AM3357: EtherCAT delay

Part Number: AM3357

Hi Experts,

I have two questions as follows:

1)Could you please let me know about delay time until IO start output the data after the EtherCAT Master send the data with PDO and the Slave receives?
2)How long does it take if the data comes into IO port and it is returned to the Master?

I have found the article on e2e below.,

> This is all assuming the Slave is running in DC mode. And readings we get for 1ms cycle time is

> 1) PLC to Slave -> ~0.3 cycle

> 2) Slave to PLC -> ~1.7 cycles

It seems that it takes approx. 2ms with TI's Sitara processors.
Please let me clarify about the actual delay time whether it might be much shorter I hope.

Thank you very much for your kind check.
Best regards,
Hitoshi
