PLC is better than PXI?

[KRAZE4LV]

I have a question in my mind.

What are the limitation of PXI over PLC and What are the advantages of PXI over PLC?

Please leave your comments.

Hi KRAZE4LV,

Comparing PLCs to PXIs can somewhat seem like comparing apples to oranges. While they both have specific uses, along with advantages and disadvantages, I would first steer those interested in this to a brief overview of PXI Systems. We have had customers make the move from PLCs to PXIs. I might consider a cRIO in many cases to be a more direct replacement for PLCs, and there has been a few discussions on this issue. The main constraint of a PLC system is that PLCs are not generally used in harsher environments, and is significantly less rugged than our other systems. Feel free to add your own input though.

Definitely look into cRIO as a direct replacement to a PLC.  We use PXI and cRIO systems (both with RT and both can utilize FPGA's in various ways which I imagine may be something you are looking for if you are choosing a PLC i.e. Reliability and determinism) and mostly it depends on where the system is going and the size / channel count limitations.

Best,
