Processing details
Reference
S.2PID
Performs two-degree-of-freedom PID control operation (inexact differential).
The instruction performs the following processing steps: SV setting, tracking, gain (Kp) operation,
two-degree-of-freedom PID control operation, and deviation check.
Instruction symbol
Processing details
Reference
S.PIDP
Performs position type PID operation.
The instruction performs the following processing steps: SV setting, tracking, gain (Kp) operation,
PID operation, deviation check, and control mode determination.
Depending on the operation result up to the mode determination processing, the instruction
performs either variation rate & upper/lower limiter and output conversion, or alarm clear and
output conversion processing.
Instruction symbol
Processing details
Reference
S.SPI
Monitors the operating time (operating time (ST) or hold time (HT)), and performs the following
processing steps: SV setting, tracking, gain (Kp) operation, SPI operation, and deviation check if
the operating time is in ST.
Instruction symbol
Processing details
Reference
S.IPD
Performs I-PD operation.

IPD operation, and deviation check.
Instruction symbol
Processing details
Reference
S.BPI
Performs blend PI operation.
The instruction performs the following processing steps: SV setting, tracking, gain Kp operation,
BPI operation, and deviation check.
Instruction symbol
Processing details
Reference
S.R

tracking, variation rate limiter, and ratio calculation.
Instruction symbol
Processing details
Reference
S.PHPL
Checks the range of the PV that has been output by the S.IN instruction.
Instruction symbol
Processing details
Reference
S.LLAG
Performs lead-lag compensation to the input data, and outputs the operation result.
Instruction symbol
Processing details
Reference
S.I
