Building automation and control systems (BACS) - Part 3: Functions

Scope

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 data points 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.
