AM_Location
Asset management include two concepts of how to locate an asset; “Twelve level tree format” and “Slot- and Subslot number format”.
Location Concept: Slot- and Subslot Number
In case of a remote IO device the location of a component (e.g. rack module) is clearly defined by the slot of the IO device. Other components may span several slots, such as a backplane, or several subslots, such as a terminal block. This means each asset can be located by “BeginSlotNumber/BeginSubslotNumber” and “EndSlotNumber/EndSubslotNumber”.
For this concept the following parameters have to be considered:
Array index | Description |
|---|---|
0 | BeginSlotNumber |
1 | BeginSubslotNumber |
2 | EndSlotNumber |
3 | EndSubslotNumber |
Note
It is important that the defined slot-/subslot numbers (i.e. BeginSlotNumber, EndSlotNumber, BeginSubslotNumber and EndSubslotNumber) are present in the Real Identification. This is checked at conformance testing.
Location Concept: Twelve Level Tree Format
In case of a remote IO device the location of a component is clearly defined by the level information. The Twelve level tree format may be used for modular devices with hierarchical device structure. This means each asset can be located by a level number 0-11 (e.g. x.y.z level notation). If LT format is used a value must be provided at least for level 0. If a shorter array is supplied value 03FFh is implied for the missing levels.
For this concept the following parameters have to be considered:
Array index | Description | Value |
|---|---|---|
0 | Level 0 | 0000h - 03FEh: Address information to identify a reported node 03FFh: Level not used 0400h-0xFFFFh: Reserved |
1 | Level 1 | |
2 | Level 2 | |
3 | Level 3 | |
4 | Level 4 | |
5 | Level 5 | |
6 | Level 6 | |
7 | Level 7 | |
8 | Level 8 | |
9 | Level 9 | |
10 | Level 10 | |
11 | Level 11 |
