The present invention relates to an easy plant monitoring control program.

In plant monitoring and control systems that monitor and control plants such as waterworks and sewerage facilities, there are always manned monitoring stations where there are supervisors and supervising control, and usually no supervisors are stationed. There is an unmanned monitoring station where a supervisor visits and controls only when necessary. Whether to use a manned monitoring station or an unmanned monitoring station is determined according to the monitoring control contents of the plant, and a corresponding plant monitoring control device is installed.

When the output component 5a is selected to create the plant monitoring control program 16 and the like, the input definition file 7a incorporated in the plant monitoring control program 1 and the like together with the input components 3a to 3c, the calculation components 4a and 4b, and the output component 5a To 7c, the calculation definition files 8a and 8b, and the output definition file 9a specify the data input / output destinations of the input components 3a to 3c, the calculation components 4a and 4c, and the output component 5a, and these input components 3a to 3c are chained. Since the calculation parts 4a and 4c and the output part 5a are connected to determine the data processing order, the plant monitoring control process A plurality of input programs, a plurality of arithmetic programs, a plurality of display programs, a plurality of output programs, and the like, which are obtained by modularizing each of the input components 3a to 3n, the respective arithmetic components 4a to 4n, and the respective output components 5a to By simply describing the 5n connection relationship, it is possible to specify the data processing order without creating a program in accordance with the temporal flow, and to greatly reduce the program manufacturing cost, the time required for manufacturing, and the like.
