Communication and configuration
In SW67951, configure PROFIBUS, the broker connection and MQTT publish/subscribe topics. The software can generate a GSD file for integrating the gateway into the PROFIBUS Master project.
The HD67951-B2 does not independently control other PROFIBUS Slave units. Use the Master version HD67950-B2 for that application. Check MQTT security and connection parameters against the broker and firmware.
Supply and accessories
Please provide the complete order code. If you need a power supply, connection cables or help with configuration, include them in your enquiry. We will confirm the scope of supply and required accessories for your installation in the quotation.
Documentation and software
Diagrams and hardware version


The images help identify the hardware version. When replacing an older unit, compare its label, connectors and dimensions; we will confirm the version to be supplied in the quotation.
Frequently asked questions
Is knowing the two protocols enough?
The device roles, physical interfaces and data to be transferred must also be checked. The HD67951-B2 does not independently control other PROFIBUS Slave units. Use the Master version HD67950-B2 for that application. Check MQTT security and connection parameters against the broker and firmware.
How is this converter configured?
In SW67951, configure PROFIBUS, the broker connection and MQTT publish/subscribe topics. The software can generate a GSD file for integrating the gateway into the PROFIBUS Master project.
What information should I send to check the selection?
Send the exact device models at both ends, the protocols and communication roles, the number of devices and the required values. For a PLC, include the firmware and method of accessing its data.
