The transponder antenna HG G-71915ZA is designed to calculate the relative posi-
tion of matching RFID tags (transponders) and to output it to a higher-level control
system. Either the transponders or the antenna must be in a fixed position. Possible
applications are:
Position detection of an Automated Guided Vehicle (AGV), i.e. the antenna
moves with the vehicle and the transponders have a fixed position.
Position detection of moving parts (e.g. on mobile robots or electric monorail
conveyors), i.e. the transponders move, the antenna is located at a fixed posi-
tion.
The field of application of the transponder antenna HG G-71915ZA is the position
detection of Automated Guided Vehicles (AGV).
The transponder antenna HG G-71915ZA may only be used by qualified personnel

Device Description HG G-71915ZA | English, Revision 01 | Date: 09.09.2021
12 Chapter 2 – Safety Instructions
Ensure that interference in the ground or on the vehicle does not trigger a signal
higher than 100 units in the antenna and that all transponders are read at a suf-
ficiently high distance from this signal. Otherwise, false readings or unrecog-
nized transponders may occur.
Mount the transponder antenna so firmly on the vehicle that its position cannot
change during normal operation. Otherwise, the position data will be incorrectly
evaluated by the higher-level system and the vehicle may drive off track.
Although dirt does not affect the position detection itself, the transponder
antenna should be protected from dirt and moisture (e.g. splash water from the
wheels of the vehicle) and cleaned regularly, otherwise wear and tear on the
antenna will increase.
2.5 Obligations of the Operator
When using the transponder antenna, the operator must ensure that
all persons within the area of influence of an automated system (e.g. automated
guided vehicle (AGV)) are informed about the type of application and the associ-
ated hazards,

18 Chapter 5 – Operating Principle
5Operating Principle
The transponder antenna detects the position of moving parts by means of passive
transponders. Downstream navigation systems (e.g. vehicle PLC, Götting navigation
controller HG G-73650ZA), which process the data detected by the antennas, can be
used to control automated guided vehicles (AGVs) contact-free.
All important settings, calibrations and updates can be made via the USB interface.
Figure 6 Simplified principle of transponder positioning
In position detection with transponders, a transponder antenna detects a transpon-
der at the nominal reading distance and determines its position in the antenna field.
Typically, the transponders are mounted at fixed positions on the ground and the an-
tenna moves above them, e.g., by being attached to a vehicle moving over a course.
Alternatively, the antenna may be mounted at a fixed position and the plant part with
transponder moves relative to it, e.g., an arm of a robot or an electric monorail.
In the following, we refer to the application on automated guided vehicles (AGVs)
with transponders in or on the ground and the antenna installed on the vehicle.
5.1 Position Detection with Transponders
In position detection with transponders, the antenna permanently irradiates the area
under its reading side with its transmission frequency. The transponders are passive
and do not require an energy supply of their own. As soon as the antenna passes
over a transponder, it is inductively supplied with energy via the antenna's energy
field. It automatically wakes up and uses the received energy to send back its code
at half the transmission frequency of the antenna. Thus, only pairings of antennas
and transponders whose transmit and receive frequencies match are possible. Fur-
thermore, there are other systems for transmitting and decoding the code which are
not described in this device description.
Only one transponder at a time may be in the antenna's reading range. In addition to
the transponder code, the antenna emits a positioning pulse (PosiPulse) when it
moves over a transponder and the center axis of the antenna crosses the transpon-
der. This enables the detection of predefined positions.
Due to the low operating frequencies (128/64kHz), transponder detection is practi-
cally not affected by non-conductive materials (liquids, gases or even solids).

Operating Principle – Chapter 5
The transponder code can be reprogrammed via the antenna for compatible read/
write transponders. The programming process can alternatively be triggered via bus
telegrams (section 10.3 on page 39) or the service interface (section 9.2.5 on page
36).
5.2 Reading Area and LEDs
The reading area comprises the entire area below the reading side of the antenna at
the reading distance.
Figure 7 Reading area
The antenna is designed to be 1-dimensional. It detects a transponder in the reading
range and generates a PosiPulse when the center of the antenna moves over the
transponder. It can also detect under which half of the antenna a transponder is lo-
cated.
The antenna indicates its operating status via LEDs that illuminate the lane. Thus,
even when the antenna is mounted under a vehicle, one of the following states can
be detected from the outside.
