3.2.1 RF300 system overview
SIMATIC RF300 is an inductive identification system specially designed for use in industrial
production for the control and optimization of material flow.
Thanks to its compact dimensions, RF300 is the obvious choice where installation conditions
are restricted, especially for assembly lines, handling systems and workpiece carrier
systems. RF300 is suitable for both simple and demanding RFID applications and it stands
out for its persuasive price/performance ratio.
The RF300 offers a particularly low-cost solution concept for low-performance applications.
The high-performance components of RF300 provide advantages in terms of speed.

Communication
modules
A communication module (interface module) is used to integrate the RF identification system in
PLC/automation systems.
Readers The reader (read/write device) ensures inductive communication, supplies power to the transponder,
and handles the connection to the various PLCs (e.g. SIMATIC S7) through the communication module
(e.g. ASM 475).
Transponder The transponder (data memory) stores all data relevant to the production process and is used, for
example, instead of barcode.
Conventions
The RF310R, RF340R and RF380R readers are equipped with an integral antenna, whereas
the RF350R reader is operated over an external antenna. In this system manual, the term
"Reader" is used throughout even where it is actually referring to the antenna of the reader.

4.1.2 Transmission window and read/write distance
The reader generates an inductive alternating field. The field is strongest near to the reader.
The strength of the field decreases in proportion to the distance from the reader. The
distribution of the field depends on the structure and geometry of the antennas in the reader
and transponder.
A prerequisite for the function of the transponder is a minimum field strength at the
transponder achieved at a distance Sg from the reader or the ANT1. The picture below
shows the transmission window between transponder and reader or ANT1:

The transponder can be used as soon as the intersection (SP) of the transponder enters the
area of the transmission window.
From the diagrams above, it can also be seen that operation is possible within the area
between Sa and Sg. The active operating area reduces as the distance increases, and
shrinks to a single point at distance Sg. Only static mode should thus be used in the area
between Sa and Sg.

4.1.3 Width of the transmission window
Determining the width of the transmission window
The following approximation formula can be used for practical applications:
% y/
B: Width of the transmission window
L: Length of the transmission window
Tracking tolerances
The width of the transmission window (B) is particularly important for the mechanical tracking
tolerance. The formula for the dwell time is valid without restriction when B is observed.
4.1.4 Impact of secondary fields
Secondary fields in the range from 0 to 20 mm always exist.
They should only be applied during planning in exceptional cases, however, since the
read/write distances are very limited. Exact details of the secondary field geometry cannot be
given, since these values depend heavily on the operating distance and the application.

4.1.7 Dwell time of the transponder
The dwell time is the time in which the transponder remains within the transmission window
of a reader. The reader can exchange data with the transponder during this time.

0,8: Constant factor used to compensate for temperature impacts and production
tolerances
The dwell time can be of any duration in static mode. The dwell time must be sufficiently long
to allow communication with the transponder.
The dwell time is defined by the system environment in dynamic mode. The volume of data
to be transferred must be matched to the dwell time or vice versa. In general:

4.1.8 Communication between communication module, reader (with IQ-Sense interface)
and transponder
Communication between the communication module (IQ-Sense), RF310R reader and
transponder takes place in fixed telegram cycles. 3 cycles of approximately 3 ms are always
needed for the transfer of a read or write command. 1 or 2 bytes of user data can be
transferred with each of these commands. The acknowledgement transfer (status or read
data) takes place in 3 further cycles. The transponder must be present within the field of the
reader during the message frame cycle.
Calculation of the communication time for interference-free transfer
The communication time for fault-free data transfer is calculated as follows:
=+ ⋅tKtn
KByte
(n >1)
Calculation of the maximum amount of user data
The maximum amount of user data is calculated as follows:

4.2 Field data for transponders, readers and antennas
The following table shows the field data for all SIMATIC RF300 components of transponders
and readers. It facilitates the correct selection of a transponder and reader.
All the technical specifications listed are typical data and are applicable for an ambient
temperature of between 0 C and +50 °C, a supply voltage of between 22 V and 27 V DC and
a metal-free environment. Tolerances of ±20 % are admissible due to production or
temperature conditions.
If the entire voltage range at the reader of 20 V DC to 30 V DC and/or the entire temperature
range of transponders and readers is used, the field data are subject to further tolerances.
Note
Transmission gaps
If the minimum operating distance (Sa) is not observed, a transmission gap can occur in the
center of the field. Communication with the transponder is not possible in the transmission
gap.

NOTICE
Adherence to the values specified in the "Minimum distance from reader to reader" table is
essential. The inductive fields may be affected if the distance is smaller. In this case, the
data transfer time would increase unpredictably or a command would be aborted with an
error.
If the specified minimum distance cannot be complied with due to the physical configuration,
the SET-ANT command can be used to activate and deactivate the HF field of the reader.
The application software must be used to ensure that only one reader is active (antenna is
switched on) at a time.

4.4 Installation guidelines
4.4.1 Overview
The transponder and reader complete with their antennas are inductive devices. Any type of
metal, in particular iron and ferromagnetic materials, in the vicinity of these devices will affect
their operation. Some points need to be considered during planning and installation if the
values described in the "Field data" section are to retain their validity:
● Minimum spacing between two readers or their antennas
● Minimum distance between two adjacent data memories
● Metal-free area for flush-mounting of readers or their antennas and transponders in metal
● Mounting of multiple readers or their antennas on metal frames or racks
The following sections describe the impact on the operation of the identification system when
mounted in the vicinity of metal.

Flush-mounting of transponders and
readers is possible in principle.
However, the size of the
transmission window is significantly
reduced. The following measures
can be used to counteract the
reduction of the window:
Remedy:
PP [!PP
5HD
Enlargement of the non-metallic
spacer below the transponder
and/or reader.
The transponder and/or reader are
10 to 20 mm higher than the metal
surround.
(The value x ≥ 100 mm is valid, e.g.
for RF310R. It indicates that, for a
distance x ≥ 100 mm, the reader
can no longer be significantly
affected by metal.)
Remedy:
DD
E
E5HD
Increase the non-metallic distance
a, b.
The following rule of thumb can be
used:
• Increase a, b by a factor of 2 to 3
over the values specified for
metal-free areas
• Increasing a, b has a greater
effect for readers or
transponders with a large limit
distance than for readers or
transponders with a small limit
distance.

Mounting of several readers on metal frames or racks
Any reader mounted on metal couples part of the field to the metal frame. There is normally
no interaction as long as the minimum distance D and metal-free areas a, b are maintained.
However, interaction may take place if an iron frame is positioned unfavorably. Longer data
transfer times or sporadic error messages at the communication module are the result.

4.4.3 Effects of metal on different transponders and readers
Mounting different transponders and readers on metal or flush-mounting
Certain conditions have to be observed when mounting the transponders and readers on
metal or flush-mounting. For more information, please refer to the descriptions of the
individual transponders and readers in the relevant section.
4.4.4 Impact on the transmission window by metal
In general, the following points should be considered when mounting RFID components:
● Direct mounting on metal is allowed only in the case of specially approved transponders.
● Flush-mounting of the components in metal reduces the field data; a test is
recommended in critical applications.
● When working inside the transmission window, it should be ensured that no metal rail (or
similar part) intersects the transmission field.
The metal rail would affect the field data.
The impact of metal on the field data (Sg, Sa, L, B) is shown in tabular format in this section.
The values in the table describe the reduction of the field data in % with reference to non-
metal (100 % means no impact).

The housing of the heat-resistant data storage unit is made of polyphenylene sulfide (PPS).
The chemical resistance of the data storage unit is excellent. No solvent is known that can
dissolve the plastic at temperatures below 200 °C. A reduction in the mechanical properties
has been observed in aqueous solutions of hydrochloric acid (HCl) and nitric acid (HNO3) at
80 °C. The excellent resistance to all fuel types including methanol is a particular
characteristic. The following table provides an overview of the chemicals investigated.

72 System Manual, 09/2007, J31069 D0166-U001-A5-7618
4.6 EMC Directives
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 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.

System Manual, 09/2007, J31069 D0166-U001-A5-7618 73
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 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.
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.

4.6.3 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:
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.
● 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.

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

LQWHUIHUHQFH
Figure 4-28 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.

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.

4.6.5 Cabinet configuration
The influence of the user in the configuration of an electromagnetically compatible plant
encompasses cabinet configuration, cable installation, ground connections and correct
shielding of cables.
Note
For information about electromagnetically compatible cabinet configuration, please consult
the installation guidelines for SIMATIC PLCs.
Shielding by enclosure
Magnetic and electrical fields and electromagnetic waves can be kept away from the
interference sink by using a metal enclosure. The easier the induced interference current can
flow, the greater the intrinsic weakening of the interference field. All enclosures and metal
panels in the cabinet should therefore be connected in a manner allowing good
conductance.
Figure 4-30 Shielding by enclosure
If the control cabinet panels are insulated from each other, a high-frequency-conducting
connection can be established using ribbon cables and high-frequency terminals or HF
conducting paste. The larger the area of the connection, the greater the high-frequency
conductivity. This is not possible using single-wire connections.

Prevention of interference by optimum configuration
Good interference suppression can be achieved by installing SIMATIC PLCs on conducting
mounting plates (unpainted). When setting up the control cabinet, interference can be
prevented easily by observing certain guidelines. Power components (transformers, drive
units, load power supply units) should be arranged separately from the control components
(relay control unit, SIMATIC S7).
As a rule:
● The effect of the interference decreases as the distance between the interference source
and interference sink increases.
● The interference can be further decreased by installing grounded shielding plates.
● The load connections and power cables should be installed separately from the signal
cables with a minimum clearance of 10 cm.

System Manual, 09/2007, J31069 D0166-U001-A5-7618 81
Filtering of the supply voltage
External interference from the mains can be prevented by installing line filters. Correct
installation is extremely important, in addition to appropriate dimensioning. It is essential that
the line filter is mounted directly at the cabinet inlet. As a result, interference is filtered
promptly at the inlet, and is not conducted through the cabinet.

4.6.6 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.

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.

4.6.7 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
equipotential bonding strip.

Figure 4-34 Equipotential bonding (EBS = Equipotential bonding strip)
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 shock voltages in the event of equipment
faults whereas equipotential bonding prevents the occurrence of differences in potential.

4.6.8 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 HF-
proof shield contact is necessary
Figure 4-35 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.

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 4-37 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.

5.1 Overview
The reader ensures inductive communication with the transponders, and handles the serial
connection to the communication modules/interface modules and 8xIQ-Sense module.
Communication between the transponder and reader takes place over inductive alternating
fields.
The transmittable data volume between reader and transponder depends on:
● the speed at which the transponder moves through the transmission window of the
reader.
● the length of the transmission window.
● the transponder type (FRAM, EEPROM).
