I tried to downgrade my AXC F 2152 from 2019.6 to 2019.3. But now the D-LED is constantly orange.An access to the PLC by PLCnext Engineer is not possible, by using WinSCP an access is possible.
I tried to update to version 2019.6 again and the PLC starts working again.
But this version seems not to work correctly when using Profinet and/ or the local bus.
I also did a factory reset befor my second downgrade attempt but it does not work.
Can you help me with this and tell me what I can do to make 2019.3 work again?
