Next, a fifth embodiment of the present invention will be described with reference to FIGS.

FIG. 19 is a constitutional view of a display device showing a fifth embodiment of the present invention. In FIG. 19, the same reference numerals as those in FIG. 22 showing the conventional example indicate the same or corresponding portions, and FIG. 22 is different from FIG. 22 in that a screen copying section 49 including a variable data counting means 50, an input value storing means 51, an input value table 52 and a screen copying means 53 is additionally provided in FIG.

The variable data counting means 50 counts all variable data display amounts which can be displayed on the corresponding CRTs 1 and 2 by referring to the screen database 11 when the screen number is notified from the screen selecting means 7 and 8. is there. The input value table 52 captures and saves the value of the display point from the plant database 13. The screen copying means 53
When the input data amount is counted and the total input data amount exceeds the total variable data display amount, the screen data is copied so that the value of the display point at that time is displayed on the adjacent CRTs 1 and 2, and the screen display means 9, It is output to 10.

First, the operator touches the screen number of the requested screen while looking at the menu screen displayed on the CRT 1 or CRT 2 by operating the screen selection panel 5 or the screen selection panel 6. The touched screen number is output to the screen selecting unit 7 or the screen selecting unit 8 as coordinates on the touch screen 3 or the touch screen 4. The screen selection means 7 or the screen selection means 8 searches the touch coordinate table 12 with the input coordinates, extracts the screen number of the corresponding screen, and outputs it to the screen display means 9 or the screen display means 10.

In the screen display means 9 or the screen display means 10, the screen database 11 is searched from the inputted screen number, the screen data of the screen selected by the operator is taken out and displayed on the CRT 1 or CRT 2, and the plant database 13 or the input is made. Data is periodically fetched from the value table 52 and the variable data on the screen is displayed and updated. Further, in the screen selecting means 7 or the screen selecting means 8,
The retrieved screen number is output to the variable data counting means 50.

The variable data counting means 50 retrieves the screen database 11 from the input screen number and retrieves the ID of the input point assigned to the variable data of the screen selected by the operator. Further, the screen database 11 is searched, and the set number of collected data points is taken out as a variable data number from the information of the screen selected by the operator. The input point ID and the variable data number are stored in the input value storage means 5.

Next, the operation of the variable data counting means 50, the input value storing means 51 and the screen copying means 53 will be described with reference to FIGS. 20 and 21.

For example, when the values in the plant database 13 are displayed in a trend graph as shown in CRT1 or CRT2 as shown in FIG. 21, only the CRT1 displays the screen of the trend graph at the current time, and another screen is displayed in the CRT2. It is supposed to be displayed. The screen of the trend graph is composed of fixed data such as the X-axis and Y-axis and variable data of the graph body as shown by screen data 54 of the copy source.
The trend graph shown in this example can plot six data as variable data.

The variable data counting means 50 counts the number of variable data portions (S41). The input value storage means 51 periodically retrieves the values of the input points of the trend graph from the plant database 13 and accumulates them in the input value table 52. Further, the input value storage means 51 compares the number of input point values accumulated in the input value table 52 with the number of variable data portions of the copy source screen data 54 (S42).

Now, when the values of six input points are accumulated in the input value table 52 as shown in FIG. 21, when the values of the input points are further input from the plant database 13, the input value storage means It is determined by 51 that the number of variable data portions exceeds, and the screen copying means 53 copies the copy source screen data 54 and copies the copy destination screen data 5.
5 is created (S43, S44). In this case, as the copy destination screen data 55, the fixed data portion of the copy source screen data 54 is copied as it is, and the variable data portion is copied as much as it overflows from the copy source screen data 54.

Next, it is determined whether or not the screen can be displayed on the CRT adjacent to the right side based on the current CRT (S).
45). If the screen can be displayed, the screen data of the copy destination is newly displayed on the CRT on the right side, and the process ends (S46).

On the other hand, if the screen cannot be displayed, it is determined whether the screen can be displayed on the CRT adjacent to the left side based on the current CRT (S47). If the screen can be displayed, the screen data of the copy source is newly displayed on the left CRT (S48). Next, when the screen cannot be displayed on the CRT adjacent to the left side, the screen data of the copy destination is displayed on the current CRT and the process ends (S49).

As described above, according to the fifth embodiment of the present invention, in the conventional display device, the screen in which the amount of data to be displayed is variable, for example, the trend graph screen in which the data for one hour can be plotted can be displayed. If the amount of collected data exceeds 1 hour while displaying, scroll the entire graph to erase the oldest plot and assign that amount to the latest plot, or increase the scale of the graph. It was necessary to switch to the unit and redisplay the entire graph.

However, in the method of scrolling the graph, if one wants to see the old data that has been erased, he cannot immediately see it, and in the method of switching the scale of the graph, the graph itself becomes smaller. However, there was a problem that the accuracy of the graph would drop. In this display device, when the amount of data to be displayed is variable like the trend graph screen, when the input data exceeds the displayable data amount, the same screen is displayed on another CRT, and the screen is displayed. By displaying after
It can be displayed without degrading the accuracy of the graph.

For example, CRT1 and CRT are displayed on the display device.
It is assumed that two CRTs (2) are connected and a trend graph screen that can plot 1 hour's worth of data in 1 minute units is displayed on CRT 1. Now, assuming that exactly one hour has passed since the start of data collection, the data is plotted on the trend graph displayed on the CRT1 in a scale of one hour. Next, one minute has passed from that point, and when the next data is collected, the trend graph displayed on the CRT 1 cannot afford to plot that data. In such a case, the same screen as the trend graph screen displayed on CRT1 is displayed on CRT2,
By displaying the collected data on the trend graph screen of CRT2, when CRT1 and CRT2 are viewed as one graph, data for two hours can be displayed without lowering the accuracy of the graph.

As described above, when the input data amount exceeds the variable data amount of the currently displayed screen, the subsequent screens are displayed on the CRT so that they are adjacent to each other. Can be reduced, the burden on the operator can be reduced, and the trend graph and the like can be continuously displayed on a plurality of CRTs without lowering the accuracy.
