7.3.5 Data Exchange between PLC Function (CPU) and I/O
Modules
The PLC function (CPU) of the PFC uses direct addresses to access the I/O
module data.
The PFC uses absolute addresses to reference the input data. The data can then
be processed internally in the controller using the IEC-61131-3 program.
Flags are stored in a non-volatile memory area in this process. The results of
linking can then be written directly to the output data employing absolute
addressing.
