2.7 Process Control Instructions
Processing details
Performs differential operation to the input data, and outputs the operation result.
Processing details
Delays the output of the input data by the specified dead time.
Processing details
Outputs the maximum value of the input data.
Processing details
Outputs the minimum value of the input data.
Processing details
Outputs the intermediate value (the value between the maximum and minimum values) of the input
data.
Processing details
Calculates the mean (average) value of the input data, and outputs the operation result.
Processing details
Applies a limiter with hysteresis to the output value.
Processing details
Limits the variation speed when the variation rate of the input (E1) exceeds the limit.
Processing details
Holds the last value when the variation rate of the input (E1) exceeds the limit.
Processing details
Performs two-position (on/off) control.
The instruction performs the following processing steps: SV setting, tracking, MV correction, MV
output, and two-position (on/off) control.
Processing details
Performs three-position (on/off) control.
The instruction performs the following processing steps: SV setting, tracking, MV correction, MV
output, and three-position (on/off) control.
Processing details
Provides a dead band and performs output processing.
Processing details
Provides control output according to the SV and MV patterns.
