RevPi Core 3+ connect to EtherCAT IO

Hello,

For the CODESYS application, I tried to control EtherCAT IO via RevPi Core 3+. to achieve it, RevPi Core 3+ is installed with a USB to WIFI module for Ethernet connection. the Ethernet port of RevPi Core 3+ connects to the EtherCAT IO module. But I can't scan for EtherCAT devices in CODESYS, why is this? I think this is the right logic to work.

Best regards,
Cade

Hi Cade, does the error appear regardless of whether you want to connect to Codesys via Ethernet or WiFi?
Can you show the topology briefly with a small sketch?
Are you using the right versions of all involved components? Have a look at this checklist that can help you:
