Analog Input (AI) Objects
Use the Present_Value property of the Analog_Input objects for all read-only numeric variables in
the meter other than those used specifically for device configuration (in the Device Object). .
These objects support the Description and Reliability object properties and all required Analog_
Input object properties. None of them are writable. The values that are not instantaneous (i.e.,
Accumulated Energy, Max Demand, Pulse Input Counts) are non-volatile. They are not updated
while control power is inactive, but their past values are retained when power is restored. The
Present_Value of the accumulated data objects (AI1, AI26-AI27 and AI42-AI44) use floating-point
