Abstract: An information providing method includes (i) starting, by a control device, a communication session with a server in response to establishment of a communication connection with a terminal, and (ii) issuing, by the server, temporary access information for accessing a service in a manner that depends on the communication session. The access information is different for each communication session. The information providing method further includes (iii) notifying, by the control device, the access information to the terminal, and (iv) providing, by the server, target information collected from the control device to the terminal in response to access from the terminal based on the access information. Accordingly, the threat to security when providing information of the control device is reduced.

Abstract: The control system is equipped with a generator that generates a container inclusive of an image of runtime including a user program that defines computations for control of a control object and an execution environment of the user program; and an orchestrator that releases the container to one or both of the control device and the server. The control device and the server each have a container engine for container deployment and each deploy the container released by the orchestrator to generate an instance of the runtime image and perform the computations for control.

Abstract: The PLC is provided that outputs assistance information for assisting elimination of a target abnormality by using abnormality history data having written thereto an abnormality log element containing type information, occurrence time, and elimination time of an abnormality and operation history data having written thereto an operation log element containing content information and execution time of an operation. The output unit extracts, from the abnormality history data, an abnormality log element containing the type information showing a type identical to a type of the target abnormality. The output unit extracts, from the operation history data, an operation log element containing the execution time falling within a period from the occurrence time to the elimination time contained in the abnormality log element thus extracted, and generates the assistance information based on the extracted operation log element.

Abstract: The objective of the present invention is to diversify the types of OS compatible with constituent elements of an HMI program. A support device receives a specification of UI elements of program code compatible with a first OS type, said UI elements constituting an HMI program executed by control devices which are targets of factory automation (FA); generates program code of UI elements compatible with a second OS type from the specified UI elements; and generates a wrapper program, which includes the program code compatible with the second OS type and an instruction code instructing to generate an execution module that includes the relevant program code, when a condition that the OS possessed by the target device is not the first OS type is satisfied. A program in executable code is generated from the HMI program having the wrapper program incorporated therein.

Abstract: The support device acquires locus information in which a position of a machine tool corresponding to an instruction value generated by execution of an NC program is associated with time information indicating a control time using the instruction value, and variable history information in which a value of a variable updated by execution of the sequence program is associated with time information indicating an update time The support device selects a target period in an execution period of a program, displays a portion corresponding to the target period in transition indicated by the locus information on a display device, and displays the value of the variable in the target period on the display device based on the variable history information.

Abstract: For each of one or a plurality of control units, a development support device registers a service corresponding to the control unit and a screen generation code generating a UI screen corresponding to the service in a server. The server includes a service module providing a target service of a target control unit requested by the terminal. The service module accesses the target control unit to collect target data obtained by the target control unit executing the control program; and provides a UI screen, which is indicated by the screen generation code corresponding to the target service and includes the target data, to the terminal. Thus, the one or the plurality of control units can be easily monitored.

Abstract: The objective of the present invention is to simplify the transfer of a program that has been edited. A support device, which assists in the development of a program executed by a target device provided in factory automation (FA), carries out a transfer process for transferring the program to the target device. The program includes a control program for controlling a machine and an HMI program for processing a variable used by the control program. When the control program or the HMI program has been edited, the support device simultaneously transfers the control program and the HMI program respectively to a control device and an HMI device.
