RESETTING BACNET OBJECTS/MODBUS REGISTERS
Many of the Power Patrol registers are real-time values such as instantaneous watts or power factor.
However, some objects are accumulated values such as kWh, kVARh, kVAh and various Peak Demand
(kW) values.
To reset all BACnet accumulated objects at once:
 Write to object identifier 10140 “Clear Accumulated Values” current value 1234.0.
To reset all Modbus accumulated registers at once:
 Write to register 44066 “Clear Accumulated Measurements” current value 1234.
In HeadStart, accumulating registers can be reset using the Read/Write tab.
 Click Clear Totals at the bottom of the screen.
See the tables in the Appendices for a list all of the objects/registers available on the Power Patrol
meters.
SYNC REGISTERS
To freeze register readings, press Sync Registers. This will prevent any register from being update in
HeadStart until the Sync Registers button is pushed again.
