SCXI-1200 set up

[bfeddeck]

I have a SCXI-1000DC chassis with an SCXI-1200 in slot 1 & SCXI-1102 in slot 2. I set up virtual channels MAP which refers to SCXI-1200 & EGT1 which refers to SCXI-1102. When I run "Cont Acq&Chart (immediate).vi" in LV5.1 calling both channels, I get error -10007. If I call only MAP the vi runs correctly. If I call only EGT1, the vi runs correctly.

Do I have "Devices and Interfaces" set up correctly in MAX?

Greetings,

This appears to be an issue with the channel list you are specifying. The KnowledgeBase linked below details the rules that must be followed when using the SCXI-1200:

Example Channel List for Scanning Multiple Channels on SCXI-1200 in Differential Mode

I hope this helps. Good luck with your application.

Thanks to the excellent support at National Instruments I was able to solve this problem.
It turns out that the problem is the 1200 cannot scan both modules at the same time. I changed the program to call the first module then clear the AI and call the second module.
