*)
The number of operable PROFINET IO devices can be reduced if the devices being used require extensive configura-
tion data due to large numbers of submodules. In this case, the memory on the CP will not be adequate and you will re-
ceive a message in the diagnostics buffer about lack of resources when downloading the configuration data.
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 diagnostics buffer of the CPU.
These I/O access errors occur during operation only in the "consistent user data" mode and
with a low OB1 cycle time.
2.6 Characteristic data for PROFINET CBA
Note
PROFINET CBA versus security function
If you use PROFINET CBA, you cannot enable the CP for the "Security" functionality.
2.6.1 Typical values and limit values
The CP supports PROFINET CBA interconnections between PROFINET CBA components.
The "typical" values specified below are values that cause the SIMATIC iMap configuration
tool to generate a warning if they are exceeded. The system may nevertheless be operable.
