much energy was consumed in the last 3 minutes. In order to display the power consumption in kW/h, we have to
extrapolate the power consumption to one hour (60 minutes / 3 minutes = factor 20).
We calculate the delta for the current number of pulses from the last and current meter values that we read from
the S0 meter. With a delta of 25 pulses, these correspond to a power consumption of 25 watts in the last 3
minutes.
In 60 minutes, with constant power consumption, there is a consumption of: 25 x 20 = 500W/h
 0,5KW/h Power consumption
Calculation
The evaluation cycle of the S0 pulses is 3 minutes.
Factor = 60 minutes / 3 minutes Evaluation cycle
Delta pulses = new pulses - old pulses
Power consumption (KW/h) = (delta * factor) / 1000

Data output 1-Wire Controller / 1-Wire Gateway
For the Dual S0 counter module the following data of the 32Bit counter values are output.
The 1-Wire interface of the Dual S0 counter module is controlled by standard commands for the DS2423 block
and the data is read out.
The power of electricity meters, gas or water consumption can be calculated using the continuous meter values
output. A wind sensor can also be evaluated.
Data output:
The data output for the Dual Counter is in the following data format.
1_OWD1_1|Counter value A => Controller no._One Module no._Data set|Counter value 32Bit
1_OWD1_2|Counter value B => Controller no._One Block no._Data set|Counter value 32Bit
Further information on the possibilities and commands can be found in the current documentation 1-Wire
Controller /1-Wire Gateway.
