Hello,

On RevPi Connect using Codesys, can I assign any of the two Ethernet ports as EtherCAT master?
On RevPi Core I can also use the Ethernet port as EtherCAT master correct?

Thank you

Hi,
RevPi Connect (2 Ethernet Ports)
Yes, either port can be used as EtherCAT master.

Select eth0 or eth1 in CODESYS device configuration under Ethernet adapter settings
Recommended: Use eth1 (lower port) for EtherCAT, keep eth0 (upper port) for network/programming

RevPi Core (1 Ethernet Port)
Yes, but you'll need a USB Ethernet adapter for network access.
Since Core has only one Ethernet port (eth0):
Solution:
Connect USB-to-Ethernet adapter (appears as eth1)
Configure CODESYS to use eth0 as EtherCAT master
Use USB adapter for network connectivity, programming, SSH, and cloud services

Recommended adapters: Realtek RTL8153 or ASIX AX88179 chipsets (good Linux support)

Regards,
Amar
