Rees Scientific integrates additional features to its 1021 software, increasing safety and reliability. New BACnet compatibility allows the software to act as a BACnet server and/or a BACnet client over any TCP/IP compatible network. Users can utilize the 1021 software functionality without duplicating sensors or infrastructure. The Rees System can read any BACnet compatible sensor while the building management system (BMS) actively communicates with the device. It can also transfer data to and from the BMS.
