I am using X-Soft CODESYS on an EATON-Panel at the customer. It is connected via a Secomea-Modem for remote access. 4 Month ago, there was a connection and I was able to upload the software.
But now I can not access the PLC anymore. The device is not responding.
The Settings of the Secomea Modem are still the same:
When I try to ping the device, there is a reply.
I also watched it in Wireshark: first the ping and then I tried to connect in the CODESYS IDE
So some Questions:
1. Am I doing something wrong in general?
2. Why is the Ping working but not the CODESYS connection?
3. How can I establish a workinmg connection?
4. I often read about Gateway on a raspberrypi. Do i need a Gateway? I think with the Secomea Modem, the connection should be possible as it was directly pluged to the PC
Thank you in advance!
