RF System SIMATIC RF600
SIMATIC RF600 is an identification system that operates in the UHF range. UHF technology
supports large write/read distances with passive tags.
The SIMATIC RF660-R read/write devices (readers), fitted for example on the gate of a
warehouse, automatically record every movement of goods, and signal these to the host
systems. The data are filtered and compressed there by data management software in order,
for example, to generate the receiving department transaction for the ERP system. At the
same time, the delivery can be automatically checked for correctness and completeness
prior to storage by means of the electronic delivery list.

3.1.1
Application areas of RF600
RFID (radio frequency identification) permits interruption-free tracking and documentation of
all delivered, stocked and shipped goods in the incoming goods, warehouse, production
logistics and distribution departments. A small data medium - referred to as SmartLabel or
tag - is adhered to every item, package or palette, and contains all important information.
The data medium receives the power it requires via an antenna which is also used for data
transmission.
Equipped with a rugged casing to the high IP 65 degree of protection and suitable for use
over a wide range of temperatures, the reader is also a match for the demands of harsh
industrial conditions in, for example, warehouses or on loading ramps.

4.2 Antenna configurations
4.2.2
Possibilities and application areas for antenna configurations
Some basic antenna configurations and possible fields of application are shown below.
Antenna configuration 1:
Description/ application areas
This arrangement of antennas is appropriate when the tags
to be read are only located on one side of the items to be
identified, e.g. when palettes are to be identified on which
the tags to be read must be on a prespecified side.
â‘  Tag
Antenna configuration 2:
Description/ application areas
Preferred application: In the identification of goods in
loading portals. The tag is located in the field of radiation of
two antennas; for reliable tag reading, the height of the tag
above floor level must therefore be known with reasonable
accuracy.

4.2 Antenna configurations
Antenna configuration 3:
Description/ application areas
Preferred application: In the identification of goods in
loading portals. Similar to configuration 2, but with additional
reading reliability when the tag is at an angle to the vertical.
â‘  Tag
Antenna configuration 4:
Description/ application areas
Preferred application: In the identification of goods in
loading portals. The tag is located in the field of radiation of
all four antennas, so the tag position can vary more than in
configuration 2 for reliable tag identification.

4.2 Antenna configurations
Antenna configuration 5:
Description/ application areas
Preferred application: In the identification of goods in
loading portals. Similar to configuration 4, but the reliability
of tag identification is improved as a result of the four
antennas at separate locations, so the tag position is not
critical.
â‘  Tag
Antenna configuration 6:
Description/ application areas
This tunnel configuration is suitable for conveyor belt
applications. The goods with the tags to be read are moving
forwards on a conveyor belt but the alignment of the tags
relative to the antennas is not clearly defined. One of the
antenna is located on the floor and radiates vertically
upwards in the direction of the conveyor belt. A relatively
high reading reliability is achieved due to the use of four
antennas.

4.2 Antenna configurations
4.2.3
Tag orientation in space
The alignment of the tag antenna to the antenna of the reader affects the reading range. For
maximum performance and to achieve the maximum reading range, the tag antenna should
therefore be aligned in parallel with the reader antenna:
Parallel tag alignment
Large reading range
Maximum probability of identification of tags.
Perpendicular tag alignment
Minimal reading range
Minimum probability of identification of tags.

4.2.5
Mutual interference of readers (antennas)
Using more than one reader
When several RFID readers are used, there is a danger that RFID tags can also be read by
other readers. It must be ensured that the tag can only be identified by the appropriate
reader.
Technical faults between readers can then only occur when they transmit on the same
channel, i.e. in the same frequency range of a frequency band.
To prevent this, the RF660R reader uses the "Listen before talk" technique in Europe or
frequency hopping between many different channels in the USA.

4.2 Antenna configurations
4.2.6
Reading range
The reading range between the reader (antenna) and the transponder is affected by the
following factors:
The reading range depends on
Description
Transmit power of the reader
The higher the transmit power of the reader, the larger the
reading range.
Tag size and type
The larger the tag antenna, the larger the power input area
and therefore the larger the reading range.
Absorption factor of the materials
The higher the absorption of the surrounding material, the
smaller the reading range.
Antenna amplification
The bigger the antenna amplification, the larger the reading
range.
Production quality of the tag
The better the tag has been matched to the operating
frequencies during manufacturing, the greater the reading
range
Reflection characteristics of the
environment
In a multiple-reflection environment, the reading range can
be significantly higher than in a low-reflection environment.

4.2.7
Increasing the probability of identification for tags - Antenna switching
To achieve a high probability of reading tags, the antenna switching function has been
implemented in the RF600R reader:
At a given time, the system transmits on one antenna and receives on the other antennas.
As long as the antenna is receiving signals from further tags, the system continues to
transmit on the same transmit antenna until all responding tags have been identified.
Subsequently, or if no tags respond, the system activates another antenna as the transmit
antenna. After all the antenna have transmitted at least once, or when the settling time is
excessively long, the reader activates frequency hopping (in the USA) or channel selection
(in Europe).

physical reasons, a minimum distance must be maintained between the tag antenna and
conductive material. A minimum distance of 5 cm is recommended. The tag function is
improved with greater distances (between 5 and 20 cm).
The best performance is achieved when the tag is mounted on a non-conductive material
such as plastic or wood.
Exception:
Tags that are designed for direct mounting on metal.

The response of electromagnetic waves in the UHF band
4.4.1
The effect of reflections and interference
Reflections and interference
Electromagnetic waves in the UHF band behave and propagate in a similar manner to light
waves, that is they are reflected from large objects such as ceilings, floors, walls and
windows and interfere with each other. Due to the nature of electromagnetic waves,
interference can lead to wave amplification which can produce an increased reading range.
In the worst case, interference can also result in waves being extinguished which causes
holes in reader coverage.
Reflections can also be beneficial when they cause electromagnetic waves to be routed
around objects to a certain extent (deflection). This can increase the reading probability.
Due to these electromagnetic characteristics, it is extremely difficult in the multiple-reflection
environment that is usually found in the real environment on site, to determine propagation
paths and field strengths for a particular location.
Reducing the effect of reflections/interference on tag identification
• Reducing the transmit power:
To reduce interference to a minimum, we recommend that the transmit power of the
reader is reduced until it is sufficient for an identification rate of 100 %
• Increasing the number of antennas to 3 or 4:
More antennas in a suitable antenna configuration can prevent gap in reader coverage

4.4 The response of electromagnetic waves in the UHF band
4.4.2
Influence of metals
Metal can have an effect on the electromagnetic field depending on the arrangement or
environment. The effect ranges from a hardly determinable influence through to total
blocking of communication. The term metal in this context also includes metallized materials
that are either coated with metal or shot through with metal to such an extent that UHF
radiation cannot penetrate or only to a minimal extent.
The effect of metal on the electromagnetic field can be prevented as follows:
• Do not mount tags on metal
• Ensure there are no metallic objects at close range to the antenna
• Ensure there are no metallic objects in the propagation field of the antenna and
transponder
Tags mounted directly onto metal
In general, tags must not be mounted directly onto metallic surfaces. Due to the nature of the
magnetic field, a minimum distance must be maintained between the tag antenna and
conductive materials.
The minimum distance to metal must be greater than 5 cm. The larger the distance, the
better the function of the transponder.
Exception:
Tags that are designed for direct mounting on metal.

4.4.3
Influence of liquids and non-metallic substances
Non-metallic substances can also affect the propagation of electromagnetic waves.
When non-metallic substances or objects are located in the propagation field that can absorb
UHF radiation, these can alter the antenna field depending on their size and distance and
can even extinguish the field entirely.
The high-frequency damping effect of water and materials with a water content, ice and
carbon is high. Electromagnetic energy is partly reflected and absorbed.
Liquids and petroleum-based oils have low HF damping. Electromagnetic waves penetrate
the liquid and are only slightly weakened.

Guidelines for electromagnetic compatibility (EMC)
4.6.1
Overview
These EMC Guidelines answer the following questions:
• Why are EMC guidelines necessary?
• What types of external interference have an impact on the system?
• How can interference be prevented?
• How can interference be eliminated?
• Which standards relate to EMC?
• Examples of interference-free plant design
The description is intended for "qualified personnel":
• Project engineers and planners who plan system configurations with RFID modules and
have to observe the necessary guidelines.
• Fitters and service engineers who install the connecting cables in accordance with this
description or who can rectify defects in this area in the event of interference.
Warning
Failure to observe notices drawn to the reader's attention can result in dangerous
conditions in the plant or the destruction of individual components or the entire plant.

4.6 Guidelines for electromagnetic compatibility (EMC)
4.6.2
What does EMC mean?
The increasing use of electrical and electronic devices is accompanied by:
• Higher component density
• More switched power electronics
• Increasing switching rates
• Lower power consumption of components due to steeper switching edges
The higher the degree of automation, the greater the risk of interaction between devices.
Electromagnetic compatibility (EMC) is the ability of an electrical or electronic device to
operate satisfactorily in an electromagnetic environment without affecting or interfering with
the environment over and above certain limits.
EMC can be broken down into three different areas:
• Intrinsic immunity to interference:
immunity to internal electrical disturbance
• Immunity to ambient interference:
immunity to external electromagnetic disturbance
• Degree of interference emission:
emission of interference and its effect on the electrical environment
All three areas are considered when testing an electrical device.
The RFID modules are tested for conformity with the limit values required by the CE and
RTTE guidelines. Since the RFID modules are merely components of an overall system, and
sources of interference can arise as a result of combining different components, certain
guidelines have to be followed when setting up a plant.
EMC measures usually consist of a complete package of measures, all of which need to be
implemented in order to ensure that the plant is immune to interference.
Note
The plant manufacturer is responsible for the observance of the EMC guidelines; the plant
operator is responsible for radio interference suppression in the overall plant.
All measures taken when setting up the plant prevent expensive retrospective modifications
and interference suppression measures.
The salient national specifications and regulations must be observed. They are not covered
in this document.
4.6.3
Basic rules
It is often sufficient to follow a few elementary rules in order to ensure electromagnetic
compatiblity (EMC). The following rules must be observed:

4.6 Guidelines for electromagnetic compatibility (EMC)
Shielding by enclosure
• Protect the device against external interference by installing it in a cabinet or housing.
The housing or enclosure must be connected to the chassis ground.
• Use metal plates to shield the device against electromagnetic fields.
• Use metal connector housings to shield data conductors.
Wide-area ground connection
• Bond all passive metal parts to chassis ground, ensuring large-area and low-HFimpedance contact.
• Establish a large-area connection between the passive metal parts and the central
grounding point.
• Don't forget to include the shielding bus in the chassis ground system. That means the
actual shielding busbars must be connected to ground by large-area contact.
• Aluminium parts are not suitable for ground connections.
Plan the cable installation
• Break the cabling down into cable groups and install these separately.
• Always route high-voltage and signal cables through separated ducts or in separate
bundles.
• Feed the cabling into the cabinet from one side only and, if possible, on one level only.
• Route the signal cables as close as possible to chassis surfaces.
• Twist the feed and return conductors of separately installed cables.
• Cable routing of HF cables:
Avoid installing cables in parallel over long distances and maintain minimum distances
between the cables (at least 25 cm)

4.6 Guidelines for electromagnetic compatibility (EMC)
Shielding for the cables
• Shield the data cables and connect the shield at both ends.
• Shield the analog cables and connect the shield at one end, e.g. on the drive unit.
• Always apply large-area connections between the cable shields and the shielding bus at
the cabinet inlet and make the contact with clamps.
• Feed the connected shield through to the module without interruption.
• Use braided shields, not foil shields.
Line and signal filter
• Use only line filters with metal housings
• Connect the filter housing to the cabinet chassis using a large-area low-HF-impedance
connection.
• Never fix the filter housing to a painted surface.
• Fix the filter at the control cabinet inlet or in the direction of the source.

Propagation of electromagnetic interference
Three components have to be present for interference to occur in a system:
• Interference source
• Coupling path
• Interference sink

Propagation of interference
If one of the components is missing, e.g. the coupling path between the interference source
and the interference sink, the interference sink is unaffected, even if the interference source
is transmitting a high level of noise.
The EMC measures are applied to all three components, in order to prevent malfunctions
due to interference. When setting up a plant, the manufacturer must take all possible
measures in order to prevent the occurrence of interference sources:
• Only devices fulfilling limit class A of VDE 0871 may be used in a plant.
• Interference suppression measures must be introduced on all interference-emitting
devices. This includes all coils and windings.
• The design of the system must be such that mutual interference between individual
components is precluded or kept as small as possible.
Information and tips for plant design are given in the following sections.

These must then be eliminated by appropriate measures.

4.6.5
Prevention of interference sources
A high level of immunity to interference can be achieved by avoiding interference sources.
All switched inductances are a frequent source of interference in plants.
Suppression of inductance
Relays, contactors, etc. generate interference voltages and must therefore be suppressed
using one of the circuits below.
Even with small relays, interference voltages of up to 800 V occur on 24 V coils, and
interference voltages of several kV occur on 230 V coils when the coil is switched. The use
of freewheeling diodes or RC circuits prevents interference voltages and thus stray
interference on conductors installed parallel to the coil conductor.

4.6.6
Equipotential bonding
Potential differences between different parts of a plant can arise due to the different design
of the plant components and different voltage levels. If the plant components are connected
across signal cables, transient currents flow across the signal cables. These transient
currents can corrupt the signals.
Proper equipotential bonding is thus essential.
• The equipotential bonding conductor must have a sufficiently large cross section (at least
10 mm2).
• The distance between the signal cable and the associated equipotential bonding
conductor must be as small as possible (antenna effect).
• A fine-strand conductor must be used (better high-frequency conductivity).
• When connecting the equipotential bonding conductors to the centralized equipotential
bonding strip, the power components and non-power components must be combined.

Equipotential bonding
The better the equipotential bonding in a plant, the smaller the chance of interference due to
fluctuations in potential.
Equipotential bonding should not be confused with protective earthing of a plant. Protective
earthing prevents the occurrence of excessive contact voltages in the event of device faults.

4.6.7
Cable shielding
Signal cables must be shielded in order to prevent coupling of interference.
The best shielding is achieved by installing the cables in steel tubes. However, this is only
necessary if the signal cable is routed through an environment prone to particular
interference. It is usually adequate to use cables with braided shields. In either case,
however, correct connection is vital for effective shielding.
Note
An unconnected or incorrectly connected shield has no shielding effect.
As a rule:
• For analog signal cables, the shield should be connected at one end on the receiver side
• For digital signals, the shield should be connected to the enclosure at both ends
• Since interference signals are frequently within the HF range (> 10 kHz), a large-area HFproof shield contact is necessary
Figure 4-9
Cable shielding
The shielding bus should be connected to the control cabinet enclosure in a manner allowing
good conductance (large-area contact) and must be situated as close as possible to the
cable inlet. The cable insulation must be removed and the cable clamped to the shielding
bus (high-frequency clamp) or secured using cable ties. Care should be taken to ensure that
the connection allows good conductance.

Transponder/tags
7.1
Mode of operation of transponders
The tag/transponder mainly comprises a microchip with an integral memory and a dipole
antenna.
The principle of operation of a passive RFID transponder is as follows:
• Diversion of some of the high-frequency energy emitted by the reader to supply power to
the integral chip
• Commands received from reader
• Responses are transmitted to the reader antenna by modulating the reflected radio
waves (backscatter technique)

Warning
Danger to life
It is not permitted to open the device or to modify the device.
The following must also be taken into account:
• Failure to observe this requirement shall constitute a revocation of the CE approval and
manufacturer's warranty.
• For installation of the power supply, compliance with the DIN/VDE requirements or the
country-specific regulations is essential.
• The field of application of the power supply is limited to "Information technology in
electrical office equipment" within the scope of validity of the EN 60950/VDE 0805
standard.
• When the equipment is installed, it must be ensured that the mains socket outlet is freely
accessible. The housing can reach a temperature of +25 °C without any adverse
consequences. It must, however, be ensured that the power supply is covered in the case
of an ambient temperature of more than +25°C to protect persons from contact with the
hot housing. Adequate ventilation of the power supply must be maintained under these
conditions.
