  • Patent number: 11665223
    Abstract: Controller devices may be configured to execute a network discovery service to identify other devices on a network, including other controller devices, user computing devices, and/or human machine interface devices. The controller devices may communicate with the devices on the network. An individual controller device may, upon connection to a human machine interface device, provide to the human machine interface device via a web server, a graphical user interface from which a user may configure the controller device or connect to another controller device on the network.

  • Patent number: 11558449
    Abstract: Controller devices may be configured to automatically connect to a remote management server (e.g., a “cloud”-based management server), and may offload received data and analyses to the remote management server via wired or wireless communications. The controller devices may further communicate with the management server, user computing devices, and/or human machine interface devices, e.g., to provide remote access to the controller device, provide real-time information from the controller device, receive configurations/updates, provide interactive graphical user interfaces, and/or the like.
