Zusammenfassung:Abstract The present invention relates to an implementation layer of the Message Queuing Telemetry Transport (MQTT) messaging protocol, such as the Sparkplug B specification, to define a payload to add configuration properties for an RTU device. These properties can relate to metrics (measurement points known as metrics, points, tags, or registers) in the RTU device via a set of custom properties, or related to the RTU device's functionality by deriving metrics and properties specifically to set other behaviour such as for communications, data management, metering, etc. In addition, aspects of the present disclosure permit the RTU device to present custom metrics to publish configuration version information, allowing the SCADA server to detect changes made locally. A method of configuring an RTU device of a SCADA system is also disclosed and comprises establishing communication between the RTU device and a SCADA server of the SCADA system via a broker server.
