I have a vacuum and pressure transducer input to my FP-A1-110 and cFP-A1-110 module. I have scaled the data in Measurement Automation, but the scaled data is not coming through to my vi for logging the data. I have made sure the FieldPoint module in my vi is updated. What am I missing? Do I have to add the same scaling to my vi to get my numbers in PSI and mTorr?
Regards,
Ron

Ron,
Did you make sure the settings were downloaded to the fieldpoint controller after you created the scale?
Exactly how are you reading the cFP I/O? Are you using a FieldPoint Read or a bound shared variable?

I am using the Field Point express vi. Yes, after I enter my scaling information, I apply it and then save it to the iak file.

Ronster,
Try setting up the scales from inside your project instead of MAX. See this http://digital.ni.com/public.nsf/allkb/5A1BEE79660CBBAB8625712D00766FE1.
