- step S202 the programmable logic controller configuration candidate display unit 36 highlights the most frequently selected programmable logic controller configuration based on the tendency of the selection state of others and the tendency of the selection state of the user. Thus, in the subsequent step S103, the user can easily select a desired programmable logic controller configuration.
- step S203 the programmable logic controller setting file output unit 40 creates a list of devices necessary for the configuration of the programmable logic controller used in the programmable logic controller setting file 50 and outputs the list to the setting processing unit 35.
- the setting processing unit 35 causes the data management unit 39 to manage data of a list of devices necessary for the programmable logic controller configuration.
- the user uses the data of the list of devices necessary for the programmable logic controller configuration managed by the data management unit 39 and uses the web communication unit 41 to configure the devices necessary for configuring the monitoring control system. You can place an order with the seller.
- a programmable logic controller, a control device, and a network necessary for a programmable logic controller configuration that generates a programmable logic controller setting file by automatically transmitting data of a list of necessary devices to a seller by e-mail. Can be ordered automatically.
- step S204 the programmable logic controller configuration candidate selection unit 37 causes the data management unit 39 to manage the selection result.
- the programmable logic controller configuration candidate display unit 36 can highlight the programmable logic controller configuration by reflecting the current selection state in the process of step S202 during the next and subsequent operations.
- the programmable logic controller setting file generation support device can acquire information from the internet or the programmable logic controller that downloaded the programmable logic controller setting file, the specification of the programmable logic controller or the control device is revised. However, it is possible to determine whether or not the programmable logic controller configuration needs to be reconstructed based on the latest specification information, and to perform the restructuring process. Moreover, the process of constructing a programmable logic controller configuration including a programmable logic controller in operation can be omitted. In addition, the programmable logic controller, the control device, and the network equipment necessary for configuring the monitoring control system can be ordered from the seller using the web communication unit 41.
- the configuration described in the above embodiment shows an example of the contents of the present invention, and can be combined with another known technique, and can be combined with other configurations without departing from the gist of the present invention.
