    How can I make symbols in Global Variable?

    I am able to create "SYM_XML" file with the main project file
    (CoDeSys V2.3.9.13 and select PLC model Wago 750-841(FW12...))

    I just need to create some symbols in "SYM_XML" file.
    But I am a beginner of using CoDeSys and struggling to understand the software.

    If you someone have a sample program or sample "SYM_XML" with BOOL, INT, DINT or something,
    would you mind to share?

    I'm not sure what you mean by symbols. If by symbols you mean variables to use in your program, the syntaxes are as follows:

    VAR_GLOBAL

    MyVar_Bool :BOOL;
MyVar_Byte:BYTE;
MyVar_Word:WORD;
MyVar_DWord:DWORD;
MyVar_DInt:DINT;

MyMem_Bool     AT %MX0.0 : BOOL;
MyMem_Byte     AT %MB0    : BYTE;
MyMem_Word        AT %MW0   : WORD;
MyMem_DWord      AT %MD0    : DWORD;
MyMem_DInt     AT %MD1    : DINT;

    END_VAR
