Hi Menno,

you should first explore the applications of redundant systems.
Then you can see, that it was definitifely not to make the same error three times.
So for redundant computer systems you must use different processors programmed in different languages from different persons.

Also if you select a device, which never assigned to be synchronized on sub machine cycles, then you can never do so.
The minimal synchronisation level, was, that you use handshake signals to wait for a certain time of full machine cycles (NOPs).

Especially for high reliable redundand systems you can never make experiments.
Exclusively such timing relations can be used, which clearly stated on the data sheet.
