Using the CP 1616 as PROFINET IO Controller and Device
You can also use the CP 1616 as a controller and device at the same time. In other
words, the same CP 1616 has the function of a controller and a device.
When configuring in STEP 7, there is one feature you must bear in mind:
A separate network must be configured for each mode because the same IP
address cannot be used twice in the same network. Physically, these can be
different networks or the same network.
The following figure shows such a configuration.
