The need to connect fieldbus networks to higher communications levels is increasing rapidly. The following applies quite clearly at Helmholz, not only for the fieldbus couplers, but also across the entire product portfolio for “industrial communication“: Usability first! With its technical realization of gateways, Helmholz ensures absolute user-friendliness, so that the type of configuration is intuitive for many customers. This familiarity provides many users with an impulse to accept the theme of modern connectivity and system networking.
With the new PN/MQTT Coupler, Helmholz expands its previous product portfolio to fieldbus gateways with another type of communication.
Here, the user can create a direct connection of the field or PLC level into the cloud. Data is transmitted securely with SSL encoding and authentication. As with all fieldbus couplers of the manufacturer Helmholz, there is also no additional external software necessary for the new PROFINET/MQTT Coupler. The very compact design of the Helmholz bus coupler saves space and thus also enables retroactive installation into existing systems.

With the PN/MQTT Coupler, the direct transmission of data between a PROFINET machine (PLC) and a MQTT broker is possible. Values can be sent from the PLC (“Publish”), as well as values received by an MQTT broker via PROFINET (“Subscribe”). The PN/MQTT Coupler can connect brokers both locally in the own network (“On premise”) as well as via the Internet in the cloud.
Thanks to the direct integration into the PLC, full control of the data exchange with the IoT world remains in the hand of the machine manufacturer!
