Hello
In this case, what is the needed device ?
Standard Ethernet router ?
Spécific bacnet device - BBMD ?
Spécific bacnet device - FDP ?
We talked about it during ISM 2011 (I have looked the ppt file) but it's not very clear in my head
Thanks

Hello,
In my hopinion, this slide is not very clear about the architecture that you want to do.
- What is the green line? It's an Ethernet network or a different network type like BACnet MS/TP (serial) or something else (LON...)?
If the green line is an Ethernet network (separated from the one which PcVue server is located due of a different subnet/VLAN or a VPN router in the middle) you need to use the BBMD functionality. This because BACnet is based with Broadcast packet which are blocked by Ethernet routers (don't confuse with BACnet router).
I suggest you this document: http://www.chipkin.com/files/pdf/Bacnet%20For%20Field%20Technicians.pdf
Go to page 8
Hope it help,
Kind Regards

Thank you
My case is : Ethernet network (separated from the one which PcVue server is located due of a different subnet/VLAN or a VPN router in the middle)
So if I understand I just need to configure BBMD but don't need specific router ?
I will read you document
Best regards

Hello,
Yes, you need BBMD.
If you have network A and network B (separated) you need to:
- configure a device, in network A, for using BBMD (just one it's enough, lot of router and devices support that)
- the same of network B (Our BDS stack can act also as BBMD gateway, so you don't need a real hardware device on that network - PcVue it's enough).
- Allow IP address of BBMD device in network A to be seen from network the one in network B (VPN, NAT...)
Honestly I don't have a real experience on that, so if you plan to use PcVue as BBMD for doing that your comments are welcome to share your experience.

Hello,
I had a doc for the BBMD and FDT from Jerome when I qualified the BACnet long time ago, it explains the both architectures. See attached file for detail.
