<p>PROBLEM TO BE SOLVED: To provide a monitoring device with which the retrieval of an operator is reduced by suppressing useless printing output and reducing useless history messages. SOLUTION: This device is composed of an input/output signal data base 3 in which the presence/absence of checks and the kinds of checks are registered by a check equipment register part 2, an event input part 4 for inputting the states/faults/operate signals of respective pieces of equipment, and a history message judge part 5 for judging whether the history message is to be preserved in a check history preservation part 6 for preserving the history message or in a history message preservation part 8 for preserving ordinary messages excepting for a check history corresponding to an input signal from the event input part 4 and the presence/absence of checks in the input/output signal data base 3. In this case, the ordinary message is preserved in a history data base 10 and outputted from a history message output part 9, and the message concerning check object equipment is preserved in a check history data base 7 and outputted from a check history message output part 12 to a printer. Therefore, the retrieval of the operator can be reduced by suppressing useless printing output and reducing useless history messages.</p> |
