Structure of symbol tables
All the addresses in the PLC subroutine library are programmed with symbols. All the signals of interfaces are named by
symbols and arranged in different symbol tables.
The name of a symbol follows some conventions. For details, see Section "Conventions for the symbols used in the
subroutines (Page 143)".
