Abstract

A display apparatus includes a display unit configured to display, about an external apparatus set as a control target by a controller, apparatus information concerning an operation state on a screen, a display-setting-information displaying unit configured to cause the display unit to display, on the screen, display setting information specified by retrieval in a display-setting-information retrieving unit, a device-value requesting unit configured to request the controller to transmit a device value retained by a device, which is an area in a memory that stores the apparatus information in the controller, a device-value receiving unit configured to receive the device value transmitted by the controller in response to the request by the device-value requesting unit, and a device-value displaying unit configured to cause the device value received by the device-value receiving unit to be displayed on the screen.

Claims

1. A display apparatus comprising:

a display unit configured to display, about an external apparatus set as a control target by a controller, apparatus information concerning an operation state on a screen;

a storing unit configured to store display setting information set for the display of the apparatus information on the display unit;

a display-mode switching unit configured to switch the screen to a normal display mode for displaying the apparatus information and a display setting information display mode for displaying the display setting information;

a display-setting-information retrieving unit configured to retrieve the display setting information from the storing unit;

a display-setting-information displaying unit configured to cause the display setting information specified by the retrieval in the display-setting-information retrieving unit to be displayed on the screen, in the display setting information display mode;

a device-value requesting unit configured to request the controller to transmit a device value retained by a device, which is an area in a memory that stores the apparatus information in the controller;

a device-value receiving unit configured to receive the device value transmitted by the controller in response to the request by the device-value requesting unit; and

a device-value displaying unit configured to cause the device value received by the device-value receiving unit to be displayed on the screen, wherein

the device-value requesting unit receives input operation performed according to content of the display setting information displayed by the display-setting-information displaying unit and requests transmission of the device value.

2. The display apparatus according to claim 1, further comprising a format database configured to store format data in which a plurality of formats for defining display forms of the device value on the screen, a device type representing whether the device value is a bit or a word, and a device code affixed to the device are associated with one another, wherein

the device-value displaying unit can sequentially change a format of the device value received by the device-value receiving unit among the formats included in the format data retrieved from the format database.

3. The display apparatus according to claim 1, further comprising a processed-value displaying unit configured to calculate the device value according to a processing method included in the display setting information specified by the retrieval in the display-setting-information retrieving unit and cause the display unit to display the device value as a processed value.

4. The display apparatus according to claim 1, further comprising:

a device character string database configured to store device character string data for converting a device code affixed to the device into a character string; and

a device-character-string displaying unit configured to display, using a device code included in the display setting information specified by the retrieval in the display-setting-information retrieving unit, a character string retrieved from the device character string database.

5. The display apparatus according to claim 1, further comprising a device-value-change-content displaying unit configured to cause, about a change of the device value specified from the display setting information, designated change content to be displayed on the screen.

6. An operation checking method for a display apparatus including a display unit configured to display, about an external apparatus set as a control target by a controller, apparatus information concerning an operation state on a screen, the operation checking method comprising:

a display-mode switching step for switching the screen to a normal display mode for displaying the apparatus information and a display setting information display mode for displaying display setting information set for the display of the apparatus information on the display unit;

a display-setting-information retrieving step for retrieving the display setting information stored in advance in a storing unit included in the display apparatus;

a display-setting-information displaying step for causing the display setting information specified by the retrieval in the display-setting-information retrieving step to be displayed on the screen in the display setting information display mode;

a device-value requesting step for requesting the controller to transmit a device value retained by a device, which is an area in a memory that stores the apparatus information in the controller;

a device-value receiving step for receiving the device value transmitted by the controller in response to the request in the device-value requesting step; and

a device-value displaying step for causing the device value received in the device-value receiving step on the screen, wherein

in the device-value requesting step, on reception of an input operation performed according to the display information displayed in the display-setting-information displaying step, transmission of the device value is requested.

7. The operation checking method for the display apparatus according to claim 6, wherein

format data in which a plurality of formats for defining display forms of the device value on the screen, a device type representing whether the device value is a bit or a word, and a device code affixed to the device are associated with one another is stored in a format database, and

in the device-value displaying step, a format of the device value received in the device-value receiving step can be sequentially changed among the formats included in the format data retrieved from the format database.

8. The operation checking method for the display apparatus according to claim 6, further comprising a processed-value displaying step for calculating the device value according to a processing method included in the display setting information specified in the display-setting-information retrieving step and causing the display unit to display the device value as a processed value.

9. The operation checking method for the display apparatus according to claim 6, wherein

device character string data for converting a device code affixed to the device into a character string is stored in a device character string database, and

the operation checking method further comprising a device-character-string displaying step for displaying, using a device code included in the display setting information specified in the display-setting-information retrieving step, a character string retrieved from the device character string database.

10. The operation checking method for the display apparatus according to claim 6, further comprising a device-value-change-content displaying step for displaying change content designated when a device value included in the display setting information specified in the display-setting-information retrieving step is changed.
