Regarding the problem on the Flywheel PLC (see here), we entered UC1 under the supervision of Daniel M. and Koji (11:16 local time).

First we checked the LEDs of the black Ethernet cable. LINK in green was constantly ON and ACT in orange was blinking.

Then, we disconnected the black cable and reconnected again after 20 sec (11:30). But, the LEDs of the PLC in the right side were OFF.

Finally, we removed the two red power lines connected to the PLC with a screw driver and reconnected again (11:52). The LEDs of the PLC turned ON. The UC1 web page was back (12:08).
