44062 4061 Time Since Reset LSW Seconds since KWH register was reset. LSW
44063 4062 Time Since Reset HSW Seconds since KWH register was reset. MSW
44064 4063 Data Tick Counter Internal sample count (gets cleared every minute): may
be used to determine if sample read is a newer sample
than last read.
44080 4079 kW System Average Equals KWH_SYSTEM_L&M ÷ (TimeSinceReset_L&M
seconds /3600 seconds/Hr) (resettable).
44081 4080 kW Demand System Min System Minimum Demand (kW)
44082 4081 kVA Demand System Max System Maximum Instantaneous kVA Demand (kVA,
resettable). It displays the default value after a CAM
until one demand window elapses. After a power cycle
or CPU reset, the value is not reset and does not
update again until one demand window elapses.
44083 4082 kVA Demand System Now System Average kVA Demand For the most recent
(current) Demand Window (resettable). Displays the
default value after a CAM or reset, or power cycle.
Updates every minute thereafter. True demand value
takes a demand period to get to actual value. Similar to
44005.
44084 4083 kVAR Demand System
Max
System Maximum kVAR Demand (kVAR, resettable). It
displays the default value after a CAM until one
demand window elapses. After a power cycle or CPU
reset, the value is not reset and does not update again
until one demand window elapses.
