Issue:
Viewing variable comment from EcoStruxure OPCUA server Expert


Product Line:
EcoStruxure OPCUA server Expert


Resolution:
The variable comments can be accessed by the OPCUA client if the OPCUA server Expert is configured to use the symbol table file(.XVM). The PLC variable comment is included in the XVM database file. However when using data dictionary, all symbolized variables with their characteristics except variable comments, of the application are embedded in the PLC memory.  Since the variable comments are not stored in the PLC memory, if the OPCUA  Server Expert is configured to use Data dictionary, it would not be possible for the UA client to access it.
