Hi Santhosh,

Thank you for your recommendation. What about the CRIO? which one should I use?

There are a few options for chassis and controllers, you need to choose one based on your application need. If all that you need is to gather data from SPI/I2C, RS422/485, RS232, you don't need a cRIO at all.

 

cRIO is used for time-critical applications.
