11.2.2. Object Description
This object defines a standardized way of reporting different types of measurement values (current, voltage,
power, energy etc.) from a measuring device.
Each instance, logical device, represents a group of measurement values for one separate measurement device.
Physically, measuring devices might be connected to a higher level network directly, or indirectly via a coupling
device. To enable host applications to implement either a direct or an indirect measuring device, the Anybus
CompactCom object model implies a 1:1 relationship between measuring device (a.k.a. logical device) and
instance number, where each instance attribute represent a group of measurement values (see list of instance
attributes below). The host application does not have to support all instance attributes listed.The command
Get_Attribute_Measurement_List is used towards the host application, to read out which measurement values
are supported by a device.
The table below shows an example of how the instances of the Anybus CompactCom object model maps to
PROFIenergy. PROFIenergy uses the Object number to address a logical device, while the Measurement ID refers
to the actual measurement value.
