Getting PID Configuration Values from Watlow F4

[diarmaede]

All,

I downloaded the Watlow F4 drivers from here:

I see the VI I can use to configure the PID settings, but I have not found an easy way to read the current PID configuration settings.  I could write some code to do that, but it's been quite a few years since I wrote any code to interact with an F4, and I don't want to reinvent the wheel if I don't have to.

Does anyone know of a pre-written VI that queries an F4 and returns the PID configuration values?

Thanks in advance.

Hi diarmaede,

Personally I don't have any experience with the Watlow F4 drivers, but if no one replies with knowledge of any VI's to query the device and return the PID configuration values, feel free to ask any questions you might have in the process of creating your own. I'm sure our community will have insight on any roadblocks you might run into.

Thanks, Mark, but I wrote the code myself.  It was very simple.  I just took the program that wrote PID set values and replaced the write function with a read function.  Then do the setup math in reverse and you have the values read by the system.

I appreciate your offer.
