6.2 PROFINET IO and PROFINET CBA
PROFINET variations
There are two varieties of PROFINET
● PROFINET IO: IO devices are connected to an S7-400 CPU (IO controller) via Ethernet.
● PROFINET CBA: A component-based automation solution in which full technological
modules are used as standardized components into large plants. You create the CBA
components in SIMATIC with STEP 7 and the SIMATIC iMap add-on package. You
connect the individual components with SIMATIC iMap.
When you download CBA interconnections to an S7-400 CPU, they are stored in the
working memory. The interconnections are lost if there is a defective hardware, a memory
reset or firmware update.
If you use Profinet CBA, you cannot use isochronous mode or perform configuration
changes in runtime (CiR).
PROFINET IO and PROFINET CBA
PROFINET IO and PROFINET CBA are two different views of automation devices on
Industrial Ethernet.
