Replace FP by NI cDAQ AO/DO/AI/DI modules

[Vills]

I have a few questions regarding the field point modules. We were using field point analog/digital input/output modules earlier and have now decided to change to new NI cDAQ9172analog/digital input/output modules like NI9474 (DO), NI9263 (AO), NI9203 (AI). So we need to replace the existing sub VIs like FP Read/Write (Polymorphic).vi etc. by approriate VIs which will perform the equivalent operation for the new modules.

1) Is field point compatible with Labview 8.6?

2) How can I replace field point VIs like "FP Write (Polymorphic).vi" by VIs for NI analog/digital input/output modules? Do I just need to add a DAQ Assistant from the functions palette?

3) We used to save the last configuration with iak file. Now if we change to the newer modules, how can we save the last configuration of these NI modules for cDAQ9172? 

Thank you,

Vilas

Hey Vilas,

You'll use the DAQmx pallete in the Measurement I/O pallete to find all of the Vis needed to replace your FP Read.vi and FP Write.vi functions.  They'll be polymorphic VIs like DAQmx Read.vi, DAQmx Write.vi, etc....

The DAQ Assistant is an express VI used to easily configure analog or digital inputs or outputs but is not highly recommended due to the software overheard it contains.  It's more efficient programming to do the lower lever programming with the DAQmx functions.

I'm not too familiar with the saving process for FP configurations but I know you can save hardware configurations using Measurement and Automation Explorer.

Let me know if you need more information or if I didn't address your questions correctly.

Thanks,

Hello Aaron,

Thanks a lot for your reply. I don't want to save FP configurations, but I want to save cDAQ9172 - AO/DO/AI/DI configurations. I use these modules to operate mass flow controllers (very similar to valves). I just need to save the inputs I give to all of these Analog/digital input/output modules, so that next time when I open the program, I need not give all the inputs again.

I know that in field point, this is done using IAK file. 

Thank you,

You can save your hardware and tasks/channels configurations in Measurement and Automation Explorer.  This will keep everything in order and allow you to put that same configuration on other machines.  It's always best practice though to go through after you've deployed the configuration file to make sure that the hardware and everything is properly configured.

Thanks,
