For faults with pop-up, the pop-up will be cleared when fault will be cleared or by pressing any button on the front face of the
controller. The total number of faults logged on the controller is dynamic, as the total number of “faults + alarms” is 100 (not
including the events, which are 3000 on C65 and 300 on C55) and uses a FIFO ordering.
