Publication number: 20230418263Abstract: An industrial integrated development environment (IDE) supports the use of graphical device profiles to configure device parameters as part of an industrial control project. To allow an edit to first device represented by a first device profile to be applied easily to other device profiles, the industrial IDE system can record a user's interactions with the first device profile during a session of editing the device's parameters. These interactions are recorded as a sequence of cursor movements, mouse-click selections, keystrokes, and other such interactions. The user interactions are stored as a reusable interaction record which can be selectively applied to other device profiles to recreate or replay the user interactions on those other profiles.Type: ApplicationFiled: June 22, 2022Publication date: December 28, 2023Inventors: Thomas Kazushige Sugimoto, Qin Cheng Jin, Wang Zhen

Publication number: 20230418568Abstract: An industrial integrated development environment (IDE) is extended to support creation of device profiles using an intuitive graphical development environment. The environment comprises a device profile development interface that allows a user to select device profile views to be included in a device profile for an industrial device, and to submit edits to the underlying code for the selected device profile views. The system can then generate a new device profile from the modified device profile code. The device profile can be registered with the industrial IDE and used to view and edit device parameters of a corresponding industrial device. The device profile development environment also supports dynamic validation of profile view edits, rendering of graphical previews of the modified device profile view, and submission of both code-based and graphical profile view edits.Type: ApplicationFiled: June 22, 2022Publication date: December 28, 2023Inventors: Thomas Kazushige Sugimoto, Qin Cheng Jin, Wang Zhen
