What happens?
After updating a controller in the device tree of the PLC Designer the Profinet node is deleted.
When does the behaviour occur?
The behavior occurs when a c520 V1.4, c550 V1.4 or c750 V1.4 in the device tree of the PLC Designer is updated to an older version or to one of the Lenze controllers 3200C, p500, c300 or p300.
Which products are affected?
PLC Designer from V3.20
Short-term measures:
Add the Profinet node after the update.

By updating a controller in PLC Designer to an older version or to another controller series, an existing Profinet node is deleted. This can be added again later.
