る。(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing a schematic configuration of the first embodiment of the present invention. The difference from FIG. 3 is that the signal name to be displayed during real-time display is automatically changed every time the real-time signal designation circuit is changed. The recording signal registration circuit is also updated and registered in the same way. That is, a first means for graphically displaying the changeable real-time signal from the real-time signal designation circuit 3, such as a graph display circuit 6, records the changeable real-time signal from the real-time signal designation circuit 3, and A second means for reproducing the recorded signal and displaying it in a graph is provided, for example, a signal recording circuit 9 and a recorded signal extraction circuit 10.

送し、記録信号登録回路８の指定を更新する。The operation of the thus configured first embodiment will be briefly described. When an operator changes a signal name while observing a real-time display graph, he changes the signal designation circuit 3 of the monitor device 2, transmits the changed data to the control device 1, and changes the designation of the recording signal registration circuit 8.

を行う。When performing real-time display, the real-time signal designation circuit 3 of the monitor device 2 transmits the requested signal name to the control device 1 every drawing period of the graph display circuit 6, and the control device 1 uses the real-time signal extraction circuit 4 to send the requested signal name to the control device 1 each time. Real-time data is taken out and transmitted to the monitor device 2 through the transmission signal switching circuit 5. The monitor device 2 displays the received real-time signal in a graph using the graph display circuit 6.

る。On the other hand, when an operator is observing a real-time display graph and wants to see a more detailed graph or see it again,
The transmission signal switching circuit 5 is switched, the recording signal of the signal recording circuit 9 of the control device 1 is extracted by the recording signal extraction circuit 10, and the reproduced signal is transmitted to the monitor device 2. The signal received by the monitor device 2 is displayed as a graph on the monitor screen by the graph display circuit 6 in the same way as the real-time signal.

作性が格段に向上することが期待できる。According to the first embodiment described above, the operator can easily switch between real-time display and recorded display by simply specifying the signal to be observed once. In other words, there is no need to configure both settings, and the real-time graph you are viewing on the monitor screen can be stopped at any time to view details or before and after, greatly improving operability. We can expect that.

The embodiment shown in FIG. 2 can turn on and off the interlocking of the recording signal designation shown in FIG. The difference is that they both include a recording signal designation circuit 7 for designating. It should be noted that components given the same numbers as in FIG. 1 are the same elements.

は明らかである。The embodiment shown in FIG. 2 differs from FIG. 1 in the following points:
The point is that the signal to be recorded can be set independently from the signal to be displayed in real time, and if necessary, which of the two settings in the monitor device should be enabled is sent to the control device 1,
Recording signal registration circuit 8 through recording signal registration switching circuit 11
can be changed. As in FIG. 1, it is possible not only to stop the graph display during real-time graph display and display its details, but also to register another signal in the recording signal registration circuit 8, When an abnormality occurs, another type of recorded signal from a different perspective can be reproduced. It is clear that switching between these two usages can be done with a simple operation, and in this embodiment, the purpose of the present invention is to record and reproduce the same signal while observing the real-time display of the same signal. It is the same in that the signals can be designated at once, and it is clear that this does not contradict the gist of the present invention.

Therefore, it is possible to provide a monitoring system for a control device that improves operability.
