MQTT is a lightweight publish/subscribe message protocol. MQTT is popular with IOT (Internet of things) applications where bandwidth may be low or unreliable.

Devices and sensors can use MQTT to publish messages of measurement and state data. MQTT clients such a TopView can subscribe to messages to retrieve the measurement and state data published by the devices and sensors.

TopView Alarm and Notification Software v6.32 includes support for MQTT as both a publisher and subscriber:

  • Publish: All versions of TopView (OPC/SCADA, PI, SQL, …) can publish MQTT messages
  • Subscribe: TopView for MQTT is designed to monitor MQTT messages for measurement and state data. The message content (payload) can be parsed by TopView (XML, JSON, CSV) for real-time monitoring, alarming, and notification.
