Resetting BACnet Objects/Modbus Registers

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 ViewPoint, accumulating objects/registers can be reset using the Read/Set or
Read/Write tab.
● Click Clear Totals at the bottom of the screen.
