The BAScontrol22S is a 22-point unitary controller which supports BACnet client/server operation over BACnet/IP or BACnet MS/TP. The controller complies with the B-ASC device profile having a convenient mix of 8 universal inputs, 4 binary inputs, 4 analog outputs, and 6 binary outputs. Unique to the unit are 48 web components which link Sedona wiresheet readable/writeable data to webpages, and 24 virtual points which link Sedona wiresheet readable/writeable data to a BACnet client. The device is fully webpage configurable and freely programmable using Sedona's function block programming methodology of assembling components onto a wiresheet to create applications. The unit can be programmed using the BAScontrol Toolset. The controller is powered by a 24VAC/VDC source. Rugged design, low profile, and wide temperature operation make it suitable for indoor or outdoor use. The BAScontrol22S utilizes a 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
