Sedona Open Controllers

May 2015 - The BAScontrol22 Unitary Controller is a good example of an open controller in that it embodies the attributes of an open controller as defined by Contemporary Controls. It is BACnet/IP compliant and incorporates a Sedona Virtual Machine. It can be programmed using Niagara Workbench or with a Sedona Tool. It is available to any systems integrator without restriction.

By having an Ethernet connection, the BASC22 can easily connect to Niagara Workbench or a Sedona Tool for programming or to a web browser for configuration. A built-in 10/100 Mbps Ethernet switch allows for a daisy-chain connection to the next-in-line controller or to a building supervisor. Besides having 66 Sedona components from Tridium, it has 100 custom components from Contemporary Controls. These include 48 web components that can be viewed and manipulated by a web browser, and 24 virtual points that can be read or written by a BACnet client.

The BAScontrol20 Demo Board is ideal for training and simulation by having inputs and outputs pre-wired to physical points. Applications can be tested before being deployed in the field.
