Characteristic Data for PROFINET CBA

5.6.1

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; it is nevertheless
possible that the configuration can be operated.
If one of the limit values specified for the interconnections is exceeded, they
cannot be downloaded to the module. When the interconnections are downloaded,
the SIMATIC iMap configuration tool generates an error message to this effect. If a
limit value relating to the number or size of components is exceeded, the CPU will
not change to RUN!
