BACnet/IP Fieldbus system

What is BACnet/IP?

BACnet (Building Automation and Control network) is a manufacturer-independent protocol that is used for building automation. BACnet enables communication between devices from different manufacturers without special interface adaptations. The high level of interoperability due to standardized, detailed rules and structures for communication exchange is the most important advantage over other communication protocols in the building automation sector. BACnet is often used when it comes to networking smart buildings.

BACnet/IP Gateways

ASi BACnet/IP Gateway

The ASi-3 BACnet/IP gateway in stainless steel provides an interface for a BACnet/IP fieldbus. All gateways also have an Ethernet diagnostic interface for convenient diagnostics. They also include an OPC UA server, which can be used to transfer all process data and additional information to the IT world. One product variant offers data decoupling integrated in the gateway.All gateways also have an Ethernet diagnostic interface for convenient diagnostics.

" yes, max. 4 A/ASi network ":

Data decoupling integrated in the gateway. Cost-effective power for 2 ASi networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.


" yes, max. 8 A/ASi network ":

Data decoupling integrated in the gateway. Cost-effective power for 2 ASi networks with 1 power supply (optionally supply of multiple Single Gateways by 1 power supply).

Operation with short cable lengths with standard 24 V power supply possible.


"yes, optimized for 2 x NEC class 2 power supplies"

Data decoupling integrated in the gateway. Optimized for use with 2 x UL certified 30 V/3 A power supplies with power limitation <100 W (BW4223). In combination 2 separate NEC Class 2 compliant ASi circuits are created.


"no, max. 8 A/ASi network, redundant supply ":

1 ASi power supply per ASi network. Gateway is powered in normal operation from one of the two ASi power supplies.

Should one ASi power supply fail, switching to the other ASi power supply allows all the diagnostics functions to be maintained and the unaffected ASi network continues to operate.


" no, max. 8 A/ASi network ":

1 ASi power supply per ASi network.

Diagnostic and configuration interface

Detects whether the same address has been assigned to two ASi nodes. Frequent error when using a handheld addressing device.

Recognition of duplicate ASi addresses

Checks the ASi line for interference effects such as noise, external voltages, ...

ASi fault detector

Using a C-program offers the possibility to run mini-PLC functions with a gateway.
