2.1.3 Total communication time
Point-to-point connection
The total time required for communication between
the host system and the Data Tag is calculated by
adding the Data Tag communication time (Table
2.a) to the host communication time (Table 2.b).
This will result in a total communication time based
on the following conditions:
Example
Let’s assume initial production requirements are to
be written to a PC 3105/00D Data Tag at the start
of a production line. The Data Tag is present
(moving or stationary) in the communication zone
for 10 seconds. 30 files with an average size of 100
bytes are to be written. The host communication
baudrate can be chosen to satisfy the time
requirements. The OIS-P is connected to the host
in a point-to-point configuration and the response
time for the host is less than 10 ms.
The host has a response time of 10 ms.
The OIS-P system is connected to the host
in point-to-point connection.
Time required

If the serial interface response time in the host is

additional time will have to be added three times.

Multidrop connection
In case OIS-P communicators are connected in a
multidrop configuration, the following guidelines will
apply for determining the total time required for
moving data between Data Tag and host:

If each Communicator’s task is performed
from start to finish, without delay due to host
communication with other units, the total time
required for moving data between Data Tag
and host will be the same as for a point-topoint connected unit.
However, if the system engineer designs the
application software program in a way, that
the process of moving data between Data
Tag and host may be interrupted by host
communication with other Communicators,
an object must remain in front of an antenna
for a longer time than in a point-to-point
situation.
Total:
Example on total communication time.
Result:
The baudrate 19200 should be used for sufficient
margins. A faster solution would be to use the
command buffer. All data can be loaded into one
buffer before the Data Tag arrives to the
communication zone.
With a command buffer containing CO (Copy Buffer
to Buffer) and LD (Load) there is no need for a
communication to the host for every file.
The resulting time in the example above would be
less than 5.0 s., i.e. a recommendable margin of a
factor 2.
How much longer this required time will be,
depends on how the system engineer has
designed the application specific software in
the host.

2.3 Distance between Data Tags
Narrow antenna field
The data transmission frequency of 2,45 GHz
offers many excellent characteristics, of which one
is the ability to “focus” the microwaves on a desired
area, much like a flash light throws out a narrow
beam of light.
Figure 2.4
Focussing on the “right” object thanks to the narrow antenna field.
Data Tag ID-address
Distance between Data Tags
To further enhance installation flexibility and ensure
optimum communication reliability, each Data Tag
has a unique identity. The so called ID-address is
factory programmed from a range of more than 16
million (224) ID-addresses. The unique IDaddresses will ensure that communication initiated
with an Data Tag also can be finalized with the that
particular Data Tag, even if another Data Tag
would come in closer to the antenna. It is thus
important that the ID-addresses remain unique
even if the user reinitialises the tags. The system
is, however, basically designed for one tag in the
lobe and other situations should be avoided.
It is important that the Data Tag with which
communication is to be established, returns the
strongest signal to the antenna, as the Data Tag
communication is initiated by OD or user
command. To translate that into a minimum
distance between Data Tags, an antenna lobe
diagram must be studied.
OIS-P, PC3141/03 Manual
The graph lines in figures 2.1 and 2.2 represent
positions of similar signal strength in front of an
antenna. The distance between two graph lines
represent a signal strength difference of 3 dB.
Baumer Ident
17
System performance
The recommendations for how close Data Tags
may be to each other at a communication point are:
1. Ensure at least a 3 dB difference in signal
strength between the intended Data Tag and all
other Data Tags, when communication starts. If
a major difference in Data Tag exposure to
foreign substances like paint etc can be
expected, this difference should be added to the
3 dB mentioned above. Please refer to section
3.3.
2. The closer to each other the Data Tags must
come, the shorter the communication distance
should be. By reducing the communication
distance, it is easier to maintain a significant
difference in signal strength between the
intended Data Tag straight in front of the
antenna and not intended Data Tags.
The closer Data Tags come to each other, the
more important also the timing of object detect
activation becomes. If objects come very close
to each other, OD should be activated as the
correct Data Tag is located straight in front of the
antenna. This however means that part of the
theoretical access range is lost. For
communication with objects at standstill this
means that the object stop position is more
critical. For communica-tion with objects in
motion, it means that the available
communication time is reduced.
2.4 Distance between antennas
To ensure that the antenna only communicates
with the proper Data Tag the recommendations
under section 2.3 must be followed.
To avoid interference between adjacent antennas,
the Interlock function should be used. This means
that two or more antennas avoid to communicate
simultaneously. Since the microwave
communication time is short, this Interlock will
normally not influence the total communication time
notably.
An Interlock function can also be realised by
sequencing the commands in the host (PLC) to the
different control units. Without Interlock the
antennas should be separated 4–10 times the size
of the 0 dB graph line in figure 2.1 and 2.2.
If for some reason the Interlock function can't be
used there is a possibility to use frequency
separated antennas. Please contact your OIS-P
system specialist for advice.
3. Recommendation 1 and 2 above prevents that
no communication with other Data Tags will
occur, provided that the intended Data Tag is
present and in operating order. For a better
protection against communication with nearby
Data Tags, these cannot be allowed within an
area, corresponding to 2–5 times the size of the
0 dB graph line in figure 2.1 and 2.2.
Microwaves can, however, be influenced and
reflected by metal and directed into unwanted
areas, which has to be considered in the
installation layout.
Should this description not cover your installation
requirements or should you have any questions,
please consult your OIS-P system specialist for
advice.

3 Environmental influence
3.1 General
Since the OIS-P system is a vital part in a usually
complex production process, where products of
high value are manufactured, the highest priority
has been set on maximizing communication
reliability. This means that top performance must
be guaranteed even under severe industrial
environmental conditions.
industry, where the environment at times can be
testing; oils, water and other fluids have to be dealt
with, as has electromagnetic fields from welding
robots, paint layers, high temperatures, shock and
vibration and much more.
In the following, the potentially influencing
environmental factors and their consequences for
the installation planning is described.
The OIS-P technology has proven itself capable,
during more than a decade in the automotive
OIS-P, PC3141/03 Manual

Environmental influence
3.2 Metallic objects
Microwaves at 2.45 GHz have an excellent
capability of penetrating through foreign
substances, as described in section 3.3. However,
like all electromagnetic waves, microwaves cannot
penetrate through metallic objects.
Therefore, installations should be planned in such a
way that metallic objects are not present between
antenna and Data Tag when communication with
an Data Tag is to take place. However, small
metallic objects like metal shavings etc will not
influence negatively on the communication.
Further, both Antenna and Data Tags can be
mounted directly onto metal surfaces.
Any system operating in the MHz range or higher,
will have a communication range in which the
signal strength varies, due to wave reflections.
To minimize this phenomenon, the PC3100 system
features circular polarization, which suppresses
microwaves reflected from metal surfaces an odd
number of times. The suppression is equivalent to
6 dB or more.
A. Communication with the Data Tag is
performed in motion.
Any negative influence of reflections will result in
a slightly longer communication time. This
should be added to the communication time with
a margin dependent on the actual case, normally
a factor 2 (See section 2.1).
B. Communication is performed with the Data
Tag at standstill.
Metal surfaces in positions where they could
reflect microwaves from the antenna towards
the Data Tag should be studied. Generally they
should be at a position equivalent to a 6 dB
lower signal strength than the Data Tag, to
avoid negative influence. This can usually be
achieved by reducing the distance between
antenna and Data Tag.
Depending on reflections there may be points with
stronger or weaker signals and the position of the
antenna and/or the Data Tag should then be
adjusted to achieve a strong signal. The distance
between points with strong signal is normally 12.4
cm.
To avoid the risk of negative interference from
metal surfaces, one of the following situations
should be established.

Long term exposure of Data Tags to high
temperatures should generally be avoided, as can
be concluded from section 5.2.
The signal strength adjustment will
vary slightly, depending on the exact
composition of the contamination,
where it is applied etc.
Note 1: Layers beyond 1 mm not
likely. Adjustment for 0.2 mm
amounts to 0.5 dB.

How the recommended signal strength adjustment

3.4 Temperature
The antenna lobe diagrams in section 2 are valid
for temperatures up to +40 °C.
If the ambient temperature increases or if the Data
Tags are exposed to higher temperatures than +40
°C, this will result in a reduced signal strength and
a corresponding increase by reduction of the

The PC3141 system has been EMC-tested
according to the pr ETS 300339 which is required
for the CE-marking. This assures trouble-free
operation in demanding electromagnetical
environments.
Electromagnetic interference in cables
By selecting a suitable communication interface,
using specified cables and proper grounding,
optimum communication reliability is ensured.
Electromagnetic interference on the microwave
link
Industrial noise is typically present in the kHz and
low MHz frequency band. The OIS-P system is
only receptive for frequencies of 2,45 GHz +/- 5%,
so typical industrial noise will not affect the
microwave communication.

machines and fluorescent lighting fixtures may
produce short pulses around 2,45 GHz. However,
since the OIS-P system, if interfered, will continue

Environmental influence
communication from the point of interference,
rather than having to retransmit an entire message,
such short transients would merely increase the
required communication time by a small fraction.
If strong microwave fields from for instance
industrial microwave dryers can be suspected, an
on-site survey by a OIS-P specialist should be
carried out to determine proper installation
procedures.
3.6. Conclusions on environmental
influence
As shown, the OIS-P PC3141 system is highly
unsensitive to the typical industrial environment.
Still, common sense must be used when planning
an installation and some general rules of thumb
can be established.
1.
2.
It is recommended that installation is planned
in such a way, that communication at maximum specified distance and maximum
specified misalignment is avoided at the same
time. Thereby the access range becomes
longer, thus making object positioning less
critical and the communication capacity higher.
To establish if a reduction of the communication distance should be considered, the
following table will be of help. By adding the
recommended dB signal strength increase for
the factors that apply for your particular installation and comparing the total with diagrams in
section 2.2, a general understanding of a
suitable decrease in communication distance
is received.

Summary on environmental influence
on communication distance.
Electromagnetic interference and metal in the
communication area when reading in motion, will not
require a reduction of the communication distance.
This will only result in a slightly longer
communication time, which should be added to the
data from the table 2.1.
3. To finally define the optimum communication
distance, on-site testing is recommended. This is
especially important when there is plenty of metal
in the communication area and communicating is
performed at standstill, as table 3.c indicates.
On-site testing is facilitated by the installation
tools available.

4.1 Emitted power levels
The only emitted power worth mention is the
emission at the data transmission frequency 2,45
GHz. As can be seen from the graph below, the
emitted power is far below all known international
health standards.

Maintenance aspects
5 Maintenance aspects
5.1 General
5.2 Battery life
The PC3141 OIS-P system is basically a
maintenance-free system. Once correctly installed,
it will deliver many years of trouble-free operation.
General
In order to obtain communication distances in the
meter range, high data speed and still comply to
international telecommunications and health
standards, the Data Tags must be equipped with a
battery.
In important processes, the user usually collects
and evaluates communication reliability statistics
on a regular basis. These statistics can be
retrieved from the OIS-P communicator as
described in section 7.4 or can be collected at the
user control system level.
To get maximum life out of the batteries, the OIS-P
Data Tags are of semi-passive type. The majority
of the time, the Data Tags are passive and only
consuming a few µA. Only during communication,
which typically is ended in a fraction of a second,
will they be active with an increased current
consumption.
The batteries chosen are long-life lithium batteries,
whose life expectancy depend on the amount of
data communication, the data transmission speed
of the Data Tag and the ambient temperature in
which it is used. If the ambient temperature is high,
the battery life will be somewhat reduced. Long
term exposure to high temperatures should
therefore be avoided.
However, for most industrial applications, the
battery life will be longer than 6 to 8 years, as
specified on the Data Tag data sheets.
Battery-low alarm
The remaining battery capacity is automatically
monitored every time communication is established
with an Data Tag. When “battery-low” status is
reported to the user control system, the remaining
battery capacity is 5% and the Data Tag should be
taken out and receive a new battery.
Note:
OIS-P, PC3141/03 Manual
Baumer Ident
Battery low indication is not reliable
in sub-zero °C temperatures. If
battery-low indication is received in
temperatures below freezing, no
adequate conclusion can be made
from this.

7.3 PC program for
communication test
The PC3100 product range includes a menu driven
PC program for the EUROX_4 protocol PC 3100/
90A, (CMD3120) which allows communication with
the OIS-P system from an IBM compatible PC/XT/
AT personal computer, operating on DOS and having
at least one serial port, configurable as “COM1” or
“COM2”.
The program features three modes:
High level:
Commands can be issued in a very
simple way, such as “read file”, “write to file” etc.
Basic system functionality is easily executed, to
get acquainted with the system or for basic
installation testing.
Low level:
Commands are entered in low-level
language, exactly as they are described in the
Programmer’s Manual. The entire command list
can be executed, offering, for instance the
programmer, a hands-on possibility to get
acquanted with the full range of user commands
and command parameters.
Verifier level: Allows verification of execution
reliability for user-definable communication tasks.
The user can enter a sequence of low-level
commands including possible time-delays, to
resemble a typical communication task and
situation. The entered sequence is executed
repeatedly, when Object detect is indicated “active”
to the central unit. Communication reliability
statistics and measured execution
time (maximum, average and minimum) is
continously stored and displayed.
Successful microwave commands
Unsuccessful microwave commands
Successful microwave operations
Unsuccessful microwave operations
Definitions: Microwave commands are user
commands that request communication with an
Data Tag.
The execution of every microwave command
requires a number of microwave operations.
E Every unsuccessful microwave command
verifies that a user request for any reason was
not executed, i.e. a reading or a writing task was
not performed. An investigation of the Data Tag
and/or Communicator in question should be
undertaken.
E An unsuccessful microwave operation does
not verify that any communication between user
system and Data Tag has failed. It only states
that a greater number of microwave operations
that the theoretical minimum was needed to
execute the requested communication task. The
installation should however be made and
verified in such a way that the number of
unsuccessful microwave operations are as
insignificant as possible compared to the
successful ones. This way, a highly reliable
communication point is ensured.
The stored statistics will be erased as power to
the central unit is shut off. A new statistics count
will automatically start when the power is switched
on again.
7.4 Built-in communication
reliability statistics
The PC3141/03 central units have a built-in
statistics function, which keeps a count on the
system’s communication reliability. The statistics
count is initiated as soon as power is connected to
the system and a command is received.
34
These communication statistics are available by
connecting a VT100 (19200 baud, 7 bits, even
parity, one stopbit) compatible terminal to the
Terminal ports RS232 interface. The accumulated
status of four different communication parameters
is displayed simultaneously:
All counters are limited to 65 535 (then restart from
0).
