Simply explained: What is a bus system?
A bus system is like a data highway within an electronic system. This is a shared management or a networkvia which various devices and components can send and receive data. Instead of each device being directly connected to every other device, they all share this one communication linewhich simplifies simplifies the cabling and increases efficiency.
Why is it called a bus system?
The term “bus” comes from the Latin word omnibuswhich means “for all”. In electronics and data processing a “bus” on a common communication mediumwhich is used jointly by several components to transmit data. A bus system enables different devices or components, to exchange data via a common linesimilar to a public transportation bus carrying different passengers on a common route. common route transported.
What bus systems are available?
In building automation and electronics in general, there are various types of bus systems in buildings. Here is an overview:
BACnet/SC provides the previously missing and increasingly important IT security in building automation
BACnet Secure Connect (BACnet/SC) adds an additional protocol layer to the existing BACnet standard. It retains full compatibility with existing BACnet networks, while at the same time enabling improved interoperability between different building automation systems.
The network and security mechanisms used are based on modern IT standards and create significantly more flexibility when setting up and adapting networks as well as in configuration and change management during operation. However, certificate management represents a key challenge for the industry: All BACnet/SC-capable devices require valid certificates, which must be renewed regularly in order to ensure permanently secure data communication.

How can bus systems be subdivided?
Bus systems can be subdivided in various ways. You will find the most common subdivisions in the following section:
