HI all bro and sis,

I have a 6BK1 621-0AA00-0AA0 firmware:V1.0.0 PN/BACNET gateway in the plc system network.

I would like to get and poll the IO data from the HVAC device system which has BACNET server available and the details as below

Vendor name: Tridium

Vendor Identifier: 36

Model name: Niagara4 Station

Firmware: 4.9.0.198

Unfortunately, I could not find the HVAC device using the siemens BACNET  "Find Bacnet devices.." in device search page. But we are able to find the other 6BK1 621-0AA00-0AA0 server from the Compressors system in this device search page which we are not intended to be connected to.

However, we are able to find the HVAC device using the Yabe Yet another bacnet Explorer application.

May i know any BACnet expert here can give some advices to us?

Here i attached some photos for reference.

thank you.

Thanks,
