To get the equipment key. As a result of the search, it is determined whether there is a search error. If YES, an error is displayed in S92. On the other hand, in the case of NO, since the equipment key can be obtained by searching, the process proceeds to S82.

S82 is a DB request section (client) 2
3 creates a command [Delete equipment key]. In S83, the communication processing unit (client) 22 transmits the command created in S82 to the processing device (server) 11 via the communication network.

In S84, the communication processing unit (server) 13
The command transmitted in S83 is received. In S85, the DB processing unit (server) 12 secures an exclusive lock. And
The equipment drawing database 1 is searched with the equipment key. S86
If it is YES, a return code abnormality is set in S93, and if NO, the process proceeds to S87.

In step S87, it is determined whether or not the exclusion flag has been set. If it has already been determined, it has been found that exclusion has already been acquired, and therefore an error is set in the return code in S94. on the other hand,
If not, the corresponding record is deleted from the equipment drawing database 1 in S88. Set a return code. Then, in S89 of releasing the exclusive lock, the communication processing unit (server) 13 transmits a return code.

In S90, the communication processing unit (client) 2
2 receives the return code. In S91, the display processing unit (client) 24 determines whether the return code is normal or abnormal. If normal, the equipment key and the drawing information are deleted from the display memory, and the figure is output from the drawing information to the display device. On the other hand, if there is an abnormality, an error is displayed in S95.

As described above, in response to the instruction of the equipment to be removed on the screen, the record of the equipment to be removed is deleted when the exclusive flag 6 of the designated equipment key is not present, and also deleted from the screen. This makes it possible to specify the equipment to be removed on the screen and delete the corresponding record from the equipment drawing database 1. FIG. 11 shows an equipment removal explanatory diagram of the present invention.

FIG. 11B shows an example of the screen of the equipment correction process. (B-1) of FIG. 11 shows a stage in which the removal equipment before removal is instructed. Here, the equipment marked with a cross in the upper right is removed (deleted).

FIG. 11B-2 shows a stage in which the removal result after removal is displayed. Here, the equipment marked with a circle in the upper right has been removed. FIG. 11B-3 shows a case where the system diagram is switched to that before removal. Here, a state is shown in which a systematic diagram is displayed at the same position corresponding to the block diagram of (b-1) in FIG.

FIG. 11B-4 shows a case where the system diagram is switched to the system diagram after removal. Here, (b-2) of FIG.
The system diagram is displayed at the same position corresponding to the block diagram of FIG.
