nVidia has bought Arm Holdings. Many of the more powerful PLCs already use Arm CPUs.
OK, so what?
PLCs execute ladder in sequence but it is a simply trying to imitate relay circuits like the ones I was trained on back in the 1970s are probably didn't change much in the previous 70 years before then.
Things are going to change. As you know nVidia makes graphics cards and specifically GPUs called CUDA cores. These allow computations in parallel and even do AI applications. The CUDA cores could effectively process a relay ladder circuit in parallel so the scan times are insignificant. This will affect motion controllers too. imagine being able to process many axes of motion in parallel. The only draw backs now are software and the heat generated by the GPUs.
You may think that the speed is not necessary but wait. People will find a use for it and the money will go to the ones who find a way.
nVidia is moving our cheese.

I can think of how this will change the motion control industry. Distributed motion control will change. The need for smart remote devices will drop. There will still be a need for the distributed I/O through a network.
BTW, I bought a GTX 1080 with 2560 CUDA cores for playing Stockfish ,a chess program, on my computer. Human players can't beat Stockfish or Lela Chess 0.
