FB_sACN_Source
The FB_sACN_Source is a specialized TwinCAT 3 FUNCTION block designed TO generate AND transmit sACN (streaming ACN) data FOR a specific DMX universe. It automatically formats sACN packets with essential details like source name, unique ID, DMX channel values, AND sequence numbers, sending them AT a configurable period. BY integrating with an I_sAcnCommunicator INTERFACE, THIS block efficiently handles all the low-level UDP network communication AND socket management, allowing you TO focus purely on providing DMX data AND source configuration.
