Characteristic Data for PROFINET IO

The CP supports the following maximum configuration as a PROFINET IO
controller:
Table 5-5
Number of possible PROFINET IO devices
Size the input area over all PROFINET IO devices
Size the output area over all PROFINET IO devices
Size of the IO data area per submodule of a module in an IO device
S
Inputs
S
Outputs
Size of the consistency area for a submodule
Data record length
Supported data record numbers
Note
Note the following for PROFINET IO: If you use modules with >=32 bytes of
input/output data, this can lead to I/O access errors; access errors are entered in
the diagnostic buffer of the CPU.
These I/O errors occur during operation only in the "consistent user data" mode
and at a low OB1 cycle time.
Notice
In PROFINET IO, the number of possible slots is limited.
As of STEP 7 V5.3.2, the slot boundary is checked!
The maximum number of slots depends on the CPU being used:
CPU417*: 2173 slots
CPU416*: 2173 slots
CPU414*: 1632 slots
CPU412*: 1088 slots
