Standards-based systems - Systems that use coordinated protocols so that devices from different manufacturers can be used. However, practice shows that there are some differences at versions.

Cooperations and alliances - several manufacturers have coordinated their BUS protocols so that manufacturers can be mixed.

Proprietary systems – systems which are manufacturer-specific. The use of these systems means a high dependency on a manufacturer only. Depending on the product range, there is a closed, complete system. A connection to other systems can possibly be established via gateways.
