AM2432: Is it possible to configure EtherCAT and 2 independent EtherNet ports on one AM2432ALV?

Hi Chunyang,

So you want to configure the device as a 2 port EtherCAT SubDevice?

Regards,

Aaron

Hi Aaron，

    Yes，2 ports EtherCAT subdevice and 2 independent EtherNet ports on one  AM2432ALV.

     Is it possible?

Hi Chunyang,

Correct me if I'm wrong, So you need to run EtherCAT (2 ports) and Ethernet (2 ports) simultaneously (total of 4 ports) ?

• You cannot use both firmware simultaneously.

May I know the use case so that I can have a clear idea of the requirement ?

Regards,

Aaron

Hi Aaron，

          The use case is like that it is a EtherCat slave node(2 ports is need), and it is a Modbus-TCP master(1 port), and it also has a TCP/IP port for service data deliver. 

          So, there are total of 4 ports, is it possible?

          What is the meaning of "You cannot use both firmware simultaneously"

Thanks 

Chunyang

• This is possible.

• Do note that Modbus-TCP master is not supported in our SDK offering.

• I meant you can't run EtherCAT and ICSSG Ethernet simultaneously as both run on different firmwares.

Hi Aaron,

          Thanks for your help, these are really important to me. 

           I know there is no Modubs-Tcp in the SDK, I will implement it by myself.

           I still have 2 details need to confirm with you.

           1, ICSSG0 for 2-port EtherCAT; and CPSW for 2 independent TCP/IP ports. Possible?

           2, For the 2 independent TCP/IP ports, use Lwip-Socket demo. Possible?  (I have read a post which was posted 2 years ago. it said that SDK did not support to run 2 Lwip on 2 ports simultaneously)

            Please confirm the 2 details, and give me guidline as more as possible about them.

Thanks

• This should be possible.

• I'll check this internally and get back to you.

Hi Aaron,

      Are you still looking into this issue?

Thanks
