Ethernet as the basis for the office and building networks

In addition to data communication for building services, high-performance Ethernet with high transfer rates offers sufficient reserve capacity for image and voice data or multimedia functions. The real-time Ethernet protocol from Beckhoff enables cycle times in the one-digit millisecond range.

For Ethernet TCP/IP a wide range of Bus Coupler are available for the Bus Terminal system. They act as slaves at a higherlevel controller. Based on the Bus Couplers, the Bus Terminal Controllers additionally include an integrated control function that is freely programmable according to IEC 61131-3. Bus Terminal Controllers can, for example, deal with data pre-processing on the individual floors. This relieves the higher-level control system from routine tasks and reduces bus communication. Signals for light, temperature, shade or HVAC control are handled directly in the controller so that if there should be a network failure all functions affecting safety remain intact. Central data – for example for the specification of control set values or security and access control data – communicate with the TwinCAT automation software via the Bus Coupler.

The BC9xx0 and BX9000 Bus Terminal Controllers with Ethernet connection and integrated control functionality are ideally suited for use in building automation. Optionally, these small controllers are also available with an integrated control library for building automation. Ethernet has proven to be reliable worldwide as the communication standard for data transmission with high transmission rates in office networks. Since Ethernet is manufacturer-independent, no special hubs and gateways are required. Ethernet is therefore not only suitable for new buildings, but also for the refurbishment of existing buildings. The technical equipment is complemented by commercially available sensors and actuators and, on the field level, by valves and temperature sensors as standard components.
