kW: Max Demand Total Real Power Max. Demand AI37 kW 0 331/332 This retains the largest value measured for Total Real Power
Demand (AI34) for any single demand interval since the
Max Demand was last explicitly reset via AV1 (this also
resets when the demand interval changes).
kVAR: Max Demand Total Reactive Power Max. Demand AI38 kVAR 0 333/334 This retains the largest value measured for Total Reactive
Power Demand (AI35) for any single demand interval since
the Max Demand was last explicitly
reset via AV1 (this also resets when the demand interval
changes).
kVA: Max Demand Total Apparent Power Max. Demand AI39 kVA 0 335/336 This retains the largest value measured for Total Apparent
Power Demand (AI36) for any single demand interval since
the Max Demand was last explicitly
reset via AV1 (this also resets when the demand interval
changes).
Pulse Counter 1 (Real
Energy)
Pulse Counter 1 (Real Energy) AI40 n/a 0 337/338 Contact closure counter for Real Energy pulse output. Check
Pulse setup on the LCD display for the weight of each pulse
output count. These values are derived from 32 bit integer
counter and roll over to 0 when the integer counters do.
Write 16498 (0x4072) to the Present_Value property of
Analog_Value object AV1 to reset both Pulse Counters to 0.
Pulse Counter 2 Pulse Counter 2 AI41 n/a 0 339/340 Contact closure counter for Reactive Energy pulse output.
Check Pulse setup on the LCD display for the weight of each
pulse output count. These values are derived from 32 bit
integer counter and roll over to 0 when the integer counters
do. Write 16498 (0x4072) to the Present_Value property of
Analog_Value object AV1 to reset both Pulse Counters to 0.

AV1 n/a 0 129 Reset (aka Command Register):
- Write 30078 (0x757E) to clear all Energy Accumulators to
0 (All).
- Write 21211 (0x52DB) to begin new Demand Sub-Interval
calculation cycle. Takes effect at the end of the next 1
second calculation cycle. Write no more frequently than
every 10 seconds.
- 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 Counts to zero.
- Read always returns 0.
