When entering the menu “I/O/C-reserv”, I get the message “CIO connection failed”.

Reason
There is a CIO activated in the base menu, but there is no connection to the CIO.

Solution
If the lift has a CIO, please check the connection to the CIO. If there is no CIO, please have a look in the base menu -> ports -> ser. ports -> ports CAN -> CAN Geräte -> CLK/CAP/CIO -> port CIO -> device: on/off Please deactivate the CIO and the message is gone.
