Communication and configuration
In SW67844, configure Modbus TCP network settings, connected DALI nodes and register mapping. Use DALI Console to prepare addresses, groups and scenes and test communication with luminaires.
The peer must operate as a Modbus TCP Server. Prepare register addresses, data types, byte order and the required read/write polling cycle. The base code HD67844-B2 does not specify DALI bus power. Before ordering, we will select HD67844-B2-Y with DALI bus power or HD67844-B2-N without it to match the installation. We will also check support for the functions of the specific luminaires and their control gear.
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 peer must operate as a Modbus TCP Server. Prepare register addresses, data types, byte order and the required read/write polling cycle. The base code HD67844-B2 does not specify DALI bus power. Before ordering, we will select HD67844-B2-Y with DALI bus power or HD67844-B2-N without it to match the installation. We will also check support for the functions of the specific luminaires and their control gear.
How is this converter configured?
In SW67844, configure Modbus TCP network settings, connected DALI nodes and register mapping. Use DALI Console to prepare addresses, groups and scenes and test communication with luminaires.
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.
