Initialize Module on Non-Default Slot
 

We have an extra Solenoid breakout we are trying to add. One is wired up for 24V and the other for 12V, and are having trouble initializing the second one. The first one is working perfectly fine. We encountered the same problem with the Analog breakout.

We initialize it like so, in Java:

Upon running the code, it immediately warns us that "Solenoid module 6 is not present" (or something to that effect). Subsequently, it throws an AllocationException.

Any help on initializing a module on its non-default slot?

Because of the new Module naming system, instead of slot number you need to call module number. so instead of 6 you would use 2.

Thanks for the quick reply!

I had a suspicion about that when I was looking at the Javadocs.

But, how does the channel numbering work then? In other words, how would it know which module to go to if there are 2 solenoid breakouts?

If using a 4 slot CRio, slot 1 is analog 1, slot 2 is digital 1, slot 3 is solenoid module 1. slot 4 is the second instance of whatever module you put in it. If using the 8 slot CRIO, 1,2 and 3 are the same as the 4 slot, and the slot 5 is analog 2, slot 6 is digital 2 and slot 7 is solenoid 2.

That makes a lot more sense!

Thanks!

Yeah Thanks a lot I was having this problem and I was ripping my hair out over this and this got it working for me.

We are having the same trouble with the solenoid module. We are using an 8 port CRio, so we have declared our solenoid as
Solenoid s1 = new Solenoid(1,1);
Solenoid s2 = new Solenoid(1,2);

We have the solenoid module plugged into port 8 of the Crio and wired for 24V. We get a power light on the solenoid breakout, but when we upload the Java code, we get the error Solenoid Module 1 is not present (4 times on one deploy). Should any of the 8 leds be on when we boot up to signal that the module has power?

Thanks for the help.

On an 8-slot, Solenoid Modules go in cRIO chassis slots 3 & 7
