Corrected from:
PLC Designer V3.12
Response of the new version: The mapping of a CANopen slave will not change when changing the settings of the CANopen slave.
What happens:
Input and output channels of a CANopen slave with the data type LWORD change their data type to LINT. The variables mapped to these channels are deleted from the CANopen I/O mapping. This leads to compilation errors when the PLC project is compiled.
When does this behaviour occur?
The above-described behaviour occurs if the settings of a CANopen slave with input or output channels of the data type LWORD are changed on the tabs (e.g. setting the checkbox "Optional device").
Which products are affected?
PLC Designer V3.6 and higher
Short-term measures:
After changing the settings of a CANopen slave, check the PDO mapping in the "CANopen I/O mapping" tab and correct it, if necessary.
Evaluation/recommendations:
When changing the settings of a CANopen slave, in the case of input/output channels with the data type LWORD, the mapped variables are deleted from the I/O mapping and the data type is changed. This leads to compilation errors due to which it is no longer possible to transfer the project to the Lenze controller. The device descriptions for Lenze devices supplied with the PLC Designer do not support the data type LWORD. When these device descriptions are used, the function restriction does not occur.
