Hi everyone,
I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager".

Here is the code of my POU in the library:

FUNCTION_BLOCK POU
VAR
    eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE;
END_VAR

Attached is the error that I get.
I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again.
Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?
