Abstract

PROBLEM TO BE SOLVED: To prevent a dangerous editing job that imipairs the consistency of blocks, by preventing the simultaneous editing jobs which are carried out by plural display editing means and permitting the editing job of another display editing means when the simultaneous editing jobs are prevented. SOLUTION: The programs are edited in every block. The blocks, which are taken out of a store means 1 by a transmission/reception means, are sent to the display editing means 2. When a block is sent to a certain means 2, the management information on the block, which is registered by a management information register means 4, varies. Based on this management information, an editing propriety control means 5 prevents other means 2 from editing the relevant block. That is, a program editing device O never permits other means 2 to edit the block that is being edited by a certain means 2 and therefore can prevent such a case, where the editing consistency of blocks is not kept and the block operations become defective.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a program editing apparatus, and more particularly, to a program editing apparatus for editing a block program from outside using a plurality of terminals.

[0002]

2. Description of the Related Art For example, the speed of a traveling motor for driving a transport trolley or the like is controlled by arithmetic means such as a microcomputer based on a difference between a current position and a target position of the trolley. At this time, the control method, the gain function, and the like can be easily changed by modifying the program incorporated in the arithmetic means. In some cases, a program for operating the arithmetic unit is divided into a plurality of blocks that can be independently extracted in order to facilitate management of addition or change of a function. Here, FIG. 2 shows an example of a program editing apparatus for editing the above program from a plurality of externally connected terminals. As shown in FIG. The program editing device PA includes a storage unit 1 for storing a program P including blocks B (B1, B2,...) That can be independently taken out, and a plurality of display / editing devices for displaying and editing the program P. Means 2 (2a, 2
b, 2c, 2d), taking out the block B from the storage means 1 and passing it to the display editing means 2;
Transmission / reception means 3 for storing the block B edited by the display editing means 2 in the original area of the storage means 1
And In the above program editing device PA,
The storage means 1 is, for example, a storage device such as a memory or a magnetic disk incorporated in the carrier or the like. The storage means 1 is connected with a plurality of display editing means 2 for displaying and editing the program P. This connection is made by a wired or wireless communication line. The transmission / reception means 3 including this communication line takes out a block from the storage means 1 in response to a request from the display editing means 2 and transfers it to the display editing means 2. That is, the editing by the program editing device PA is performed for each block B.

The operation as a program P is performed in each block B
Is achieved by the connection of That is, each block B can include an instruction for calling another block B itself. For example, when the block B2 and the block B3 are linked, the call instruction “Call B2” for calling the block B2 itself is included in the block B3. Block B
Block B2 called by a call instruction from 3
Returns control to block B3 when its own operation is completed. Note that each block B does not call an instruction in another block B. In the editing for each block B, for example, when a call instruction in the block B3 is deleted, only the block 2 is not called and other operations are not affected. That is, each block B
Is provided so as to be taken out independently of the other blocks B. When editing block B3, for example, FIG.
As shown in FIG. 3B, the block B before editing is
3 is copied to another area. When the program is executed while the display editing means 2 is editing the block, the copied block B3c is used. When the editing of the block B is completed by the display editing means 2, the contents B edited by the transmitting / receiving means 3
3 'is returned to the original area of the storage means 1. The copied block B3c is discarded at this time. In such a program editing device PA, for example, the display editing means 2
It is possible to share the work of program editing, such as editing the block B1 by a and the block B3 by the other display editing means 2b, or to edit in a different place.

[0004]

By the way, in the program editing device PA, a program is not transferred between the storage means 1 and each display editing means 2 in real time due to a limitation of a communication line. Until the editing of the block B3 by the means 2b is completed and the edited contents are returned to the original area of the storage means 1, the edited contents cannot be referred to from the other display editing means 2a, 2c and 2d. For this reason, as shown in FIG. 4, for example, a block B3 (original contents (A, B, C)) being edited by a certain display / editing means 2b can be changed to another display / editing means 2c without knowing that it is being edited. From the block B3 edited by the display editing means 2b (A ', B, C) and the contents of the block B3 edited by the display editing means 2c (A, B, C'). Is different in spite of the same block B3, and there is a danger in the editing work, such as an attempt to delete an instruction that does not exist or to add an instruction to an incorrect location. SUMMARY OF THE INVENTION In order to solve the problems in the prior art, the present invention has improved a program editing apparatus, and has a program which can easily control the permission of editing of blocks constituting the program for each display editing means. It is an object to provide an editing device. Another object of the present invention is to provide a program editing apparatus which can easily confirm whether or not the block is being edited from another display editing means.

[0005]

To achieve the above object, the present invention provides a storage means for storing a program including blocks which can be independently taken out, and a plurality of storage means for displaying and editing the program. Display / editing means; and transmitting / receiving means for taking out the block from the storage means and transferring the block to the display / editing means, and storing the block edited by the display / editing means in the original area of the storage means. A management information registration means for registering management information relating to the editing of the block; and controlling the transmission / reception means based on the management information registered in the management information registration means. Edit permission / prohibition control means for setting whether or not the block can be edited. It is configured as a gram editing equipment. In the above program editing apparatus, the program is edited for each block. The block fetched from the storage unit in which the program is stored by the transmission / reception unit is
It is passed to the display editing means. When a block is passed to a certain display editing unit, the management information of the block registered in the management information registration unit changes.
Based on this management information, the editing permission / inhibition control means prevents other display editing means from editing the block. That is, in the above program editing device, the editing of a block being edited by a certain display editing device is not permitted by another display editing device. Therefore, the consistency of the editing of the block is not maintained unlike the conventional device. It is possible to prevent a situation in which the operation of the block becomes defective or the like.

[0006] In the program editing apparatus, the management information registered in the management information registering means includes, for example, an identifier for identifying each display editing means. Using this identifier, the editing permission / non-permission control unit permits only the display editing unit whose identifier is registered in the management information registration unit to edit the block.
When the editing of the block is completed and the block is returned to the original area of the storage unit, the registered identifier of the display / editing unit is deleted from the management information registering unit, and the block is deleted. Can be edited from the display editing means. Further, it is also possible to display on the other display / editing means which display / editing means is currently editing the block by using the identifier. Further, when the management information registered in the management information registration means includes, for example, a block content change counter which is counted up each time the block is edited, the editability control means sets the block content change counter to Based on the value of the counter, information on whether or not the block has been edited can be displayed on the display / editing means to inform the operator of the current editing status.

[0010]

[Embodiment] In the above-mentioned embodiment, when the display / editing means 2 is not permitted to edit, a message such as "edit not possible" is displayed. On the basis of the ID of the display / editing means, a message such as "currently being edited by the display / editing means 3" is displayed to indicate which display / editing means 2 is currently editing the block B. It may be. If the above-mentioned message is used, for example, when the program is being shared, the operator can also guess the content of the editing from the message, so that the editing work is further smoothed. In the above embodiment, a message such as "changed" is displayed on the display editing means 2 with reference to the block content change counter, and the display content is updated by the operator by key operation or the like. The display content may be automatically updated with reference to the value of the block content change counter. In addition, the program does not need to be divided into blocks B, and the part to be edited only needs to include blocks that can be independently processed. Such a program editing device is also an example of the program editing device in the present invention.

[0011]

As described above, according to the program editing apparatus of the present invention, a block included in a program is prevented from being simultaneously edited by a plurality of display / editing means.
