1.1 Field of application
The FND is a communication protocol for building automation and control systems on the
management net level. It is used for data transmission between a central station and one or more
autonomous islands of automation stations.
The standard specifies the interface of the central station and of the island of automation stations
for communicating with each other. The network used for internetworking these systems is not
part of this standard.
The communication objects defined in this standard correspond to the basic functions of building
automation and control systems. Therefore the information needed by the central station is
available from automation stations even if the vendors of the different systems are not identical.
