The following end customer requirements are relevant for asset management. A more detailed description of these use cases can be found in [PN TAD].

The requirements are written from the perspective of an asset management tool user.

Table 8 – Asset Management User Requirements





Unique Identification

The asset must have a unique Identification in the namespace of all installed assets independent whether the asset is installed in a cell or a machine.


Hardware and Firmware version management

Hardware and Firmware versions of the installed equipment should be discovered or compared with possible white-lists or black-lists.


Application version management

The application programs running on PLCs, robots or drives are also versioned and part of the asset management. Versioning for these applications shall be visible. This requirement can be solved in a comparable way then firmware version management.


Asset changed

End users want to know, if an asset is changed.


Asset installed

A new asset is installed in the cell or machine.


Asset removed

A new asset is removed from the cell or machine.


Asset localization changed

The physical location of an asset was changed. E.g. moved from one machine to another.


Machine part discovery

Usually the assets installed in a machine are in the responsibility of the machine builder. If some of these assets are replaced by the operator of a machine, the asset discovery of integrated assets is required.


PROFIsafe Device parameters changed

The OEM wants to know, if PROFIsafe Device parameters are changed by an external engineering tool in the device and/or in the engineering system of the IO controller for startup parameters.


Asset location changed

The asset is moved to a different place in the asset hierarchy.


I&M Write

The OEM wants to set writeable I&M1...3 parameters via OPC UA independent from the configuration in the engineering system of the IO controller.


Network parameter check

The end user wants to know, if all installed PROFINET devices follow specific rules for their network parameters given by the OEM. Network parameters are:

  • PROFINET Name of Station
  • IP-Address
  • Subnet mask
  • Default gateway
  • Allowed cycle times
  • Allowed data hold times


Docking Devices

PROFINET devices which are connected and disconnected to the network at runtime in normal operation.
