The thing with EtherCat is that the setup process is relatively
complicated wrt. running the control loop when it is finally set up.
Why not write the setup in a scripting language like Python to then
pass control to a RT core in C running e.g. on RTLinux or even on a
RTOS / state machine ARM.

With BeagleBones selling at $45 these days, it seems that from now on
it makes a lot of sense to split applications into a "compiler" part
running on a Linux host, and a core statemachine part running on the
bare micro.
