Corrected from:
PLC Designer V3.22
Response of the new version:
If PDO 16#1400: Receive PDO1 Communication Parameter is deleted from the device 'Lenze Generic Drive' V1.0.0.4 and added again, the PDO contains 4 objects of 16 bits each. Older versions of the device 'Lenze Generic Drive' still have 3 objects a 16Bit, as described below.
Already from PLC Designer V3.18: The 'Lenze Generic Drive' can be used on the CANopen Manager MC-CAN2 without triggering the below-described exception.
What happens?
The PLC Designer displays an exception:
Unhandled exception has occurred in your application.
Object reference not set to an instance of an object.
When does this behaviour occur?
An exception occurs if the 'Lenze Generic Drive' is added to the CANopen Manager MC-CAN2 and the communication settings of the 16#1400: Receive PDO1 Communication Parameter are edited in its 'PDO' tab.
If the 16#1400: Receive PDO1 Communication Parameter PDO is deleted and newly added, the communication settings can be edited, but the PDO then only contains 3 16-bit objects instead of 4 objects.
Which products are affected?
PLC Designer from V3.14
Short-term measures:
None
Evaluation/recommendations:
If the CANopen device 'Lenze Generic Drive' is used in a PLC project, you cannot change the communication settings of the Receive PDO1. All other PDOs of the device are not affected by this function restriction.
