The OptoENET PID Module Tuner Options window appears:
2.
In the Limits section, enter setpoint, process variable, and output limit values.
3.
In the Configuration section, enter PID loop base time and scan time values.
If needed for your PID control application, also enter values for TPO period, filter
exponential, output slew, and output deadband.
4.
In the Control section, do the following:
a.
To use an internal setpoint value, select the Setpoint Source checkbox. Deselect the
checkbox to use an external analog input for the setpoint.
b.
To use an internal process variable, select the Process Source checkbox. Deselect the
checkbox to use an external analog input for the process variable.
c.
To have PID output use a time-proportional (TPO) signal, select the TPO Output
checkbox. Deselect the checkbox to use a regular analog signal.
If TPO output is used, you should confirm that the TPO Period value in the Configuration
section is correct for your application.
d.
To use the inverse of the PID output value, select the PID Inverse checkbox. Deselect
the checkbox to use a regular noninverted signal.
If Setpoint Source or Process Source is selected (that is, an internal setpoint or process
variable is used), values are displayed in raw counts. If Setpoint Source or Process Source
is not selected (that is, an internal setpoint or process variable is not used), values are from
0 to 10, corresponding to the 0–10 VDC analog input signal.
