Page 4: Function Of The Pn/Mqtt Coupler
3 Function of the PN/MQTT Coupler The MQTT protocol has become established in recent years as a simple transmission protocol for messages in the IoT world. MQTT stands for "Message Queue Telemetry Transport Protocol" and is an OASIS standard. Information on the MQTT protocol can be found here: mqtt.org The MQTT protocol always uses a central broker for communication between devices, which receives messages from e.g. -

Broker). In the cloud, IoT systems such as HiveMQ, Amazon IoT, Microsoft Azure or Siemens Mind-sphere (in preparation) can be connected directly. White papers on the specific configuration settings can be requested from Helmholz Support. 4 Connection 4.1 Power supply The PN/MQTT coupler must be supplied with DC 24 V at the wide-range input DC 18 ... -

6 Configuration in TIA Portal Add the PN/MQTT coupler to the project and connect the coupler to the PROFINET network. Assign a device name and check the Ethernet address for the device. 6.1 Parameterization of the PN/MQTT coupler The parameterization of the PN/MQTT coupler is performed via the PROFINET hardware configurator (e.g. -

Static IP address: If the address mode is set to "Static IP", the static IP address of the X2 network can be specified here. Static IP subnet mask: If the address mode has been set to "Static IP", the subnet mask of the X2 network can be specified here. - Page 9 The value of the input modules is initialized with 0 after restarting the coupler and is permanently taken over into the input area when a new value is received via MQTT. A bit additionally indicates the reception of a value in the PLC. For each module, the Topic name must be defined unambiguously in the module parameters.

If the PN/MQTT coupler has received the correct PROFINET name, it is recognized and configured by the PLC. If the configuration is correct, the PROFINET "BF" LED should be off. To set the PROFINET name, the Helmholz IPSet Tool can also be used, which can be downloaded free of charge from the Helmholz website. -

7 Configuration of MQTT connection 7.1 Access to the web page As soon as the PN/MQTT coupler has been configured via the PROFINET PLC, the web page of the device is accessible via the PROFINET network. If the IP address is also available on the MQTT network page (static IP, DHCP successful), the web page is also accessible via the MQTT network. -
Page 12: Mqtt Configuration
7.2 MQTT Configuration The configuration to connect the MQTT broker can be done in the "MQTT" menu. In the "IP Address" section, the IP address of the right network port "X2" of the PN/MQTT Coupler is displayed and can be set if it has not been specified via the PROFINET configuration. -
Page 13: Modul-Status
MQTT payload data format: The value of a topic is always sent in simple text form. -12345 Example: Some MQTT applications expect a structured form in JSON format. Example: "value": "-12345" Publish interval: An MQTT message is sent automatically when the output value in the PLC changes. If PLC values are sent that change very fast it is possible to limit the send interval. -
