Safety distance to transmitter antenna
2.3.1
Safety distance between transmitter antenna and personnel
For antenna configurations where it is possible to be briefly or constantly within the
transmission range of the antennas, as in loading ramps, for example, minimum distances
must be maintained.
Limits
The ICRP (International Commission of Radiological Protection) has worked out limit values
for human exposure to HF fields that are also recommended by the ICNIRP (International
Commission of Non Ionizing Radiological Protection). In German legislation on emissions
(since 1997), the following limit values apply. These can vary according to frequency:
Frequency f [MHz]
Electrical field strength E [V/m]
Magnetic field strength H [A/m]
10 - 400
27,5
0,073
400 - 2.000
1.375 x f1/2
0.0037 x f1/2
2.000 - 300.000
61
0,16
The limit values for the 900 MHz reader antenna alternating field are thus:
Electrical field strength: E = 41.25 V/m
Magnetic field strength: H = 0.111 A/m
HF power density: E x H = 4.57 W/m2

Safety Information
2.3 Safety distance to transmitter antenna
2.3.2
Minimum distance to antenna in accordance with ETSI
Minimum distance to antenna in accordance with ETSI (EU, EFTA, Turkey)
At a transmission frequency of 900 MHz, the wavelength of the electromagnetic wave λ is
approximately 0.34 m. For distances less than 1 λ in the near field, the electrical field strength
diminishes exponentially to the power three over distance, and for distances greater than 1 λ,
it diminishes exponentially to the power two over distance.
The horizontal line at 41.25V/m marks the "safety limit value".
For the maximum permisisble transmission power in accordance with ETSI (2W ERP), the
"safety distance" d = 0.24 m. This means that personnel should not remain closer than 24cm
to the transmitter antenna for extended periods (more than several hours without interruption).
Remaining within the vicinity of the antenna for a brief period, even for repeated periods (at a
distance < 0.24 m), is harmless according to current knowledge.

If the transmitter power is set lower than the highest permissible value (2 watts ERP), the
"safety distance" reduces correspondingly.

Note
Reduced maximum radiated power with RF620R/RF630R readers
The SIMATIC RF620R (ETSI) reader has a maximum radiated power of 0.5 W ERP. The
maximum safety distance is therefore 0.12 m.
The SIMATIC RF630R (ETSI) reader has a maximum transmitter power of 0.5 W. The
radiated power therefore depends on the antenna cable and the type of antenna used, but
must not exceed the 2 W ERP.
2.3.3
Minimum distance to antenna in accordance with FCC (USA)
Minimum distance to antenna in accordance with FCC (USA)
For the maximum permisisble transmission power in accordance with FCC (4W EIRP), the
"safety distance" d = 0.26 m. This means that personnel should not remain closer than 26cm
to the transmitter antenna for extended periods (more than several hours without interruption).
Remaining within the vicinity of the antenna for brief period, even repeated periods (at a
distance < 0.26 m) is harmless to health according to current knowledge.

The SIMATIC RF630R (ETSI) reader has a maximum transmitter power of 0.5 W. The
radiated power therefore depends on the antenna cable and the type of antenna used, but
must not exceed the 4 W EIRP.

System overview
3.1
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 RF670R reader and RF660R reader (write/read devices), 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
at the control level in order, for example, to generate the receiving department transaction for
the ERP (Enterprise Resource Planning) system at the business administration control level.
At the same time, the delivery can be automatically checked for correctness and completeness
prior to storage by means of the electronic delivery list.
The general automation and IT structure of a company is shown in the following figure. This
comprises several different levels that are described in detail below.

● Production control
The Manufacturing Execution System (MES) closes the gap between the data that arise in
the automation environment (control level) and the logistical and commercial processes of
the company (business administration control). MES solutions are used, for example, for
defining and performing production processes.
● Business administration control
This level covers planning and control of the equipment used. For this purpose, Enterprise
Resource Planning (ERP) systems and Supply Chain Management (SCM) systems are
used with modules for cost accounting, financial bookkeeping and personnel management.
● Global integration
Product information can be exchanged here at an inter-company level. This can be
performed over the Internet with the help of special services.
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,
transponder or tag - is attached to every item, package or pallet, and contains all important
information. The data medium receives the power it requires via an antenna which is also used
for data transmission.

Description
Due to its compact format and high degree of protection, the RF670R reader is ideally suited
to applications in production logistics and distribution. The integrated data processing makes
it easier to use in complex scenarios and reduces the IT integration costs. Integration is
performed using an XML protocol, TCP/IP and Ethernet.
Equipped with a rugged casing to the high IP 65 degree of protection and suitable for use over
a wide range of temperatures, the SIMATIC RF660R reader is also a match for the demands
of harsh industrial conditions in, for example, warehouses or on loading ramps.

Overview
You should observe the following criteria for implementation planning:
● Possible system configurations
● Antenna configurations
● Environmental conditions for transponders
● The response of electromagnetic waves in the UHF band
● Regulations applicable to frequency bands
● EMC Directives
4.2
Possible system configurations
The SIMATIC RF600 system is characterized by a high level of standardization of its
components. This means that the system follows the TIA principle throughout: Totally
Integrated Automation. It provides maximum transparency at all levels with its reduced
interface overhead. This ensures optimum interaction between all system components.
The RF600 system with its flexible components offers many possibilities for system
configuration. This chapter shows you how you can use the RF600 components on the basis
of various example scenarios.
4.2.1
Scenario for incoming goods
This example scenario shows the incoming goods bay of a warehouse. Pallets of goods are
delivered through the incoming goods portal of a warehouse. Each pallet is equipped with a
SIMATIC RF600

4.2 Possible system configurations
tag. The tags contain user data that provide information about the sender and receiver of the
goods. These data are read out and routed on.
Figure 4-1
Incoming goods bay
Features of the scenario
In this example, the maximum number of 4 antennas of the SIMATIC°RF660A type are
connected to the SIMATIC°RF670R reader. The four antennas are aligned with one read point
and therefore form a portal that is to be monitored. The reading ranges depend on the size of
the portal as well as the density of readers.
The tags in this scenario are Smart Labels of type SIMATIC°RF630L. They are usually attached
to a non-metallic base such as wooden crates or cartons, in which the goods are packed. The
tags can be mounted in almost any position on the packaging or pallet.
The tags are read with the "Bulk reading" procedure in the incoming goods bay, i.e. a large
number of items and many tags can be acquired at once. High read rates can be achieved in
this manner.

Scenario for material handling control
This scenario shows a possible solution for monitoring and controlling the infeed of material
to a production line. The objective is to provide the right material at the right time. This can be

4.2 Possible system configurations
particularly useful in plants with frequently changing manufacturing scenarios for ensuring that
incorrect infeed and downtimes are minimized.
Features of the scenario
The conveyor moves different transport containers past the readers in an arbitrary alignment.
The RFID tag is, however, always applied to the transport containers with the same alignment.
The tags in this scenario are transponders of type SIMATIC RF620T.
The conveyor has a maximum width of 80 cm in this example. The transport velocity is up to
2 m/s. With this arrangement only a single RFID tag has to be detected each time (single-tag).
In this scenario a SIMATIC RF630R is used as the reader. Optimum reading reliability is
ensured by two external SIMATIC RF660A antennas in a portal arrangement. Where the
distances to, or between, the materials containers are extremely short the SIMATIC RF620A
is an excellent alternative. The SIMATIC°RF630R reader reads the information from the tags
on the transport containers and transfers it via a communication module to the SIMATIC S7
controller which controls the process in accordance with the tag information.

Scenario for workpiece identification
A typical characteristic of modern manufacturing scenarios is their multitude of variations. The
individual data and production steps are stored in the tag of a toolholder or product. These
data are read by the machining stations during a production process and, if necessary, tagged
with status information. This can be used to dynamically identify which production step is the
next in the series. This has the advantage that the production line can work automatically
without the need to access higher system components. The use of RFID therefore increases
the availability of the plant.

4.2 Possible system configurations
Features of the scenario
RFID tags are attached to workpiece holders. Their spatial orientation is always identical. With
this arrangement, only a single tag has to be detected each time (single-tag). The tags in this
scenario are transponders of type SIMATIC RF640T.
The SIMATIC RF620R reader reads the information from the tags with its integrated antenna
and transfers it to the SIMATIC S7 controller via a communication module. Depending on the
stored tag information, the SIMATIC-S7 performs different control tasks, for example,
automatically providing a suitable tool for an industrial robot at the correct time.

Scenario for Intra logistics
Intra logistics comprises all logistical procedures that are required on a production site as well
as within the overall company. The main task of Intra logistics is to control the subsequent
processes:
● Transporting goods from the incoming goods bay into the warehouse
● Management of stock
● Conveyance of goods from the warehouse for production

4.2 Possible system configurations
● Order picking
● Packing
Features of the scenario
In this example scenario. items must be distributed to the correct storage location in a transport
container via a separating filter. The RFID tags of type SIMATIC RF630L are directly attached
to the item. The maximum transport velocity of the conveyor is 2 m/s.
In this scenario, bulk acquisition is necessary because several objects must be detected at
the same time.
The SIMATIC RF630R reader uses two external antennas in a portal arrangement to read the
information from the tags on the passing items and transfers it to the SIMATIC S7 controller
via a communication module. The SIMATIC S7 controls the separating filter of the conveyor
system depending on the tag information.
If only one simple evaluation of the tag ID is required, and the data will not undergo further
processing, the SIMATIC RF670R offers this function without interfacing to the controller.

In this example, the maximum number of 4 antennas of the SIMATIC°RF660A type are
connected to the SIMATIC°RF670R reader. The four antennas form two different read points
and therefore monitor two loading gates. The reading ranges depend on the size of the portal
as well as the density of readers.
The tags in this scenario are Smart Labels of type SIMATIC°RF630L. They are usually attached
to a non-metallic base such as wooden crates or cartons, in which the goods are packed. The

Antenna configuration 7:
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

The minimum distance between antennas mounted alongside each other or one above the
other depends on the transmit power of the reader and the sensing range of the tags.
For a portal configuration, the maximum distance between two antennas that are connected

The specified distances are recommended minimum or maximum values for configuration.
4.3.5
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 then occur particularly when they transmit on the same
channel (on the same frequency).
To prevent this, readers used in Europe and China must operate on different channels with
"Frequency hopping" activated. "Frequency hopping" is permanently set in the USA.
4.3.6
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.
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 (e.g., in rooms with
reflecting surfaces, machinery, or concrete walls), the
reading range can be significantly higher than in a lowreflection environment.
You will find detailed information about the reading range of the individual readers in the
"Technical specifications" in the sections for the various readers.
4.3.7
Operation of several readers within restricted space
4.3.7.1
Dense Reader Mode
A special operating mode for Gen 2 tags enables several RF600 readers to be operated without
interference in close proximity to each other. This applies to all RF600 readers: RF670R,
RF660R, RF630R and RF620R.

4.3 Antenna configurations
Dense Reader Mode (DRM)
In this mode, tag readability is increased through the application of interference-reducing
measures.
DRM is only defined for Gen 2 and does not function with other tag types.
Operating principle
Dense Reader Mode allows physically adjacent readers to use the same frequency when Gen
2 tags are being used.
In accordance with EPC Global as well as ETSI EN 302 208 V1.2.1, the four transmit channels
are used for transmission with the RF670R, with the RF660R in Firmware Version V1.3 and
higher, and with the RF620R/RF630R (see Section Regulations for UHF frequency bands in
Europe (ETSI EN 302 208 V1.2.1) (Page 54)) and the tag response appears on the
associated neighboring channels. As a result of the large difference in level between the
transmitter channels and the tag response channels, this technology provides great
advantages for frequency reuse. However, a prerequisite is that a certain minimum distance,
and thus minimum decoupling, is observed between the antennas of adjacent readers.
In accordance with EPC Global as well as ETSI EN 302 208 V1.1.1, only the even channels
are used for transmitting in this mode (communications path Reader -> Tag) with the RF660R
in Firmware Version V1.2 and below; the tag response is on the odd channels as a result of
the frequency offset.
Antenna alignment and distances
The minimum distance required between antennas that use the same frequency and that are
connected to different readers depends on the maximum radiated power set (RF670R with

Optimizing tag reading accuracy
A further improvement in the tag reading accuracy in an environment with a high density of
readers can be achieved by orienting the antennas toward the respective tag field, i.e. by
rotating them horizontally and vertically.
In addition, the transmitter power of the readers can be reduced down to the minimum at which
the tags are still just detected accurately.
This greatly reduces the probability of interference.

4.3.7.3
Optimization of robustness of tag data accesses for readers that are operated
simultaneously
Parameter data access reliability
If several readers are to be operated simultaneously in an environment, then the following
settings affect the reliability of the reader's access to transponder data:
● Electromagnetic environment (see Chapter The response of electromagnetic waves in the
UHF band (Page 51))
● Type of transponder (see chapter Transponder/tags (Page 205))
● Number of transponders to be detected by an antenna at a time
● Type of antenna (see Chapter Antennas (Page 153), Chapter Guidelines for selecting RFID
UHF antennas (Page 181), and Chapter Planning application (Page 84))
● Transponders' distance from and orientation toward antennas (see Chapter Transponder/
tags (Page 205))
● Distances and orientation of antennas of different readers to each other
● Radiated power of antennas
The robustness of tag data accesses is improved for readers whenever distances to adjacent
readers are increased, radiated power is reduced, and a channel plan (for ETSI readers) is
implemented. Adjacent readers are parameterized in the channel plan such that they cannot
use the same channels.
A channel plan can be created for ETSI readers; for FCC readers, it is assumed that the
probability of two readers accidentally using the same channel is very low.
SIMATIC RF620R reader
The RF620R has an integrated, circular polarized antenna. This means that the type of antenna
cannot be freely selected.
Note
Rotation of the reader through 90° around the z axis
Since the horizontal electrical opening angle of the RF620R antenna is greater than the
vertical electrical opening angle, the effects on adjacent readers can be reduced by rotating
the reader through 90° around the z axis (see coordinate diagram in Chapters Antenna
diagram for RF620R (ETSI) (Page 85) and Antenna diagram for RF620R (FCC)
(Page 88)).
SIMATIC RF670R, RF630R or RF660R reader with SIMATIC RF660A antenna
The electrical opening angles (vertical and horizontal) of the RF660A antenna are identical.
Therefore, the robustness of the readers' access to transponder data cannot be optimized
further by rotating them around the antenna axis.

Application example for RF620R/RF630R
The following example explains measures for enhancing the data access security from the
RF620R reader to transponders:
● The antennas are placed next to each other and are aligned in parallel (see arrangement
B in Chapter Dense Reader Mode (Page 46)).
● Radiated power is limited to 27 dBm (ERP) or 500 mW (ERP).
● The RF620R readers have been rotated through 90° around the z axis.
In addition, the following characteristics are to be fulfilled:
● Length of data to be read/written on the transponder: 99,99%
● Length of data to be read/written on the transponder: 512 bits (64 bytes)
● Transponder type RF630L (6GT2810-2AB03)

Frequency hopping
This technique should prevent mutual interference between readers. The reader changes its
transmission channel in a random or programmed sequence (FHSS).
Procedure for FCC
The 50 available channels mean that the probability is low that two readers will be operating
on the same frequency (see Section Regulations for UHF frequency bands in the USA
(Page 60)). In China, one reader operates on at least 2 channels, e.g. 16 channels of 2 W
(see Section Regulations for UHF frequency bands in China (Page 58)).

4.5 The response of electromagnetic waves in the UHF band
Procedure for ETSI
Frequency hopping is optional here. According to ETSI EN 203 208 V1.2.1, frequency hopping
is however recommended to ensure that the reader does not have to pause for 100 ms after
4 seconds.
4.3.7.5
Listen before talk
With this technique which is only applicable to ETSI, the reader checks whether the relevant
channel is assigned before transmission to prevent collisions. The reader will only transmit
when this channel is free. The reader can transmit for up to 4 seconds on this channel and
must then either pause for at least 100 milliseconds or jump immediately to an unassigned
channel where it can transmit for another 4 seconds.
With the new ETSI EN 302 208 standard V1.2.1 this technique must be not be used (see
Chapter Regulations for UHF frequency bands in Europe (ETSI EN 302 208 V1.1.2)
(Page 57) and Chapter Regulations for UHF frequency bands in Europe (ETSI EN 302 208
V1.2.1) (Page 54) ).
4.4
Environmental conditions for transponders/tags
4.4.1
Basic rules
The transponder/tag must not be placed directly on metal surfaces or on containers of liquid.
For 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 operates better
when the distance is greater (between 5 and 20 cm).
● Tag assembly on non-conductive material (plastic, wood) has a tendency to be less critical
than assembly even on poorly conductive material.
● The best results are achieved on the materials specified by the tag manufacturer.
● You can obtain more detailed information from the tag manufacturer.
4.5
The response of electromagnetic waves in the UHF band
4.5.1
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,
SIMATIC RF600

Draft Version 02.06.2010
51
RF600 system planning
4.5 The response of electromagnetic waves in the UHF band
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 transmitter 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 gaps in reader coverage.
4.5.2
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.
● Do not place metallic or conducting 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. For further details on the special case of attaching transponders to
electrically conducting materials, see Section SIMATIC RF620T (Page 235) and
SectionSIMATIC RF640T (Page 271) .
In the case of transponders that are not designed for mounting on metallic materials, the
minimum permissible distance from metal is 5 cm. The larger the distance between the
transponder and the metallic surface, the better the function of the transponder.
4.5.3
Influence of liquids and non-metallic substances
Non-metallic substances can also affect the propagation of electromagnetic waves.

Draft Version 02.06.2010
RF600 system planning
4.6 Regulations applicable to frequency bands
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.
4.5.4
Influence of external components
The R&TTE guideline and the relevant standards govern the electromagnetic compatibility
requirements. This also concerns the external components of the RF600 system. Even though
the requirements for electromagnetic compatibility have been specified, various components
will still interfere with each other.
The performance of the RF600 system is highly dependent on the electromagnetic
environment of the antennas.
Reflections and interference
On the one hand, antenna fields will be weakened by absorbing materials and reflected by
conducting materials. When electromagnetic fields are reflected, the antenna field and
reflecting fields overlap (interference).
External components in the same frequency band
On the other hand, external components can transmit on the same frequency band as the
reader. Or the external components can transmit in different frequency bands with side bands
that overlap with the frequency band of the reader. This results in a reduction of the "signal-tonoise" ratio which reduces the performance of an RF600 system.
If a DECT station that is transmitting in the 2 GHz band, for example, is located in the receiving
range of an antenna of the RF600 system, the performance of the write and read accesses to
the transponder will be affected.

4.7 Operation of RF600 readers according to EN 302208 V1.2.1 and EN 302208 V1.1.1
Note
If an RF660R reader with firmware version V1.3 is to replace a reader commissioned before
1 January 2010, the new reader can also use a firmware version older than V1.3. The
downgrade is described in the "RF660R Configuration Software" configuration manual.
Note
If possible, upgrade all older RF660R readers to the new firmware V1.3.
4.7.2
Disturbances when operating readers according to ETSI EN V1.1.1 and V1.2.1 in
mixed mode
If RF600 readers in the ETSI band (EU, EFTA & Turkey) are operated according to
EN 302 208 V1.1.1 (firmware V1.2) and at the same time to EN 302 208 V1.2.1 (Firmware
V1.3) in close proximity to each other (up to 20 m), these readers might interfere with each
other.
Reasons for interference
The following reasons may cause the interference:
● Only four transmission channels (865.7; 866.3; 866.9; 867.5 MHz) are now available
according to the latest ETSI standard.
● Deactivation of Listen Before Talking (LBT)
● When operating readers in mixed mode according to the old ETSI standard
(EN 302 208 V1.1.1) and the new ETSI standard (EN 302 208 V1.2.1), the transmission
and receive channels may interfere with each other. Tag reading might thus be blocked.
(See Chapter Possible causes of error (Page 67))
RF620R and RF630R
The RF620R (ETSI) and RF630R (ETSI) readers support both ETSI standards
EN 302 208 V1.1.1 and V1.2.1 (max. 4 channels without LBT). As of January 2010, these
readers must be operated using the 4-channel plan and without LBT.
RF660R
RF660R readers V1.2 or earlier firmware versions exclusively use a radio profile according to
EN 302 208 V 1.1.1 (max. 15 channels with LBT).
RF660R readers V1.3 or later firmware versions exclusively use a radio profile according to
EN 302 208 V1.2.1(max. 4 channels without LBT).

Preventing interference in mixed operation
If the RF660R readers use the air interface standards EPC Global Class 1 Gen 1,
EPC Global Class 1 Gen 2 (no dense mode) or ISO 18000-6B, the the receive channel is
identical to the respective transmission channel of a reader.

Mixed operation - dense mode
If the RF660R readers use the air interface standard EPC Global Class 1 Gen 2 (dense mode),
the receive channel is shifted by a "link frequency" compared to the respective transmission
channel of the reader (e.g. with profile 23 for RF660R, a link frequency of 160 kHz is used).
Thus the performance distribution of the tag responses in dense mode is within the channels
that are right next to a transmission channel.

Preventing interference in mixed operation
You ensure problem-free operation by a strict separation in the assignment of transmission
and receive channels of the RF600 readers according to EN 302 208 V1.1.1 and
EN 302 208 V1.2.1. This means that neither the transmission channels nor the receive
channels of the readers operated according EN 302 208 V1.1.1 must overlap with the
transmission or receive channels of the readers operated according to EN 302 208 V1.2.1.
Procedure
1. In the channel plan, only mark the transmission channels as assigned channels of a reader
for all readers that are not to operated in dense mode (EPC Global Class 1 Gen 1,
EPC Global Class 1 Gen 2 (no dense mode)) or ISO 18000-6B).
2. For all readers that are to operate in dense mode (EPC Global Class 1 Gen 1,
EPC Global Class 1 Gen 2 (dense mode)), mark the transmission channels and the
channels right next to them (receive channels) as assigned channels of a reader.
3. For this purpose, first mark all transmission channels and any adjacent receive channels
in dense mode operation of the R660R readers for V1.3 or later versions in the channel
plan. In mixed operation, the RF660R reader operated according to EN 302 208 V1.1.1
can use more channels than an RF660R reader operated according to EN 302 208 V1.2.1.
4. Then mark all transmission channels and any adjacent receive channels in dense mode
operation of the R660R readers for V1.2 or earlier versions in the channel plan.

4.7 Operation of RF600 readers according to EN 302208 V1.2.1 and EN 302208 V1.1.1
Example of planning a channel plan
Below you will find a concrete example of a channel plan with which you prevent interference:
● New readers operating according to EN 302 208 V1.2.1 must use channels with a channel
number below 107. Dense mode can be activated or deactivated.
● Readers according to the old standard EN 302 208 V1.1.1 can use channels with a channel
number between 109 and 114. If dense mode is activate, only even-numbered channels
can be used.
Such a setting prevents that readers interfere with each other. At which channel number the
separation will be depends on the ratio of readers according to the old standard and new
standard. This limit can be shifted as required.
4.7.3.3
Example 1: Recommended channel assignment mixed operation
This case refers to mixed operation of several readers according to EN 302 208 V1.1.1 with
standard profile and several readers according to EN 302 208 V1.2.1 in dense mode.
Transmission by reader 1 - according to EN 302208 V1.2.1 (4-channel plan, dense mode)
Transmission by reader 2 - according to EN 302208 V1.1.1 (15 channels, LBT)

If only a few readers operate according to EN 302 208 V1.1.1, the following channel
distribution is also possible:
● 3 channels for readers according to EN 302 208 V1.2.1
● 2 channels for readers according to EN 302 208 V1.1.1

Transmission capability for RF620R/RF630R
The basic setting of the RF620R and RF630R is the 4-channel plan without LBT and dense
mode.
Therefore the following applies:
If you operate the RF620R or RF630R in mixed mode with RF660R EN 302 208 V1.1.1, the
same settings apply as for mixed operation of RF660R according to EN 302 208 V1.2.1 in
dense mode and RF660R according to EN 302 208 V1.1.1.
4.7.4
Possible causes of error
If the channels are not separated in mixed operation, the following can occur:
Transmission by reader 1 - according to EN 302208 V1.2.1 (4-channel plan, dense mode)
Transmission by reader 2 - according to EN 302208 V1.1.1 (15 channels, LBT)
Receiving by reader 1 - according to EN 302208 V1.2.1 (4-channel plan, dense mode)
Receiving by reader 2 - according to EN 302208 V1.1.1 (15 channels, LBT)
Figure 4-14
Interference with adjacent readers in mixed operation
Transmission from readers 2 partially interfere with receiving by readers 1. Since readers 1 do
not have to adhere to LBT, they will block the transmission by readers 2 on these respective
channels. Furthermore, transmission from readers 1 blocks receiving by readers 2.
Other disturbances and causes
The following overview shows possible interference and its causes which can occur if the
channels are not separated in mixed mode.

Guidelines for electromagnetic compatibility (EMC)
4.8.1
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?
SIMATIC RF600
System Manual, 06/2010, J31069-D0171-U001-A10-7618

RF600 system planning
4.8 Guidelines for electromagnetic compatibility (EMC)
● 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 rectify defects in this area in the event of interference.
NOTICE
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.
4.8.2
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 external 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.

4.8 Guidelines for electromagnetic compatibility (EMC)
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 plant operator must comply with the locally applicable laws and regulations. They are
not covered in this document.
4.8.3
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:
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 against electromagnetic fields generated by inductances.
● 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-HF-impedance
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 power cables, signal cables and HF 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.

71
RF600 system planning
4.8 Guidelines for electromagnetic compatibility (EMC)
● Routing HF cables:
avoid parallel routing of HF cables.
● Do not route cables through the antenna field.
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.
4.8.4
Propagation of electromagnetic interference
Three components have to be present for interference to occur in a system:
● Interference source
● Coupling path
● Interference sink
Figure 4-15
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:

RF600 system planning
4.8 Guidelines for electromagnetic compatibility (EMC)
● 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.
Interference sources
In order to achieve a high level of electromagnetic compatibility and thus a very low level of
disturbance in a plant, it is necessary to recognize the most frequent interference sources.
These must then be eliminated by appropriate measures.

● Unfavorable cabinet configuration
4.8.5
Prevention of interference sources
A high level of immunity to interference can be achieved by avoiding interference sources. All
switched inductances are frequent sources 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.

4.8 Guidelines for electromagnetic compatibility (EMC)
Note
All coils in the cabinet should be suppressed. The valves and motor brakes are frequently
forgotten. Fluorescent lamps in the control cabinet should be tested in particular.
4.8.6
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 (EBS), the power components and non-power components must be combined.
● The equipotential bonding conductors of the separate modules must lead directly to the

The better the equipotential bonding in a plant, the smaller the chance of interference due to
fluctuations in potential.

4.8 Guidelines for electromagnetic compatibility (EMC)
Equipotential bonding should not be confused with protective earthing of a plant. Protective
earthing prevents the occurrence of excessive shock voltages in the event of equipment faults
whereas equipotential bonding prevents the occurrence of differences in potential.
4.8.7
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 4-19
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 (highfrequency clamp) or secured using cable ties. Care should be taken to ensure that the
connection allows good conductance.

Connection of shielding bus
The shielding bus must be connected to the PE busbar.
If shielded cables have to be interrupted, the shield must be continued via the corresponding
connector housing. Only suitable connectors may be used for this purpose.
Figure 4-21
Interruption of shielded cables
If intermediate connectors, which do not have a suitable shield connection, are used, the shield
must be continued by fixing cable clamps at the point of interruption. This ensures a large-area,
HF-conducting contact.

The RF620R has a circular polarized antenna. At 500 mW ERP radiated power, due to the
opening angle of the antennas, their fields can overlap considerably. It is no longer possible
to clarify in which antenna field access to the data of a tag is performed.
In order to avoid this, always keep a minimum distance of 3 m between two readers with the
maximum radiated power of 500 mW ERP.
Dense Reader Mode (DRM)
The readers can also interfere with each other (secondary fields), if the channels (Reader TX,
Transponder TX) overlap. In order to prevent a transponder channel overlapping with a reader
channel, we recommend that the Dense Reader Mode (DRM) is used.

Interpretation of directional radiation patterns
The following overview table will help you with the interpretation of directional radiation
patterns.
The table shows which dBi values correspond to which read/write ranges (in %): You can read
the radiated power depending on the reference angle from the directional radiation patterns,
and thus obtain information on the read/write range with this reference angle with regard to a
transponder.
The dBr values correspond to the difference between the maximum dBi value and a second
dBi value.

Example
As one can see from the section Antenna diagram for RF620R (ETSI) (Page 85), the maximum
antenna gain is 0 dB. In the Azimuth diagram, the antenna gain falls by 3°dB at approximately
± 39°. Therefore the dBr value is -3. The antenna range is only 50% of the maximum range at
± 39° from the Z axis within the horizontal plane.
5.1.2.5
Antenna/read point configurations
The RF620R reader has an internal circular polarized antenna. You can cover one read point
with this antenna. When several RF620R readers are used, the readers are addressed via the

5.2.2
Planning application
5.2.2.1
Minimum mounting clearances of two antennas of different readers
At 500 mW ERP radiated power, due to the opening angle of the antennas, their fields can
overlap considerably. It is no longer possible to clarify in which antenna field access to the
data of a tag is performed.
In order to avoid this, always keep a minimum distance of 3 m between two antennas of
different RF630R readers with the maximum radiated power of 500 mW ERP.
Dense Reader Mode (DRM)
The readers can also interfere with each other (secondary fields), if the channels (Reader TX,
Transponder TX) overlap. In order to prevent a transponder channel overlapping with a reader
channel, we recommend that the Dense Reader Mode (DRM) is used.
5.2.2.2
Antenna/read point configurations
You can connect up to two external antennas to the RF630R reader. The standard setting is
that two antennas are connected when the reader is started.
You have 3 possibilities for aligning the antennas and covering the read point.

One RF630R reader with two antennas and two read points
If you connect two external antennas to the device and align them in different directions, you
can read tags at two different read points. With this technique, a particular antenna must be
switched off application-dependently to be able to establish which tags have been read from
which antenna. The reader also provides a mode for this purpose in which the antennas can
be switched on and off cyclically (both antennas must be connected). Note the minimum
distances between the antennas for the antenna configuration (see Chapter Specified
minimum and maximum spacing of antennas (Page 44) .
One RF630R reader with two antennas and one read point
If you connect two external antennas to the device and align them in the same direction (portal
configuration), you can read tags at one read point. With this method, the reader automatically
switches between the two antennas while the tags are being read. Note the minimum distances
between the antennas for the antenna configuration (see Chapter Specified minimum and
maximum spacing of antennas (Page 44) .

If you connect an external antenna to the device, you can read tags at one read point.

Emitted radiation
The transmitter complies with the requirements of Health Canada and the FCC limit values
for subjecting persons to HF radiation, provided that a minimum spacing of 26 cm exists
between antenna and person. When the antennas are installed, you must therefore ensure
that a minimum spacing of 26 cm is maintained between personnel and antennas.

Configuration/integration
The RS422 system interface is provided for integrating the device into system environments/
networks. The system interface transfers data to SIMATIC controllers or PCs with the
appropriate interface.
Apart from transmitting communication data from the reader to the controller and vice versa,
the RS422 interface also supplies power to the reader (24 V DC).

Overview of configuration of the RF630R reader
The RF620R reader can alternatively be connected to a SIMATIC controller via the ASM 456,
ASM 475, RF170C and RF180C interface modules/communication modules.
The RF620R reader can alternatively also be connected directly to the PC via the RF182
communication module.

Antenna/read point configurations
You can connect up to four external antennas to the RF670R reader. The standard setting is
that four antennas are connected when the reader is started.
With RF-MANAGER Basic 2010 or RF-MANAGER 2008 with SP 3 and higher you can set up
various different configurations of antennas and/or reading points as required. It is possible to
find solutions to many different tasks through the number of data sources and subsequent
assignment of the antennas.
Examples of possible antenna/reading point configurations
● Four data sources each with one antenna for four different reading points.
● Two data sources each with two antennas for small portals.
● One data source with 4 antennas for large portals.
You will find further information in the online Help for the products.

CAUTION
Emitted radiation
The transmitter complies with the requirements of Health Canada and the FCC limit values
for subjecting persons to HF radiation, provided that a minimum spacing of 26 cm exists
between antenna and person. When the antennas are installed, you must therefore ensure
that a minimum spacing of 26 cm is maintained between personnel and antennas.

Configuration/integration
5.3.4.1
Configuration
An Ethernet interface is available for integrating the device into system environments/networks.
Over the Ethernet interface and with direct connection to the PC, the RF670R can be
configured in two different ways:
● Using RF-MANAGER Basic 2010
● Using RF-MANAGER 2008 Service Pack 3 and higher
The communication interface transfers the data over the RF-MANAGER interface to the IT,
ERP and SCM systems as well as to SIMATIC controllers. Alternatively the data is transferred
to user applications by means of XML commands.
Simple process controls (e.g. a traffic signal) can be directly implemented using the write/read
device via four digital inputs and outputs.

Grounding connection
A low-impedance earth connection ensures that interference signals generated, for example,
by external power supply cables or signal cables are safely discharged to earth.
Earthing connection
The ground terminal (M4 threads) on the
device (large surface, large-area contact) has
to be connected with the ground conductor of
the plant or the cabinet in which the reader is
to be installed.
The minimum conductor cross-section may
not be less than 2.5 mm2.

Firmware and software compatibility
CAUTION
Damage to the reader
The SIMATIC RF660R reader with firmware version V1.2 must only be configured and
operated with the relevant SIMATIC RF660R Configuration Software V1.2.
The SIMATIC RF660R reader with firmware version V1.3 must only be configured and
operated with the relevant SIMATIC RF660R Configuration Software V1.2 (limited
functionality) or V1.3.
No other combination of firmware and configuration software is permissible. The configuration
software V1.3 recognizes if it has been connected to a SIMATIC RF660R reader with firmware
version V1.3 or version 1.2.
Therefore always refer to the chapter "Firmware/Configuration Software Compatibility" of the
Configuration Manual before you make any changes to the firmware version or the version
of the SIMATIC RF660R Configuration Software.

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 RF660R reader:
During a defined time period, the reader transmits on one antenna and receives on the other.
As long as the antenna is receiving signals from further tags, the reader continues to transmit
on the same transmitter antenna until all responding tags have been identified. Subsequently,
or if no tags respond, the reader activates another antenna as the transmitter antenna. After
all the antenna have transmitted at least once and no tag has responded, or when the settling
time is excessively long, the reader activates frequency hopping (in the USA) or channel
selection (in Europe).

Connecting RF620A to RF670R
Preassembled standard cables (Page 155) in lengths of 3 m, 10 m and 20 m are available for
the connection.
The read range is limited by the cable loss. The maximum range can be achieved with the
6GT2815-0BH30 cable (length 3 m) since this has the lowest cable loss.
Connection of one, two or three antennas
When one, two or three antennas are used, we recommend that the remaining antenna
connection on the RF670R reader be sealed using the supplied protective cap.
Connection of four antennas
When using two antennas on the RF670R, there are no limitations to the positioning.

The read range is limited by the cable loss. The maximum range can be achieved with the
6GT2815-0BH30 cable (length 3 m) since this has the lowest cable loss.
At least two antennas must be connected in order to guarantee correct functioning.
Connection of two antennas
When two antennas are used, we recommend that the antennas be connected to the reader
as follows:
Figure 6-2
Configuration with RF660R
The RF620A antennas must always be arranged in pairs with the RF660R since one antenna
is needed for transmitting signals to the transponder whereas the other antenna receives the
signals from the transponder.
Note
Operation of the RF660R with more than two RF620A antennas does not offer optimum
performance!
More than two antennas should not be connected due to the functional design of the reader.
The optimum read rates cannot be achieved if you connect more than two RF620A antennas.
6.2.5
Alignment of transponders to the antenna
Polarization axis
Since the RF620A antenna has linear polarization, it is necessary to consider the alignment
of the transponders with regard to the polarization axis of the antenna.

Interpretation of directional radiation patterns
The following overview table will help you with the interpretation of directional radiation
patterns.
The table shows which dBi values correspond to which read/write ranges (in %): You can read
the radiated power depending on the reference angle from the directional radiation patterns,

The dBr values correspond to the difference between the maximum dBi value and a second
dBi value.

Example
As one can see from the Antenna pattern ETSI (Page 163), the maximum antenna gain is
-5 dBi. In the vertical plane, the antenna gain has dropped to approx. -11 dBi at +40° and 320°.
Therefore the dBr value is -6. The antenna range is only 50% of the maximum range at ± 40°
from the Z axis within the vertical plane (see values shown in blue in the directional radiation
pattern: characteristic of the vertical plane of the antenna (Page 163) and the associated
representation of the reference system (Page 163)).

Read/write ranges
The following tables show the typical read/write ranges of RF600 readers which are connected
to the RF620A antenna via the 3 m antenna cable (1 dB loss) and various types of tags.
Note
Please note that tolerances of ±20% are admissible due to production and temperature
conditions.
When using other antenna cables, the ranges listed here are reduced as a result of the higher
antenna cable losses in the following manner:

The radiation diagram is shown for horizontal alignment and for a center frequency of 865
MHz. Horizontal antenna alignment is provided when the TNC connection on the antenna
points vertically up or down.
The radiating/receiving angle of the antenna is defined by the angle between the two -3 dB
points (corresponding to half the power referred to the maximum performance at a 0° angle).
The optimum radiating/receiving angle is therefore approximately ±30 degrees.

Interpretation of directional radiation patterns
The following overview table will help you with the interpretation of directional radiation
patterns.
The table shows which dBi values correspond to which read/write ranges (in %): You can read
the radiated power depending on the reference angle from the directional radiation patterns,
and thus obtain information on the read/write range with this reference angle with regard to a
transponder.
The dBr values correspond to the difference between the maximum dBi value and a second
dBi value.

Example
As one can see from the section Antenna pattern (Page 177), the maximum antenna gain is
6 dBi. In the vertical plane, the antenna gain has dropped to approx. 3 dBi at +30°. Therefore
the dBr value is -3. The antenna range is only 50% of the maximum range at ± 30° from the
Z axis within the vertical plane.

Environmental conditions
CAUTION
Damage to the device
In line with the application, you must take into consideration the mechanical loads (shock
and vibration) as well as environmental demands such as temperature, moisture, UV
radiation.
The device could be damaged if these factors are not considered.

General procedure
Depending on whether you wish to use a third-party antenna or antenna cable - or both - in
combination with the SIMATIC RF660R reader, these instructions will help you to select the
components and to set the important parameters in the SIMATIC RF660R configuration
software.
There are two different application cases:

6.4 Guidelines for selecting RFID UHF antennas
● Selection of third-party components:
you wish to select appropriate third-party components for the SIMATIC RF600 system and
to subsequently configure the reader for these components.
● Configuration of existing third-party components:
you already have third-party components (antenna, antenna cable or both) and wish to
appropriately configure the reader for these components.
Procedure for selecting third-party components
Always proceed in the following order during your considerations and the practical
implementation:
1. Consider which third-party components you wish to use in the SIMATIC RF600 system.
2. Depending on the third-party component required, refer either to Section Antennas
(Page 185) or Section Antenna cables (Page 196) for the important criteria for selection
of your components. The selection criteria/parameters are sorted in descending relevance.
3. Use the specified equations to calculate your missing parameters, and check whether the
required values are reached (e.g. antenna gain) and that important secondary values (e.g.
cable loss) are not exceeded or undershot.
4. Configure the reader with the parameters of your third-party components. You can usually
carry this out in the SIMATIC RF660R configuration software. The exact procedure is
described in Section .
5. For advanced users or in exceptional cases, e.g. input of an antenna gain <4.0 dBi), it is
recommendable to carry out the configuration directly using XML commands. For further
information, refer to Section .
Procedure for configuration of existing third-party components
If you already have third-party components which you wish to integrate into the SIMATIC
RF600 system, proceed as follows:
1. Depending on the third-party component, refer either to Section "Antennas" or Section
"Antenna cables" for the important criteria of your components. The parameters are sorted
in descending relevance.
2. Compare the limits with the data of your antenna or cable vendor.
3. Subsequently proceed exactly as described above in "Procedure for selecting third-party
components" from Paragraph 3. onwards.

6.4.4.1
Types of antenna and properties
Basically all types of directional antennas can be considered as third-party antennas for
integration into the SIMATIC RF600 system. Directional antennas have a preferred direction
in which more energy is radiated than in other directions.
6.4.4.2
Antenna parameters
Overview
The properties of an antenna are determined by a large number of parameters. You must be
aware of these properties in order to make the correct selection for your appropriate UHF
antenna. The most important parameters are described below. These important parameters
are described in detail in the following sections. The following parameters describe both the
send and receive functions of the antenna (reciprocity). The antenna is a passive antenna. A
two-way relationship exists.
● Radiated power
● Antenna gain
● Impedance
● Return loss / VSWR
● Power rating
● Polarization
● Front-to-back ratio
● Beam width
Radiated power
In order to comply with national directives with regard to the radiated power (which differ
depending on the location or country of use), the RF660R reader together with the antenna
cable(s) and antenna(s) must be exactly parameterized or configured.
This means that the product of the transmitted power P0 of the reader and the antenna gain
G must always have the correct ratio with regard to the radiated power "EIRP" depending on
the location of use or the permissible frequency band.
Calculation of the radiated power is briefly described below.
Calculation of the radiated power
The radiated power is the total power radiated by the antenna in the room. The isotropic radiator
serves as the physical computing model which uniformly radiates the power into the room
(spherically).

Antennas
6.4 Guidelines for selecting RFID UHF antennas
EIRP
Directional antennas combine the radiation, and therefore have a higher power density in the
main beam direction compared to an isotropic radiator. To enable antennas of different design
or Directional characteristic to be compared with one another, the equivalent isotropic radiated
power (EIRP) has been introduced which represents the effective power which must be applied
to an isotropic radiator in order to deliver the same power density in the main beam direction
of the antenna.
EIRP is the product of the transmitted power P0 and the antenna gain G:
EIRP = P0 * G
ERP
Also common is specification of the equivalent radiated power referred to the half-wave dipole
"ERP" (effective radiated power):
Logarithmic and standardized data
Approximate calculations are easier to carry out as additions than as products, therefore the
logarithms are taken for the above equations and the power data standardized to 1 mW and
specified in decibels (dBm or dBi).
Calculation of the radiated power with consideration of the cable loss ak
If the transmitted power is not applied directly but via a cable with loss aK, this loss should be
compensated such that the same radiated power is obtained.
If the loss is not appropriately compensated, the radiated power is too small.
General preliminary information on the unit "dB"
Requirements
This section provides you with information on the unit "decibel". This knowledge is a
requirement for optimum understanding of the following section. You can ignore this section
if you already have the appropriate knowledge.

Antennas
6.4 Guidelines for selecting RFID UHF antennas
Definition
When specifying decibels, the ratios between powers or voltages are not defined directly but
as logarithms. The decibel is therefore not a true unit but rather the information that the
specified numerical value is the decimal logarithm of a ratio of two power or energy variables
P1 and P2 of the same type.
This ratio is defined by the following equation:
Example:
If P1 = 200 W and P2 = 100 mW, how large is the ratio a in dB?
Use with other units
As with other units, there are also different versions of the unit for decibel depending on the
reference variable. With this reference, the logarithmic power ratio becomes an absolute
variable. The following table lists the most important combinations in this context with other
units:
Versions of decibel
Description
0 dBm
Power level with the reference variable 1 mW.
dBi
Power level with the reference variable on the isotropic spherical
radiator (see also Section Antenna gain (Page 187) ).
Antenna gain
Definition
The antenna gain specifies the degree to which the antenna outputs or receives its power in
the preferred angle segment.
With this theoretical variable, a comparison is always made with an isotropic spherical radiator,
a loss-free antenna which does not exist in reality. It describes how much power has to be
added to the isotropic spherical radiator so that it outputs the same radiated power in the
preferred direction like the antenna to be considered. The unit for the antenna gain is therefore
specified in dBi (dB isotropic).

Antennas
6.4 Guidelines for selecting RFID UHF antennas
The antenna gain is defined for the receive case as the ratio between the power received in
the main beam direction and the received power of the isotropic spherical radiator.
Specifications
You must know the antenna gain in the corresponding frequency band or range. You can obtain
the value of the antenna gain from the technical specifications of your antenna vendor.
● With a cable loss of 4 dB, a gain ≥ 6 dBi(L) is required since otherwise the maximum radiated
power will not be achieved.
● In the case of antennas used in the FCC area of approval, a gain of at least 6 dBi(L) is
required since otherwise the permissible radiated power of 4 W EIRP will not be reached.
● If the gain is > 6 dBi(L)*, the difference is compensated in accordance with the directives
by reducing the transmitted power.
* (L) is the reference to the linear polarization.
Dependencies
● Frequency dependency:
if a frequency dependency exists in the frequency band used, you must apply the highest
value in each case for the antenna gain. With the cable loss, on the other hand, you must
select the smallest value in each case it frequency dependency exists.
This procedure means that the permissible radiated power will not be exceeded in the
extreme case.
● Dependency on the plane
If the data for the antenna gain are different in the horizontal and vertical planes, you must
use the higher value in each case.
Impedance
Definition
Impedance is understood as the frequency-dependent resistance. The impedances of the
antenna, reader and antenna cables should always be the same. Differences in the impedance
result in mismatching which in turn means that part of the applied signal is reflected again and
that the antenna is not fed with the optimum power.
Specifications
● Only antennas can be used whose connection has a characteristic impedance of Z =
50 Ohm.
● The mechanical design of the coaxial antenna connection is of secondary importance; N,
TNC and SMA plug connectors are usual.

Antennas
6.4 Guidelines for selecting RFID UHF antennas
Return loss / VSWR
Definition
Since the impedance at the antenna connection is frequency-dependent, mismatching
automatically occurs with broadband use. This mismatching can be reflected by two
parameters:
● The voltage standing wave ratio VSWR
● The return loss
Voltage standing wave ratio VSWR
The power sent by the transmitter cannot flow unhindered to the antenna and be radiated as
a result of the mismatching described by the VSWR. Part of the power is reflected at the
antenna and returns to the transmitter. The powers in the forward and reverse directions
produce a standing wave which has a voltage maximum and a voltage minimum. The ratio
between these two values is the VSWR (voltage standing wave ratio).
Return loss
The return loss parameter is based on the reflection factor which describes the voltage ratio
between the forward and reverse waves.
Specifications
So that the smallest possible transmitted and received powers are reflected by the antenna
under ideal conditions, you should observe the following data for the VSWR and the return
loss |S11|/ dB in the respective frequency band (865-870 MHz or 902-928 MHz):
● VSWR < 1.24:1 or
● |S11|/ dB ≥ 20 dB
Power rating
Definition
The power rating is understood as the maximum power defined by the vendor with which the
device may be operated.
Specifications
Third-party antennas must be dimensioned for an effective power applied to the antenna
connection of at least 4 Watt.

Polarization
Definition
The polarization parameter describes how the electromagnetic wave is radiated by the
antenna. A distinction is made between linear and circular polarization. With linear polarization,
a further distinction is made between vertical and horizontal polarization.
Specifications
UHF transponders usually have a receive characteristic similar to that of a dipole antenna
which is linearly polarized. Horizontal or vertical polarization is then present depending on the
transponder mounting.
Selection of circular polarized antenna
If the orientation of the transponder is unknown, or if an alternating orientation can be expected,
the transmit and receive antennas must have circular polarization.
When selecting a circular antenna, the polarization purity must be observed in addition to the
polarization direction. A differentiation is made between left-hand and right-hand circular
polarization (LHCP and RHCP). The two types cannot be combined in the same system. On
the other hand, selection of the polarization direction is insignificant if the antenna system of
a transponder is linearly polarized. With actual antennas, elliptical polarization is encountered
rather than the ideal circular polarization. A measure of this is the ratio between the large and
small main axes of the ellipse, the axial ratio (AR), which is frequently specified as a logarithm.

Selection of linear polarized antenna
When using linear polarized antennas, you must always make sure that the transmitter
antenna, receiver antenna and transponder have identical polarizations (vertical or horizontal).

Front-to-back ratio
Definition
As a result of their design, directional antennas not only transmit electromagnetic waves in the
main beam direction but also in other directions, particularly in the reverse direction. The largest
possible suppression of these spurious lobes is expected in order to reduce faults and to keep
the influence on other radio fields low. This attenuation of spurious lobes in the opposite
direction to the main beam is called the front-to-back ratio.
Specifications
Requirement: The front-to-back ratio must be ≥ 10 dB. This requirement also applies to
spurious lobes illustrated by the following graphics in Section Half-value width (Page 193).

Half-value width
Definition
A further description of the directional characteristic is the beam width. The beam width is the
beam angle at which half the power (-3 dB) is radiated referred to the maximum power. The
antenna gain is directly related to the beam width. The higher the antenna gain, the smaller
the beam angle.
Coupling in ETSI
In ETSI EN 302 208 (release version V1.2.1 2008-06), the radiated power is coupled to the
beam width, i.e.
● Radiated power 500-2000 mW ERP: beam width ≤ 70 degrees
The beam width requirement applies to both the horizontal and vertical planes. The FCC
directives do not envisage coupling with the beam width.
The following graphics show examples of the directional radiation pattern of an antenna in
polar and linear representations for which both the horizontal and vertical planes must be
considered.

Activation or reading range
The reading range depends on the horizontal and vertical beam widths in the case of equal
distances from the transmitter antenna. Depending on the mechanical mounting and the ratio
between the vertical beam width ① and the horizontal beam width ②, read areas result as
shown in the following graphic:

Selection criteria
You must observe the criteria listed below when selecting the appropriate antenna cable for
your third-party antenna.
Characteristic impedance
Definition
If the input impedance of a device does not agree with the cable impedance, reflections occur
which reduce the power transmission and can result in the appearance of resonance and thus
to a non-linear frequency response.
Specifications
● You must only use coaxial antenna cables when connecting a third-party antenna.
● This antenna cable must have a nominal characteristic impedance of Z = 50 Ohm.
Antenna cable loss
In order to be able to transmit the available UHF power from the SIMATIC RF660R reader to
the antenna(s), the antenna cable loss must not exceed a value of approx. 4 dB.

6.4 Guidelines for selecting RFID UHF antennas
Dependency of the cable loss
The cable loss depends on two important factors:
● External characteristics of cable. These includes the cable length, diameter and design.
● As a result of the physical principle, the cable loss is also frequency-dependent, i.e. the
cable loss increases at higher transmitter frequencies. Therefore the cable loss must be
specified in the frequency band from 860 to 960 MHz.
Cable vendors usually provide tables or calculation aids for their types of cable which usually
include the transmitter and receiver frequencies as well as the cable length. Therefore contact
your cable vendor in order to determine the appropriate type of cable using the approximate
value referred to above.
6.4.5.2
Notes on use
Shielding of the antenna cable
Coaxial antenna cables always have a shielded design and therefore radiate little of the
transmitted power to the environment.
Note
Cable with double shielding
You should therefore preferentially select cable with double shielding since this provides the
best damping.
Bending radius of the antenna cable
The properties of the cable shield are influenced by mechanical loading or bending. You must
therefore observe the static and dynamic bending radii specified by the cable vendor.
Connectors and adapters
You must use connectors and adapters of type "Reverse Polarity R-TNC" (male connector)
for your antenna cables from a third-party supplier in order to guarantee correct connection to
the SIMATIC RF660R reader.
The figure below shows the standard for a suitable thread:
You can find more information in the catalog data of your cable vendor.
