66AK2G12: Compatibility between different MPNs

Lei the E would be EtherCAT enabled, non industrial software should run on it as is… but we have not supported this specific effort previously.

We always recommend to buy smaller quantities to make sure nothing breaks in your software before purchasing larger qty.

Thank you Kevin.

So do you mean 66AK2G12ABYA60E may be software and hardware compatible with 66AK2G12ABYA60 if we don't use Ethernet function, but it's best to verify in small batches first?

Thank you Kevin, I think this already resolved my issue.

Off topic ，what does IP SUPPORT DESIGNTOR mean？ And what does Alternate IP support mean?

        Thank you Rahul and Kevin.

        We have test 66AK2G12ABYA60E replace 66AK2G12ABYA60, the result is OK on our PCBA based on the test case. 

        As mentioned earlier，  ‘E’ variant adds EtherCAT, but does not take away other capabilities， so I want to know that the added EtherCAT(（Ethernet Control Automation Technology）) function is only related to software？Are there any differences in hardware design between 66AK2G12ABYA60 and 66AK2G12ABYA60E if we don't use EtherCAT? Are there any dedicated or reused hardware pins for EtherCAT that require special handling if we don't use 66AK2G12ABYA60E EtherCAT？

        We are concerned about the potential risks of welding 66AK2G12ABYA60E in hardware circuit design based on 66AK2G12ABYA60.
