<p>PURPOSE:To constitute the computer with a system reset function so that it is prevented that system reset is applied easily in the course of on-line, and also, forced system reset is applied without an error when necessary. CONSTITUTION:This computer is constituted so that in the case system reset is instructed by user reset 2, in a flip-flop(FF) 55 of an alarm controller (ACU) 31, unless a state of system-OFF is detected and held as '1', based on a system on-line signal from a system control unit(SCU) 12, a system reset signal passing through an AND gate (AND) 34 is not outputted, and on the other handy in a state of system-ON that data '0' is detected and held in the flip-flop(FF) 55, unless system reset is instructed simultaneously by user reset 1 and 2, a system reset signal passing through an AND gate (AND) 55 is not outputted.</p> |
