Abstract

A display apparatus (101) includes an input unit (220); a communication unit (250); a display unit (210); and a control unit (240) including a display content setting unit (244), a layout setting unit (245) for setting a screen layout, and a screen generation unit (246) for generating a display screen based on the display content, the screen layout, and information acquired via the communication unit (250) and concerning the PLC. The display content setting unit (244) displays a candidate list of a display item based on at least one of: network configuration information (231) of equipments (103) and a PLC (102) which is created in advance, an equipment information file (232), and device allocation information (233) of the equipments (103) and the PLC (102), to the display unit, and sets display content based on input information coming from the input unit (220). The display apparatus can thus generate a display screen for an FA system based on information shared with another apparatus, as information concerning an equipment which is information other than screen configuration information.

First claim

The invention claimed is:

7. A factory automation system comprising:
the display screen generation apparatus according to claim 6 ;
a display to display the display screen generated by the display screen generation apparatus;
a plurality of equipment; and
a PLC to which the plurality of equipment are connected.

8. A factory automation system comprising:
the display screen generation apparatus according to claim 1 ;
a display to display the display screen generated by the display screen generation apparatus;
a plurality of equipment; and
a PLC to which the plurality of equipment are connected.

9. A display screen generation method of generating a display screen in a display apparatus connected to a programmable logic controller (PLC) to which a plurality of equipment are connected, the display screen generation method comprising:
an information acquisition step of acquiring an equipment information file and device allocation information, the equipment information file concerning the plurality of equipment and being created in advance by another device, the device allocation information concerning a device allocation of the plurality of equipment and the PLC and being created in advance by still another device that is different from the device having created the equipment information file; and
performing an automated display screen generation process, the automated display screen generation process including
extracting network information including the acquired network configuration information and displaying the extracted information as target network candidate list;
setting, in response to user selection of a target network candidate, a network configuration for a display screen to be generated;
displaying a list of candidate screen frames, each candidate screen frame corresponding to a different screen type, selected from an input/output type, an operation type, and a command type;
setting, in response to user selection of a candidate screen frame, a screen type, for the display screen to be generated;
displaying, in accordance with the set screen type, a display content setting screen which displays a candidate list of display items based on the acquired equipment information file and tagged with allocation information acquired from the acquired device allocation information, where the candidate display items include candidate equipment which the user can select whether to include in the generated display screen;
setting, in response to user selection of one or more selected candidate display items, display content for the display screen to be generated;
displaying, a layout setting screen including a candidate list of screen layouts corresponding to the set display items associated with the set display content;
