  S23. In the case of No in S21, the command reception lock is released.

  S24. Notify the original priority client of permission.

  By following the above procedure, check the authentication for the interrupt password input that has been set in advance, notify the server of the status change information from the client that obtained the authentication permission, and the server sends the status change information that permits the interrupt to the interrupt client Is possible.

  FIG. 11 is a work authority switching control flowchart among a plurality of clients according to an embodiment of the present invention. Hereinafter, the operation flow of FIG. 11 will be described with reference to FIG.

S25. When the operator operates the clients 2 ₁ and 2 ₂ , the server 1 is automatically started.

  S26. Schedule information is acquired from the management database 14.

  S27. Counter n = 0 is set.

  S28. It is determined whether or not the client n is currently permitted to operate.

  S29. If Yes in S28, command information executed by another client is acquired from the command history database 19.

  S30. The client n is notified of a message indicating that it is currently permitted and command history information.

  S31. In the case of No in S28, a message indicating that it is currently not permitted is notified to the client n.

  S32. Determine whether all clients have completed their work.

  S33. In the case of No in S32, the client with client number +1 is selected and fed back to the step of S28.

  According to the above procedure, when the schedule information of the client operation authority set in advance gives the operation authority to another client according to the time, the new work record information operated by the client having the operation authority before, a new client Can be sent to other monitors.
