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).
