Greetings everybody;
That new card works but in all my hacking on the hal file, I seem to have
lost the feedback path to getting a true signal out of the near module
so the code will actually run once the spindle has been started.
So, I've looked thru the wiki without much luck in finding a goo
I think that all of the big industrial automation suppliers have moved
to some variant of Ethernet. Siemens has Profinet, Allen Bradley has
Ethernet IP, Allen Bradley was using Sercos and is moving away from it.
I think that is saying a lot. I've used Siemens Ethernet solution
and it is fa
Hardware for master is hard to find because you don't need it. Any normal
Ethernet port works. Master is a software-only solution.
You can choose a simple less redundant network topology. Double ring is
used because it can tolerate failure and it's not more expensive then daisy
chain.

I have tried different hardware for real time communication and decided for the
best quality Ethercat or maybe Sercos III is the path forward.
Only real real disadvantage is they both have chosen double with two rings in
opposite direction which probably make twice as expensive as needed, one

Don't forget about the alignment of the shadow mask on those color tubes!
Modern TVs are essentially "unserviceable". New sets can be built faster
than any repair would take.
Fortunately modern sets are vastly more reliable than their predecessors.
Now manufacturers have to come up with gimmicks

I think it is more complicated that that.
I think that an analogue CRT TV is the last device that any
