Processing Details
Conducts integral operations on
the input data and outputs the
operation results.
Conducts Derivative operations
on the input data and outputs the
operation results.
Delays the input data by the
specified dead time and then
outputs it.
Outputs the maximum value
among the input data.
Outputs the minimum value
among the input data.
Outputs the middle value between
the maximum value and minimum
value among the input data.
Calculates and outputs the
average value of the input data.
Limits the output value with
hysteresis.
Limits the varying speed of the
output value.
Limits the varying speed of the
output value.
Performs two-position ON/OFF
control.
Performs SV setting processing,
tracking processing, MV
compensation, MV output and
two-position ON/OFF control.
Performs three-position ON/OFF
control.
Performs SV setting processing,
tracking processing, MV
compensation, MV output and
three-position ON/OFF control.
Provides a dead band and
performs output processing.
Provides a control output
according to the SV and MV
pattern.
Outputs the value selected by the
selection signal out of the input
data in the automatic mode, or
outputs the MV of the loop tag
memory in the manual mode.
Brings the output value closer to
the output set value from the
output control value gradually
when the mode select signal is
switched from manual to
automatic.
Increases or decreases the output
value at the fixed rate.
