Introduction – MOBY U

MOBY U is the RF identification system which is especially designed for
long–range applications in industry and logistics. It uses the transmission
frequency in the ISM frequency band of 2.4 GHz in the UHF range (ultra
high frequency). This ISM frequency band is recognized around the world. It
unites the power of innovative HF technologies and, at the same time, ensur­es continuity at the customer’s by being almost totally compatible with the
proven MOBY I system. Robust housing and power-saving circuiting
technology give you years of maintenance-free operation even under the
most rugged of industrial conditions.

MOBY U covers all transmission ranges up to three meters which means that
it meets the prerequisites for a transparent identification solution in the auto­motive industry, for instance. It offers the communication distances (much
longer than one meter) required to design optimized working processes and
ensure necessary safety zones during automobile production.

The transmission frequency and the robust modulation not only give you
transmission ranges of several meters but also ensure sufficient distance to
the typical sources of electromagnetic interference in industrial production
plants. With MOBY U, you can forget the old sources of interference such as
welding devices and power switches, pulsed DC drives and switching power
packs and all the time–consuming interference suppression measures which
were needed.
Familiar sources of interference during UHF transmission such as reflection,
interference and over–ranging are handled with appropriate technical mea­sures on the MOBY U. In addition, special coding procedures ensure that
data transmission is correct and data integrity is preserved. Proven methods
and algorithms of mobile radio technology (GSM, UMTS) have been used for
this purpose by the identification system. Specially designed antennas ensure
a homogenous transmission field so that the mobile data memories (MDSs)
are detected reliably even in difficult locations.

2

Conflicts with other users of the 2.4 GHz frequency band are avoided by us­ing very low sending power (less than 50 mV per meter at 3-m intervals) and
automatic selection of free and interference-free frequency channels.

With its 32–Kbyte mobile data memories (MDS U524 and MDS U589 – up
to +220 °C cyclically), MOBY U offers a transparent solution for the auto­motive industry.

Like the MDSs of MOBY U, UHF transponders with selective read/write
functions always require their own energy (battery) for data communication.
This power–saving circuiting technology guarantees years of maintenance–
free service.

Introduction – MOBY U

Simple and flexible installation of the read/write devices (SLGs) and the mo­bile data memories (MDSs) in particular are two common requirements of all
assembly and production lines.

The SLG U92 offers easy system integration via coupling to:

 Reliable MOBY interface modules (ASMs) for PROFIBUS-DPV1 and

SIMATIC S7
– ASM 452
– ASM 473
– ASM 475

 Directly on a standard PC, SICOMP or PC–PLC

Software tools such as SIMATIC S7 functions (FC) and C library MOBY API
for applications under Windows 98/2000/NT make implementation in specif­ic applications easy.

As with the other MOBY identification systems, the MDSs can be operated
with direct byte addressing or with the filehandler.

The convenient and powerful filehandler of MOBY I with its file addressing
is directly integrated on the SLG U92 with expanded functions. The MOVE
and LOAD commands of the MOBY I filehandler are a thing of the past. The
SLG always fetches the file management information it needs directly from
the MDS.

MOBY U can be used in three different ways.

1. For existing system solutions with MOBY I compatibility (no
bunch/multitag)

– MOBY U with standard settings
– Range of up to 1.5 m (fixed setting)
– Byte addressing via absolute addresses
– Filehandler: With unmodified functions and without MOVE and

LOAD commands

2. For existing system solutions with MOBY I compatibility
plus expansions (no bunch/multitag)

– Just a few expanded commands for changing the standard settings and

requesting diagnostic data

– Range up to 3 m (to be limited in increments)

3. Full use of MOBY U performance (with bunch/multitag)

– Commands and/or user data with clear allocation due to the MDS

number for bunch/multitag

– Range up to 3 m (to be limited in increments)

Introduction – MOBY U

With MOBY U, a service and diagnostic interface is installed directly on the
read/write device (SLG) to make commissioning easier. Not only current
transmission parameters can be analysed here but data communication can
also be logged. Additional statistical functions are available for quantitative
and qualitative evaluation of data communication.

Primary
applications

3.1 The Fundamentals

MOBY U is a UHF system with powerful features. This makes it much easier
to configure and handle the system.

 The range (read/write distance) and communication speed are the same

for all data carriers. However, they do differ in memory size, operational
temperature and lifespan.

 Reliable communication due to a homogenous transmission field with

circular polarization in dynamic and static operation. There is no fading
(i.e., temporary ”holes” in the field).

 The range (0.15 m to 3 m) permits use throughout production.
 The range of the transmission field can be limited (in increments) from

0.5 m to 3 m. This limitation prevents over–ranging and the communica­tion range is clearly specified.

 Familiar sources of interference during UHF transmissions such as reflec-

tion and interference have been removed with appropriate technical mea­sures.

 Due to the transmission frequency and the robust modulation procedures,

electromagnetic sources of interference can be disregarded.

 Simple and flexible installation and customized system integration with

standard hardware and standard function blocks make commissioning fast
and easy.

 The robust housing and the power–saving circuiting technology make for

years of maintenance–free operation even under the most rugged of pro­duction environments.

 Conflicts with other users of the 2.4 GHz frequency band are avoided by

using very low sending power (less than 50 mV per meter at 3-m inter­vals) and automatic selection of free and interference–free frequency
channels.

Optimum utilization does require adherence to certain criteria.

 Transmission window
 Time that MDS is in the field (speed and amount of data) during dynamic

transmission

 Metal–free space and metallic environment around MDS and SLG
 Ambient conditions such as humidity, temperature, chemicals, and so on
 Other users of the frequency band at 2.4 GHz
 Readiness to communicate: Sleep-time, standby mode, antenna on/off
 Bunch size for bunch/multitag
 System interface performance
 SLG synchronization
 Proximity switches

3.1.1 Transmission Window

MOBY U is a UHF system. UHF systems have a relatively wide range de­spite their low emission power. However, the emission field has a directional
characteristic which depends on the antenna construction. MOBY U has vari­ous function zones which depend on direction and distance to keep the
MDS’s power requirements low and to make localization reproducible. The
states and reactions of the affected components vary with the three different
zones of the transmission field (see figure 3-1).

 Zone 3:

In simplified terms, zone 3 is the UHF–free area. The MDS is asleep and
only wakes up once every < 0.5 sec to listen for an SLG. Power consump­tion is very low. If other UHF users are in the vicinity and they are using
the same frequency range, this does not shorten the battery life of the
MDS since it does not wake up until it receives a special code.

3-3

Configuration and Installation Guidelines

 Zone 2:

If the MDS receives this special code in the vicinity of an active SLG, it
enters zone 2 (see figure 3-1). Starting immediately it accepts the SLG
and responds briefly with its own ID. However, the SLG ignores all
MDSs which are not in zone 1 (radius can be parameterized on the SLG
in increments). Power consumption in zone 2 is a little higher than in
zone 3.

 Zone 1:

When an MDS enters zone 1, it is registered by the SLG and can begin
exchanging data. All read and write functions can now be performed. The
power consumption of the MDS increases briefly during communication.
Since transmission through the air is very fast, total communication time
is very short. The entire 32–Kbyte data memory can be read in less than
four seconds. This means that data communication hardly uses the bat­tery.
As long as the MDS is located in zone 1, it is ready to exchange data
when requested by the SLG. When no command for the MDS is queued,
it still reports at regular parameterizable intervals with its ID when re­quested by the SLG. Its behavior corresponds to that of zone 2. Current
consumption drops again accordingly.

General
configuration rules

 With MOBY U as a UHF system, the following physical characteristics

must be considered when you configure the system.

 The waves in the UHF range spread out in straight lines.
 The transmission field (zones 1 and 2) is shaped like an ellipse.
 The range of the transmission ellipse up to 3 m can be adjusted in incre-

ments for better identification of the MDS.

 In simplified terms, the transmission field can be thought of as a cone and

the midpoint of the antenna is located at the peak of this cone. The angle
of opening is approx. 90°. A primarily homogenous field is then assumed
within this parameterized area. Fading (temporary ”holes” in the field) in
this area is offset by technical measures.

 Ideally the MDS should penetrate the transmission cone of its basic sur-

face and exit through the surface area so that the MDS remains as long as
possible in the defined recording field.

 Since metallic surfaces reflect the waves, they can also be used for shield-

ing or even deflection. Particularly in typical production environments,
the wealth of metallic objects ensures a relatively uniform dispersion of
the transmission waves.

 For optimum data communication, metal should be avoided at least in the

vicinity of the vertical waves.

3-4

 Both the MDS and the SLG can be mounted directly on metal.

3.3.2 General

Configuration and Installation Guidelines

Increasing use of electrical and electronic devices creates the following situa­tion.

 Increasing density of the components
 Increasing power electronics
 Increasing switching speeds
 Lower power consumption of the components

The more automation, the greater the danger of the devices interfering with
each other.
Electromagnetic compatibility (EMC) means the ability of an electrical or
electronic device to function correctly in an electromagnetic environment
without bothering its surroundings up to a certain degree.

EMC can be divided into three areas.

 Own interference immunity

Immunity against internal (i.e., own) electrical interference

 Free interference immunity

Immunity against outside electromagnetic interference

 Degree of interference emission

Interference emission and influence of the electrical environment

All three areas must be considered when checking an electrical device.
The MOBY modules are checked for adherence to certain limit values. Since

the MOBY modules are only part of a total system and sources of interfer­ence can be created just by combining different components, the setup of a
plant must adhere to certain guidelines.

EMC measures usually comprise a whole package of measures which must
all be taken to obtain an interference–immune plant.

Note

 The constructor of the plant is responsible for adherence to the EMC

guidelines whereas the operator of the plant is responsible for radio inter­ference suppression for the entire system.

 All measures taken while the plant is being set up prevent expensive

modifications and removal of interference later on.

 Naturally, the country–specific rules and regulations must be adhered to.

They are not part of this documentation.

3.3.3 Spreading of Interference

The following three components must be present before interference can oc­cur in a plant.

 Source of interference
 Coupling path
 Potentially susceptible equipment

Source of interference
(instigator)

Example: Drive

Figure 3-2 Spreading of interference

Coupling path

Example: MOBY cable

Potential susceptible
equipment
(malfunctioning device)

Example: ASM 452

If one of these components is missing (e.g., the coupling path between inter­ference source and potentially susceptible equipment), the susceptible device
is not affected even when the source is emitting strong interference.

EMC measures affect all three components to prevent malfunctions caused
by interference. When setting up a plant, the constructor must take all pos­sible precautions to prevent the creation of interference.

 Only devices which meet limit value class A of VDE 0871 may be used

in a plant.

 All interference–producing devices must be corrected. This includes all

coils and windings.

 The cabinet must be designed to prevent mutual interference of the indi-

vidual components or keep this as low as possible.

 Precautions must be taken to eliminate external interference.

The next few sections give you tips and hints on good plant setup.

3.3.4 Cabinet Layout

User responsibility for the configuration of an interference–immune plant
covers cabinet layout, cable installation, grounding connections and correct
shielding of the cables.

Note

Information on EMC–proof cabinet layout can be taken from the setup
guidelines of the SIMATIC controller.

Configuration and Installation Guidelines

Shielding by
housing

Magnetic and electrical fields as well as electromagnetic waves can be kept
away from susceptible equipment by providing a metallic housing. The better
induced interference current is able to flow, the weaker the interference field
becomes. For this reason all housing plates or plates in the cabinet must be
connected with each other and good conductivity ensured.

Figure 3-4 Shielding by the housing

When the plates of the switching cabinet are insulated against each other, this
may create a high–frequency–conducting connection with ribbon cables and
high–frequency terminals or HF conductive paste. The larger the connection
surface, the better the high–frequency conductivity. Connection of simple
wires cannot handle this task.

Configuration and Installation Guidelines

Avoidance of
interference with
optimized layout

Installation of SIMATIC controllers on conductive mounting plates (not
painted) is a good way to get rid of interference. Adhering to the guidelines
when laying out the switching cabinet is a simple way to avoid interference.
Power components (transformers, drives, load power packs) should not be
located in the same room with controller components (relay control parts,
SIMATIC S5).

The following principles apply.

1. The effects of interference decrease the greater the distance between
source of interference and susceptible equipment.

2. Interference can be decreased even more by installing shielding plates.

3. Power lines and high–voltage cables must be installed separately at least
10 cm away from signal lines.

Filtering the
voltage

Power filters can be used to combat external interference over the power
network. In addition to correct dimensioning, proper installation is very
important. It is essential that the power filter be mounted directly on the
cabinet leadin. This keeps interference current from entering the cabinet by
filtering it out from the beginning.

3.3.5 Avoiding Sources of Interference

Inclusion of interference sources in a plant must be avoided to achieve a
higher degree of interference immunity. All switched inductivity is frequent­ly a source of interference in plants.

Suppression of
inductivity

Relays, contactors, etc. generate interference voltages which must be
suppressed with one of the following circuits.

24 V coils create up to 800 V even with small relays and 220 V coils gener­ate interference voltages of several kV when the coil is switched. Free wheel­ing diodes or RC circuits can be used to prevent interference voltage and thus
also inductivity in lines which must be installed parallel to the coil line.

Note

All coils in the cabinet must be interference–suppressed. Don’t forget the
valves and motor brakes. A special check must be made for neon lamps in
the switching cabinet.

3.3.6 Equipotential Bonding

Differences in potential may be created between the parts of the plant by dif­fering layout of plant parts and differing voltage levels. When the parts of the
plant are connected with signal lines, equalizing currents flow over the signal
lines. These equalizing currents may distort the signals.

This makes it very important to provide correct equipotential bonding.

 The cross section of the equipotential bonding line must be large enough

(at least 10 mm2).

 The distance between signal cable and equipotential bonding line must be

as short as possible (effects of antenna).

 A fine–wire line must be used (better high–frequency conductivity).
 When the equipotential bonding lines are connected to the central equipo-

tential bonding rail, power components and non–power components must
be combined.

Figure 3-8 Equipotential bonding

The better the equipotential bonding in a plant, the less interference is
created by potential fluctuations.

Don’t confuse equipotential bonding with the protective ground of a plant.
Protective ground prevents the creation of high touch voltages on defective
devices.

3.3.7 Shielding the Cables

To suppress interference coupling in the signal cables, these cables must be
shielded.

The best shielding is achieved by installation in steel tubing. However, this is
only required when the signal line has to be led through high interference.
Use of cables with braided shields is usually sufficient. In both cases, correct
connection is decisive for shielding.

Note

A shield which is not connected or is not connected correctly is not a shield.

The following principles apply.

 With analog signals, the shield is connected on one side to the receiver

side.

 With digital signals, the shield is applied on both sides to the housing.
 Since interference signals are frequently in the HF range (> 10 kHz), a

large–surface shield which meets HF requirements is needed.

Figure 3-9 Shielding the cables

The shield bar must be connected (over a large surface for good conductivity)
to the switching cabinet housing. It must be located as close as possible to the
cable leadin. The cables are bared and then clamped to the shield bar (high–
frequency clamps) or bound with cable binders. Make sure that the connec­tion is very conductive.
