Use
The PXG3... BACnet router connects a BACnet/IP network to a BACnet /LonTalk
network (PXG3.L only), and/or a BACnet MS/TP channel. BACnet objects are
simultaneously transmitted among any and all networks.
Router functions
The PXG3... BACnet router transmits BACnet protocol between a BACnet/IPv4
network, a BACnet/IPv6 network, a BACnet/LonTalk network (PXG3.L only), and a
BACnet MS/TP channel. BACnet objects are simultaneously transmitted among
any and all networks.
Broadcast Management Device, used to distribute BACnet Broadcast messages
across IP Routers.
The BACnet Router possesses a Device Object and can be operated by a BACnet
Client. Present operating state, date and time as well as statistics on sent
packages can be viewed via web server.
The BACnet router can serve as a Slave Proxy for all slaves that are connected to
the MS/TP network. I.e. it sends a I-Am message to all MS/TP slaves, answering a
Who-Is message.
Simple Network Management protocol MIB-2, for monitoring and diagnosing the
network interface of the BACnet router.
Supports setup of a BACnet network over a NAT device. Additionally, remote
access from a public network to BACnet devices in a private network is possible.
Important
: the public IP address must be static.
For security reasons we recommend to use VPN tunneling with BACnet NAT.
For details see standard 135-2012 Annex J.
When routing between BACnet/IP and BACnet/IP within one IP network, the
address of the BACnet router must be the same in both BACnet networks. The
difference of the BACnet network is done by using different BACnet UDP ports.
