Configuration of C series card on Ni9038 chassis

[sumit04]

Hi, 

I am using Ni9038 RT chassis for my application. In my application some cards are not performing time critical operation (relay switching, CAN communication), can i configure those cards at host side LabVIEW vis? Configure those card in same fashion we configure cDAQ chassis card. Using cDAQ functions in LabVIEW.

Thanks

Hi sumit04,

There are two ways you could go with this:

1. Switch to a CompactRIO with DAQmx device such as the cRIO-904x or cRIO-905x families of devices. These are our latest CompactRIOs and have support for using modules with DAQmx, RIO Scan Interface, ... Your current cRIO is a bit older and lacks the DAQmx support. 
2. If the specific modules you are using support Scan Interface operations, you can use them in that mode. This would be through I/O Variables rather than a specific API. 

One other comment: For CAN communication if you're using the older NI-CAN modules, those are only supported with FPGA mode. We have a new driver for CAN communication, NI-XNET, for which the modules are all accessible from LabVIEW Real-Time instead of FPGA. 

Overall, I'd recommend taking a look at what you're using in the Software Support for CompactRIO, CompactDAQ, Single-Board RIO, R Series, and EtherCAT page and speaking to NI Support to get a better idea about what options exist and where to look for help implementing them.
