Step 3 – Hardware configuration of the S7 PLC: Configuration
For the configuration of the PROFINET-IO system using the HW Config of the SIMATIC
Manager, insert the MA 248
i
into your project. An IP address is now assigned to a unique
"device name".

Step 4 – Configuration of the modules
Now select a corresponding data module for the input and output area.
A number of combinable modules are available with various data lengths (4, 8, 12, 16, 20,
32 … 1024 bytes). In total, a maximum of 1024 bytes are possible for both the input bytes
and for the output bytes.
Notice!
Because the data module contains 2 bytes for the control and status bytes, the actual user
data length is always 2 bytes smaller than the selected data module.
E.g., when using the data module with 12 bytes, there are effectively 10 bytes available for
user data on the Leuze device after subtracting the 2 bytes for status and control bytes.
Recommendation
In most cases, the 4-byte module is sufficient for the output module.
