HD67815 Modbus TCP slave to KNX TP converter for seamless BMS and IAS integration with 1440 bytes

Industrial Modbus TCP slave to KNX TP converter, housing type B (wide), DIN rail mount.

HD67815 allows to connect Modbus TCP masters (such as SCADA systems, PCs or PLC controllers) with a KNX network, enabling direct data exchange between automation systems and building management infrastructures. The converter is easy to install on a DIN rail and simple to configure using the free SW67815 software included with the device. Its compact and robust design makes it suitable for use in both industrial automation and building automation environments. This device bridges the gap between industrial protocols and smart building infrastructures, ensuring that engineers, system integrators and facility managers can achieve efficient and stable integration without complex programming.

Configuration:

With the SW67815 configuration software installed on your PC you can:

• Define detailed parameters of the Modbus TCP line, including communication mapping and register allocation.
• Define the parameters of the KNX line, ensuring seamless integration with KNX actuators, sensors and switches.
• Create and manage data mapping tables between KNX objects and Modbus TCP registers.
• Enable secure bi-directional communication to synchronize building automation data with industrial networks.
• Update the device firmware to benefit from long-term support and software improvements.

This intuitive configuration process allows system integrators to shorten commissioning time and guarantee compatibility with a wide range of KNX devices, from lighting and HVAC controllers to energy meters and advanced building management modules.

Characteristics:

• Supports up to 1440 bytes in reading and 1440 bytes in writing for efficient data transfer.
• Triple isolation between KNX - Power Supply, KNX – Ethernet, and Power Supply - Ethernet for high reliability and protection against disturbances.
