TECHNICAL FIELD OF THE INVENTION
The present invention relates to a display device, and more particularly to a display device suitable for displaying input / output contact information and the like in a desired range of a production facility displayed in three-dimensional graphics.
[0002]
[Prior art]
2. Description of the Related Art In recent years, devices that simulate production equipment using three-dimensional graphics have become widespread.
[0003]
This is a model that can model the shape, operation, I / O signal (input / output contact signal), etc., and simulate the movement and state of the device in the same way as the real thing in order to display 3D graphics as a model of production equipment It is. Three-dimensional graphics are provided in advance as a means for facilitating simulation design such as model creation and logic verification.
[0004]
By the way, in these devices, information is managed in units of devices and objects, but since the I / O information is a signal connecting the devices and objects to each other, they are separately managed in a separate database.
[0005]
This is because the unit of a device or an object is a unit of a simulation model, has a physical shape, and can be displayed in three-dimensional graphics. However, since I / O information is a signal connecting devices and objects to each other, This is because they have no shape and cannot be displayed in three-dimensional graphics.
[0006]
Therefore, when it is desired to obtain I / O information of a part of a production facility displayed in three-dimensional graphics, a part of the production facility displayed in three-dimensional graphics is specified on a screen using a pointing device such as a mouse. In this case, the I / O information of the specified device is displayed. In this case, the I / O information is displayed in, for example, a table format.
[0007]
[Problems to be solved by the invention]
However, in the conventional apparatus as described above, the I / O information of the specific device specified by specifying the specific device of the production facility displayed in three-dimensional graphics on the screen with a pointing device such as a mouse is used. Although the display is performed, the display of the I / O information is a display for each device. This is because a specific device is specified by instructing a picture of a specified portion on the screen with the pointing device, and all I / O information of the specified component is displayed.
[0008]
In a production facility using a control device such as a programmable controller, an output signal to an actuator device such as a motor is obtained based on input signals from various sensors. In creating a user program for the programmable controller, input / output contacts (I / O) are defined, a timing chart for the input / output contacts is created, and a user program is created to match the timing chart. Therefore, in a production facility using a control device such as a programmable controller, it is very important that unnecessary I / O information can be eliminated and only I / O information of a necessary portion can be arbitrarily extracted. .
[0009]
SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and a purpose thereof is to eliminate unnecessary I / O information and arbitrarily extract and display only necessary I / O information. It is an object of the present invention to provide a display device capable of performing the following.

[0025]
Next, the contents of the input data table 40 and the output data table 41 stored in the I / O information database 12 will be described with reference to FIGS.
[0026]
The input data table 40 shown in FIG. 4 includes an I / O number column 40-1, a signal name column 40-2, a status column 40-3, and an initial value column 40-4.
[0027]

[0028]
The signal name column 40-2 stores the names of signal lines (for example, corresponding to the signal lines 31, 32, 33, 34, 35, and 36 in FIG. 2) for connecting each input contact to the programmable controller. For example, the first signal names “RO_IN0 to RO_IN4” represent the names of input signal lines from the robot arm to the programmable controller.
[0029]
The status column 40-3 indicates whether each signal line is ON = 1 or OFF = 0, and changes with time.
[0030]
The initial value column 40-4 stores an initial value of each signal line when the equipment is operating.
[0031]
Next, the output data table 41 shown in FIG. 5 includes an I / O number column 41-1, a signal name column 41-2, a status column 41-3, and an initial value column 41-4.
[0032]

[0033]
The signal name column 41-2 stores the names of signal lines (e.g., corresponding to the signal lines 31, 32, 33, 34, 35, and 36 in FIG. 2) for connecting each output contact to the programmable controller. For example, the first signal name “RO_OUT0, RO_OUT1” indicates the name of an output signal line from the programmable controller to the robot arm.
[0034]
The status column 41-3 indicates whether each signal line is ON = 1 or OFF = 0, and changes with time.
[0035]
The initial value column 41-4 stores the initial value of each signal line when the equipment is operating.
[0036]
The configuration is as described above. Next, a processing procedure for displaying only I / O information in a desired range in the present embodiment will be described with reference to the flowchart of FIG.
[0037]
In this process, the user places the mouse cursor at the starting point with the mouse 18 while looking at the three-dimensional graphics display of the production facility 15 displayed on the display 16 as shown in FIG. 2 (step 100).
[0038]
Next, the designated range is surrounded from the start point while holding down the left button of the mouse 18 (step 102).
[0039]
Next, the center of gravity A of the specified range is calculated (step 104).
[0040]
Next, the maximum value of the distance from the center of gravity A to the line in the specified range is obtained, and a sphere having this value as the radius is calculated (step 106).
[0041]
Next, based on the calculated sphere, a polyhedron including a specified range centered on the center of gravity A is calculated, and the boundary surface of the polyhedron is displayed as a surface model (step 108).
[0042]
Next, while checking the surface model displayed on the display 16, it is checked whether or not the necessary range has been surrounded by the processing of steps 100 and 102 (step 110).
[0043]
Here, if it is determined that the necessary range is not enclosed (NO in step 110), the boundary surface is moved using the mouse 18 so that the boundary is properly enclosed (step 112).
[0044]
Here, it is checked again whether or not the necessary range has been correctly enclosed (step 114). If it is not determined that the necessary range has been correctly enclosed (NO in step 114), the process returns to step 100.
[0045]
On the other hand, if it is determined in step 110 that the required range has been enclosed (YES in step 110), and if it is determined in step 114 that the required range has been enclosed (YES in step 114), the process proceeds to step 116.
[0046]
In step 116, it is checked whether or not all the signal lines of the input / output contacts in the boundary (polyhedron) intersect at the boundary (step 116).
[0047]
Here, when all the signal lines do not intersect at the boundary surface (NO in Step 116), the process returns to Step 100.
[0048]
On the other hand, if all the signal lines intersect at the boundary surface (YES in step 116), a selection list is created using the signal names of the intersecting signal lines as IDs. This refers to the I / O information database 12 and the I / O based on the signal name of the crossed signal line while referring to the signal name columns 41-1 and 41-2 of the output data table 41. This is a process of creating a selection list of O information.
[0049]
Next, input / output contacts connected to each signal line are selected based on the selection list created in step 118, and the input data table 40 and the output data stored in the I / O information database 12 at that time are selected. An I / O information list is created with reference to the data stored in the table 41 (step 120).
[0050]
Thus, only the desired range of I / O information can be obtained by a simple operation of surrounding the desired range for obtaining I / O information with the mouse 18.
[0051]
FIG. 7 is a display example in the case where a polyhedral boundary surface 50 is set in a part of the production facility displayed in the three-dimensional graphics shown in FIG. Only the / O information will be obtained.
[0052]
Next, a display example of the obtained I / O information will be described with reference to FIGS.
[0053]
FIG. 8 shows a display example when the I / O information is obtained in the form of a time chart.
[0054]
As shown in the figure, only the I / O information of the input / output contacts within the boundary surface 50 is displayed over time as ON = 1, OFF = 0 information of the signal line connected to the input / output contacts.
[0055]
FIG. 9 is a display example when the I / O information is obtained in the form of a table as the input / output data table 60. The input / output data table 60 includes an I / O number column 60-1, a signal name column 60-2, a status column 60-3, and an initial value column 60-4.
[0056]
As described above, in the present embodiment, only the I / O information in the desired range can be obtained by a simple operation of surrounding the desired range in which I / O information is to be obtained with the mouse 18.
[0057]
【The invention's effect】
As described above, in the present invention, the display device displays the operation status of the production facility having the input / output contacts by the three-dimensional graphics display of the production facility, but when displaying the contact information of the input / output contacts, first, Since a part of the production equipment graphically displayed by the specifying means is specified by the enclosing means, and then the display means displays the contact information of the input / output contacts within the range specified by the specifying means, This has an effect that unnecessary I / O information can be eliminated and only desired I / O information can be arbitrarily extracted and displayed.
