ABSTRACT:
A building automation control system for use in a building having an IT network is disclosed. The building automation control system includes at least one BAS controller connected to the IT network and at least one BAS device located within the building and connected to the at least one BAS controller through the IT network. Further the system may be configured to use standards-based IT technologies over the IT network to manage the at least one BAS device. The standards-based IT technologies may include DHCP to obtain IP addresses and network parameters of the BAS devices, DNS to provide a mechanism for associating the BAS devices with human-friendly names, a distributed mechanism for storing the names, and a method for locating the BAS devices by resolving names and IP addresses, SNTP to synchronize time on the BAS devices, SNMP to monitor the BAS devices and report alarms, SMTP for delivery of e-mail alarms, web-services to provide Internet-friendly communications, and standards-based IT security mechanisms to protect software of the BAS devices.
