What happens?
After a firmware downgrade, it is not possible to establish a connection to the Lenze controller c750 via EASY Starter or PLC Designer, for example.
When does the behaviour occur?
The behaviour described above only occurs with the Lenze controller c750 after a firmware downgrade from V1.7 to V1.6.
Which products are affected?
Cabinet Controller c750
Short-term measures:
