bacnet will not start

[tom77]

I have a problem with the BacNet server
I have set this and Network => Bacnet Settings
The device ID is unique
no Bacnet client is installed on the LM
the firmware is 20240426
in Yabe all existing Bacnet devices are displayed but not the LM
Does anyone have an idea where the problem is?

best regareds

Lets start from some basic things. Share a screenshot of bacnet settings and bacnet objects.
Screenshot of Running processes will be also helpful.

here are my settings.
is a test logic machine also have the problem on the 2nd LM, but it has been in the system for 8 years, I have also updated it to the current firmware and it also has the problem just to be sure I then used a 2nd new LM for testing.

Try changing the ID as this is the default value and you may have a conflict.

I have already tried this, but unfortunately it does not help

Check network settings. Network mask must be the same on all devices for BACnet broadcast communication to work.

I have switched the logic machine to DHCP and a FRITZ!Box also assigns the addresses to other BacNet devices that I see with Yabe

To be sure I just tried DHCP settings with bacnet and it works fine. Your router does not like LM for some reason. Can you try using static IP?

Yes, we have also tried it and the old wiser for knx has also appeared on bacnet .....
but no longer with the latest lm firmware

Which IP range are you using?

[tom77]

Which IP range are you using?

139.64.101.x
255.255.255.0

[admin]

139.64.101.x is a public IP range. You should use a private network range instead.

ok thanks that's the problem,
but the big problem is that there are 50-60 devices communicating in this network via bacnet and i can't change that
and the old firmware could apparently do that too
is there a possibility to activate it again ?

[Daniel]

Downgrade the firmware or contact SE. There is nothing we can do as you use W4K.
