LM supports BACnet so this will work on both platforms. If controller is on different subnet we also support FDR, see BBMD settings in BACnet settings.

Hello,
I am trying to integrate a device running on the 192.168.63.0/24 network with a BACnet/IP system on the 211.67.63.0/24 network. The setup is as follows:

• BACnet server device: 192.168.63.162 (should register as Foreign Device)
  
• BBMD (BACnet client/PLC): 211.67.63.171
  
• Port: 47808
  
• Device ID: 127001
  

Configuration
On the server side (192.168.63.162), I configured:

• BBMD IP = 211.67.63.171
  
• BBMD Port = 47808
  
• TTL = 180 seconds
  

Tests performed
I have a PC in each network. I tried to add a special firewall rule on port 47808, and even to deactivate the firewalls on both PCs

• With Wireshark running on the server’s network interface:
  • I can see “unconfirmed-req I-Am device, 127001” at startup.
    
  • I do not see any BVLC: Register-Foreign-Device (function 0x05) messages sent to 211.67.63.171.
    
• With Wireshark on the BBMD side (211.67.63.0/24):
  • The BBMD sends Who-Is requests for device 127001.
    

It seems to me that it can not be a network admin issue since the request is not even issued as we have  no Register-Foreign-Device frames visible. 
Is there something that should be done to activate the FDR function, appart from filling the 3 last fields of the BACnet server setting page? 

Kind Regards
