Thanks for your answer! Yes, I can scan Festo PLC via remote Edge Gateway on the Pi. And, yes, I've tried both ways: default scan(UDP), and plc_ip:11740(plc is also visible and with "green status")
Hi All, I am trying to remotly connect to Festo PLC(cpx-e-cec-m1 to be exact). My setup consists of CODESYS 3.5.16.10 and an OpenVPN connection to OpenVPN server. At the other side I have Raspberry Pi4 with Edge Gateway for Linux(3.5.16.10) and Festo PLC. I am able to connect to remote Gateway and Festo PLC is also active, but when I click connect CODESYS returns "connection failed" error. All ports on Festo PLC are forwarded. Do you know what could be the issue here? Thanks, Alex
