1.2 Definitions of Terms
Transponder
RFID Tag (mark) in/on the ground or mounted on moving parts, which is inductively
supplied with energy by the antenna and then with this energy sends his code at half
the frequency.
Posipulse
Also called middle signal, short for position impulse. With the position impulse the
time of crossing the reference axis can be transmitted by telegrams without time lag.
Energy coil
Coil whose generated alternating magnetic field supplies the transponder with en-
ergy. For some antennas, the code emitted by the transponder is also received via
this coil.
Nibble
A nibble (rarely called nybble or nyble) is a amount of data containing four bits; it is
also called a half byte (source: Wikipedia). The transponder code comprises 16 bits,
i.e. four nibbles. Thus four hexadecimal code digits can be represented.

8Chapter 2 – Introduction
Data transmission between various objects (tool carriers, tools, vehicles, etc.) and
the control system is crucial for ensuring the operating procedure. Movable objects
must be identified and positioned quickly and reliably. Thereby identification sys-
tems offer a safe, easy to install and economical solution. They can be used to man-
age and monitor processes.
Such a system is suitable for almost all areas in which production and transportation
processes need to be automated. In order to implement this automation, incoming
data on transport route and destination, location and production status must be col-
lected and processed. Special advantages of the inductive identification system are
the millimeter-precise positioning, long rage identification and insensitivity to con-
tamination.
2.1 Variants
The transponder antenna is available in several versions.

2.4 Operating conditions
The following requirements apply to the use of the transponder antenna:
As shown in Figure 12 on page 24, the antenna can be installed upright or
crosswise on the vehicle. The shielded rear side may not point towards the tran-
sponder, see Figure 11 on page 24.
The antenna can be installed with its back directly on metal.
Things that can interfere with the antenna: Conductive materials, conductor
loops and reinforcements in the reading area of the antennas or near the tran-
sponder (see transponder data sheet). Interfering signals from clocked drives
and their power supply cables must be avoided (see section 4.3 on page 24).
Between two transponder antennas there has to be a minimum distance of
1500 mm. With some antenna variants, this can be circumvented by temporar-
ily deactivating individual antennas via the data interface, see Table 2 on page 8.
Between two transponders there has to be a minimum distance of 500 mm.
There may always be at most one transponder within the reading area of the
antenna.
When changing the direction of travel, incorrect PosiPulses can occur as a mat-
ter of the principle. Changes of direction should therefore be avoided in the sys-
tem or compensated in the evaluation. For this purpose e.g. a PosiPulse delete
command can be given via the data interface. You can see which variants sup-
port this in Table 2 on page 8.
When used in systems with inductive power transmission (only antenna vari-
ants with 409 kHz can be used here), a minimum lateral distance of 200 mm
must be maintained from the wires of the energy line, the power electronics
and the connecting lines of the pickups, see section 4.3.2 on page 25.
2.5 Application Examples for the Automation
Automation can be performed for:
Warehousing / production lines / material flow control systems
Location determination of vehicles and containers

2.6 System Layout
The transponder antenna is usually mounted under a vehicle and connected to the
vehicle computer (e. g. a PLC), which evaluates the PosiPulse and the transponder
code. The corresponding transponders are installed in or on the floor. See the follow-
ing sections for the operating principle.
Figure 1 Block diagram system layout (example)
2.7 Functional Description
2.7.1 General Functional Description
The transponder antenna is used in identification systems with positioning. It out-
puts the transponder code and a position impulse (PosiPulse) of 100 ms duration
when the transponder crosses the center of the antenna (see below). This enables
the detection of exactly defined positions.
As soon as a transponder is within the reading area of the antenna, it is supplied in-
ductively with energy by the energy coil without contact and then cyclically sends
its code back to the antenna. Otherwise, the transponder is completely passive and
does not require a power supply or battery. Only one transponder at a time is allowed
in the reading area of the antenna.
The transponder code can be reprogrammed via the antenna for compatible read/
write transponders (see Table 3 on page 9).
If several antennas are expected to operate simultaneously, the necessary mini-
mum distance must be observed (see section 2.4 on page 10).

2.7.2 Scope and Function
The positioning occurs according to the field compensation method. Centrically to
the antenna the measured field for the transponder is erased, resulting in the data-
free area D, which has a width of 25 to 30 mm at the nominal reading distance S and
in which no telegrams are output, see Figure 2 below.
The field strength of the alternating magnetic field decreases with increasing dis-
tance between transponder and reading antenna. The exchange of information is
therefore only possible within the detection areas 1 and 2 (Figure 2). Viewed from
above, the detection areas are limited by the field length L and the field width B, see
Figure 3.
Figure 2 Detection area 1 and 2, data-free area D and nominal reading distance S, side view
Figure 3 Detection areas, top view
For some antenna variants, individual antennas can temporarily be deactivated via
the data interface. This can be used, for example, if the antennas do not necessar-
ily have to be used at the same time – e.g. if one is used to detect transponders in
longitudinal direction, while the other is used for lateral driving. Table 2 on page 8
shows which variants support the deactivation.

Introduction – Chapter 2
Figure 4 Core area of the reading antenna with positioning pulse (top view)
The code of the transponder is read in both detection areas. For an additional Posi-
Pulse to be triggered, the transponder must first have moved through area 1. The
maximum lateral offset to the antenna center is determined by line C. In this case,
the PosiPulse is generated as soon as the transponder reaches the crossing to the
data-free area D. Since both detection areas have a curved course, the point at
which a PosiPulse is triggered shifts the further away the transponder is from the
center of the antenna (line A) (center deviation). The absolute values are given in Ta-
ble 76 on page 67. In area 2 the DATA LED lights up, in area 1 also the LED CD.
Only a maximum of one transponder is allowed in the detection area of the
antenna at all times! The following image shows several transponders to explain
the different transponder positions.

2.7.3 Signals and Timing
Figure 5 Signals and Timing
At first the data is „uncertain“ and the signal strength is still low (area 2). When ap-
proaching further the signals of the data become stronger and can be read com-
pletely. Finally, the inner detection area (area 1) is reached. Leaving the detection
area is detected by decreasing of the thresholds (3 and 4).
Crossing the field boundary triggers the PosiPulse (center signal). By passing
through the next detection areas (5 to 8) the data is read and displayed again. At the
field boundary at point 8 no center signal is triggered now. The centre signal is also
not set if the vehicle stops and drives back in the detection gab (4 and 5) after pass-
ing through points 1 to 4. The PosiPulse is only emitted again for this transponder if
in the meantime another transponder with a new code has been read or – depend-
ing on the variant, see Table 2 on page 8 – a PosiPulse delete command (= delete
last transponder code) has been sent via the data interface.
If a vehicle stops before the PosiPulse is triggered and changes direction, a
„wrong“ center pulse is generated at position 1 or 8. These positions are not
exactly definable. The identification system should therefore only be used
in systems without change of direction.
If data errors are generated by interference signals in areas 2 and 3 (or 6 and 7), a
positioning impulse is accordingly generated at the wrong position!

Hardware – Chapter 3
3.1 Transponder
The Götting transponders listed in Table 3 on page 9 are used as reference marks in
the ground. The transponder code consists of 16 bits.
3.2 Transponder Antenna (Variants)
3.2.1 Applies to all Variants
The antenna system is located in a 156.5 x 31 x 53 mm (L x D x H) housing made
out of PC (polycarbonate). Depending on the variant, the height including connec-
tors is max. 70 mm.
3.2.1.1 Switch-On Behavior
After applying the supply voltage, the positioning output PosiPulse is active for the
duration of the reset (approx. 500 ms). To check their function, all LEDs are switched
on for 500 ms, respectively. After approx. 2 s the device is ready for operation.
3.2.1.2 Switch-Off Behavior
The behavior of the PosiPulse output during switch-off is random. Levels of unde-
fined height up to max. +Ub can occur until the voltage in the device has completely
dropped. These levels can be falsely processed as positioning pulses by the down-
stream evaluation/control system.
3.2.1.3 Code Output
The code transmitted by the transponder consists of a sequence of 24 bits in which
16 bits are encoded. These are output via the respective interface. Transponders can
also be programmed via the antenna, see chapter 10 on page 59.
3.2.1.4 PosiPulse
The transponder antenna provides an output for the PosiPulse via ST 1 in all variants.
The positioning pulse is triggered at center crossing of the antenna. Its duration is
100 ms. When activated, +Ub with a current limitation of 20 mA is switched on the
corresponding output (not electrically isolated). For the sequence of a transponder
crossing and the triggering of the PosiPulse see section 2.7.3 „Signals and Timing“
auf Seite 14.
If, for example, a +Ub voltage output is desired, contact 2 can be connected to GND
via a resistor of 1 KOhm, as shown in the following picture.
Hardware
The subsequent evaluation must be adapted so that it ignores PosiPulses when
the antenna is switched off.
