Fig. 5 The building management system is the central switching point for all buildings that are networked with Ethernet.
Each building acts as a separate data acquisition unit: Via the Beckhoff Embedded PC with integrated Ethernet interface the
data can then be made available to a central building management system. This enables the local data to be available directly
in the individual systems as well as centrally. This principle significantly reduces the engineering effort and keeps the data
management transparent.
Another typical practical example is error-free meter reading at short notice when a change of tenants occurs, while
safeguarding the privacy of the tenants. Remote reading enables electronic data acquisition with minimum manpower
requirements (reduction of reading errors) and speedy further processing (compiling of statistics, invoicing, etc.).
