PROFINET Data Exchange
6.3

Data Representation (IO Data and Record Data)

The actual I/O configuration is determined by the PROFINET IO Controller. The modules are
mapped to the Input and Output Buffers in the order of their slot number.
Example:
In this example, the data sizes have been set to the following values:
Input I/O Data Size:
Input Parameter Data Size:
Output I/O Data Size:
Output Parameter Data Size:
The following modules are specified in the IO Controller:
Slot
0
1
2
Offset
0x000
0x0CF
0x0D0
0x1FF
