AM1 |
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. |
|
AM2 |
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. |
|
AM3 |
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. |

AM7 |
Asset localization changed |
The physical location of an asset was changed. E.g. moved from one machine to another. |

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. |
|
AM10 |
Asset location changed |
The asset is moved to a different place in the asset hierarchy. |
|
AM11 |
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. |
|
AM12 |
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:
|
|
AM13 |
