BASautomation Building on BACnet®


Contemporary Controls is unique in the industry by supplying products that maximize the benefits of both BACnet and Ethernet. BACnet, an internationally recognized building automation standard, can take you from the field level to the Internet. With buildings pre-wired for Ethernet, BACnet/IP is the ideal choice for building automation systems. Ethernet is everywhere and understood by many. With BASautomation – Building on BACnet and CTRlink – Ethernet Built for Buildings, Contemporary Controls provides the system building blocks for networking, integrating and controlling your building.

BASautomation BACnet routers link IP networks to BACnet MS/TP. Gateways adapt other protocols such as Modbus to BACnet. BACnet/IP controllers Powered by Sedona Framework and Niagara Framework do the work. Once on Ethernet, the CTRLink family – with its collection of managed and unmanaged switches, media converters, wired and wireless IP routers – can complete the connectivity process. With locations around the world, and a reputation for technical support, Contemporary Controls will make your building automation projects successful.

The BASview is a stand-alone, embedded, web-based graphical interface for building automation and process automation systems. It can be accessed from any web browser - providing client functionality to any BACnet/IP or Modbus TCP system.


There are many BACnet controllers on the market that utilize a closed/restricted programming tool with a proprietary programming language. Our concept of a truly open controller is one that uses BACnet - an open protocol, an open source drag and drop component based programming language - Sedona, as well as an unrestricted programming tool - our free Sedona Application Editor. Our BAScontrol family of products provide all of the features necessary for a truly open controller.


The BASrouters are multi-network routers used to route messages between BACnet/IP, BACnet Ethernet and BACnet MS/TP networks. Three versions are available - two DIN-rail mounted units for fixed installations and a portable unit for commissioning and troubleshooting.


Gateways map individual Modbus registers into BACnet objects. With the BASremote, all connected Modbus devices appear as one BACnet device object with a collection of object points representing the various Modbus registers. Using the concept of virtual routing, the BASgatewayLX treats each connected Modbus device as a separate BACnet device with object points representing only those registers of the addressed device.

I/O Modules

For those installations that support a fieldbus solution such as Modbus RTU or BACnet MS/TP, Contemporary Controls provides solutions for expanding the number of I/O points in the field. These compact cost-effective modules are available with analog and digital inputs and outputs in varying combinations.
