WCC3.EXE SCREEN DESCRIPTIONS
PID Programs Screen
PID Mode:
This tells the PID program to run one of the three supported
formulas.
Current State:
This shows the current PID state which can be <Idle>, <Running>
or <Tuning>.
Maximum Output:
This limits the maximum output value this PID program can
produce.
Minimum Output:
This limits the Minimum output value this PID program can
produce.
Default Output:
This tells the PID program the default output value when this PID
program is not activated.
RESET:
This commands the PID program to reset its state to <Idle>.
TUNING:
This commands the PID program to <Tuning> state.
USE TUNED DATA
This commands the PID program to use the tuned parameters as
the three PID parameters.
Simple PID Mode
Proportional Gain:
This defi nes the Proportional Gain of the simple PID formula.
Integrator Gain:
This defi nes the Integrator Gain of the simple PID formula.
Derivative Gain:
This defi nes the Derivative Gain of the simple PID formula.
Maximum Integrator Value:
This defi nes the absolute maximum the Integrator Value can be.
Maximum Derivative Value:
This defi nes the absolute maximum the Derivative Value can be.
Current Proportional:
This shows the current Proportional portion of the output.
Current Integrator:
This shows the current Integral portion of the output.
Current Derivative:
This shows the current Derivative portion of the output.
Current Error:
This shows the current error between the Setpoint and Sampling
value.
