Data transfer
MQTT data transfer becomes more suitable for industry
With the support of MQTT Sparkplug B in ibaPDA, users can now send all captured process and sensor data in Sparkplug B formatted data to an MQTT broker from version 8.3.
MQTT (Message Queuing Telemetry Transport) is a message protocol that uses a publisher / subscriber architecture and is operated via a central broker. Data sources publish their data via a publish command to a data broker, subscribers retrieve the data independently. In this way, the network bandwidth can be conserved and the resource requirements of the participating devices can be reduced.
However, the standardisation of data exchange in MQTT has not been possible so far. This goal is pursued by the Sparkplug B extension: this ensures that developers have clear guidelines for the design of the topic namespace, how the payload data is to be structured and how the client status is to be held and communicated. In addition, since with MQTT and Sparkplug B data transmission only occurs when data changes, message sizes and transmission frequency are minimised. This results in a better and, above all, more robust connection between the participants, which improves the industrial suitability of the communication with the measurement data acquisition system ibaPDA.
