Abstract: An information processing apparatus includes: a display unit displaying a generation screen of a UI; a storage unit storing object images serving as candidates for configuring the UI; an operation receiving unit receiving a selection of arbitrary object images among the object images and receiving an operation for arranging the selected object images at arbitrary positions on the generation screen; and a build unit outputting an execution file configuring a UI including the object images arranged on the generation screen based on reception of a build instruction for the UI. When the build instruction is received in a state in which two or more object images are arranged on the generation screen the build unit generates a composite image including the two or more object images and further outputs coordinate information of each of the object images serving as composition sources inside the composite image and the composite image.

Abstract: The disclosure provides a control device including a memory storing address information and a server section communicating with the external machine serving as a destination of publishing the address information. The server section includes a determining section, a monitoring section, and an address managing section. The determining section determines priority levels of publishing variables included in a control program to the external machine in accordance with a predetermined rule. The monitoring section monitors free capacity of the memory. With respect to public variables for the external machine among the variables included in the control program, the address managing section adds logical addresses of the respective public variables to the address information in order of the publishing priority levels as long as the free capacity does not fall below a predetermined threshold.

Abstract: In the disclosure, HMI data is mirrored under high robustness. An IPC operates in an OS and a real time OS. The IPC includes a first data managing part that sequentially performs acquisition processing of the HMI data by an HMI application of the OS, a buffer memorizing the HMI data by the first data managing part, a second data managing part that exchanges data with the first data managing part by a mirroring processing part of the real time OS, and a mirroring data holding part memorizing data by the second data managing part. The data managing part memorizes the HMI data in the buffer for each acquisition of the HMI data and transmits the HMI data to the second data managing part as mirroring data, the data managing part memorizes the mirroring data in the mirroring data holding part for each reception of the minoring data.

Abstract: One aspect of the present invention provides a programmable indicator, which can present information on a failure to the user with little delay when failing to periodically acquire data from a PLC. The programmable indicator includes a display screen, a communicator configured to communicate with the PLC, and a controller configured to control the display screen and the communicator. The controller acquires data from the PLC through the communicator in a predetermined period. When failing to acquire the data, the controller displays a name identifying the data and successful timing on the display screen, the successful timing being associated with successful acquisition of the latest data before the failure.
