This International Standard specifies the characteristics of software and functions used in Building automation
and control systems as well as a method for documentation of the design. It gives guidelines for the engineering.
It specifies a template for documentation of plant/application specific datapoints and functions, called BACS
function list in annex A.
The informative function block examples explain a method to display the referenced functions in system
documentation; they do not standardize the method for programming functions and applications.
This International Standard covers the following:
Requirements and definitions regarding BACS and application software, generic function types for plant/project
specific applications and engineering functions for building controls and operations. It provides communication
functions for the integration of other dedicated special system processes. The functional requirements in this part
of the standard are subdivided as follows:
System management and application software:
This clause describes the requirements for plant independent system and human system interface programs
related to a project, including the operating system. This standard does not dedicate the following system
functionality to any particular hardware, e.g.:
system diagnostics, watchdog, redundancy, time keeping, access control, log lists;
point identification, event message handling, print control;
database, statistics, data archiving, remote access;
system communications.
Human system interface (HSI), point information presentation, graphics, alarms, time scheduling
Engineering process and tool software:
This clause describes the requirements for configuring of the hardware and control strategies, the system
management, and the commissioning process.
BACS application processing programs and plant/application specific function types:
This clause describes the requiremen (...abbreviated)
Diese ÖNORM legt die Merkmale der bei Systemen der Gebäudeautomation eingesetzten Software und Funktionen sowie ein Verfahren für die Dokumentation der Planung fest. Weiters enthält diese ÖNORM Leitlinien für die technische Bearbeitung. Anhang A legt eine Vorlage für die Dokumentation der anlagen-/anwendungsspezifischen Datenpunkte und Funktionen, genannt GA-Funktionsliste, fest. Die informativen Funktionsblock-Beispiele dienen zur Erläuterung eines Verfahrens, wie die entsprechenden Funktionen in einer Anlagendokumentation darstellbar sind.
