5.3.2.4 End User Requirements

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
IDNameDetails
AM1Unique IdentificationThe 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.
AM2Hardware and Firmware version managementHardware and Firmware versions of the installed equipment should be discovered or compared with possible white-lists or black-lists.
AM3Application version managementThe 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.
AM4Asset changedEnd users want to know, if an asset is changed.
AM5Asset installedA new asset is installed in the cell or machine.
AM6Asset removedA new asset is removed from the cell or machine.
AM7Asset localization changedThe physical location of an asset was changed. E.g. moved from one machine to another.
AM8Machine part discoveryUsually 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.
AM9PROFIsafe Device parameters changedThe 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.
AM10Asset location changedThe asset is moved to a different place in the asset hierarchy.
AM11I&M WriteThe OEM wants to set writeable I&M1...3 parameters via OPC UA independent from the configuration in the engineering system of the IO controller.
AM12Network 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

AM13Docking DevicesPROFINET devices which are connected and disconnected to the network at runtime in normal operation.
