My company purchased a Compact Rio with eight 9237 modules to do strain gauge measurement and I have to program cRio. Unfortunately I am very fresh in LabView and I don't know how to start. I have seen NI-9237-Getting Started-Scan Mode and cRio Embedded Data Logger examples, but first one is too poor. The second one would be perfect but require FPGA and we don't have it. I would be extremely thankful if someone could sent me some appropriate example or instruction how to do it. We have cRio 9022 and LabView 2010.

Hi, Tom!
I am glad to hear that you started to use LV.
Because you mentioned that you are new in LV, I would suggest you to read next few documents, that can be usefull for you.
Using NI CompactRIO Scan Mode with NI LabVIEW Software ( http://zone.ni.com/devzone/cda/tut/p/id/7338).
If you are interested in some advanced functions that you can use for programing in Scan mode, please take a look next documents:
How Do I Programmatically Set Module I/O Properties When Using CompactRIO Scan Mode? (http://digital.ni.com/public.nsf/allkb/37F5B88B83F4FAAE862577080082698E?OpenDocument) or
Programmatic Discovery, Configuration, and Access of CompactRIO Scan Mode I/O with LabVIEW (http://zone.ni.com/devzone/cda/tut/p/id/9351).
Example that you mentioned (NI-9237-Getting Started-Scan Mode) is made to be used at starting point. Idea is to add additional parts in this code to adjust program to your needs.
More advanced program, that you can find in Example finder is RIO IO Scan Embedded Data Logger.lvproj.
I think that you should start from NI 9237-Getting started-Scan Mode.lvproj (from Example finder). After you try it, you can add new features to it and adjust it to you needs.
Please let me know if you have extra questions.
Best regards,

Hello Sofija
Thank you very much for your advices! I think example RIO IO Scan Embedded Data Logger.lvproj could be very useful for me. Is it possible to use it with 9237 modules? I need only calibrate and aquire data from a strain gauges and save it to a file.
Thank you in advance.

Hi, Tom!
I think that the best way to find answer on your last question is to run example and try. If it does not work, probably you should do small changes.
You will get information what is wrong, so those informations will guide you to proper settings.
Enjoy your day!
