When the PID loop is correctly optimized, click Disconnect to close the link to the Ethernet
brain, and then select File
➞
Exit to close OptoENET PID Module Tuner.
IMPORTANT:
Do not click Manual Mode before disconnecting the Ethernet link and closing
OptoENET PID Module Tuner. This will stop the PID calculations that are running on the
SNAP-PID-V module, and your PID loop will no longer be controlled by the PID module.
Saving PID Values to a Log File
You can use OptoENET PID Module Tuner to create a log file that contains process variable,
setpoint, output, and other PID values. To create the log file, do the following:
1.
Select the Log File checkbox in the OptoENET PID Module Tuner main window.
2.
In the file dialog box that appears, enter a name for the file, choose the location where you
want to save it, and then click Save.
Whenever PID values are graphed in the main window, OptoENET PID Module Tuner will
record the data listed below in an ASCII text file that you can open using a spreadsheet,
word processor, or other software application.
– PID calculation date and time
– Setpoint
– Gain
– Integral
– Derivative
– Current process variable
– Last process variable
– Oldest process variable
– Current error
– Last error
– Output change
– Output value
– Time remaining to next scan/PID calculation
Using the SNAP PID Module with OptoControl
The SNAP-PID-V module can be used as an analog input module with Opto 22’s OptoControl
industrial automation software. OptoControl R3.1d or newer is required to use the SNAP-PID-V
with OptoControl. Contact Opto 22 Product Support for additional information. Contact

Using Analog Inputs
In OptoControl you can configure two types of analog input points with the SNAP-PID-V. Both
types of input points can range from 0 to 100 percent; one type is scalable and the other is not.
