The patent application (Publication Number: US20240039820A1) describes a method for configuring a remote terminal unit (RTU) device in a Supervisory Control and Data Acquisition (SCADA) system. The method involves establishing communication between the RTU device and the SCADA server via a broker server using the Message Queuing Telemetry Transport (MQTT) messaging protocol. The RTU device sends an initial message payload to the SCADA server, which includes metric names, initial data, and parameter information. The SCADA server processes this payload and sends a subsequent message payload back to the RTU device with modified values for configuring the parameters. This method allows for efficient configuration of RTU devices in industrial applications such as oil and gas, water distribution, and renewable energy monitoring.
Furthermore, the patent application also includes a system comprising an RTU device, a SCADA system with a SCADA server, and a broker server communicating via MQTT protocol. The RTU device generates an initial message payload compliant with the Sparkplug specification, which includes metric names and version identifiers. The SCADA server processes this payload and responds based on the version information provided by the RTU device. The system allows for synchronization of parameters between primary and secondary RTU devices and is suitable for various industrial monitoring applications. Additionally, the RTU device can publish configuration version information to detect changes made locally, enhancing the overall monitoring and control capabilities of the SCADA system.
