Hi,
Anyone an idea why LM5 bacnet broadcast is going off line?
BACNET controller can see broadcast signals and all of a sudden LM bacnet broadcast goes offline

Hi,
Please drop some more info. What exactly do you do? What firmware do you have?
Make sure don't use server and client on same device.

Hi,
Type of LM and firmware below:
HW: LM5 Lite (i.MX6)
SW: 20200116
packages:
There's an export of BV from KNX to bacnet and feedbacks coming from BACNET.
Server is enabled, if not Johnson Control BACNET controller doesn't see LM.
We were able to detect LM from Johnson Control's BACNET controller and also exported objects when LM is restarted.
After some minutes Johnson Control's BACNET controller indicates that LM is off line.
Is it possible that LM goes offline because there's no stauts change in the BV?

Can you access the Lm when Johnson loses connection with it?
When Johnson lose control, have you tried using a third party Bacnet browser like Yabe ?
That there is no COV wont put the Lm offline.
RE: BACNET off line - Geert - 07.12.2020
I can still acces LM when Johnson loses connection.
I tried with third party browser but can't find LM

Install System load app on LM and check if BACnet process is still working. If not then possibly it has crashed for some reason. Can you provide remote access to your LM?
RE: BACNET off line - Daniel - 07.12.2020
Did you try changing device ID?
What happen if you disable and then enable BACnet server on LM?
RE: BACNET off line - Geert - 07.12.2020
Daniel,
Yes I changed device ID.
When I disable BACNET server on LM bacnet can't see LM, enabling server results in detection LM by BACNET.
Can you send me system load app to install by file. Access to app store fails from company network.

It's possible for access. Can we send PM?
RE: BACNET off line - admin - 07.12.2020
Yes, please send PM
RE: BACNET off line - admin - 09.12.2020
Thanks for the access. It looks like your BMS or some other BACnet device is sending a lot of "Who-Has" requests. This might cause a delay for any other requests or even dropped packets if there are too many requests sent at once. See if you can disable this.
