I was able to access to this old PLC unit we had via the communication cable, e!cockpit had issues trying to identify this device (FW 17), I decided to use Wago Ehternet settings and had a communication via serial (Ethernet unavailable despite I could find the IP by guessing), then I downloaded Wago-FBC-Update and tried to run the following firmware (WAGO-FW0750-0842-V050502-IX19-S.zip) by following the instructions and stopped at 20%, left it alone for a long time (1 day) and finally restarted it…
Now the I/O orange LED is blinking twice then one time and then the two previous times… Now no comms at all, neither Ethernet or serial.
