Structure of asset management blocks
Each AssetManagementBlock contains identification data and localization information for an
asset. An AssetManagementBlock has a substructure with basic characteristics described
below.
The header of an AssetManagementBlocks contains the coded information about which of
the three possible AM data compilations the record contains. Devices make a suitable
BlockType available in accordance with the various device types:
● Complex devices with information about the hardware and firmware (BlockType
"AM_FullInformation")
● Complex devices with information about the hardware (BlockType
"AM_HardwareOnlyInformation")
● Devices with information about the firmware (BlockType "AM_FirmwareOnlyInformation")
The differentiation provides an efficient data structure below the header. Nevertheless, the
data record can have a considerable size (maximum of 64 KB, depending on the number of
assets that the IO device supplies).
