    Hi forum,

    there is a way to obtain the string of enum variables?

    example:

    I have this enum:

    TYPE PLC_LOG_DEVICE :
(
   NONE := 0,
   
   MANDREL  := 1,
   CLAMP   := 2,
   STORE   := 3,
   
   
   LAST_DEVICE
);
END_TYPE

    How can I assign to a string the value "MANDREL", "CLAMP", etc. based on enum value?

    I tried to search something about and I found this https://forum.codesys.com/viewtopic.php?f=11&t=5955 but I cannot start the project, it cannot find the "sys shm library" and I don't understand how to solve this.

    In SP11 or higher:

    {attribute 'to_string'}
TYPE PLC_LOG_DEVICE :
(
   NONE := 0,
   
   MANDREL  := 1,
   CLAMP   := 2,
   STORE   := 3,
   
   
   LAST_DEVICE
);
END_TYPE

    sVar: STRING;
eVar: PLC_LOG_DEVICE;
sVar := TO_STRING(eVar);

    sVar: STRING;
eVar: PLC_LOG_DEVICE;
sVar := TO_STRING(eVar);

    THANKS A LOT
