Sensor bar
Currents in AC power systems can be measured with the sensor bar. The measured data
are forwarded to the Data Manager via the RS485 bus and evaluated. The Data Manager
also supplies the 9 V to the sensor bar.
The sensor bar is offered in four variants, with three, six, nine or twelve slots respectively for
the current sensors. The current sensors are located directly on the miniature circuit
breakers and they register the latest current values. The conductors to be measured are run
through the ring-shaped opening in the current sensors to the connections of the miniature
circuit breaker. Up to eight sensor bars can be connected to one Data Manager. With the
sensor bar with twelve current sensors, the currents of up to 96 conductors can be measured
and transferred to the Data Manager. Every sensor bar has a unique Modbus address in the
range between 1 and 247.

3.5 System environment
The Data Manager is installed in the fuse cabinet where it is connected after the main fuse in
the subdistribution board. The device must be connected to all three phases of the power
system at the time of installation so that the overall energy consumption can be correctly
measured.
The sensor bar is connected via RS485. The sensor bar and the connected sensors are
located on the individual fuses in the fuse cabinet. Up to 8 sensor bars with 12 sensors each
can be connected, giving a total of 96 sensors in the maximum configuration. The length of
cable between the Data Manager and a maximum of 8 sensor bars must not exceed 10
meters.
The Data Manager is connected by LAN (if necessary via an additional router) to the PC
running the Siemens-specific Sentron software.
In communication via LAN, the Data Manager is the Modbus / TCP slave, while the PC with
the Sentron software is the Modbus / TCP master. The data are sent continuously to the
higher-level management system while a connection is present.
Note
A continuous data connection to the Sentron software is required. If the data connection is
interrupted, no data are buffered on the Data Manager.
In communication via RS485, the product is the Modbus / RTU master, and the connected
sensor bars are the Modbus slaves.

The Data Manager has a 63 A direct connection. For applications with other requirements,
external current transformers can be additionally connected to the Data Manager.
The corresponding transformer ratio can be set in the web browser so that the accuracy is
not impaired.
When using external current transformers, the respective measuring accuracy must be taken
into account. The Data Manager displays the current values extremely precisely at a current
transformer ratio of 600:5.
Connections
Above, you will find the connections L1, L2, L3; below also, plus an additional connection for
N. In the middle, you will find the connection for the LAN cable. The connection for the
RS485 connector is at the top of the Data Manager.
Note: if the communication cable is incorrectly connected, the Data Manager switches to a
protection mode and does not perform any measurements. To trigger a reset, you must
briefly disconnect the Data Manager from the auxiliary power.

Sensor settings
In the Sensor settings, you can search for sensor bars connected to the Data Manager by
clicking the button "Rescan sensor bus".
As soon as the sensor bars are detected, they appear in the left-hand column.
The number of sensor bars is detected automatically. The sensors can be assigned
individual names, and they must be assigned to individual phases. In special applications,
the power factor can also be defined manually. If a sensor is not connected, there is also no
need for any phase assignment.
An eye symbol on the far right shows which sensors are to be compared with each other
statistically. This can be adapted individually. Up to eight sensors can be compared with
each other, regardless of whether they are located on the same sensor bar or not. The
sensors that are to be compared with each other need only be connected to the same Data
Manager.

Current values
Under "Current values", the following live values of the sensors can be read out:
● Current
● Voltage
● Power factors of the different phases
● Current values of the individual sensors
"0" values against a red background indicate sensors through which no power is currently
flowing. "-" values with a red background indicate sensors for which no phase assignment
has been carried out. In this way, it is immediately apparent if there is a fault, or if the
sensors are not active. This view hugely reduces the search effort for errors, especially with
up to 96 connected sensors.

5.1.8.4 Network Settings
In the Network Settings, a static IP address can be assigned manually. The Data Manager is
supplied with a fixed IP address (192.168.1.200).
The Data Manager can also be assigned an individual name here. In the Timeserver
settings, you can determine whether the Data Manager obtains the time automatically from
the network via the server. This is only possible if the Data Manager is connected to the
network.

5.1.8.5 Data export
Data transfer is configured via the Modbus settings. All measured values are transferred
through this connection. As a bidirectional counter, the Data Manager measures active
power [W], reactive power [var], apparent power [VA] and power factor per phase and in
total, current [A] and voltage [V] per phase, and the network frequency [Hz].
The Data Manager provides a Modbus TCP server that uses the standard port 502 for
incoming connection enquiries. This port and the IP address must be configured to establish
a connection with the Data Manager.
Data export
In the case of data export, a CSV file is exported. This contains the instantaneous overall
consumption and the consumption of the individual sensors in € and kWh. To enable
recording of the values of the individual sensors in the CSV file, data transmission via
Modbus must be activated, and the individual phases must be assigned to the sensors. If
these settings are not made, only the overall consumption is recorded.
The following settings can be made in the "Data Export” dialog:
● Sensors that must appear in the CSV file
● Resolution: 15 min., 1 hour, 1 day and 1 week
Values for 15 min for max. 1 year
Values 1 day for max. 10 years
● Time frame: If the period extends back more than one week, representation in increments
of 15 minutes is no longer possible.

Data export with counter statuses and instantaneous values
As well as the data export described above, there is the option of exporting a CSV file with
the meter statuses and instantaneous values.
This export variant is automated, in other words, data are exported, saved and sent by email,
or stored on an FTP server over a specified period.
Here too, there is the option of activating data logging, which results in a CSV file being
saved to the hard disk at a specific resolution. In this file, you will find total power, overall
consumption, current, voltage, and power factor. These data are also included, divided
according to the different phases and the individual sensors.

The settings made and the meter statuses can be downloaded and saved at any time by
means of data backup. This data backup can be restored.

ESD guidelines
B
B.1 Electrostatic sensitive devices (ESD)
ESD components are destroyed by voltage and energy far below the limits of human
perception. Voltages of this kind occur as soon as a device or an assembly is touched by a
person who is not electrostatically discharged. ESD components which have been subject to
such voltage are usually not recognized immediately as being defective, because the
malfunction does not occur until after a longer period of operation.
ESD guidelines
CAUTION
Electrostatic sensitive devices
Electronic modules contain components that can be destroyed by electrostatic discharge.
These modules can be easily destroyed or damaged by improper handling.
• You must discharge your body electrostatically immediately before touching an
electronic component. To do this, touch a conductive, grounded object, e.g., a bare
metal part of a switch cabinet or the water pipe.
• Always hold the component by the plastic enclosure.
• Electronic modules should not be brought into contact with electrically insulating
materials such as plastic film, plastic parts, insulating table supports or clothing made of
synthetic fibers.
• Always place electrostatic sensitive devices on conductive bases.
• Always store and transport electronic modules or components in ESD-safe conductive
packaging, e.g. metallized plastic or metal containers. Leave the component in its
packaging until installation.
NOTICE
Storage and transport
If you have to store or transport the component in non-conductive packaging, you must first
pack the component in ESD-safe, conductive material, e.g., conductive foam rubber, ESD
bag.
The diagrams below illustrate the required ESD protective measures for electrostatic
sensitive devices.

Glossary
Application
Application software or computer program that executes a useful function for the user.
Balancing counter
The balancing counter calculates the total of energy flows of all three phases, and registers
this total according to the direction of the energy flow.
CSV file
This file format describes the structure of a text file for saving or exchanging simply
structured data. Spreadsheet programs such as Microsoft Excel can read in or export CSV
files.
IT system
Separation of all active parts from ground, or connection between a point and ground via an
impedance in the distribution system. Direct grounding of the exposed conductive part of the
electrical installation, regardless of existing grounding of a point in the supply system.
Modbus
One master and several slaves can be connected using Modbus. There are two versions,
one for the serial interface and one for Ethernet. Every bus node must have a unique
address. Any node may send messages over the bus. This is usually initiated by the master,
and an addressed slave replies
