  FIG. 4 shows an example of the local HI screen of the protective relay device according to the embodiment of the present invention, and FIG. 5 shows an example of the remote HI screen. In the screen example shown in FIG. 4, there are eight menus including settling, automatic inspection, test control, auxiliary setting, current operation state, abnormality content, operation content, and device overview as the main menu. On the other hand, in the example of the remote HI screen shown in FIG. 5, the test control, auxiliary settings, and the device overview are not displayed (functions cannot be executed in the remote HI). Only basic display is performed to prevent problems.

  FIG. 6 is a block diagram of the HI screen. The main menu screen includes the eight menus shown in FIG. 4, and the remote main menu screen and submenu linked to the main menu screen (except for the automatic inspection and current operation status menu). The screens and leaf screens / sub-leaf screens are associated with each other, and not only the main menu but also the detailed portion of the screen is configured in a hierarchical manner in preparation for changing the remote HI. Note that the leaf screen / sub-leaf screen is directly associated with the automatic inspection and the current operation state menu.

  FIG. 7 shows a local HI screen. As an example, a leaf screen / sub-leaf screen for main menu setting is shown. In this screen example, input means such as a numeric keypad for setting are displayed together with the setting range, tap, magnification and the like of the PCM current differential protection relay device.

  The settling is performed based on the flowchart of the settling operation shown in FIG. First, after the settling start touch switch provided in the input means is turned on, a relay element such as an 87S tap or 87S magnification is selected, the current value and ratio of the relay are set using the numeric keypad, and the write switch is turned on. The procedure of selecting and writing the relay element is repeated until the setting of the entire relay element is completed. When the setting is completed, the settling operation start switch is turned on.

  The screen data set in FIG. 8 is transmitted to the remote side, and the settling result is displayed as a remote HI screen as shown in FIG. In the example of FIG. 9, the input means displayed on the right side of FIG. 7 is deleted, and the setting value cannot be changed on the remote side.

  The HI screen as described above is created by a dedicated homepage creation software (drawing tool), and the screen configuration has a hierarchical structure and the number of screens is wide and the number of screens is large. 5 and the comparison between FIGS. 7 and 9, the display unit (screen) other than for the remote HI can be created at the same time because the local HI and the remote HI are exactly the same, but on the remote HI side, however, Each user's specific specifications are incorporated.

On the other hand, the screen display may be changed for reasons such as a problem or improvement during a test at the time of new model development, and a change in the HI display by a user instruction.
Even in such a case, it is necessary to take measures such as creating software, reducing the number of test steps, and preventing forgetting to incorporate specifications specific to the user on the remote HI side.

In order to respond to such a request, the present invention automatically creates a remote HI as follows.
