What happens?
The CAN bus of the Lenze Cabinet Controller c300 or on the Lenze Panel Controller p300 does not become operational.
When does the behaviour occur?
The behavior occurs when a controller 3200C or p500 with a CAN bus on Sub-D connector 'CAN2' was configured in a project and this controller was subsequently updated in the device tree to a c300 or p300.
Which products are affected?
PLC Designer from V3.8
Short-term measures:
Set the Sub-D connection 'CAN1' in the object 'CANbus' already in the original project, i.e. before updating the project to a c300 or p300.
Alternatively, you can delete the 'CANbus' object in the device tree of the c300/p300 and add it again.
Evaluation/Recommendations:
The function restriction can only occur if the controller is updated from a 3200C/p500 to a c300/p300 in the PLC Designer project. Under 'Short-term measures' applicative solutions are described.
