[Prior Art]

 FIG. 4 is a block diagram of a control device equipped with a programming device (hereinafter referred to as P.P.) shown in the catalog of the programming device "MELSEP 1100 Maintenance Panel" for Mitsubishi power plant, for example. In the figure, 1 is P.P. and 2 is a control device. 11 is a CRT, 12 is a keyboard (hereinafter referred to as K / B), 13 is control program creation software for converting image data of a control program created using the CRT 11 and K / B 12 into machine language, 14 Is the memory capacity definition software that defines the usable memory capacity of the control program, 15 is the control symbol machine language memory software, 17 is the control program created by the control program creation software 13, and 18 is the control program. Is a memory capacity storage area defined by the control program memory capacity definition software 14, 19 is an actual memory capacity storage area that is actually used by the control program 17, and 20 is a controller I for communicating with the controller 2. / F software. Further, FIG. 5 is an internal processing flow of P.P.1.

Next, the operation will be described. In P.P.1, image data for the control program is created by drawing control symbols using the K / B12 on the CRT11 screen. First, the control program memory capacity definition software sets the defined memory capacity in the control program definition memory capacity storage area (ST-1). Next, 0 is set in the control program real memory storage area (ST-2). Then, the control program definition memory capacity and the actual memory capacity are displayed on the CRT 11 (ST-3). The control program creation software 13 obtains data from the CRT 11 and K / B 12 (ST-4), judges the data, and (ST-5) returns to (ST-4) again if editing is not completed and edits. Continue. When the editing is completed, the created image data is converted into the control program 17 with reference to the control symbol machine language storage software 15 to obtain the control program actual memory capacity. (ST-6). Then, it is compared with the control program definition memory capacity storage area 18 (ST-7). If there is more, an error message indicating insufficient memory is displayed on the CRT 11 (ST-8) and the process returns to (ST-4). If it is small, the control program real memory capacity is added to the control program real memory capacity storage area 19 (ST-9). When (ST-9) is completed, the control program 17 is transmitted to the control device 2 via the control device I / F software 20.

[0004]

[Problems to be solved by the device]

 Since the conventional programming device is configured as described above, in order to obtain the actual memory capacity of the created control program, it is necessary to convert the image data of the control program into the control program of the machine language. However, there was a problem that when the memory capacity became insufficient after the end of the compilation, the editing had to be redone.

The present invention has been made to solve the above problems, and the actual memory capacity of the control program can be easily obtained at the editing stage of the control program, and the remaining amount of the control program remains. By creating a control program while observing the CRT display of the memory capacity, the purpose is to avoid re-editing after editing the control program due to insufficient memory.

[0006]

[Means for Solving the Problems]

 The programming device according to the present invention stores the memory capacity of each control symbol in the storage device, reads the selected memory capacity of each control symbol from the storage device, displays the CRT, and registers or deletes the control program. And the control program remaining memory capacity obtained from the control program actual memory capacity and the defined memory capacity are displayed on the CRT.

[0007]

[Action]

 The programming device according to the present invention displays the memory capacity of the symbol selected during creation and editing and the remaining memory capacity of the control program calculated each time the symbol is registered or deleted, thereby controlling the memory capacity while referring to the memory capacity. You can create and edit a control program, and after editing the control program, there is no need to re-edit due to lack of memory.

【Example】

 Example 1. Hereinafter, this embodiment will be described with reference to the drawings. In FIG. 1, 1 is P.P. and 2 is a control device. 11 is a CRT, 12 is a keyboard (hereinafter referred to as K / B), 13 is a control program creation software for converting the image data of the control program created using the CRT 11 and K / B 12 into machine language, and 14 is Memory capacity definition software that defines the usable memory capacity of the control program 15 is the control symbol machine language storage software, 16 is the total control symbol memory capacity storage software, and 17 is created by the control program creation software 13. Control program, 18 is the memory capacity storage area defined by the control program memory capacity definition software 14, 19 is the actual memory capacity storage area actually used by the control program 17, and 20 is the controller 2 It is a control device I / F software that communicates with. FIG. 2 is a flow chart of the internal processing of P.P.1 and FIG. 3 is a control screen when editing the control program of P.P.1. When this control program is executed, all the arithmetic processing displayed on the screen is executed.

Next, the operation will be described. In P.P.1, image data for the control program is created by drawing control symbols using the K / B12 on the CRT11 screen. First, the control program memory capacity definition software sets the defined memory capacity in the control program definition memory capacity storage area (ST-1). Next, 0 is set in the control program real memory storage area (ST-2). Then, the control program actual memory storage area 19 is subtracted from the control program definition memory capacity storage area 18 (ST-3), and the obtained control program remaining memory capacity is displayed on the CRT (ST-4). The control program creation software 13 obtains data from the CRT 11 and K / B 12 (ST-5), judges the data, and (ST-6) registers control symbols, or if deleted, all control symbol individual memories. The control symbol memory capacity is obtained from the capacity storage software 16 and displayed on the CRT (ST-7). It is judged whether the control symbol is registered or deleted (ST-8). If it is registered, the control symbol memory capacity is added to the control program actual memory capacity storage area 19 (ST-9), and if deleted, it is subtracted (ST-9). ST-10). When (ST-9) or (ST-10) is completed, (ST-3) is executed again. When it is judged that the editing of the control program is completed in (ST-6), all the control symbols are converted into the control program 17 with reference to the machine language storage software 15, and the control device I / F software 20 is used. Is transmitted to the control device 2.

Example 2. In the above embodiment, the case where the control symbol memory capacity and the control program remaining memory capacity are displayed on the CRT has been described. However, the control symbol memory capacity, the control program definition memory capacity, and the control program actual memory capacity are displayed on the CRT. The same effect can be obtained by displaying on.

[0011]

[Effect of the device]

 As described above, according to the present invention, the programming device stores the memory capacity of each control symbol, reads out and calculates the memory capacity of the control symbol used for the control program, and the remaining memory during the creation of the control program. Since the control program can be created while displaying the capacity and referring to it, the control program remaining memory capacity can be easily obtained from the control program editing stage. This has the effect of eliminating re-editing due to lack.
