All object instances of the base information model represent the online view on the PROFINET network.

All PROFINET objects modeled in this specification are only created in the address space when the OPC UA Server detects their PROFINET counterpart. The objects are removed from the address space when the OPC UA Server detects their absence in the PROFINET network or PROFINET device.

The chapter 6.10 of [PN TAD] describes the possible ways of implementing the PROFINET device discovery. The chapter 11.3 of [PN TAD] describes the detection of the real modules and real submodules of a device and how to get their identification and asset data.

All these ContainerType objects only exist if objects are available in the container.
