Labview compressor problems

When building our software, I couldn’t find an input for where the compressor goes, like when you have a motor, it has an input for a PWM slot, but I didn’t find anything on the compressor. does anyone have any ideas what is wrong? All responses are accepted… written, diagram, or otherwise.

The compressor code is in the Timed Tasks VI it has a disable structure around it. It is designed to be connected to a spike relay witch connects to a PWM port

I’m confused what you mean… Could you explain it more clearly?

Here’s an example:

The compressor connects to a Spike.
The Spike is controlled from Relay 1 (in this example) on the Digital sidecar.
Digital Input 1 is where the pressure sensor connects on the Digital sidecar.
