The example contains two PLC programs and a Lightjams project file (www.lightjams.com). The example supports general sending and receiving of sACN frames. The individual function blocks of the example are explained in the Programming section.

Thanks to several network interfaces the sACN slave is able to respond to several UDP telegrams and therefore several sACN masters. The sACN masters are represented through a further PLC program and a Lightjams project.

The TwinCAT supplement TwinCAT TCP/IP Server is required for the example.

Based on this example, the user data of the sACN frame can be linked with any PLC variables. Links enabled by the modular Beckhoff control system include
