<p>PURPOSE:To obtain the facility operation state display device which detects abnormality due to transient variation, detects abnormality as to all input/output points, and displays secular change. CONSTITUTION:This facility operation state display device consists of a means 101 which is stored with the address of an operation command signal and the address of an operation end signal and also stored with information showing that the operation command signal is outputted and the operation end signal is sent back, a means 102 which sets conditions for judging abnormal state occurrence, a means 103 which monitors the stored states and decides whether or not abnormality occurs from whether or not the conditions are satisfied, a means 104 generates a command for holding the stored states when the abnormality occurs, a means 105 which reads control logic out, a means 106 which synthesized the held operation state information and control logic information, and a means 107 which displays the synthesized information as the secular change.</p> |
