Controller Fault Handler

This routine allows the machine or process to ignore major PLC faults that could happen while operating. For instance, if a timer gets a negative preset or an array goes out of bound, the fault can be ignored. This would allow the machine or process to keep running without taking the PLC out of run mode. Normally this type of fault would halt the processor, immediately stopping the machine or process.

The bit on the left can be manually toggled on/off to ignore the selected alarm (if desired).
