FIG. 6 is a flow chart showing the procedure of transfer processing by the transfer unit 14 shown in FIG. The procedures of steps S21 to S23 shown in FIG. 6 are included in the transfer process of step S15 shown in FIG.

In step S21, the transfer unit 14 acquires information indicating the current state of the programmable display 20 by communication with the programmable display 20 through the communication I / F 15. From the information, in step S22, the transfer unit 14 determines whether the programmable display 20 is currently in a state where the screen data 17 can be received.

Immediately after the screen data 17 is transferred, when the information indicating that the programmable display 20 is restarting is obtained in step S21, the transfer unit 14 receives the screen data 17 by the programmable display 20. It is determined that the state is not possible (step S22, No). The transfer unit 14 repeats steps S21 and S22 until the programmable display 20 can receive the screen data 17.

On the other hand, when the information indicating that the operation state is normal is obtained in step S21, the transfer unit 14 determines that the programmable display 20 can receive the screen data 17 (step S22, Yes). . Based on the information acquired from programmable display 20 at step S 21, transfer unit 14 confirms that programmable display 20 is ready to receive screen data 17, and then transmits the information to programmable display 20. The screen data 17 is transferred.

In step S23, the transfer unit 14 transfers the screen data 17 to the programmable display 20. Specifically, the communication I / F 15 transmits a copy of the screen data 17 held in the storage unit 18 to the programmable display 20 according to the instruction of the transfer unit 14. The storage unit 18 keeps holding the screen data 17. Thus, the transfer unit 14 ends the transfer process. The drawing device 10 automatically transfers the screen data 17 to the programmable display 20 by the processing of the transfer unit 14 in FIGS. 5 and 6 regardless of the operation of the user. The transfer unit 14 can transfer the screen data 17 utilizing a period in which the screen data 17 can be transferred by itself and the programmable display 20 can receive the screen data 17.

When the programmable display 20 receives the screen data from the drawing device 10, the programmable display 20 rewrites the display and operation screen data 26 held in the storage unit 25 into the received screen data. The programmable display 20 performs display and operation using the rewritten screen data 26.

The drawing device 10 holds screen data 17 used for transfer separately from the screen data 16 used for editing. When the drawing device 10 detects that the screen data 16 for editing and the screen data 17 for transfer are different, the screen data 17 for transfer is updated to the same data as the screen data 16 for editing. In parallel with the editing of the screen data 16 by the editing unit 13, the drawing device 10 can transfer the screen data 17 by the transfer unit 14 regardless of the user's operation. While the screen data 17 is being transferred, the user can continue editing the screen data 16 without interruption.

FIG. 7 is a diagram for explaining the operation procedure of the drawing device 10 and the programmable display 20 shown in FIG. At the start of the operation procedure shown in FIG. 7, it is assumed that the storage unit 18 of the drawing device 10 holds data d0 which is the screen data 16 for editing. Further, the storage unit 25 of the programmable display 20 holds data d0 which is screen data 26 for display and operation.

The editing unit 13 executes editing processing of the data d0 in a period T1 in accordance with the input operation to the user I / F 12. When the data d1 subjected to the editing process is determined from the data d0, the editing unit 13 rewrites the data d0 which is the screen data 16 held in the storage unit 18 into the data d1. When the editing unit 13 changes the editing screen data 16 stored in the storage unit 18 from the data d0 to the data d1, the editing processing of the data d1 in the period T2 can be continued immediately thereafter.

In step S41-1, the transfer unit 14 collates the screen data 16 for editing with the screen data 17 for transfer, and updates the screen data 17 for transfer from the data d0 to the data d1. In step S42-1, the transfer unit 14 transfers the data d1, which is the updated screen data 17, to the programmable display 20 in the period t1. As described above, while the editing unit 13 continues the editing process, the transfer unit 14 can execute collation of the

screen data

16 and 17, update of the screen data 17, and transfer of the screen data 17. . The editing unit 13 can change the screen data 16 for editing while the transfer unit 14 is executing the transfer process.

The programmable display 20 receives the data d1 transferred from the drawing device 10, and rewrites the display and operation screen data 26 from the data d0 to the data d1. Since the editing unit 13 can execute the editing process on the data d1 overlapping with the period t1 in which the transfer unit 14 transfers the data d1, the drawing device 10 waits for the period t1 to elapse before the data d1. The time required for debugging the screen data 16 can be shortened as compared with the case where the editing process is started.

When the data d2 on which the editing process has been performed is determined from the data d1, the editing unit 13 changes the screen data 16 for editing from the data d1 to the data d2. The editing unit 13 continues the editing process of the data d2 in the period T3. In step S41-2, the transfer unit 14 collates the screen data 16 for editing with the screen data 17 for transfer, and updates the screen data 17 for transfer from the data d1 to the data d2. In step S42-2, the transfer unit 14 transfers the data d2, which is the updated screen data 17, to the programmable display 20 in the period t2. The transfer unit 14 performs the matching and updating in step S41-3 and the transfer in the period t3 in step S42-3, as in the case of the data d1 and d2, for the data d3 for which the editing process has been performed from the data d2 Do.

In the example shown in FIG. 7, if the next screen data 16 is to be edited after waiting for the transfer of the screen data 16 by the user's manual operation, the drawing device 10 performs the editing process in the periods T1, T2 and T3 and The transfer processing in the periods t1, t2 and t3 is alternately performed. A period required for debugging from data d0 to data d3 is a period obtained by adding periods T1, T2 and T3 and periods t1, t2 and t3.

In the present embodiment, the drawing device 10 automatically executes the transfer process of the screen data 17 in the periods t1 and t2 in parallel with the editing process of the screen data 16 in the periods T2 and T3. The drawing device 10 can shorten the time required for debugging from the start of the period T1 to the end of the period t3 as compared with the case where the editing process and the transfer process are alternately performed. Although the transfer unit 14 can transfer the screen data 17 and the programmable display 20 can receive the screen data 17, the transfer of the drawing device 10 is awaited until the user performs a manual operation. Can avoid the situation that The drawing device 10 can efficiently debug the screen data 16 by transferring the screen data 17 in parallel with the editing process.

The drawing device 10 may switch between the case of automatically transferring the screen data 17 as shown in FIG. 7 and the case of transferring the screen data 17 by the user's manual operation. When the automatic transfer is selected, the drawing apparatus 10 performs the transfer process according to the procedure of FIGS. 5 and 6. When transfer by manual operation is selected, the drawing device 10 transfers the screen data 17 in accordance with the input operation by the user. The user can select transfer processing according to the procedure of FIGS. 5 and 6 and transfer by manual operation in accordance with the amount of data that can be communicated between the drawing device 10 and the programmable display 20.

According to the embodiment, the drawing device 10 collates the screen data 16 for editing with the screen data 17 for transfer, and when it is detected that the screen data 17 and the screen data 16 are different, the screen data By updating 17 to the same data as the screen data 16, transfer processing of the screen data 17 is executed in parallel with editing processing of the screen data 16. As a result, the drawing device 10 has the effect of being able to improve the work efficiency of debugging the screen data 16.

In the present embodiment, the storage unit is the external storage device 44. However, the storage unit may be provided inside the drawing device 10, or may be externally attached to the drawing device 10. .
