Contemporary Controls has always supported open protocols like BACnet, but BACnet does not provide control, only a standardized method for communications. Having BACnet is not sufficient when you are locked out of a job due to a proprietary programming language, licensing restrictions, or a proprietary programming tool only available to "partners". The BAScontrol Series is Contemporary Controls' way of providing a truly open controller by having:
The BAScontrol Series utilizes a powerful 32-bit ARM7 processor with 512 kB of flash memory plus a 16 Mbit serial flash file system for storing configuration data and an application program. By operating at the BACnet/IP level, the BAScontrol20/22 can share the same Ethernet network with supervisory controllers and operator workstations. Each unit can be configured for a fixed IP address or can operate as a DHCP client receiving its IP address from a DHCP server. A real-time clock with a super-cap backup allows for creating local schedules. A 10/100 Mbps Ethernet port supports protocols such as BACnet/IP, Sedona SOX, HTTP and FTP. The device is fully web page-configurable, and freely programmable using Sedona's drag-and-drop programming methodology of assembling function blocks (components) onto a wire sheet to create applications. Universal input Type II and type III 10 kΩ thermistor curves and a 20 kΩ thermistor curve are resident in the unit in addition to analog input, binary input, and pulse input channel types. Current inputs can be measured using external resistors. Contact closures require a voltage-free source. Binary inputs and outputs as well as analog outputs require no configuration. The unit can be programmed using the Sedona Application Editor (SAE) programming tool as part of the free BAScontrol Toolset. The unit is powered from a 24 VAC/VDC source. Rugged design, low profile, and wide temperature operation make it suitable for indoor or outdoor use.
