It had programmable firmware (via logical blocks on the programming interface) running in parallel with commands from the outside. The OS that run the firmware had race conditions with the commands received and the input so after thousands of tests the only solution was to scrap the firmware entirely and controlling the unit completely from RS232 (9600 baud, eternal) including safety stops and level photocells. [Note: safety not towards humans but towards other components of the machine, safety towards humans was managed the hard electrical way]

Also it had an encoder... on paper. Actually it counted the clock cycles the enable was "1" so if the STOP_PHOTOCELL was ignored (it happened because of the aforementioned race conditions and the fact that the photocell emitted a pulse when active and then returned to idle state) and the engine arrived to the hard stop, that is a 10kg steel block) the so called "encoder" kept counting in the direction of the movement forever and kept pushing or pulling the load against the physical block.

Straw Poll

Were you affected by the geomagnetic storms this past weekend?
Communication disruptions, electrified pipes, random unexplained blue-screens in Windows - the list of effects is terrifying.
