This is a configuration example using the IP Gateway KNX/BACnet N143/01 from the Siemens GAMMA portfolio to integrate KNX S-Mode networks into Desigo systems.
The KNX/BACnet Gateway N 143/01 on IP offers an easy way to integrate KNX S-Mode devices via simple group addressing into Desigo PXC4/5/7 automation stations. As BACnet-application specific controller (B-ASC), the gateway acts between KNX TP and BACnet IP for up to 250 BACnet objects and up to 455 BACnet COV subscriptions. If a communication across the KNX segments is required, KNX Line coupling units have to be used (see graphic above). |
Project engineering
Mapping of KNX communication objects to BACnet
The following BACnet object types are supported by this gateway:
- Binary Input
- Binary Output
- Binary Value
- Analog Input
- Analog Output
- Analog Value
In ETS, the following object types can be configured and mapped to BACnet (for more details, see A6V10466141)
- 1 bit
- 1 Byte unsigned, signed
- 2 Byte unsigned, signed, or float
- 4 Byte unsigned, signed value, or float
Engineering with ETS and ABT Site
- Add the IP Gateway KNX-BACnet N 143/01 as device to your ETS project.
- Define a proper device name and a device description in "Optional settings".
- Define objects on the gateway with a proper naming (do not use generic names). Important: Independently of having an input or output signal, set "Transmission direction" always as bidirectional KNX <--> BACnet (value).
- Generate the EDE file via the web interface of the IP Gateway.
- In ABT Site, import "BACnet references" using the EDE file.
