In a test measuring time synchronization accuracy, an AM6442 starter kit was connected to a Keysight NovusONE as the grand leader.

For the test setup measuring baseline transmit timing, a small network of three Sitara AM2431 MCU devices as EtherCAT subordinates and a Sitara MPU device running CODESYS®, an EtherCAT Main software stack, as the controller. There were two Sitara MPU devices tested, the AM6412 as the lower end controller, and the AM682 as the higher end controller.

For the comparison with a non-EtherCAT setup with the TSN feature of EST applied, an EtherCAT network with a Main sending to a Subordinate was simulated by an AM625 starter kit in place of the Main and an AM6412 in place of the Subordinate without actually setting up a true EtherCAT network.
