Resetting Modbus Registers
™
Most of the PowerScout
registers are real-time values such as instantaneous watts or power factor. However,
some registers are accumulated values such as kWh, kVARh, kVAh and various Peak Demand (kW) values. To
reset the accumulating registers use the standard Modbus protocol to write a "0" to register 40001.
