Which PROFINET nodes support the extended PROFINET diagnostics and what do you have to configure?

  • Entry
  • Associated product(s)
With the extended PROFINET diagnostics it is possible to have functions like the diagnostics and parameterization of integrated Ethernet interfaces (fiber-optic diagnostics and topology configuration, for example).

The PROFINET IO devices that support extended PROFINET diagnostics are configured in the STEP 7 Hardware Configuration. They are available in the hardware catalog and have additional ports or interface modules as subslots in the module's slot. 

More information about PROFINET diagnostics and how to implement the PROFINET device module in SIMATIC is available in the manual "SIMATIC PROFINET with STEP 7 V16" in Entry ID 49948856

The PROFINET IO devices that support the extended PROFINET diagnostics can only be operated on PROFINET IO controllers that likewise support the extended PROFINET diagnostics.

There is a migration GSDML file for some of the PROFINET IO devices listed above for operating the PROFINET IO device on a PROFINET IO controller that does not yet support the extended PROFINET diagnostics.
