Embodiment approach 1
[0044] figure 1 It is a schematic diagram which shows an example of the schematic structure of the control system 1 concerning Embodiment 1. FIG. like figure 1 As shown, the control system 1 which concerns on Embodiment 1 has the control apparatus 100, the programmable display 200, and the programmable display 300, and the control apparatus 100, the programmable display 200, and the programmable display 300 are mutually communicable via the network 10. state connected. The network 10 may include the Internet and a Local Area Network (LAN).
[0045] The control device 100 is, for example, an FA device such as a PLC (Programable Logic Controller) that controls a plurality of devices operating on a production line.
[0046] The programmable display 200 and the programmable display 300 are provided with screen data corresponding to a plurality of screens that display information about the equipment connected to the control device 100 and receive the operation of the equipment c...
Embodiment approach 2
[0109] In Embodiment 1, when the result that the programmable display 200 and the programmable display 300 attempt to acquire the operation right in accordance with the operation right acquisition request is that the acquisition of the operation right fails, the screen that does not require the operation right may be executed. Display control. Below, use Figure 12 , the process of the programmable display which concerns on Embodiment 2 is demonstrated. Figure 12 It is a flowchart which shows an example of the screen display process by the programmable display 300 which concerns on Embodiment 2. Figure 12 The processing shown has the same Figure 10 The processing shown is basically the same processing procedure, but the processing procedure of step S409 is different.
[0110] That is, when the programmable display 300 determines whether the acquisition of the operation right has succeeded or not and the result is that the acquisition of the operation right has failed (st...
Embodiment approach 3
[0113] The operation right for operating the screen that is the subject of exclusive control may be managed individually on a system-by-system basis. Figure 13 It is a schematic diagram which shows an example of the schematic structure of the control system 2 which concerns on Embodiment 3. FIG.
[0114] like Figure 13 As shown, the control system 2 which concerns on Embodiment 3 consists of the system G1 including the programmable display 400A, the programmable display 400B, and the control apparatus 500A, and the system G2 including the programmable display 400C and the programmable display 400D. and control device 500B.
[0115] 400 A of programmable displays and 400 B of programmable displays perform the display of the information regarding the equipment connected to 500 A of control apparatuses, and the operation input regarding the operation control of this equipment. 400 C of programmable displays and 400 D of programmable displays perform the display of the informa...
