Abstract

PURPOSE:To attain free of increase/decrease and replacement in number of control blocks and blocks to be controlled by adopting the constitution that plural control blocks and plural controlled blocks are connected by a supervisory control bus. CONSTITUTION:The control blocks 11,12 and the controlled blocks 21',22'-2n' are connected by the supervisory bus 3. The blocks 11, 12 monitor the state signal from the controlled blocks 21',-2n' and when the blocks 21'-2n' have an interface matching with the bus 3, the extension of the controlled blocks is recognized. Further, the replacement of the installing position of the blocks 11,12 and the blocks 21'-2n' is executed easily. Further, the bus 3 is provided with a control inhibition line and when a control block outputs a control signal, after it is confirmed that the control inhibition line is not in the inhibiting state, an inhibition signal is outputted to a control inhibition line and the control signal is outputted at the same time to connect plural control blocks to the supervisory control bus.

Description

【発明の詳細な説明】 （産業上の利用分野） 本発明は監視制御システムに関し、装置台数の増減が容
易にできる通信制御システムに関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a supervisory control system, and more particularly to a communication control system in which the number of devices can be easily increased or decreased.

難であるという欠点があった。(Problems with the Prior Art) Conventionally, as shown in FIG. 2, the supervisory control system has dedicated supervisory control lines 31, . . . , between the control block 1 and the controlled blocks 21, 22, . 32...3n, the number of interface lines has increased significantly. Therefore, as the number of monitored and controlled devices increases, it is necessary to add new monitoring and control lines, and it is difficult to change the installation locations of control blocks and add new control blocks.

It is an object of the present invention to provide a supervisory control system that allows the system to be configured.

（要施例） 次に本発明を図面により詳細に説明する。(Example required) Next, the present invention will be explained in detail with reference to the drawings.

22...2n can be easily replaced in the installation position. In addition, a control prohibition line is provided on the supervisory control bus 3, and after confirming that the control prohibition line is not in a prohibited state when outputting a control signal, the control block outputs a control signal at the same time as outputting a prohibition signal to the control prohibition line. By doing so, multiple control blocks can be connected on the supervisory control bus. In this way, multiple control blocks will receive signals from the controlled block at the same time, but only the control block with the fastest processing will output the control signal, so if one control block fails, others will receive the signal from the controlled block simultaneously. Since the control blocks operate, it is possible to construct a system that is highly reliable and does not lose its transparency.

なお、被制御ブロックが制御ブロックの機能も有してい

制御ブロックとして機能するということも可能である。Note that if the controlled block also has the function of a control block, it is possible for the controlled block to immediately function as a control block when a failure occurs in the control block.

構成であるため、制御ブロック。(Effects of the Invention) As explained above, the fifth aspect of the present invention is that the control block has a configuration in which a plurality of control blocks and a plurality of controlled blocks are connected by a supervisory control bus.

被制御ブロックの台数の増減および置換えが自由である
高信頼性システムを構成できるという効果を有する。This has the advantage that it is possible to configure a highly reliable system in which the number of controlled blocks can be freely increased/decreased and replaced.
