Moving from cRIO to myRIO

[NaveenRonnie]

Hey!

Currently I've got a system setup using NI cRio-9012, NI 9477, NI9263 and NI 9205.

This system has the following connect to the inputs/outputs:

1. Inputs: Receives 2 analog pressure sensor values

2. Outputs: 7 digital outputs connected to a driver circuit running hydraulic/pneumatic valves  

3. Outputs: 2 analog signals to a driver circuit running variable hydraulic/pneumatic valves  

The LabView program has 3 independent control loops that do the following:

Loop 1 and 2: receive input from the respective pressure sensor and control the variable valves (depending on input from user (front panel)).

Loop 3: Switch on and off the remaining 7 valves depending on input from user (front panel)

At the moment the cRIO system that I am using handles the whole system perfectly, but I am keen on a more portable system and intend to use the cRIO for a different application.

So my query is would myRIO be able to substitute the cRIO for my application? I do also intend to add additional sensors/outputs and communication too.

Thank you for going through my query!

The only potential issue I see with moving the project to the myRIO is the specs you might need on your I/O. For example, the 9477 is capable of 5 to 60V output where as the myRIO is only capably of 3.3V LVTTL output. Ultimately, it comes down to yours specific I/O needs - I've linked the manual and specifications for the myRIO-1900 below. I'd recommend looking it over to make sure that it will meet your application requirements.

On the software side, there shouldn't be too many adjustments that need to be made - the myRIO has the same processing architecture as the cRIO.

Thanks! Will check it out!
