Introduction

Crestron Electronics with head office in Rockleigh (www.crestron.com), New Jersey (USA) is one of the market leaders for AV control systems. In addition to AV control units, building management components can also be integrated. The following article describes data exchange between Crestron controllers and Beckhoff hardware via Ethernet.

For the Crestron control centres, blocks (user modules) are available for data exchange via TCP/IP. The TwinCAT Crestron Server must be installed on the Beckhoff controller. A Crestron controller can call write and read commands and a Beckhoff controller can write data to the Crestron controller or read data from it.
