[DCRich]

Mark,

Thanks for the prompt reply. Unfortunately, it does not answer the question that I asked. I understand that if I use only 3 modules, an Analog, a Digital and A Solenoid, then each will be identified as module 1 of that type. If I add a second Digital then it will Module2. But, in an 8 slot cRIO the WPI library needs to know where to find DIO Module 2, will it be in slot 2, 4, 6 or 8?

Then if I write code for the 8 slot cRIO and DIO Module 2 is in slot 6, how do I tell the software that DIO Module 2 is in slot 4 in the cRIO II?
