New High-Performance BACnet Router and Modbus Gateway Provide Enhanced Security

Contemporary Controls has expanded its line of BACnet routers and gateways to incorporate HTTPS to provide secure Internet communication and protect the integrity of client data. Their resident HTTPS web servers allow for commissioning, status reporting, and troubleshooting using any standard web browser.

With the integration of building management system (BMS) networks within an IT infrastructure, BMS devices must manage a lot more traffic. Each device uses a more powerful processor to accommodate this increased traffic volume. Both models have an opto-isolated EIA-485 port with switchable DIP switches for bias and termination.

The BASrouterSX is a high-performance BACnet router that provides stand-alone routing between BACnet networks such as BACnet/IP, BACnet Ethernet (ISO 8802-3), and BACnet MS/TP. This multi-network router features an MS/TP status webpage with a graphical network map that provides real-time status of all BACnet MS/TP devices on the network. It has advanced features, such as MS/TP slave proxy support with auto-discovery and diagnostic MS/TP frame capture for Wireshark® analysis.

The BASrouterSX-GSA is a GSA-compliant model which has been tested and approved for use in U.S. government buildings.

The BASgatewaySX Modbus to BACnet Gateway provides gateway functionality between Modbus Serial (RTU or ASCII), Modbus TCP and BACnet/IP. The gateway supports up to 200 devices and 2000 mapped points and features virtual routing that allows each connected Modbus device to appear as an individual BACnet-compliant device. Using HTTPS webpages and a resident database of common Modbus device profiles, Modbus data points from Modbus Serial or Modbus TCP devices can be mapped to BACnet objects.

The BASrouterSC is a BACnet/SC router that also supports BACnet/SC communicating to MS/TP, BACnet/Ethernet and BACnet/IP devices. It can be used to improve the security within a BACnet system by utilizing BACnet/SC at the Ethernet level and allowing MS/TP at the device level. The BASrouterSC can take a BACnet/IP-only device to the BACnet/SC network. The BASrouterSC also supports BACnet/Ethernet communications.
