Mapping

Table 3-6
With the parameter "IEC 103 Settings - Counters" (see chapter 3.3.1) the user can
select, whether the energy values (table 3-6) will be transferred.
3.3.2.1

Energy Counters from Binary Inputs

Energy Counter 1 and Energy Counter 2 count energy pulses from binary inputs via
binary input module.
For conversion of the transmitted pulses to an energy value, a factor "Energy increase
per pulse" has to be defined during parameterization of the binary input (ref. to the
SIMEAS P 7KG7750/55 Device Manual).
3.3.2.2

Energy Counters Calculated from Measurement Values

The required conversion factor for the calculation is 1837.
The following formula applies to the calculation of the energy:
