Half of PCM Not Working?

[G_rupp]

No, they are indicators that the switch is working. There is a Simple Solenoid.lvproj xxample in the NI Example Finder. You can see this by selecting Help then Find Examples. This allows you to check the solenoids one at a time. The test has to be stopped and started for each solenoid. While it is running, you can toggle the switch and verify the operation.

The behavior changed when you changed your program. Show us your Periodic Tasks and we'll probably be able to tell you quickly what's wrong with it, and how to fix it.

Also show us Begin so we can verify that the solenoids are being opened as they should be.
