Introduction
Interworking between devices signifies that these products send and receive datagrams and are able to
properly understand and react on them. This ability is provided without additional equipment (like
translators or gateways).
NOTE Media couplers are needed if different media are used in an installation.
The market requires Interworking for a multi-vendor approach, this is, products from different
manufacturers can interwork in a certain application segment or domain as well as across different
applications (cross discipline Interworking).
Such an Interworking is only possible if a set of requirements is complied with as defined in an
Interworking model. For this, Functional Blocks need to be defined, which in turn specify Datapoints and
the communication mechanisms to be used. Such a set of requirements is referred to as "Application
Interworking Specifications" (AIS).
AIS allow Interworking independent of the implementation by a manufacturer. Besides the advantages for
the user (multi-vendor offer) Interworking also allows a broad OEM market and easy market access for
niche-products providers. Furthermore Interworking allows the establishment of a common market
infrastructure (i.e. common configuration tool, training, etc.)

1 Scope
This European Standard gives general guidelines and recommendations to ensure interworking between
HBES devices made by different manufacturers. It also contains design guidelines for the design of
Functional Blocks and new datapoint types, the building blocks of HBES interworking.
In this way, the standard can be used as a basis to design application specifications relative to an
Application Domain. If designed and supported by a large group of manufacturers, such application
specifications will ensure to end customers a high degree of interoperability between products based on
the HBES Communication System of different manufacturers.
This European Standard is used as a product family standard. It is not intended to be used as a
stand-alone standard.
