demonstrates an EtherCAT® master interface running on the Sitara™ AM572x processor using the EC-Master stack from acontis. This EtherCAT master solution can be used for EtherCAT-based PLC or motion control applications. EtherCAT master is profiled on both the Ethernet switch and the PRU-ICSS Ethernet ports of the AM572x processor to give designers flexibility to use any of the two switch ports or four PRU-ICSS Ethernet ports on the device. The EtherCAT master implementation can achieve less than 100μs cycle times for both the switch and the PRU-ICSS Ethernet ports. Time-triggered send (TTS) can be enabled on the PRU-ICSS to reduce jitter, achieve shorter cycle times, and reduce latency in cases where distributed clocking is not used.
