The symbol table 17 defines interface signals to/from the HMI.
The symbol table 18 defines the interface signals from the NCK channel, including the auxiliary functions, D functions, H
function, etc.
The symbol table 19 defines the interface signals to/from the NCK.
The symbol table 20 defines the interface signals to/from the channel.
Symbol table 21, 22, 23, 24, 25: IS_AX1, IS_AX2, IS_AX3, IS_AX4, IS_AX5
These five symbol tables define the interface signals to/from the axes.
Symbol table 26: IS_AX_P1
The symbol table 26 defines the interface signals to/from the PLC axis.
The symbol table 27 defines the PLC machine data from the NCK.
The symbol table 28 defines each bit of a PLC user alarm (V1600 000x).
The symbol table 29 defines all the user data (128 byte, retentive) used in the standard subroutines.
The symbol table 30 defines the seven special memories of the SINUMERIK 808D ADVANCED (SM0.0 to SM0.6).
The symbol table 31 defines the memories used in the standard subroutines. These memories can be used as the global
variables.
