Description

The TIDEP0079 reference design 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.

Features
  • Examples for implementing EtherCAT master on both the Ethernet switch (CPSW) and the PRU-ICSS Ethernet ports for design flexibility
  • EtherCAT master on PRU-ICSS featuring Time Triggered Send
  • Highly portable acontis EC-Master stack
  • Cycle CPU consumption of less than 30µs is achieved for both the Ethernet switch and PRU-ICSS Ethernet ports
  • EtherCAT class A or class B master stack according to ETG.1500 specification
  • This reference design is tested on the TMDXIDK5728 board and includes documentation, software, demo application, and HW design files
