Analog_Value Objects

Use the Present_Value property of the Analog_Value object for all writable variables in the meter other than those used specifically for BACnet configuration, Time
Synchronization (in the Device Object), or data logging (in the Trend_Log objects).

Values are checked when written, and errors are returned for invalid entries. This table describes how the meter uses those variables, what values are valid, and what their
defaults are. When writing values to the Present_Value properties of Analog_Value BACnet objects, there is a delay of up to about two seconds to validate and store the new
value. An immediate read of the same property before that delay has elapsed can return the prior value (even if the new value was accepted). To read a value immediately after
writing it, check the Reliability property first. When it reports a No_Fault_Detected status, the Present_Value of the object is current.

These objects support the Description and Reliability object properties and all required Analog_Value object properties, but Present_Value is the only writable property.

Command Register:
- Write 30078 (0x757E) to clear all energy accumulators to 0 (All).
- Write 21211 (0x52DB) to begin new Demand Sub-Interval calculation cycle and log

another data value on Trend_Log objects TL1-TL3 (when the meter is in Manual “Sync-

to Comms” mode). This takes effect at the end of the next 1 second calculation cycle.

Write no more frequently than every 10 seconds. Trend_Log values are only present on

the E50H5A model.

- Write 21212 (0x52DC) to reset Max Demand values to Present Demand Values. Takes

effect at the end of the next 1 second calculation cycle. Write no more frequently than

every 10 seconds.

- Write 16498 (0x4072) to clear pulse counters to 0.
