Weinzierl Engineering Gmbh Better

1. Overview & Identity Weinzierl Engineering GmbH is a German, mid-sized, privately held engineering and automation company. Unlike many niche automation firms, Weinzierl has built its reputation on open standards (KNX, BACnet, Modbus, MQTT, OPC UA) and hardware/software co-design – they develop both the physical controllers and the programming environment (ETS add-ons, MAINS, 845 iServices).

Headquarters: Töging am Inn, Bavaria, Germany Founded: 1998 (as a spin-off from the University of Applied Sciences Deggendorf) Core Focus: Building automation, smart homes, energy management, IoT gateways, industrial communication. Motto/Philosophy: “Open. Flexible. Reliable.” – They actively avoid proprietary lock-in.

2. Key Technological Specialties Weinzierl is not a generalist PLC manufacturer. Their technical depth lies in three domains: A. KNX – The Backbone They were early adopters and contributors to the KNX standard (ISO/IEC 14543). Their expertise includes:

KNX IP (Routing, Tunneling) KNX Secure (authentication/encryption) KNX IoT (TP & IP to MQTT/JSON/REST) KNX Logic Modules (local scripting without central server) weinzierl engineering gmbh

B. Gateway & Protocol Translation Their flagship competency: turning any building bus into an IoT-friendly data source.

KNX ↔ BACnet (B-BC, B-ASC) KNX ↔ Modbus TCP/RTU KNX ↔ MQTT (for cloud/analytics) KNX ↔ OPC UA (for industrial SCADA)

C. Embedded Linux & Edge Computing Many Weinzierl devices run custom Linux builds, enabling: Headquarters: Töging am Inn, Bavaria, Germany Founded: 1998

Node-RED pre-installed for visual flow programming Python scripting on the edge Docker container support on higher-end gateways Local trend logging and email alerts (no cloud required)

3. Product Portfolio (by Category) Series 1: BAOS (Building Automation Operating System) The heart of Weinzierl’s modern lineup. BAOS devices are KNX IP controllers with a RESTful API. | Model | Key Feature | |-------|--------------| | BAOS 772 | KNX IP Router + 2 MB app memory for logic | | BAOS 774 | Adds microSD slot for data logging & configuration backup | | BAOS 838 | 8 x analog/digital universal I/O for mixed signals (0–10V, 4–20mA, PT1000) | | BAOS 840 | 8 x relay outputs (230V/16A) – direct load switching | Why BAOS matters: You can control it from any programming language (Python, C#, Node.js) via simple HTTP/HTTPS commands. No KNX programming tool needed after initial setup. Series 2: 845 iServices (Industrial Gateways) For system integrators needing multi-protocol access. | Model | Interfaces | Use Case | |-------|------------|-----------| | 845 L | KNX TP, BACnet IP, Modbus TCP | Small building retrofit | | 845 M | Adds RS-485 for Modbus RTU, M-Bus, DALI-2 | Medium commercial buildings | | 845 X | Dual Ethernet, OPC UA server, 4G/LTE option | Remote sites, industrial plants | Highlight: The 845 series includes a built-in web-based logic editor (block diagrams) and supports BACnet B-BC (Building Controller) profile. Series 3: KNX Secure Components

KNX Secure IP Router – First KNX-certified router with Secure Tunneling (AES-128) KNX Secure Power Supply – 640mA with integrated choke and diagnostic LED KNX Secure Coupler – Line/backbone coupler with filtering and telegrams rate monitoring Reliable

Series 4: Software & Tools

BAOS Tool (free) – Configure gateway mappings and logic without ETS ETS App “Weinzierl KNX Logic” – Visual logic editor inside KNX’s official Engineering Tool Software mains™ Cloud (optional) – Remote monitoring, alerts, dashboarding (GDPR-compliant, hosted in Germany)
