Energy measurement
with ABB i-bus® KNX
ABB offers various solutions for decentral energy measurement on the basis of the KNX standard.
Variant 1
Electronic energy meters make the current energy values available on the
KNX bus system in conjunction with a KNX interface. The measured data
can be intermediately stored, evaluated and visualized from here.

Variant 2
The Energy Module can record the energy consumption for the individual
devices. It is used particularly when upgrading existing KNX systems and
wherever energy measurement is required without switch functions. It facilitates a detailed and transparent insight into the energy consumption of a
building.
The current meter values can be sent and evaluated.

ABB i-bus® KNX
Meter Interface Module ZS/S 1.1
Recording and processing of energy values and the current
meter readings is continuously gaining in importance. This is
not just because of the rising energy costs, but also because
of the frequently demanded evaluation and query options via a
distributed reading point.
Comfortable and economic solutions for modern energy
management can be realized with the Meter Interface Module
ZS/S 1.1.
Consumption and measured values of the electrical energy
consumption meters are recorded by the Meter Interface
Module ZS/S 1.1 and transferred via the ABB i-bus® KNX.
The device features an infra-red interface, which ABB energy
meters of types DELTAplus, DELTAsingle, ODIN, ODINsingle
or the new energy meters of the A-Series can be read.
The information and data, which is read, can be used, for
example, for cost centre accounting, energy optimization,
monitoring of installations and visualization.

ABB i-bus® KNX
Energy Module EM/S 3.16.1
The ABB i-bus® KNX Energy Module
EM/S 3.16.1 facilitates detailed analysis of energy consumption of electrical consumers in buildings, which are
controlled via KNX.
With the intelligent power grids of
tomorrow – the Smart Grids – electrical building installations will be facing
new challenges. In order to increase the
energy efficiency of buildings and at the
same time integrate the consumers in
the load compensation, it is necessary
to switch electrical devices in buildings
on and off based on external signals
such as time, consumption thresholds
or similar. The ABB i-bus® KNX provides
the optimum prerequisites for intelligent
buildings.
The Energy Module facilitates the
recording and analysis of active energy
consumption down to the consumer
level. When assigned to an energy
meter, the consumption values in an
electrical circuit can be evaluated in a
transparent fashion right down to the
device level. This detailed consumption
analysis allows for good evaluation of
the amortization periods for infrastructural measures or specific optimization
of the building control for increasing the
energy efficiency.

For each of the three channels, the active power, current and voltage as well
as further electrical variables (apparent power, crest factor, power factor
and frequency) can be measured. The
measured values are made available via
the KNX. They can be monitored with
threshold values. Should an overshoot
or undershoot of a defined threshold occur, a telegram can be sent on the bus,
and an assigned consumer, for example,
can be switched.

Energy Actuator SE/S 3.16.1
The ABB i-bus® KNX Energy Actuator
SE/S 3.16.1 is a Switch Actuator that
records the energy consumption of
the connected electrical loads in the
building.
The Energy Actuator determines the active energy consumption per switching
output. Furthermore, it provides the total
consumption of all three outputs. All
meter values can be sent cyclically, on
request or when a start or stop event
has occurred such as a time, operating
period or when a defined consumption
threshold is reached. Moreover, when a
stop event occurs the assigned output
can be switched off.
can be measured. The measured values
are made available via the KNX. They
can be monitored with threshold values.
Should an overshoot or undershoot of a
defined threshold occur, a warning can
be sent or a channel switched.
Application
Active consumption measurement
Monitoring of electrical values
Load management through load control
Switch Actuator, 3-fold
Benefits
The ETS application also enables a
simple load management functionality,
where up to ten Energy Actuators can
be interconnected. The electrical loads
connected to the three floating switch
outputs can be switched via KNX or
manually directly on the device.

Overview
Main and intermediate meters
For every channel, the active energy
consumption is measured continuously
by a meter (meter channel A...C).
The total consumption is determined by
the addition of the three channel-related
meter readings and also made available
(Meter total).
The special feature:
Every meter is assigned with an intermediate meter, which can be parameterized for individual measuring tasks.
Each of the four intermediate meters
can be started, stopped and reset via
the KNX bus.
The meter values can be sent cyclically,
on request or when a start of stop event
occurs.

The individual functions
Instrument and power values
The following values can be monitored
by threshold values with the Energy
Actuator and the Energy Module:
Instrument values
– Current value (per channel)
– Voltage (per channel)
– Frequency
Two thresholds are available for each
of these values. Warnings can be sent
or an additional switch reaction can be
parameterized on the Energy Actuator,
dependent on whether thresholds are
exceeded or the value falls below the
threshold.
Further values
(without threshold monitoring)
– Apparent power
– Crest factor (current)
– Power factor
These values can be sent or read via the
KNX bus.
Power values
– Active power (per channel)
– Active power total

The individual functions
Load control
With load control, an Energy Actuator
or an Energy Module can be parameterized as a master that can control up to
ten further Energy Actuators as slaves.
The master receives power values from
the slaves that are added internally to the
power total (sum of power values). If the
power total exceeds a parameterized
load limit, the master sends up to eight
load shedding stages on the bus. The
load limit can be modified via the bus,
e.g. in dependence on the time or the
currently valid power tariff.
With the slave devices, every output
Master
can be assigned with its own shedding
stage. If a slave receives the shedding
stage, it switches all outputs off with the
respective shedding stage. If the total
power still exceeds the load limit, after
a shedding stage has been switched
off, the master will then send the next
shedding stage, until the total power is
again below the allowed limit. After an
adjustable waiting time has passed, the
master will attempt to switch the shedding stages back on in reverse order.
