MQTT Publisher for SIMATIC CPU
https://support.industry.siemens.com/cs/document/109748872/mqtt-publisher-for-simatic-cpu
The “Message Queue Telemetry Transport” is a simple protocol on TCP/IP level. It is suitable for messaging between devices with minimum functionality and for transmission via unreliable networks. With the function block from this application example, the MQTT protocol is implemented into a SIMATIC S7-1500, SIMATIC S7-1200 and SIMATIC S7-300.
The “Message Queue Telemetry Transport” is a simply structured binary Publish/ Subscribe protocol on TCP/IP level. It is suitable for messaging between devices with minimum functionality and for transmission via unreliable networks with low bandwith and high latency. With these characteristics, MQTT plays a vital role for the IoT and in M2M communication.
The application example provides you with a function block for the SIMATIC CPU. The “LMqtt_Publisher” function block integrates the MQTT client function and allows you to transmit MQTT messages to a broker (publisher role). In this, the communication can be secured via a TLS connection. You can reach the broker with a static ip address or a qualified domain name.
The following picture shows the secure mqtt-messaging with a SIMATIC S7-1500.
