electrical connections for pneumatic

[ultradan]

The team did all the connections for the pneumatic subsystem. However, on the 24v solenoid bumper, the programmer cannot activate the status led (of channels). Our solenoid module is at slot 3 ...and we have the old 8 slot base. the power led is on on the module. Any idea. The programmer did the example on labview.
thanks

Hey ultradan, if you guys have the older 8-slot cRIO, try putting the solenoid module in slot 7 (slot 3 is only used in the new 4-slot cRIO I believe). If you open up the cRIO Imaging Tool on the Classmate laptop, it should indicate which slots have modules in them, and if the modules are in the right slots.

Slot 3 or Slot 7 will work.

The module ordering is as follows:
1: This MUST be an analog module on both cRio's.
2: This MUST be a digital module on both cRio's.
3: Optional solenoid module on both cRio's
4. Optional wildcard module on 4-slot, empty on 8-slot
5: Optional analog on 8-slot
6: Optional digital on 8-slot
7: Optional solenoid on 8-slot
8: Always empty

In LabVIEW, you can address the module as "solenoid module 1" for slot 3 or "solenoid module 2" for slot 7. I don't know what the example uses, check that.

Also, you must have a driver station connected and be enabled for the outputs to turn on. This is probably the cause, if it's not code addressing.

Are you running the solenoid example from the Front Panel?
Pushing the solenoid activating button?

That should turn on the first solenoid light on the solenoid module in slot 3.

OK today, the team tested the compressor & pressure switch logic. Everything seems to work fine...except for the solenoids. We removed the bumper to see if we could only activate the front LED of the module. still under investigation with the programming mentor. Might be something he is missing or not fully understood.We tried to move from slot 3 to slot 7 without success. Then we tried to activate from the NI example, and directly from a small program...without success

Just out of curiosity, are you supplying 24V to the solenoid breakout? You would have to power the solenoid breakout with 24V for your 24V solenoids to work. In order to do this, the breakout would need to be powered from the PD board via the 24V port (same one as the cRIO, just using the other two terminals) vs. plugging it into a 12V output. This is shown in this wiring diagram.

Thanks, this is exactly what we did. The new SMC valves are activated at 24VDC
