Need PID vi that outputs analog instead of digital (on/off)

[Perryg114]

I am trying to actively control an electron gun filament using a PID vi that I found in some of the examples but it is not proportional control like I need. Instead it is digital on/off. I want to proportionally control the filament voltage. Turning it on and off is not good. I think the vi that I have is simple PID or something like that. It would work fine if it would output an analog value instead of on/off.

Hello Perry,

Wanted to double check whether you are using PID.vi from the PID toolset of LabVIEW. The PID.vi outputs an analog value within the output range that you specify. There are also PID example in the NI example finder that you could take a look at.

Hope this helps.
