Response of the new version:
The symbol file is also created correctly if variables from nested function blocks or structures were selected in the 'Symbol Configuration'.
The symbol file generated by the PLC Designer does not contain any entries.
The PLC variables of the Lenze controller cannot be accessed externally.
When does the behaviour occur?
In order to be able to access PLC variables externally, e.g. with an OPC server, the PLC Designer generates a symbol file. With the help of the 'Symbol Configuration' object in the device tree of the PLC Designer, you can configure for which PLC variables entries (symbols) are created in the symbol file when compiling the project. If variables from nested function blocks or structures are selected in the 'Symbol Configuration', then it can occur that the PLC Designer creates a symbol file without entries (symbols) when compiling.
Which products are affected:
Short-term measures:
After compiling the PLC project, check whether all ticks for variable selection are set in the 'Symbol Configuration' as previously configured. Correct the configuration if necessary.
Do not select PLC variables from nested function blocks or structures in the 'Symbol Configuration'.
Evaluation / recommendations:
Due to the function restriction, the symbol file required for external access to PLC variables is not generated correctly by the PLC Designer. Observe the notes from 'Short-term measures'.
