<p><P>PROBLEM TO BE SOLVED: To provide a plant monitoring device which narrows down for a list of PIDs necessary for monitoring, without depending on PID and placing a burden on an observer. <P>SOLUTION: Process state quantity inputted by a process input means 11 is stored, in a state quantity storage means 13, together with a process signal identifier added to a process input point. A list of data generation means 12, based on the process state quantity stored in the state quantity storage means 13, generates list of data indicating a plant state, and outputs the data through an input/output processing means 26 to an interactive device 3 for displaying. A general filtering means 20 receives a filtering condition from the interactive device 3 through the input/output processing means 26, extracts a piece of data matching the filtering condition from the list of data generated by the list of data generation means 12, and outputs the piece of data through the input/output processing means 26 to the interactive device 3 for displaying. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
