2.4.4 Data Representation (IO Data & Record Data)
As mentioned previously, the actual I/O configuration is determined by the IO Controller. The modules
are mapped to the input and output data areas in the order of their slot number.
Example:
In this example, the I/O Sizes for the ABC has been set to the following values:
IO Size In= 256 bytes (0x0100)
IO Size Out= 400 bytes (0x0200)
The following modules are specified in the IO Controller:
Resulting memory layout:
Note the “unused” part of the output data area.The reason for this is that only 272 bytes
(128+64+64+16) are actually used in the I/O module configuration, although IO Size Out is set
to 400 bytes.
