With the device description for the current controller firmware versions the library IoDrvCIFXProfinetDevice2 is always used with version V3.5.7.31. When updating a project there is no indication that a newer library version is available.
What happens?
In the Lenze controller the exception error 'Access violation' occurs.
Error messages occur during project download.
When does the behaviour occur?
The behavior described above can occur if the controller is updated to a newer firmware version in an existing PLC Designer project and a Profinet-IO device (MC-PND) is configured for the controller in the project.
Which products are affected? Controller 3200C
Panel controller p500
Controller c300
PLC Designer
Short-term measures:
Make sure that the library IoDrvCIFXProfinetDevice2 in the library manager is set to version V3.5.7.31. If necessary, change this via the placeholder setting.
Evaluation/Recommendations:
Updating a controller in a PLC project can lead to an exception error in the controller after the project download if a Profinet-IO device card is used in the controller. An applicative solution is described under Short-term measures.
