Description
Introduction
The WEINZIERL KNX Modbus TCP Gateway 716 (Art.-Nr. 5425) provides a compact, reliable interface between KNX TP and Modbus TCP protocols over IP networks. Housed in a standard 1-module (18 mm) DIN-rail enclosure, this versatile gateway is powered directly by the KNX TP bus, eliminating the need for an external power supply unit. This device is part of our KNX Gateway products range.
Supporting up to 250 freely configurable datapoints, the gateway can operate as a Modbus TCP master addressing up to 5 slave devices or function as a Modbus TCP slave. Integrated support for KNX Security ensures protected data communication, while its dual capability as a programming interface allows engineers to connect PCs directly to the KNX bus via ETS.
Key Features
- 250 freely configurable datapoints with automatic scaling and data point type conversion to KNX standards.
- Modbus TCP Master (up to 5 slave devices) or Modbus TCP Slave operation modes.
- Front-panel manual control with 2 buttons and 3 multi-colored LEDs for test functions and status diagnostics.
- Integrated ETS IP programming interface functionality for system commissioning.
- KNX Security standard support for encrypted communication.
- Compatibility with Weinzierl DCA Modbus TCP 716 Gateway Config Tool for configuration export and import.
Benefits
- Enables seamless communication between Modbus TCP devices and KNX networks with 250 freely configurable datapoints.
- Bus-powered design operates directly from the KNX TP line within a compact 1 DIN module (18 mm) housing.
- Protects network integrity with built-in KNX Security support.
- Functions as a direct KNX programming interface for connecting ETS software on PCs to the KNX bus over IP.
- Flexible system design supporting both Modbus TCP Master (up to 5 slaves) and Modbus TCP Slave modes.
- Streamlined parameter configuration entirely within ETS 5 / ETS 6 without needing external software tools.
Technical Specifications
Applications
Integration of HVAC systems such as heat pumps (Novelan, alpha innotec, iDM, Stiebel) and heating controllers (ETA wood chip systems, LEDA Werk burn-off control) into KNX building management. Explore more products from WEINZIERL for professional building automation projects.
Connecting solar PV systems and hybrid inverters (Fronius, Huawei, Hoymiles, Kaco, Kostal, Sunspec) into KNX energy automation.
