Building automation and control systems — Part 5: Data communication protocol

ISO 16484-5:2007 defines data communication services and protocols for computer equipment used for monitoring and control of heating, ventilation, air-conditioning and refrigeration (HVAC&R) and other building systems. It defines, in addition, an abstract, object-oriented representation of information communicated between such equipment, thereby facilitating the application and use of digital control technology in buildings.

• ISO 16484-5:2007 provides a comprehensive set of messages for conveying encoded binary, analog, and alphanumeric data between devices including, but not limited to hardware binary input and output values, hardware analog input and output values, software binary and analog values, text string values, schedule information, alarm and event information, files, and control logic.
