Search for system screens with equipment. When the system screen is retrieved, screen information table acquisition processing 155 is performed from the screen information table 47, and in-system screen display processing is performed at step 154. In step 156, it is determined whether the equipment whose state has changed can be controlled by the own system. If the equipment can be controlled by the own system, the process proceeds to step 160. If control by the own system is not possible, external system operation information is acquired at step 158, an external system operation screen is displayed at step 159, and the process proceeds to step 160. In step 160, it is determined whether the support screen is being displayed. If it is being displayed, the process is terminated. If not, the support information is acquired in step 161, and the support screen is displayed in step 162. The process ends.
[0051]
Since the processing is performed in this way, as shown in FIG. 14, when the symbol 1 on the screen of the display device is touch-selected, the equipment information corresponding to the symbol 1 in the screen information table 47 is recognized as the device NO1, The support information corresponding to the device NO1 in the facility device information table 48 is recognized as A1, B1, and B3. As a result, the non-system operation information table 49 and the support information table are displayed as the support information Web service screen.
The Web screens of A1, B1, and B3 are displayed using the support destination transmission information of A1, B1, and B3 recorded in 50, respectively.
[0052]
In the example shown in FIG. 15, since symbol 7 is a diesel generator, the equipment to be monitored and operated and the Web server 2 are not directly operable and connected via the diesel generator control device 14. Manual intervention is required. When the symbol 7 shown in FIG. 15 is selected, the equipment information corresponding to the symbol 7 in the screen information table 47 is recognized as equipment NO7, and the operation information outside the system is recognized as A4 from the equipment NO7 in the equipment information table 48. The support information recognizes A4 and B5. As a result, the A4 operation destination transmission information recorded in the non-system operation information table 49 is used as the Web service screen for non-system operation information, and is recorded in the support information table 50 as the Web service screen for support information. The Web screen is displayed using the operation destination transmission information of A4 and B5.
[0053]
Thus, according to the present embodiment, it is possible to perform monitoring by an ITV camera other than the own system. In addition, even when an ITV camera is added or when a new equipment is newly added, monitoring outside the own system can be performed by referring to the outside-system operation information table 49 and the support information table 50. In addition, since an appropriate ITV camera in the positional relationship with the facility to be operated is set, it is possible to reduce the time and effort for searching.
[0054]
Further, by connecting the systems with a network using Web service technology and linking the Web service technologies in combination, the operator can perform information transmission suitable for the monitoring operation of the production facility and the manufacturing apparatus.
[0055]
In the above, a case where a plurality of Web servers 2 are installed in one plant has been described as shown in FIG. 1, but a plant in which a plurality of Web servers are installed may be connected by a plurality of networks.
[0056]
FIG. 16 shows an example in which the operator displays a Web information list for searching for Web services in order to support the display of the Web screen related to the selected symbol. In the example illustrated in FIG. 12, when any one of symbols 1 to 7 on the screen [T1] is touch-selected, an operation screen for the outside system operation list and the support information list is displayed in a pop-up manner.

When the operator touches and selects the A4: DG operation panel on the list-displayed operation information list screen outside the system, the Web service screen of the A4: DG operation panel is displayed. FIG. 17 shows an example in which a support information list is touch-selected from among the operation screens of the non-system operation list and the support information list displayed in a pop-up. For example, B2: ITV change-2 is touch-selected from the list screen to display the B2: ITV change-2 ITV camera screen.
[0057]
Next, an example in which an abnormal state occurs when the device NO1 changes from the on state to the off state will be described with reference to FIG. When the device NO1 is in the on state, it is displayed on the screen [T1] with a solid rectangle indicating the “on” state. Due to the change from the “ON” state to the “CUT” state, the display is changed to a hollow square display and blinks to notify the operator that an abnormal state has occurred.
[0058]
FIG. 18 shows that the device NO1 changes from the on state to the off state, and the display device notifies the operator of the abnormal state. On the screen [T1], the symbol 1 representing the device NO1 was initially represented by a solid rectangle representing the “entered” state. It can be represented by a square and blinked to inform the operator of the change. It also sounds an alarm. The screen [S1] monitoring history is displayed by the change in the state of the device NO1, and the fact that the device NO1 has changed from “ON” to “OFF” is displayed. Further, as described above, since the device NO1 recognizes the support information A1, B1, and B3, the support information A1, B1, and B3 are displayed.
[0059]
In this way, monitoring can be performed by the ITV camera at the timing when the abnormality of the facility or equipment occurs.
