B3075 – Cimetrics B/IP to B/IP BNSD

The B3075 is a second-generation BACnet/IP to BACnet/IP Network Segmentation Device (BNSD) that enables BACnet communication between two physically separate IP net-works. It is designed to meet the requirements of demanding customers with a large number of BACnet/IP devices. The Network Segmentation Devices include new management, diagnostics, and remote event logging functionality that can be selectively enabled. Based on the Cimetrics BACstacTM, the standalone BNSD can reliably process a high volume of net-work traffic.

FEATURES 

• Three Ethernet ports: Two for BACnet segmenting and a dedicated port for configuration. 

• 1 IP address from IT (Fixed or DHCP) on “ Customer” port of the Network Segmentation Device, connects up to 250 BACnet/IP devices on the “Private” network. 

• Network Segmentation Device passes only BACnet UDP traffic. All non BACnet traffic is blocked. IT has no visibil-ity of Private network.

• Support for OpenVPN Community Edition enables non-BACnet communication with devices on the “Private” Ethernet network from the “Customer” Ethernet network.

• Wireshark-compatible packet captures on both BACnet interfaces simultaneously.

• Supports HTTPS communication for secure browser-based configuration.

• U.S. General Services Administration approved.

BACnet DETAILS 

• BACnet message routing as defined in Clause 6.6 of ANSI/ASHRAE Standard 135, Protocol Revision 16 

• BACnet/IP communication on two Ethernet ports 

• Optional BBMD with Foreign Device support on customer port

TYPICAL APPLICATION SCENARIOS 

The B3075 application scenarios: 

 Customer’s IT department cannot allocate enough IP addresses on the IT network for the BACnet/IP devices. 

 Certain BACnet/IP devices should not reside on the same IP network with customer’s IT systems for technical or policy reasons. 

 Customer’s IT department will not allow UL864 switches or daisy chained and ring connect devices to connect to the IT managed network.

Deploy Your Network — BACnet/IP to BACnet/IP Network Segmentation: 

Cimetrics BACnet/IP to BACnet/IP Network Segmentation Device routes BACnet packets between two separate IP networks. A typical deployment scenario is shown below, in which there are multiple IP networks containing BACnet-compliant devices that need to communicate with one another, and many of the BACnet devices are connected to one or more private IP networks utilizing private IP addresses.
