MQTT stands for &#8220;Message Queue Telemetry Transport Protocol&#8221; and is an OASIS standard. The MQTT protocol always uses a central broker for communication between devices, which receives messages from, for example, a sensor and forwards them to interested devices, such as a control unit. When a sensor sends data to the broker, it is called a &#8220;publish&#8221;. If a device needs data, it must subscribe to the broker (&#8220;Subscribe&#8221;). The broker delivers the data to all subscribers when new data has arrived from the publisher.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone wp-image-6745\" src=\"https:\/\/omina.com.vn\/wp-content\/uploads\/sites\/2\/2022\/07\/PN-MQTT-coupler-body-1.png\" alt=\"\" width=\"900\" height=\"463\" srcset=\"https:\/\/omina.com.vn\/wp-content\/uploads\/sites\/2\/2022\/07\/PN-MQTT-coupler-body-1.png 985w, https:\/\/omina.com.vn\/wp-content\/uploads\/sites\/2\/2022\/07\/PN-MQTT-coupler-body-1-300x154.png 300w, https:\/\/omina.com.vn\/wp-content\/uploads\/sites\/2\/2022\/07\/PN-MQTT-coupler-body-1-768x395.png 768w, https:\/\/omina.com.vn\/wp-content\/uploads\/sites\/2\/2022\/07\/PN-MQTT-coupler-body-1-150x77.png 150w\" sizes=\"auto, (max-width: 900px) 100vw, 900px\" \/><br \/>\nWith the PN\/MQTT Coupler it is possible to transfer values between a PROFINET machine (PLC) and a MQTT broker.
