FB5: GETGUD - read GUD variable

Function
The function block FB5 "GETGUD" is used for reading global user data (GUD) in the NC or
channel area.
In order to reference the NC variables, they are first selected with the "NC VAR selector" tool
and generated as STL source in a data block. A name must then be assigned to this data block
in the S7 symbol table. When calling FB2, the variable addresses are transferred in the
following form: Parameter "Addr1" to "Addr8" = "<DB name>".<S7 name>"
Request for reading NC variables
Call of FB5 with positive edge change, parameter "Req" = 0 → 1
Parameter "Addr": The pointer to the name of the GUD variables, symbolically with "<Data
block>".<Variable name>
