It depends on the programming philosophy. On error there are all sorts of traps coded. Sometimes error handling is quite sophisticated. But a register overflow can hang a lot of machines. In some cases it passes unnoticed in millions of machines as a subtle error in calcs like the F00F bug in the Pentium that was only uncovered by December 1997. If a floating point was stored as an integer it caused an overflow and error condition. But it dit not stop the press. My guess is some controllers will halt completely and alarm until reset. The date function will have to reprogrammed by eprom or flash into some error date that can be recalced after the report to monitor systems. You cannot expect a 1 meg board packed with basic control code or machine language to be very sophisticated in analysing error conditions. Probably there are so many variables that they shutdown and alarm for safety's sake. AI in boards only goes so far. I can see plant foremen and building supers running around resetting systems all day until they put it on manual and run the place by the seat of their pants. EC<:-}
