MQTT (Message Queuing Telemetry Transport) is an ISO standard publish-subscribe based messaging protocol.
It works on top of the TCP/IP protocol and is designed for connections with remote locations where a "small code footprint" is required or the network bandwidth is limited.
The MQTT driver by INNOVIS SOLUTIONS allows your WinCC OA application to communicate with several brokers simultaneously, turning your plant fit to play in IoT and Industry 4.0.
It supports both plain text and JSON formatted messages. High availability is achieved through the definition of fallback servers and support of WinCC OA redundancy.
Easy to install and with a rugged design, it is delivered with an extensive online documentation which guides you step by step at launching your project.
