Communication and configuration
In SW67814, configure Modbus TCP network parameters, the KNX device address and telegram reception and transmission. Map Modbus registers to KNX group addresses and define the meaning of the transferred data.
Connected devices must operate as Modbus TCP Server units. Configure register addresses, Modbus functions, data types and byte order using their documentation. The converter uses a TP bus on the KNX side. Prepare group addresses, data types and the required transfer direction; check the power supply for both the KNX bus and the converter.
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. Connected devices must operate as Modbus TCP Server units. Configure register addresses, Modbus functions, data types and byte order using their documentation. The converter uses a TP bus on the KNX side. Prepare group addresses, data types and the required transfer direction; check the power supply for both the KNX bus and the converter.
How is this converter configured?
In SW67814, configure Modbus TCP network parameters, the KNX device address and telegram reception and transmission. Map Modbus registers to KNX group addresses and define the meaning of the transferred data.
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.
