Applications
Display Elements
The LON add-on component is used for scanning measuring
points within the energy control system in a decentralized fashion.
The U1660 meter reading module processes data from up to 8
energy meters with pulse output (S0), or floating contact. The
active inputs do not require any additional power supply which
minimizes wiring expenses.
The add-on component expands the functions offered by the
U1601 summator, the U1602 micro-summator and the U1603
mini-summator to include external inputs via the LON interface.

Function
U1660 is a meter reading module with eight active inputs. It
determines energy and instantaneous power on the basis of SO
pulses.
The valence of a pulse (delta) is calculated from the meter con-
stant (nciPulseRate). The pulses are counted (nvoEnergyPower)
and converted into energy (nvoEnergy). Instantaneous power
(nvoPower) is calculated from the distance between two pulses.
The network variables nvoEnergyPower, nvoEnergy and
nvoPower are calculated and transmitted after each pulse. The
meter readings (nvoEnergyPower, nvoEnergy) are lost upon auxil-
iary voltage failure.
In addition to energy and power measurement, the state of the
binary inputs is transferred to the network (nvoInputState[8],
nvoAllInState).

Inputs
8 ea. S0 pulse
per DIN 43864
The active inputs supply the power
required for operation. The + terminals
of the SO inputs S01+ ... S08+ are con-
nected with each other.
Additional Information:
• nvoAllInState supplies the state of all 8 S0 inputs. This has no
effect on the energy and power measuring functions. Each
input is equivalent to one bit:

Example: nvoAllInState = 3
means: input 1 and input 2 are ON (current flow), all other
inputs are OFF.
• Owing to the operating system of the neuron chip, the power
values of small pulse distances are subject to heavy scatter-
ing.
• Use of U1660 without summator:
The energy of the network variable nvoEnergy is calculated by
means of float arithmetics with simple accuracy.
The resolution of the float numbers decreases with increasing
value.
The greater the value, the greater the error resulting from the
addition of an energy delta. The evaluating application must
take this feature into account and ensure that the meter read-
ings are deleted (nviEnergyClear).
Alternatively, the network variable nvoEnergyPower (number
of pulses) can be used. It is not an SNVT.
Example:
Value
Resolution
1 0,00000012
8 0,00000095
128 0,000015
2.048 0,00024
32.768 0,0039
524.288 0,063
8.388.608 1,00
• Use of U1660 with the U1601, U1602 or U1603 summators:
The float arithmetic problems do not arise here because the
number of pulses is transmitted as integer number
(nvoEnergyPower).
