Assigning a name to a PROFINET IO device online
The devices on your PROFINET network must have an assigned name before you can
connect with the CPU. Use the "Devices & networks" editor to assign names to your
PROFINET devices if the devices have not already been assigned a name or if the name of
the device is to be changed.
For each PROFINET IO device, you must assign the same name to that device in both the
STEP 7 project and, using the "Online & diagnostics" tool, to the PROFINET IO device
configuration memory (for example, an ET200 S interface module configuration memory). If
a name is missing or does not match in either location, the PROFINET IO data exchange
mode will not run.
