If you want to go fast. Use ethercat : With XFC it is possible to achieve I/O response times < 100 μs

K1: I need to run ethercat to 0,250 ms Then 100 nanosecond's is within your time responce limit my avatar brother.
If the program style is in interrupt model. You could get some nice output.
Do you application need a cnc application? If you can do the application with logic, use the Etherlab provided c example's.
They work fine and you have direct system control. You can even make a c coded interface gui with QT.
Did you know the russian submarines use a long wave radio frequency for communication into the deep ocean...It's a encrypted signal. The same signal is also used for nuclear warfare. Scary isn't it?
The Enigma was also something like this. It didn't take a long time.

Deep sea code explained pdf :

but no word of deep sea radio frequency... haha. I ask a radio specialist about this option. Maybe we can do this with deep sea freqency with ethercat at nano second's instead of common used "old" main frames.. Why not trigger some whale song's with the Ethercat bus? A tiny solared powered submarine in the middle of the atlantic ocian. Invisible for Us and Russia.
What would happen if it has the Chinese flag on it? I think Trump would say.... Fuck it's a huaway modem.
) ... and value not change and not have errors ... so I TRY TO make a test on 0,15 ms .... and i have an error after some minutes ... so the previousone is valid.!!!
