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:

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/m

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 (1/r) 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 41.25 V/m marks the "safety limit value".

For the maximum permitted transmit power (1/r

) in accordance with ETSI (2 W ERP), the "safety distance" is d = 0.24 m. This means that personnel should not remain closer than 24 cm to the transmitter antenna for extended periods (for 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.

The values for this are as follows:

System overview of SIMATIC RF600

3.1 Application areas of RF600

● Acquisition level

This level contains the RFID readers that read the appropriate transponder data and transfer it to the next higher level.

● Control level

At the control level, the RFID data is collected, preprocessed and made available to the production control and business administration control levels for further processing.

● IT level

The Manufacturing Execution System (MES) closes the gap between the data that arises in the automation environment (control level) and the logistic and commercial processes of the company (business administration control). MES solutions are used, for example, for defining and performing production processes.

3.1 Application areas of RF600

RFID (radio frequency identification) permits continuous identification, tracking and documentation of all delivered, stocked and shipped goods in the incoming goods, warehouse, production, 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.

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 number of interfaces. This ensures optimum interaction between all system components.

The RF600 system with its flexible components offers many possibilities for system configuration. This section shows you how you can use the RF600 components on the basis of various example scenarios.

4.2 Possible system configurations

4.2.1 Intralogistics scenario

This scenario describes the transport of material via conveyor systems that are made up of large numbers of standard elements. They are characterized by long distances, frequent branches (separators, infeed and outfeed), standardized transport containers and high movement speeds. The installation space available for identification technology is limited, and the high number of read points demands a low-cost solution.

Due to the high movement speeds of transport containers in some cases, the limited space available and the fact that the read points are sometimes located very close together, the use of the RF600 system with space-saving antennas and a low transmit power can be recommended.

Features of the scenario

Intralogistics (material flow)

Figure 4-1 Scenario: Intralogistics (material flow)

The conveyor transports the transport containers past the antennas. The transponders attached to the transport containers are always evenly aligned. The transponders in this scenario are transponders of the type SIMATIC RF630L. The conveyor belt has a maximum width of approximately 80 cm in this example. The maximum transport speed is 2 m/s. With this arrangement, only a single transponder needs to be detected each time (single-tag).

In this scenario, SIMATIC RF680R and RF685R are used as readers. Due to the limited space available and the low reading distances, the SIMATIC RF615A antennas are used in this example. As an alternative - with greater available space and to guarantee optimum read reliability - the SIMATIC RF650A antennas can also be used. Because the readers are connected in a bus topology, wiring requirements are reduced.

The reader reads the information from the transponders on the transport containers and forwards it to the SIMATIC S7 controller.

Intralogistics (separator)

Figure 4-2 Scenario: Intralogistics (separator)

In this example scenario, items must be distributed to the correct storage location in a transport container via a separator. The transponders attached to the transport containers are always evenly aligned. The transponders in this scenario are transponders of the type SIMATIC RF630L. The conveyor belt has a maximum width of approximately 80 cm in this example. The maximum transport speed of the conveyor belt is 2 m/s.

In this scenario, a SIMATIC RF615A with a SIMATIC RF615A external antenna is used as the reader. With the RF615R, a reader combining multiple advantages is used. In addition to its compact design, this low-cost reader is also characterized by low cabling requirements.

When a transport container passes the light barrier the transponder on the transport containers and forwards it to the SIMATIC S7 controller. The SIMATIC S7 controls the separator transponder information.

The SIMATIC RF650M mobile reader is used in this example for additional evaluation and visualization of the article data directly on site.

4.2 Possible system configurations

4.2.2 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 transponder of a tool holder 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.

Figure 4-3 Scenario: Workpiece identification

Features of the scenario

Transponders are attached to workpiece holders. Their spatial orientation is always identical. With this arrangement, only a single transponder needs to be detected each time (singletag).

The SIMATIC RF685R reader reads the information from the transponders with its integrated antenna or the external antenna RF680A and transfers it to the SIMATIC S7 controller. Depending on the stored transponder information, the SIMATIC S7 controller different control tasks, for example, automatically providing a suitable tool for an industrial robot at the correct time.

In a metallic wireless environment or when lots of readers/antennas are mounted close together we recommend that you do not have the readers reading permanently. Instead execute specific read/write commands when an object/transponder is located in front of an antenna or passes it. This "triggering" can be implemented with light barriers or beros. This procedure reduces mutual influence/disruption of the read points and increases the

identification quality of the wanted transponders while reducing the identification of unwanted transponders.

4.2.3 Goods tracking scenario

In this scenario, a gate consisting of a SIMATIC RF650R reader and four antennas checks the goods passing through the gate. All stored goods are equipped with transponders. A traffic light indicates whether the goods may leave the warehouse.

Figure 4-4 Scenario: Goods tracking

Features of the scenario

In this example scenario, the export of goods from a warehouse is checked using the SIMATIC RF650R reader and four SIMATIC RF650A antennas connected to it. A sensor registers when a vehicle passes the gate and reports this to the higher-level system, which then triggers a read operation via the reader.

The reader reads the information from the transponders on the goods and forwards it to the user application, which checks the status of the goods. The traffic light is set to green or red depending on whether the goods are released.

4.2 Possible system configurations

4.2.4 Scenario incoming goods, distribution of goods and outgoing goods

The scenario consists of an RFID system with three readers. The SIMATIC RF650R reader with its four antennas identifies the incoming/outgoing products at the incoming/outgoing goods gates of a factory building hall through which pallets are delivered. Each pallet is fitted with a transponder. The transponders contain user data that provides information about the sender and receiver of the goods. This data is read out and passed on. The goods supplied on the pallets are processed in the factory and then exit the factory through the outgoing goods gate.

Figure 4-5 Scenario: Incoming goods, distribution of goods and outgoing goods

Features of the scenario

In this example scenario, the SIMATIC RF685R reader is controlled by a light barrier and monitors a conveyor belt; the conveyor belt transports the goods towards two output gates that are assigned to different recipients. Each item has a transponder that is always fitted at the same position and with the same alignment on the item. These transponders also contain user data that provides information about the sender and receiver of the goods. There is a separator at the end of the conveyor belt that determines the output gate to which the goods should be directed. The separator is set according to the results from the reader and the goods are distributed.

Light barriers are installed to control the reader. Depending on the read results of the reader, the outgoing portal opens, or it remains closed.

Some basic antenna configurations and possible fields of application are shown below.

With the various configurations, please note that up to four external antennas can be connected to the RF650R and F680R readers, while one external antenna can be connected to the RF615 and RF685R readers. The RF615R and RF685R readers also have an internal antenna.

This arrangement of antennas is appropriate when the transponders to be read are only located on one side of the goods to be acquired, for example, if a conveyor belt with passing goods has to be monitored during production and it is precisely defined on which side the transponders to be read are attached.

① Transponder

This tunnel configuration is suitable for conveyor belt applications. The goods with the transponders to be read are moving forwards on a conveyor belt but the alignment of the transponders relative to the antennas is not clearly defined. One of the antenna is located on the floor and radiates vertically upwards in the direction of the conveyor belt. A relatively high reading reliability is achieved due to the use of four antennas.

In the portal configuration, multiple antennas are connected to one reader. In this case, the antennas must not exceed the maximum distance to one another.

Optimization of the antenna arrangement

With the RF685R reader (with internal antenna)

The RF685R reader has an integrated switchable antenna (circular or linear polarization).

With the RF640A/RF642A/RF660A antennas

The electrical aperture angles (vertical and horizontal) of the RF660A antenna are identical, with the RF640A/RF642A antennas they are similar. Therefore, the robustness of the readers' access to transponder data cannot be optimized for the RF660A and with the RF640A/RF642A it can be optimized only to a limited extent by rotating around the antenna axis.

Reflection characteristics of the environment

Number of transponders in the antenna field

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 low-reflection

The typical ranges always relate to a transponder installed at the maximum possible distance from the antenna.

If there are several transponders located in the antenna field, the distances to all other transponders must not exceed the maximum possible distance to be able to be detected from the antenna field.

The width and height of the antenna field within which its transponders can be arranged at a certain distance from the antenna depend on the following:

• The radiated power,

• Only reading or reading and writing of the transponders

(writing requires more power, typically double the power)

• The aperture angle (horizontal)

• The aperture angle (vertical)

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 Static/dynamic mode

Reading or writing can be either static or dynamic.

● Reading/writing is counted as being static if the tag does not move in front of the antenna

and is read or written.

● Reading/writing is counted as being dynamic if the tag moves past the antenna during

reading/writing.

4.3.8 Operation of several readers within restricted space

4.3.8.1 Using more than one reader

When mounting the readers make sure that there is a minimum clearance of 0.5 m between the readers to avoid them influencing each other.

Avoiding problems

When several RFID readers are used, there is a danger that RFID transponders can also be read out by other readers. Care must therefore be taken to ensure that the transponder can only be identified by the intended reader.

Technical disruptions between readers then occur particularly when they transmit on the same channel (on the same frequency). You will find more detailed information in the section "The response of electromagnetic waves in the UHF band (Page 55)".

4.3.8.2 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 section "The response of electromagnetic waves in the UHF band (Page 55)")

● Type of transponder (see section "Transponder (Page 333)")

● Number of transponders to be detected by an antenna at a time

● Type of antenna (see section "Antennas (Page 205)" and section "Guidelines for

selecting RFID UHF antennas (Page 51)")

● Transponders' distance from and orientation to antennas (see section "Transponder (Page 333)")

● Distances and orientation of antennas of different readers to each other

● Radiated power of antennas

The robustness of transponder data access 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 in such a way that they do not use the same channels.

A channel plan can be created for ETSI and CMIT readers; for FCC readers, it is assumed that the probability of two readers accidentally using the same channel is very low.

4.3.8.3 Frequency hopping

This technique is intended to prevent mutual interference between readers. The reader changes its transmission channel in a random or programmed sequence (FHSS).

Procedure for FCC

Frequency hopping is always active in the FCC country profile. With 50 available channels the probability is low that two readers will be operating on the same frequency. In China, one reader operates on at least 2 channels, e.g. sixteen 2 watt channels.

You will find more information on frequency ranges in the section "Regulations applicable to frequency bands (Page 86)".

Procedure for ETSI

Frequency hopping is optional in the ETSI wireless profile. According to ETSI EN 203 208 V1.4.1, frequency hopping is required in multi-channel operation; without it, only single-channel operation is possible. In this mode, the reader pauses for 100 ms after each 4 s transmission period to comply with the standard.

4.3.9 Guidelines for selecting RFID UHF antennas

4.3.9.1 Note safety information

Before planning how to use third-party components, as the operator of a system that comprises both RF600 components and third-party components, you must comply with the safety information in Section Safety instructions for third-party antennas as well as for modifications to the RF600 system (Page 19).

4.3.9.2 Preconditions for selecting RFID UHF antennas

Target group

This section is aimed at configuration engineers who thoroughly understand and wish to carry out the selection and installation of an antenna or a cable for the SIMATIC RF600 system. The various antenna and cable parameters are explained, and information is provided on the criteria you must particularly observe. Otherwise this chapter is equally suitable for theoretical and practice-oriented users.

4.3 Antenna configurations

Purpose of this chapter

This section will help you to select the suitable antenna or the suitable cable taking into account all important criteria and to make the relevant settings in the configuration software/WBM of the SIMATIC RF600 system. Correct and safe integration into the SIMATIC RF600 system is only possible following adaptation of all required parameters.

4.3.9.3 General application planning

Overview of the total SIMATIC RF600 system and its influencing factors

In the following graphic you can see the design of a SIMATIC RF600 reader with connected antenna and the influencing factors. The influencing factors affect the radiated power output.

Radiated power = transmit power ± influencing factors

You must be aware of these influencing factors and also consider them if you wish to integrate components such as antennas or cables into the system. These influencing factors are described in more detail in sections "Antennas (Page 205)" and "Antenna cables (Page 53)".

Figure 4-9 Overview diagram: Influencing factors

When operating the SIMATIC RF600 system, you need to observe additional influencing factors such as minimum spacing between antennas in the room.

NOTICE

Damage to the device

4.3 Antenna configurations

Environmental conditions

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.

Specifying the transmit / radiated power

Depending on whether you want to use a third-party antenna and/or antenna cable with a reader, you need to select the suitable components. When selecting third-party components orient yourself on the values of comparable Siemens products.

With the readers, the parameters for the transmit/radiated power, antenna gain and cable loss (user-defined) are set using the WBM. In the WBM, you can select the Siemens products being used from a drop-down list quickly and easily, and the values and their effect on the transmit/radiated power are calculated directly. With third-party products, you can enter the relevant values manually.

Based on the entered products/values, the WBM calculates the permitted radiated power and makes sure that this is not exceeded.

4.3.9.4 Types of antenna

In principle, all types of directional antennas can be considered as antennas for integration into the SIMATIC RF600 system. Directional antennas have a preferred direction in which more energy is radiated than in other directions.

RF600 antennas on the other hand, are optimized for operation with RF600 readers and have all the required approvals.

4.3.9.5 Antenna cables

Selection criteria

You must observe the criteria listed below when selecting the appropriate antenna cable.

Characteristic impedance

Note the following points when selecting the antenna cable:

● You can only use coaxial antenna cables when connecting an antenna.

SIMATIC RF600 System Manual, 11/2018, J31069-D0171-U001-A21-7618

● These antenna cables must have a nominal characteristic impedance of Z = 50 Ohm.

RF600 system planning

4.3 Antenna configurations

Antenna cable loss

In order to be able to transmit the available UHF power from the RF600 reader to the antenna or antennas, the antenna cable loss should not exceed a value of approx. 5 dB.

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. In other

words, the cable loss increases the higher the transmitter frequency is. 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.

Notes on use

Shielding of the antenna cable

Coaxial antenna cables generally have a shielded design and therefore radiate little of the transmitted power to the environment.

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 the type "Reverse Polarity R-TNC" (male connector) for your antenna cables to ensure correct connection to the RF600 reader interface.

Figure 4-10 Thread standardization

You can find more information in the catalog data of your cable vendor.

4.4 Environmental conditions for transponders

Basic rules

The transponder must not be placed directly on metal surfaces or on containers of liquid. The on-metal transponders designed specifically for use in metallic environments are an exception to this. For physical reasons, a minimum distance must be maintained between the transponder antenna and conductive material. A minimum distance of 5 cm is recommended. The transponder operates better when the distance is greater (between 5 and 20 cm).

● Transponder 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 transponder

manufacturer.

● For more information, refer to the section "Transponder (Page 333)" or ask the relevant

transponder 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 scenario, interference can also result in waves being extinguished which causes gaps in reader coverage.

In some circumstances, reflections can also be beneficial when they cause electromagnetic waves to be routed around objects, in a sense (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 real environments on site to determine propagation paths and field strengths for a particular location.

SIMATIC RF600 System Manual, 11/2018, J31069-D0171-U001-A21-7618

RF600 system planning

4.5 The response of electromagnetic waves in the UHF band

Reducing the effect of reflections/interference on transponder identification

● Reducing the transmit power: To minimize interference, we recommend that the transmit power of the reader is reduced until it is sufficient for an identification rate of 100%.

● Increasing the number of antennas: More antennas (3 or 4) 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 transponders on metal.

The on-metal transponders designed specifically for use in metallic environments are an exception to this.

● Do not place metallic or conducting objects in the propagation field of the antenna and transponder.

Influence of metal on transponders

Normally transponders must not be mounted directly on metallic surfaces. The transponders designed specifically for use in metallic environments are an exception to this (e.g.: RF690L, RF620T, RF625T, RF630T, RF640T, RF680T).

Due to the nature of the electromagnetic field, a minimum distance must be maintained between the transponder antenna and conductive materials. For more detailed information on the special case of attaching transponders to electrically conducting materials, refer to the relevant transponder sections.

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.

Influence of metal on antennas

Note that metal surfaces located directly in the antenna field reflect the transmitted power directly to the antenna. Due to the nature of the electromagnetic field, a minimum distance must be maintained between the antenna and conductive materials. You can find more detailed information on this in section "Specified minimum and maximum spacing of antennas (Page 46)".

If the reflected energy becomes too strong in the receive path of the reader, this activates a protective circuit that shows itself as an antenna error without there actually being an error in the configuration or a defect on the antenna.

SIMATIC RF600

56 System Manual, 11/2018, J31069-D0171-U001-A21-7618

RF600 system planning

4.5 The response of electromagnetic waves in the UHF band

This effect depends very much on the transmitted power, the components being used (cable, antenna) and the distance from the metallic surface to the antenna. In this case, repositioning/realigning the antenna or reducing the radiated power can remedy the situation.

4.5.3 Influence of liquids and non-metallic substances

Non-metallic substances can also affect the propagation of electromagnetic waves and thus the transponder range.

When non-metallic substances or objects that can absorb UHF radiation are located in the propagation field, these can alter the antenna field depending on their size and distance and can even extinguish the field entirely.

The RF damping effect of water, materials containing water, ice and carbon is high. Electromagnetic energy is partly reflected and absorbed.

Oil- or petroleum-based liquids have low RF damping. Electromagnetic waves penetrate these liquids and are only slightly weakened.

4.5.4 Influence of external components

The RED guideline and the relevant standards govern the electromagnetic compatibility requirements. This also concerns the third-party components of the RF600 system. Even though requirements for electromagnetic compatibility are defined, 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).

Third-party components in the same frequency band

On the other hand, third-party components may transmit on the same frequency band as the reader, or the third-party components may 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-to-noise" 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 access to the transponder may be reduced.

4.6 Planning and installation of UHF read points

Due to their comparatively large effective range, RFID UHF systems (frequency band 865 928 MHz) have different requirements in terms of planning, commissioning and operation compared with the HF systems commonly used up to now in automation (frequency band

13.56 MHz). This section describes important rules for preparation and implementation of the

RFID UHF systems.

4.6.1 Technical basics

General

In contrast to inductively coupled HF systems, in UHF technology, there is full propagation of the radio waves just as in other wireless systems (radio, TV etc). There are both magnetic and electrical field components present. The following graphic shows the structure of a UHF system. One characteristic is the design of the transponder that differs greatly from the structure used in HF systems, e.g. the use of a dipole or helix antenna.

Figure 4-11 Structure of a UHF RFID system

RSSI value

The signal strength of the transponder response is known as the RSSI value (Received Signal Strength Indicator). The RSSI value is a one byte value (0 to 255), the higher the value the better the signal strength (according to the IEEE 802.11 standard).

The actual RSSI value depends on numerous parameters:

● transponder type used,

● chip used in the transponder,

● connected antenna,

● transmit power,

4.6 Planning and installation of UHF read points

● distance between antenna and transponder,

● reflections,

● noise level in the channel used and in neighboring channels

The RSSI value is important for the automatic evaluation of the read point and for filtering. A simple comparison of the RSSI values of two transponders is nevertheless not possible because the values are influenced by the transponder tolerances and the non-homogeneous antenna field. This means that it is possible that a transponder positioned closer to the RFID antenna has a lower RSSI value than a transponder much further away.

Propagation of the antenna field

The waves do not propagate as a homogeneous field, there is superposition of the waves that can cause the following effects:

● Overshoots and field gaps due to obliteration of two waves

These are caused by reflection and the resulting propagation on different paths (comparable with fading effects on the car radio, e.g. noise when the vehicle is standing)

● Generation of overshoots due to reflecting objects and surfaces

This can be illustrated by comparing it with a "hall of mirrors". The signal transmitted by the reader is reflected (several times) by metallic objects such as housings, steel supports or grilles and this can lead to unwanted effects and read errors. Is also possible that a transponder is not identified although it is located in the assumed direct identification range of the reader. It can also happen that a transponder moving outside the antenna field is read out due to overshoots.

4.6 Planning and installation of UHF read points

Properties of the transmitting antenna

Depending on their design, UHF RFID antennas provide different properties. They differ in the polarization and antenna gain.

The direction of the electrical field component of an electromagnetic wave and the alignment of the antenna decide the polarization of the radiation. A distinction is made between linear and circular polarization of an antenna. With linear polarization you achieve the maximum write/read distances when the polarization axes of the antenna and transponder are parallel to each other. As the deviation increases, the received power deteriorates.

Figure 4-13 Effect of the polarization axes on the write/read distance with linear antennas

Linear antennas can only be used if the alignment of the transponder is defined. On the other hand, one advantage of linear antennas is that they react less sensitively to reflections. This restriction does not apply with circular polarization. Circular antennas can also be used with differing alignments of the transponder and achieve constant results (e.g. RF680A or RF685R). It has been shown that with a defined transponder alignment, the linear antenna normally produces the best results.

4.6.2 Implementation of UHF RFID installations

The use of UHF RFID systems requires careful planning and preparation to avoid problems during commissioning and operation.

4.6 Planning and installation of UHF read points

4.6.2.1 Preparation phase

Device selection

When selecting the suitable RFID hardware, remember the following minimum criteria:

● Integration in a control/IT environment

● Degree of protection

● Size of the identification range

● Type, number and position of the transponders in the antenna field

● Reflecting and absorbent materials in the vicinity of the antenna

● Distance between the antenna or the reader and the transponder

The following application examples illustrate the requirements for specific use cases and provide suitable solutions:

● Read point in a conveyor system in confined installation conditions:

A container should be transported in a conveyor system. Information on the next transport section is contained in a transponder which is attached to the side of the container.

Possible configuration: RF615R with integrated internal antenna and a compact external antenna (e.g. RF615A, RF620A)

● RFID gate at the incoming goods / outgoing goods department:

Several transponders are located on different packaging of products on a pallet. These need to be identified when passing through the RFID gate.

Possible configuration: RF650R with four circular antennas (e.g. RF650A, RF660A depending on the required radiated power)

● Four read points along the production line:

A product needs to be processed by different machines along the production line. The information for this is contained on a transponder attached to the product that must be read out at each machine.

Possible configuration: RF680R with four antennas (e.g. RF615A, RF620A, RF680A)

● Read point on a production line with a predominantly metallic environment:

A product needs to be processed by different machines along the production line. The information for this is contained on a transponder attached to the product that must be read out at each machine.

Possible configuration: RF685R with integrated adaptive antenna

RF600 system planning

4.6 Planning and installation of UHF read points

Dynamic identification

Dead spots cannot be excluded. To be able to compensate for dead spots, we recommend that you give preference to dynamic identification rather than static identification. Dynamic identification means that the transponders are read while they are moving (e.g. on the conveyor belt). If static identification is necessary, the antenna field can e virtually dynamized with the RF685R antenna or RF680A.

Triggering

To read out all right transponder data, you can have the readers perform permanent write/read actions or have specific write/read actions triggered. For the following reasons, we recommend that you trigger specific write/read actions:

● The RFID system only performs write/read actions when an object to be identified enters the antenna field. This reduces the number of process errors and they can be identified more quickly.

● Due to the fact that the various RFID systems only perform write/read actions when necessary, this reduces the possibility of antenna fields disrupting each other. This increases process reliability in plants, particularly when there is a high reader density.

Decoupling third-party RFID systems

If you are using different RFID systems, make sure that no two systems are active at the same time or operate separately from each other. Ideally there should be no mixed usage.

Training

Make sure that the engineers commissioning the UHF RFID systems are adequately trained.

4.6.2.2 Test phase

Metals and absorbent materials have a major influence on the functioning of UHF RFID systems. Since every environment has different conditions, we recommend that you run a test with all the objects to be identified for each read point. Include neighboring readers in these tests as well as scenarios for overshoots. Run through the tests an adequate number of times to make sure that any sporadically occurring influences on the antenna fields are also tested.

The final position of the transponder should only be decided after an adequately intensive test phase so that suitable variations can be tried out if errors occur.

4.6.2.3 Setting up read points

The read point setup described in this section is performed using the Web Based Management (WBM) and applies to the RF600 readers. You can find a detailed description of the WBM in the configuration manual "SIMATIC RF600 (https://support.industry.siemens.com/cs/ww/en/ps/15081/man

4.6.3 Dealing with field disturbances

4.6.3.1 Types and approaches to solutions

The superposition of radio waves and reflection by conductive materials (in particular metal) can lead to weakening or strengthening of the antenna field at certain points in space. These effects can lead to disruptions when identifying RFID transponders that can be distinguished as follows:

● Overshoots due to increasing field strength: Transponders are detected that are actually beyond the read distance.

Approaches to solutions:

– Reduction of the radiated power

– Determining the input attenuation

– Use of UHF algorithms

– Changing the antenna position

– Shielding measures

– Varying the antenna polarization

– Use antennas with a lower gain

– Use antennas with adjustable polarization

● Lack of separation of transponders: Transponders positioned close together are detected together although the application logic requires individual detection (for example to determine the positioning order). All transponders are within the read distance.

Approaches to solutions:

– Reduction of the radiated power

– Use of UHF algorithms

– Changing the antenna position

– Shielding measures

– Use antennas with a lower gain

● Field obliteration: Due to the superposition of waves, obliteration effects occur within the read distance.

Approaches to solutions:

– Varying the antenna polarization

– Using additional antennas

– Use of UHF algorithms

– Changing the antenna position

– Shielding measures

– Use antennas with a lower gain

Note Occurrence of disturbances

Remember that these disturbances can also occur sporadically or in certain comb

4.6 Planning and installation of UHF read points

● Reader ↔ reader influence: Several readers influence or disturb each other during

transponder identification.

Approaches to solutions:

– "Interconnect" neighboring readers so that they do not send at the same time

– Enable intermissions ("Settings - General" menu item)

– Channel management

● Reader ↔ transponder influence: A reader communicates with a transponder that is also

in the identification area of another reader.

Solution approaches:

– "Interconnect" neighboring readers so that they do not send at the same time

● Other sources of disturbances that can lead to restriction of transponder identification.

Other sources of disturbances can occur if there are devices with similar frequency bands (for example 900 MHz) in the vicinity of the reader. The diagnostics corresponds to the influence of one reader on another. Mobile phones can also disturb identification. This is the case if a reader of the type FCC or CMIIT is operated in Europe.

Solution approaches:

– The disturbances can be eliminated by temporarily turning off the suspected source of

interference or its shielding. Interference can also occur with devices in other frequency bands if these are located in the immediate vicinity of the RFID antenna (e.g. DECT telephone directly in front of the RFID antenna). Common industrial interference mechanisms, such as the harmonics of frequency converters or static discharge (ESD) can also cause disturbances.

4.6.3.2 Measures for eliminating field disturbances

Using shields

To avoid reflections, you can fit UHF absorbent material. To do this, the absorbent material is mounted at various suspected reflection points until the field disturbance no longer occurs. Where possible, avoid the use of metal structures (for example housings) and use plastic instead.

inations.

Even with reader-to-reader influence, you can use absorbent plates or shielding sheets.

4.6 Planning and installation of UHF read points

Channel management

To operate the readers, depending on the country profile, you have between four and fifty send channels available. Ideally, you should make the channel assignments manually in STEP 7 Basic / Professional (TIA Portal) or in the WBM. This allows you to reduce reader-to reader influence and if applicable field obliteration.

Table 4- 4 Example of a channel plan according to ETSI

Transmission

Frequency (MHz)

Use of multiple antennas

If you do not find the ideal antenna position to be able to identify the transponders in the various positions and alignments, you have the option of using more antennas. Multiple antennas mounted at different positions enlarge the identification range.

Enabling send pauses

If too many neighboring readers send at the same time, this causes overload of the radio channels. In this case, enable the "Intermissions" function in the "Settings - General" menu item to improve read reliability.

Varying the antenna polarization

By using linear or circular antennas, you can reduce field obliteration. This improves the reader reliability in difficult radio conditions.

The RF685R and RF680 readers also provide the option of operating the internal or external antenna both as a linear, vertical, linear horizontal and circular antenna. If more than one polarization is enabled, the polarization is changed automatically with each inventory. This increases the probability of identification in difficult radio conditions.

865.7 866.9 866.3 867.5 865.7 ...

Changing the antenna position

In difficult radio conditions (e.g. where there is a lot of metal) it is possible that the communication between transponders and readers is impaired. You can counter this by changing the position of the antenna relative to the transponder. This also changes the multipath propagation of the radio waves and obliteration is reduced or shifted.

Use of UHF algorithms

In the "Settings - Read points" menu item of the WBM, you will find various "Tools" in the "Algorithms" area that you can use to improve the read/write reliability.

4.9 Guidelines for electromagnetic compatibility (EMC)

4.9.1 Overview

These EMC directives answer the following questions:

● Why are EMC directives necessary?

● What types of external interference have an impact on the system?

● How can interference be prevented?

● How can interference be eliminated?

● Examples of interference-free plant design

)

The description is aimed at "qualified personnel":

● Configuration engineers and planners who plan system configurations with RFID modules and have to observe the necessary guidelines.

● Installation 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.

4.9 Guidelines for electromagnetic compatibility (EMC)

4.9.2 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:

● Internal immunity to interference:

Immunity to internal (own) electrical disturbance

● External immunity to interference:

Immunity to external electromagnetic disturbances

● 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 RED directives. 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 directives 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.

RF600 system planning

4.9 Guidelines for electromagnetic compatibility (EMC)

4.9.3 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

● Plan a meshed grounding concept.

● 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.

SIMATIC RF600

88 System Manual, 11/2018, J31069-D0171-U001-A21-7618

RF600 system planning

4.9 Guidelines for electromagnetic compatibility (EMC)

● 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.

4.9.4 Propagation of electromagnetic interference

Three components have to be present for interference to occur in a system:

● Interference source

● Coupling path

● Interference sink

Figure 4-16 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.

4.9.5 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.

Replace the power supply

Better cable shielding

Ground the reader

• Position the antennas further apart.

• Erect suitable damping materials between the antennas.

• Reduce the power of the readers.

Please follow the instructions in the section

Proper equipotential bonding is thus essential.

● The equipotential bonding conductor must have a sufficiently large cross section (at least

10 mm

● 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.

SIMATIC RF600 System Manual, 11/2018, J31069-D0171-U001-A21-7618

RF600 system planning

4.9 Guidelines for electromagnetic compatibility (EMC)

Figure 4-17 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 contact voltages in the event of equipment faults whereas equipotential bonding prevents the occurrence of differences in potential.

4.9.6 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.

The following generally applies:

● For analog signal cables, the shield has to be connected at one end on the receiver side

● For digital signals, the shield has to 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

4.9 Guidelines for electromagnetic compatibility (EMC)

Figure 4-18 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.

Figure 4-19 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.

4.9 Guidelines for electromagnetic compatibility (EMC)

Figure 4-20 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.
