Processing Details
Conducts process value
derivative type PID operations.
(Incomplete derivative) Performs
SV setting processing, tracking
processing, gain Kp operation
processing, PID operation and
deviation check.
Performs 2-degree-of-freedom
PID operation (incomplete
derivative).
Performs SV setting processing,
tracking processing, gain Kp
operation processing, 2-degree-
of-freedom PID operation and
deviation check.
Performs position type PID
operation.
Performs SV setting processing,
tracking processing, gain Kp
operation processing, PID
operation, deviation check and
operation mode judgment.
According to the result, performs
change rate, upper/lower limiter
and output on time conversion or
performs alarm clear processing
and output on time conversion.
Judges between the operating
time and hold time, and if it is the
operating time, performs SV
setting processing, tracking
processing, gain Kp operation
processing, SPI operation and
deviation check.
Performs I-PD operation.
Performs SV setting processing,
tracking processing, gain Kp
operation processing, IPD
operation and deviation check.
Performs blend PI operation.
Performs SV setting processing,
tracking processing, gain Kp
operation processing, BPI
operation and deviation check.
Performs engineering value
conversion, tracking processing,
change rate limiter and ratio
operation on the input data.
Conducts an Upper limit
value/lower limit value check of
the PV output by the S.IN
instruction.
Conducts lead-lag compensation
for input data and outputs the
operation results.
