Configuration steps
To be able to read a GUD variable, its name must be stored in a string variable. The data block
with this string variable must be defined in the symbol table so that the "Addr" parameter can
be assigned symbolically for FB GETGUD. A structure variable can be defined optionally in
any data area of the PLC to receive the variable pointer (see specification in following example).
