  However, as the number of workers increases, screen data for each worker is required, and the amount of data becomes enormous.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a screen data generation method that can reduce the amount of screen data created in advance for an operator and can ensure security.

  The problem solving means according to claim 1, a step for inputting personal authentication data, and a step of selecting screen data corresponding to the personal authentication data from a plurality of screen data stored in advance. A step of selecting only screen part data corresponding to the personal authentication data from among a plurality of screen part data included in the selected screen data, and outputting the screen data having only the selected screen part data A screen data generation method comprising the steps of:

  According to the first aspect of the invention, not only the screen data corresponding to the personal authentication data is selected, but also the screen component data of the screen data corresponding to the personal authentication data is selected. Since the screen component data that does not correspond to the personal authentication data is not output, security can be ensured.

  FIG. 1 is an example of a system configuration diagram to which the screen data generation method of the present invention is applied. The PLC 1 is a known programmable logic controller and is a control device for controlling a robot and a machine tool (not shown). The display device 2 connected to the PLC 1 is a well-known programmable display device. The display unit 2b has a touch panel for displaying the internal data of the PLC 1 and inputting data, for example, and the data and programs. And a storage unit 2c for storing. A personal computer (personal computer) 3 for registering various data necessary on the display 2 side is connected to the display 2 in the case of setup or the like. In other normal cases, the personal computer 3 is detached from the display 2.

  A plurality of screen data (for example, FIG. 2 and FIG. 3) created in advance by the personal computer 3 is stored in the storage unit 2c in the display device 2. As shown in FIGS. 2 and 3, the screen data includes background screen data and screen component data arranged thereon. For example, the screen data A in FIG. 2 includes background screen data A0 and screen component data. 3 includes screen data B including background screen data B0 and screen component data a, b, d, and e. Each of the screen data and the screen component data is provided with an image code for specifying it. 2 and FIG. 3 also serves as an image code.

  When the screen component data is displayed on the display unit 2b of the display 2, the output component has, for example, a function for displaying data (called a so-called text box), or the flag is turned on. As the input component, for example, as shown in FIG. 3 of Patent Document 1, data is obtained by pressing a portion of the touch panel of the display unit 2b where screen component data is displayed. Such as a single button or a keyboard with multiple buttons.

  In addition to the screen data, a password-image code related table (hereinafter simply referred to as a related table) shown in FIG. 4 is stored in the storage unit 2 c of the display device 2. This association table defines an image code corresponding to each password, and is created by the personal computer 3 in advance. The password is personal authentication data for authenticating the worker who uses the display device 2. The number of image codes corresponding to one password may be any number. In the association table of FIG. 4, at least four passwords “001”, “002”, “003”, and “004” are registered, and the image code “A”, “c”, “d” is stored in the password “001”. ”, The password“ 002 ”corresponds to the image code“ A ”,“ a ”,“ b ”,“ c ”, and the password“ 003 ”corresponds to the image code“ B ”,“ a ”, “B”, “d” correspond, and password “004” corresponds to image codes “B”, “d”, “e”, “c”.

  Next, the operation of the system of FIG. 1 will be described. First, the personal computer 3 is connected to the display device 2, and screen data (FIGS. 2 and 3) and a related table (FIG. 4) created in advance by the personal computer 3 are transferred to the storage unit 2c of the display device 2. When this operation is finished, the personal computer 3 is removed from the display 2. Then, a robot and a machine tool operate | move based on control of PLC1 through predetermined operation.

  The operator can confirm the control data for controlling the robot and the machine tool of the PLC 1 by the display unit 2 b of the display 2. At this time, the password input screen shown in FIG. 5 is displayed on the display device 2, and a password unique to this worker (hereinafter, described as password “001”) is input here (step S 1 in FIG. 6). Next, the CPU 2a of the display device 2 refers to the related table of the storage unit 2c and converts the password “001” into corresponding image codes “A”, “c”, and “d” (step S2). Next, the CPU 2a selects “A” screen data (FIG. 2) included in the image code extracted in step S2 from the screen data stored in the storage unit 2c (step S3). The CPU 2a includes “A”, “c”, and “d” included in the image code extracted in step S2 among the screen component data a, b, and c included in the screen data A selected in step S3. Screen part data c is selected (step S4). Next, the CPU 2a generates screen data A having only the screen component data c selected in step S4 and not having the screen component data a and b (step S5), and displaying the screen 2b as the screen shown in FIG. Is output (step S6). Therefore, the worker who has the password “001” displays a screen dedicated to himself / herself and can obtain necessary information from this screen.

  Similarly, if the operator is the password “002”, the screen data A of FIG. 2 is selected and displayed on the display unit 2b as shown in FIG. 8, and if the operator is the password “003”, the operator of FIG. If the screen data B is selected and displayed on the display unit 2b as shown in FIG. 9 and the operator has the password “004”, the screen data B of FIG. 3 is selected and displayed on the display unit 2b as shown in FIG. Is done. Therefore, screen data unique to many passwords can be generated with a small number of screen data registered in advance.

  As described above, step S1 for inputting the password (personal authentication data) and the screen data corresponding to the password among the plurality of screen data A and B stored in the display unit 2b of the display device 2 in advance are displayed. Steps S2 and S3 to select, Steps S2 and S4 to select only the screen part data corresponding to the password among the plurality of screen part data included in the selected screen data, and only the selected screen part data Steps S5 and S6 for generating and outputting screen data are provided. As a result, not only the screen data corresponding to the password is selected, but also the screen component data of the screen data is selected corresponding to the data for personal authentication, and screen data to be displayed on the display unit 2b is generated. Less screen data is required. Therefore, the storage capacity of the storage unit 2c is small, and the operator does not have to create a lot of screen data on the personal computer 3. In addition, since screen component data that does not correspond to the personal authentication data is not displayed to the worker who has input the personal authentication data, security can be ensured.

(Modification)
The present invention is not limited to that described in the embodiment. For example, the screen data generation method of the present invention is not limited to the system shown in FIG. Further, the output of the screen data is not limited to being displayed on the display unit 2b of the display device 2, but may be output to another storage device, for example. The personal authentication data may be any data that identifies an individual, and may be a user name, a fingerprint, or a combination thereof in addition to a password.

  Further, the number of screen data selected in step S3 is one in the above description, but may be plural. For example, in the above description, if screen data A including background screen data A0 and screen component data a, x, y in addition to FIG. 2 is stored in advance, two screen data A are selected. If the password “001” corresponds to the image code “B” in addition to the image codes “A”, “c”, and “d”, the two screen data A and B are selected. In this case, for example, a screen switching button may be displayed on the display unit 2b of the display device 2, and a plurality of screens may be switched in order by pressing this button. Furthermore, when the screen is switched, if it is desired to move to other screen data not included in the selected screen data, the password input screen shown in FIG. 5 may be displayed, and the password that allows the user to enter the screen again may be input.
