Abstract

The editing of a sequence program becomes easier using a combination of a ladder diagram system and a mnemomic system. First of all, a screen is selected (Step S1) either for displaying only a ladder diagram or for displaying both a ladder diagram and a mnemonic program. When only one signal is edited, the graphic screen is selected (Steps S7 to S9), and when a plurality of signals are edited by one net, the mnemonic screen is selected (Steps S2 to S6). When the mnemonic program is edited, the corresponding ladder diagram is edited, too. When an escape (ESC) key is pushed (Step S11), the editing is completed. By the combination of the ladder graph system and the mnemonic system, the selection of a program of a desired net can be made on the ladder diagram, while a definite editing operation can be made by the mnemonic system.

Description

Description Sequence ・ Program editing method

The present invention relates to a sequence program editing method for editing a sequence program on a screen, and more particularly to a sequence program editing method that combines a ladder diagram format and a mnemonic format. Background technology

Conventionally, there are two methods of editing a sequence program: a method of displaying a program in a ladder diagram format on a display screen of a programming device, and a method of displaying a program in a mnemonic format on a command line.

In the case of the ladder diagram format, edit the cursor by moving the cursor to the signal display (element) of the contact or coil to be changed and changing the new address or symbol.

On the other hand, in the case of the mnemonic format, the user specifies the net program containing the signal to be edited with a key, calls it on the command line, and edits the data of the desired signal.

However, in the ladder diagram format, only the signal currently specified by the cursor could be edited. Therefore, when editing a plurality of contact points, it was necessary to repeat the cursor alignment and key input, resulting in poor operability.

In the case of the 21-monic format, the desired net is called. In order to issue it, it was necessary to specify the net ban by key input, and it was necessary to check the ban. Therefore, the operability is reduced to j§.

The present invention has been made in view of such a point, and an object of the present invention is to provide a sequence / program editing method that improves operability by combining a ladder diagram format and a mnemonic format. And

In the present invention, in order to solve the above-mentioned problems, in a sequence / program editing method for editing a sequence program on a screen, a ladder diagram format program is displayed on the screen, and the ladder diagram format is displayed. Specifying a program to be edited on the program, displaying a 21-monic format program corresponding to the specified ladder diagram format program on the same screen, and editing the 21-monic format program. A special sequence and program editing method is provided.

When a desired program is specified on a ladder diagram format program, a mnemonic format program corresponding to the specified program is displayed on the same screen for editing. Therefore, while a desired program can be selected on the ladder diagram, specific editing can be performed in a mnemonic format. Brief explanation of drawings

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a block diagram of a programming device for implementing the present invention. The programming device 1 is configured around a processor 2. A program memory 3 and a data memory 4 are connected to the processor 2 via a bus 5. The program memory 3 stores a system program for causing the programming device 1 to function. The data memory 4 stores the sequence program created by the programming device 1. This sequence program is stored in object format and is displayed on the screen in mnemonic format and ladder format.

Sequence ♦ The program is input from the keyboard 6 and displayed on the display device 7. In addition, the sequence ♦ program can be edited with the mouse 8 or printed out to the printer 9. Further, the sequence ♦ The program may be stored in the hard disk device 12 which is an external memory. The created or edited sequence program is stored in data memory 4. Via the interface 10 to the ROM writer 11 where it is written to the ROM. If necessary, the ladder program can be read from the PMC RAM without removing the RO RO from the PMC (Program Machine Con- troller). In this case, the exchange of data is performed via the interface 13.

FIG. 3 is a schematic diagram of the keyboard 6 and the display device 7. Display device? The display screen Ίa shows the sequence / program being created or edited. Further, a menu display section 70 is provided below the display screen 7a. The menus 71 to 78 displayed on the menu display section 70 are switched at any time according to the display contents of the display screen 7a. Selection of these menus 7 1 to 7 8 is performed by the function keys 60 of the keyboard 6. The keys 6 1 to 6 8 of the function keys 60 correspond to the menus 7 1 to 7 8 in a one-to-one correspondence. For example, when the key 61 is pressed, the menu 71 is selected. It has become so. The keyboard 6 is provided with character keys 8 1 and numeric keys 8 2 for use in inputting and editing of a sequence and a program. The keyboard 6 is provided with a return key 83, an escape (ESC) key 84, a cursor key 85, and the like. Next, a specific procedure of the editing method of the sequence program σ-program according to this embodiment will be described. FIG. 4 is a diagram showing a graphic screen 91 which is one of the editing screens. The graphic screen 91 includes a ladder diagram 86 and a menu display section 70. Also, a command line 87 is provided between the ladder diagram 86 and the menu display section 70. Figure 8 6 shows the scrolling of the screen. The desired net can be displayed. The menu display section 70 displays the contact points required for graphic editing, such as symbols such as coils, and other menus 71 to 78. In this menu display section 70, a mnemonic screen selection menu 77 and a graphic screen selection menu 78 are displayed. The graphic screen 91 in FIG. 4 is displayed by pressing the function key 68 in FIG. 3 and specifying the graphic screen selection menu 78.

If you want to edit only signal 86a, move cursor 88 to signal 86a. The cursor 88 can be set for each signal, that is, for each element of the ladder diagram. If it is desired to modify the data of the signal 86a from, for example, XI 2.3 to XI 2.5, enter the data X 12.5 with the keyboard 6. (However, X12.3 and X12.5 indicate the address.) The data entered by this key is displayed on the command line 87. If you want to confirm this new data, press return key 83. As a result, the sequence program in the data memory 4 is converted as displayed, and the data is internally determined. To change the symbol of signal 8Pa, select one of menus 71 to 74. To make this selection, press the corresponding key among the function keys 61 to 64. As an example, specify menu-72 here. Then, press the return key 83 to confirm this data. This internally edits the data. FIG. 5 is a diagram showing the edited graphic screen 91. As can be seen from the figure, the display of the data and the symbol of the signal 86a has also been converted. As described above, when editing data of a part of the signal, it can be easily performed on the graphic screen 91. However, when editing a plurality of signals on the same net, it is necessary to repeat cursor positioning, return key input, and the like, and input errors are likely to occur. Therefore, in this embodiment, when editing a plurality of signals on the same net, the display screen 7a is switched to the 21-monic screen 92 to perform the editing. That is, the function key 67 of the keyboard 6 is pressed to specify the mnemonic screen selection menu 77. As a result, the display screen 7a is switched from the graphic screen 91 to the mnemonic screen 92 in FIG. When the screen is switched to the 21 monic screen 92, the cursor 88 moves to the command line 87. The net carrying the signal 86a is surrounded by a line 93, and the line 93 is highlighted.

The program of the net surrounded by the line 93 is displayed on the command line 87 as a mnemonic program 89. The operator corrects the character or number at the position of the cursor 88. If you do not need to make any corrections, use the cursor keys 8 5 to move the force-sol 8 8 to the next position you want to correct. For example, the data RX12.3 (READ X12.3) of the signal 86a is converted to the RX12.5 (READX12.5), and the data AR2.3 of the signal 86b is converted. (AND R 2.3) to AN R 4.5

If you want to modify it to (AND. OT 4.5), place the cursor 88 below the character or number to be converted and enter new data using the character keys 81 or ten keys 82. To confirm these new data, press return key 83. As a result, the sequence program in the data memory 4 is displayed. The data is converted and the data is edited internally. When the cursor 88 is moved on the command line 87, the return key 83 may be kept pressed instead of the cursor key 85.

FIG. 7 is a diagram showing the mnemonic screen 9 after editing. As can be seen from the figure, not only the program 89 on the command line 87 but also the data of the signals 86a and 86b in the ladder diagram 86 are rewritten. In this way, to continue editing within the same net surrounded by line 93, it is sufficient to edit continuously on command line 87, and finally press return key 83 . Alternatively, the return key 83 may be pressed each time a character or a number is input one by one. If the user wants to edit the signal of another network, he or she can select the graphic screen 91 again and perform the same operation. To end editing, press ESC key 84 to end it.

FIG. 1 is a flowchart for explaining the processing procedure of the sequence / program editing method of this embodiment. This processing is started when the display screen 7a is selected as the graphic screen 91 or the mnemonic screen 92. The number following S indicates the step number.

[S1] It is determined whether or not the mnemonic screen 92 has been selected, and if so, the flow proceeds to step S2, and if the graphic screen 91 has been selected, the flow proceeds to step S7.

[S2] A net including the signal specified by the cursor 88 is surrounded by a line 93, and the line 93 is highlighted.

Wait for CS43 data to be input.

CS53 Determines whether or not to edit the keyed data internally, that is, whether or not return key 83 was pressed after data input. If the return key 83 is pressed, proceed to step S6; otherwise, that is, if the function key 68 is pressed, the screen selection is switched to the graphic screen 91, or ESC. When the key 8 is pressed to end the editing, the process proceeds to step S10.

[S6] Internally edit the data entered on the 21st monic screen 9.

[S7] Wait for cursor designation of signal and input of new data of designated signal.

[S8] It is determined whether or not the keyed data is to be edited internally, that is, whether or not the return key 83 has been pressed after the data has been input. If the return key 83 is pressed, proceed to step S9; otherwise, that is, if the function key 67 is pressed, the screen selection is switched to the mnemonic screen 92 or the ESC key is pressed. When the editing is completed by pressing 8 4, the process proceeds to step S 10.

[S 9] Internally edits the data entered on the graphic screen 9 1.

C S 10] It is determined whether the function key 67 or 68 has been pressed and a screen selection has been made, and if so, the flow returns to step S1; otherwise, the flow proceeds to step S11.

[S 1 1] Determine whether ESC key 84 has been pressed and press If the confirmation is successful, the process is terminated.

Go to S12.

[S12] It is determined that a key input error has occurred, an alarm is displayed on the display screen 7a, etc., and the operator is informed of the error, and the operation proceeds to step S5.

As described above, in the present embodiment, the selection of the signal to be edited is made intuitively by performing selection on the graphic screen 91, and a plurality of signals to be edited are included in the same net as the selected signal. In some cases, editing them on the mnemonic screen 92 simplifies key entry. Therefore, operability is good.

As described above, in the present invention, when a desired program is designated on a ladder diagram format program, the corresponding mnemonic program is displayed on the same screen. The program can be selected on the ladder diagram while the specific editing can be done in mnemonic format. Therefore, operability is improved because program selection is easy to understand and key input for editing is simple.
