Overview
● PLC Programming Tool
Structure of the symbol tables
The PLC subroutine library has been designed with symbol addressing method, which helps
you easily understand the PLC programs. All the addresses in the subroutine library use
symbols for programming. All the interface signals are named with symbols and assigned to
different symbol tables.
