● A symbol consists of a maximum of 11 upper case characters and numbers (including the leading character). Except for
underlines, you cannot use any other special symbols like =, +, -, [ ], etc.
Symbol tables 1 to 2
The symbol tables 1 to 2 are for the manufacturer-defined SINUMERIK 808D I/O. Here you can define input/output tables for
your machines.
Symbol tables 3 to 5, 7 to 13
These ten symbol tables are reserved for the subroutines.
Note
Important!
If the colour of a
symbol is displayed in red, this indicates that the naming does not follow the rules of the PLC Programming
Tool. In this case, you must check:
● whether the name uses special symbols like =, +, -, [ ], etc..
● whether the leading character is a number.
If there is a red wave under a symbol name or address, it indicates that you have used the same symbol name or address
for another symbol (there is also a red wave under its name or address). In this case, you must check the repeated name or
address and change it.
Symbol table 6: MANMACH
This symbol table is for the function of a manual machine.
Symbol table 14: ASUP
This symbol table is for the ASUP function. It defines the start, operating results and other properties of the ASUP function.
Symbol table 15: PLC_sle_PP
This symbol table is for the PLC to select part programs. It defines the interface signals for the PLC to select part programs.
Symbol table 16: IS_MCP
This symbol table is for the manufacturer-defined MCP interface signals. With this symbol table you can define the MCP
signal tables for your machines.
Within the PLC subroutine library and all the subroutines, all the MCP-related signals are defined in this symbol table.
An MCP signal is transferred to the interface area via a subroutine. For the SINUMERIK 808D MCP, you can use subroutine
37 to transfer the MCP input/output signals to the interface area. For your own MCP, you just need to create a subroutine to
realize the transfer, and the other subroutines are still available.
