Error with Pneumatic

We are continuing to have an error 44007 occurred at periodic tasks.vi>>roboti main.vi 2015. Any help would be great. We double checked our wiring and everything is getting power. The compressor just doesn’t want to cooperate with us. Thanks in advance.

Error -44007 means you’re trying to do a RefNum Get on a name that you haven’t done a RefNum Set for. Double-check that you have everything spelled correctly, and that everything’s type matches up (you aren’t accidentally trying to set a Motor when you opened a 2 Motor Drive, for example).

Checked that. Thanks. We had hope it was a simple issue that had been overlooked. Still a struggle. We’ll keep you posted.

We worked it out.

Could anybody walk us through what do, or how to fix the problem?
