From 11 to 15 March 2019, around 190,000 visitors came to the Frankfurt Exhibition Grounds to find out more about innovative building solutions based on the networking of different systems at the world's leading trade fair for water, heating and air conditioning. With TwinCAT 3 Building Automation, Beckhoff presented its software tool for building automation at the ISH. It bundles all building services on one platform: from heating, ventilation and air-conditioning to shading, lighting and energy data acquisition. This results in synergy effects enabling energy-efficient building control and at the same time significantly simplifies engineering and control. Other highlights at the Beckhoff booth included TwinCAT Speech, for processing voice signals in smart building control, and the implementation of BACnet Revision 14 in TwinCAT. It provides the user with improved alarm processing options.
