Hello,
I have a questions related to BacNet driver. Can I create more that one driver ? Also how many devices one single driver can support ?
Thank You,

Re: BAC Net
Hello Walter,
Yes, it is possible to start multiple WinCC OA BACnet drivers simultaneously on the same server, however the following notes must be considered:
-> The UDP port which is used (opened) by the BACnet driver for the communication (by default 47808) can be used only once per server IP address.
So for example if you want to start two BACnet drivers with the same port 47808, then this two drivers cannot use the same server IP address.
This means that if you want to start multiple BACnet drivers, these drivers either have to use different UDP ports or different server IP addresses.
Please note that it is also possible to assign a (physical) network adapter multiple (logical) IP addresses.
For a detailed description of the BACnet driver configuration (UDP Port, used server IP address, Network-ID, etc.) please refer to the
chapter "Drivers -> BACnet -> BACnet driver config file" of the WinCC OA Online Help.
You have to use the config file section [bacnet_] for the configuration of the individual BACnet drivers, whereby
stands for the particular driver number.
-> A single BACnet driver can only communicate with ONE single BACnet Network-ID.
-> A single BACnet driver has no limitation for the number of supported devices, however the devices of a single driver must have the
same BACnet Network-ID.
With best regards,
Christian Boehm
