unit (°C, Pa, L/min., etc.).
1 U = 1 °C in a range of –200 to +200 °C. 1 U = 0.1 °C in a range of 0.0 to 200.0 °C. Additionally, 1 U = 0.01
when the DC voltage input is scaled to 0.00 to 10.00. Furthermore, 0.1 U means 1/10 of 1 U.
