Hi,

Typically ETHERCAT applciation use Force Mode, 100M, full duplex and fast link drop enabled. All these configurations can be done using HW configurations.

Hi Geet,

Thanks!
How about EEE_EN and AMDIX_EN (SD_EN)?
Should be Enable or Disable?
Thanks!

AMDIX_EN is typically disabled as it increases the link-up time.

EEE_EN : It stands for Engery Efficient Ethernet to lower the power consumption of Phy when not used. Typically EtherCAT systems are real time and don't use this feature. hence disabled.
