1.3 Description of AMS 200…functions
The AMS 200… optical laser measurement system measures distances to stationary as well
as moving plant components. The measurement principle is based on the measurement of
the propagation time of the radiated light. The light emitted by the laser diode is reflected
onto the receiving element of the laser measurement system by a reflector. The AMS 200…
calculates the distance to the reflector based on the propagation time of the radiated light.
The high absolute measurement accuracy of the laser measurement system as well as the
fast integration time are designed for position control applications.
1.4 Nomenclature
AMS 200 = Absolute Measurement System 200.

Notice!
Below you will find a short description for the initial commissioning of the laser measurement system. Detailed explanations for all listed points can be found throughout the
handbook.
Mechanical design
The AMS 200… and the corresponding reflector are mounted on two opposing, planeparallel, flat and vertical walls or plant components.
For error-free position measurement there must be unobstructed visual contact between the
AMS 200… and the reflector.
Mounting the device
The laser is mounted on a vertical wall using 4 screws (M5).
Alignment is performed using 2 adjustment screws. (Laser light spot centred on the
reflector.) Once aligned, the device is secured in place with the knurled nut and locked using
the M5 nut.
➔ chapter 7.1 on page 31
Mounting the reflector
The reflector is mounted on a vertical wall using 4 screws (M5). The reflector is angled using
the included shims. For specific information please refer to chapter 5 (Reflectors).
AMS 200… and reflector oppose each other such that the laser light spot is positioned in the
centre of the reflector.
➔ chapter 5 on page 19
Attention!
For position calculation purposes the laser beam must reach the reflector without interruption. Ensure that the laser beam is always incident on the reflector when the system is moving.
Connecting PWR, PROFIBUS, Interbus, SSI or RS 232
The laser measurement system is connected using M 12 connectors.
The voltage supply is connected via the PWR M 12 connection.
The PROFIBUS/Interbus is connected via BUS IN or, in the case of a continuing network,
via BUS OUT.
PROFIBUS:
I
NTERBUS
SSI:
RS 232:
If BUS OUT is not used, the PROFIBUS must be terminated at this point with a M 12 terminator plug (see chapter 10.5 "Accessory PROFIBUS terminating resistor"PROFIBUS).
:
The Interbus does not require a terminator plug at the BUS OUT connection.
The SSI interface is connected via the SSI M 12 connection.
The RS 232 interface is connected via the SERVICE M 12 connection.

5 Reflectors
5.1 General information
The laser measurement system measures distances against a reflective tape (reflector).
The reflective tape is available pre-mounted on an aluminium plate or as self-adhesive tape.
Different sizes of reflective tape are available for various measurement distances and installation sites.
Notice!
On the front side of the reflector is a stick-on label with the designation "TOP". Particularly
for measurement distances greater than 120 m, it is important to always mount the reflector
with the reflector side labelled with "TOP" so that it has the same alignment as the M 12
connections of the AMS 200:
• M 12 connections of the AMS 200 on top–> TOP on reflector on top !
• M 12 connections of the AMS 200 on side–> TOP on reflector on side !
• M 12 connections of the AMS 200 on bottom–> TOP on reflector on bottom !
Attention!
The range, accuracy and consistency specified in the technical data for the laser measurement system are achieved only when using the reflective tape specified by Leuze electronic.
5.2 Specifications of reflectors
The reflective tape consists of a white, microprism-based reflective material. The beam
reflection system is located under a hard, highly transparent, protective coating. The adhesive tape is covered with a protective foil.

Attention!
For applications in low-temperature areas less than -10 °C, the max. distance may be affected when measuring distances greater than 120 m. For distances greater than 120 m we recommend "floating" mounting of the reflective tape, i.e. the edge of the foil may only be
fastened or secured with an additional adhesive tape. For measurement distances greater
than 120 m avoid full-surface adhesive mounting.

5.3 Selecting reflector sizes
Depending on the system design, the reflector may either be mounted on the moving vehicle
or in a stationary location.
Attention!
The reflector sizes shown below are recommended by Leuze electronic for mounting the
AMS 200 on a vehicle. The system supplier must always perform a check to determine
whether a larger reflector than the one recommended has to be used by reason of mechanical travel tolerances. This applies, in particular, when the laser measurement system is
mounted on a vehicle. The laser beam must not leave the reflector during travel. For stationary mounting of the AMS 200, a small 200 x 200 mm reflector will be adequate for all measurement distances.

5.5 Mounting the reflector
5.5.1 General information
The reflective tape of the "Reflective tape …x…-S“ – self-adhesive – series must be affixed
to a flat, clean and grease-free mounting surface. We recommend using a separate metal
plate, which is to be provided on-site.
The reflective tape must be angled as described in Table 5.4.
The reflective tape of the "Reflective tape …x…-M" – mounted on aluminium plate –
series is provided with appropriate mounting holes. Spacer rings are provided in the packet
for achieving the necessary pitch angle. For further information see Table 5.4.

5.5.2 Mounting the reflector
The combination of laser measurement system and reflective tape is mounted in such a way
that the laser light spot hits the reflective tape as centred as possible and without interruption.
For this purpose use the provided adjustment elements on the AMS 200… (see chapter 7
"Mounting"). If necessary, remove the protective foil from the reflector.
Notice!
The reflector must be angled. To do this, use the spacer rings. Angle the reflectors so that
the surface reflections of the foil seal are deflected to the left, right or upwards. Avoid
a downward pitch, as additional reflections may occur on the running rails. The
chapter 5.5.3 gives the correct pitch with respect to the reflector size and thus the length of
the spacer rings.

Parameters set via the display are overwritten by the parameters set in the GSD modules
when operating the laser measurement system on the Profibus. For GSD modules which are
not actively used on the PROFIBUS, the default settings of the laser measurement system
apply, see "Detail description of the modules" on page 45. Thus the PROFIBUS presets
values to all parameters.
Attention!
If parameters are changed via the display during bus operation, the laser measurement system is separated from the PROFIBUS when parameter enabling is activated via the display.
Parameters set via the PROFIBUS are moved to the background, and changes to parameters can then be made via the display. When parameter enabling is exited, the laser measurement system is automatically reconnected to the PROFIBUS. Upon connection to the
PROFIBUS, the laser measurement system receives all parameters from the PROFIBUS
master.
Changes made via the display are overwritten!
Device settings for operating the laser measurement system on the PROFIBUS are
managed and configured exclusively by the PROFIBUS master.
If the PROFIBUS is deactivated and the laser measurement system transmits its data via
the SSI interface, it may be necessary to adjust the laser parameters via the integrated display. In this operating mode the PROFIBUS default parameters have no effect; the SSI default parameter set applies (see chapter 8.2.4).
Settings made on the display apply permanently. As the parameters are only stored in the

7.1 Mounting the AMS 200…
Figure 7.1: Mounting the device
The AMS 200… and the corresponding reflector should be mounted on two opposing,
plane-parallel, flat walls or plant components. For error-free position measurement there
must be unobstructed line of sight between the AMS 200… and the reflector.
Use the M5 screws to mount the laser measurement system. Secure the screws with a
toothed lock washer to protect against loosening caused by vibrations.
The laser light spot has to be aligned so that it always hits the centre of the opposing
reflector, both at close range as well as at the maximum measurement distance. Use the
two M5 hexagon socket screws to align the device ("A" in figure 7.1). When aligning
please ensure that the knurled nut and the M5 lock nut ("B" in figure 7.1) are opened wide.
Mounting
TNT 35/7-24V
Attention!
To prevent the laser measurement system from becoming misaligned during continuous operation, then hand-tighten the knurled nut and securely lock into place with the M5 nut
("B" in figure 7.1). Knurled nut and M5 nut must not be tightened until after aligning.
Attention!
The device must not be opened. Failure to comply will render the guarantee void. Warranted
features cannot be guaranteed after the device has been opened.

7.1.2 Mounting distances
Reflector 1 Reflector 2
Minimum parallel distance to adjacent AMS 200
The smallest possible parallel distance to an adjacent AMS 200 is determined by the
maximum measured distance as well as the characteristics of the reflector. To prevent adjacent devices from interfering with each other the parallel distance of the laser light spots on
the reflector is crucial.
Figure 7.3: Minimum parallel distance X to adjacent AMS 200
Min. parallel distance of the laser light spot X = 100 mm + (max. measurement distance in
mm • 0.01)
Notice!
Please note that travel tolerances could cause the two laser light spots to move towards
each other.
Mounting
X
If both AMS 200 devices are optically separated from each other, e.g. if mounted in different
shelf alleys, the parallel distance can be chosen somewhat smaller, as there is no interference in this case.
Minimum distance to an adjacent DDLS 200 optical data transmission device
The DDLS 200 series optical data transceivers and the AMS 200 do not interfere with each
other. Depending on the size of the used reflector, the optical data transceiver can be
mounted with a minimum mounting spacing of 100 mm to the AMS 200. The mounting
spacing is independent of the distance.
7.2 Mounting the reflector
The combination of laser measurement system and reflective tape or reflector is mounted in
such a way that the laser light spot hits the reflective tape as centred as possible and without
interruption.

8.1.4 General information on the GSD file
If the AMS 200… is operated in a PROFIBUS network, configuration must be performed
exclusively via the PROFIBUS. The functionality of the laser measurement system is
defined via modules. The parameters and their functions are structured in the GSD file using
modules. A user-specific configuration tool is used during PLC program creation to integrate
the required modules and configure them appropriately for the measurement application.
During operation of the laser measurement system on the PROFIBUS all parameters are set
to default values. If these parameters are not changed by the user, the device functions
using the default settings supplied by Leuze electronic. For the default settings of the device
please refer to the following module descriptions.
Notice!
A least one module in the GSD file must be activated in the configuration tool for the control,
usually the Position value module.
Notice!
Some controls make available a so-called "universal module". This module must not be activated for the AMS 200…
Attention!
The AMS 200… makes available a PROFIBUS, an SSI and an RS 232 interface. All interfaces can be operated in parallel. If the laser is operated via the PROFIBUS, the SSI/RS 232
parameters must also be changed via the PROFIBUS/SSI/RS 232 modules if they differ
from the default settings.
SSI/RS 232 parameters which are only changed via the display are overwritten by the
PROFIBUS manager with the SSI/RS 232 default values stored in the GSD file.
Notice!
For test purposes parameters can be changed via the display on a laser measurement system operated on the PROFIBUS. As soon as parameter enabling is activated on the display,
the device is deactivated on the PROFIBUS. All parameters set via PROFIBUS modules remain effective. Parameter changes can now be made via the display for test purposes. If parameter enabling is deactivated via the display, only the parameters set in the PROFIBUS
modules and the PROFIBUS default settings are in effect.
Parameter changes made via the display are no longer in effect on the PROFIBUS!
Attention!
The laser measurement system does not permanently store parameters changed via the
PROFIBUS. Following Power OFF/ON the currently configured parameters are downloaded
by the PROFIBUS manager. If no PROFIBUS manager is available following Power OFF/
ON, the parameters set on the display apply.

Behaviour of the AMS 200 on laser ON/OFF:
TNT 35/7-24V
If the laser light spot is positioned on the reflector when the laser diode is switched on, the
AMS 200 returns valid measurement values after approx. 330 ms.
If the laser light spot is not positioned on the reflector when the laser diode is switched on,
the AMS 200 cannot calculate any distance values. If the laser beam hits the reflector at a
later point in time while switched-on, the AMS 200 returns valid measurement values after
the following time span:
t = (measurement distance / 20 m) sec.
Example: Corridor change of a high-bay storage device during which the laser diode is not
switched off while travelling around curves.
Measurement distance 100 m –> t = 5 sec., measurement distance 200 m –> t =
10 sec.

8.1.6.9 Module 9: Error handling procedures
Description
The module makes parameters available to handle any errors should they occur.
In the event of a temporary error in the value/velocity calculation (e.g. plausibility error
caused by light beam interruption) the laser measurement system transmits the last valid
measurement value for a length of time xx which is to be configured.
If the configured time is exceeded, the error display or the faulty measurement value output
is activated.

8.1.6.10 Module 10: Velocity
Description
Outputs the current velocity with the configured resolution. The unit (metric or inch) is set in
module 1 (position value) and also applies to the velocity. If module 1 is not configured, the
AMS 200… operates with the default unit (metric).
The sign of the velocity is dependent on the count direction in module 1d.
In the default setting a positive velocity is output when the reflector moves away from the
AMS 200… When the reflector moves towards the AMS 200…, negative velocities are
output. If the "negative" count direction is configured in module 1, the velocity signs are
reversed.
Measurement value preparation averages all velocity values calculated during the selected
period to yield a velocity value.

8.1.6.11 Module 11: Static velocity limit value 1
Description
The static velocity limit value 1 function compares the current velocity with a velocity
stored in the configuration. This occurs in the configured range, which is defined by range
start and range end.
Notice!
If range start and range end are identical, velocity monitoring is not activated.
If a direction-dependent limit value check is activated via the direction selection parameter,
the values of range start and range end also define the direction. The check is always
performed from range start to range end. For example, if the range start is "5500" and the
range end is "5000", the direction-dependent check is only performed in the direction from
"5500" to "5000". The limit value is not active in the opposite direction.
If the check is independent of direction, the order of range start and range end is irrelevant.
Depending on the selected switching mode, if the value is above or below the defined
limits, the limit value status in module 16 is set and, if configured, the output is appropriately
set via module 4 or 5.

8.1.6.17 Module 17: SSI interface
Description
The module defines the parameters for the SSI interface.
Attention!
The SSI interface can only represent positive distance values. If negative output val-
ues are ascertained due to the offset or count direction, a zero value is output at the
SSI interface! In the event of a number overflow, all data bits are set to "1".
The unit, offset and count direction parameters of module 1 also apply to the SSI interface.
Notice!
If the SSI interface is not configured via module 17 (SSI interface) in PROFIBUS oper-
ation, the SSI interface is deactivated.
If the SSI interface is operated without PROFIBUS (PROFIBUS OFF/SSI ON), configuration
is performed via the display.

8.2 SSI
8.2.1 General information about the transmission procedure
Data communication of the SSI interface is based on differential transmission as used for
RS 422 interfaces. Transmission of the position value, beginning with the MSB (most significant bit), is thus synchronised with a clock cycle (CLOCK) specified by the control.
In the quiescent state both the clock line as well as the data line are at HIGH level. At the
first HIGH-LOW edge (point
it is ensured that the data cannot change during serial transmission.
When the next clock signal change from LOW to HIGH level (point
transmission of the position value begins with the most significant bit (MSB). With each
successive change of the clock signal from LOW to HIGH level the next least-significant bit
is transmitted on the data line. After the least significant bit (LSB) has been output, the clock
signal switches from LOW to HIGH for one last time and the data line switches to LOW level
(end of transmission).
A monoflop retriggered by the clock signal determines the time span before the SSI interface
can be called for the next transmission. This results in the minimum pause time between two
successive clock cycles. If time t
cent level (HIGH) (point
that the device is again ready for transmission.
Notice!
If the off-cycle of data transmission is interrupted for longer than t
will begin with a completely new transmission cycle with a newly calculated value.
➀ in figure 8.6) the data in the internal register are stored. Thus
= 20 µs has elapsed, the data line is returned to the quies-
m
➂ in figure 8.6). This signals completed data communication and
➁ in figure 8.6) occurs
= 20 µs, the next cycle
m
If a new transmission cycle is started before time t
has elapsed, the previous value is out-
m
put again.
Attention!
The SSI interface can only represent positive distance values. If negative output val-
ues are ascertained due to the offset or count direction, a zero value is output at the
SSI interface! In the event of a number overflow, all data bits are set to "1".

8.2.1.1 SSI sequence diagram
Clock sequence
Complete transmission cycle
Figure 8.6: SSI data transmission sequence diagram
Notice!
In the default setting the LSB bit is the error bit.
Attention!
Significance of the error bit:
By default a 25th error bit (LSB) is appended to the 24-bit measurement value.
The error bit is not included in the Gray coding of the measurement value.
The error bit is 1 = active, 0 = not active.
Device parameters and interfaces
Notice!
The data can be read out with a clock rate between 80 kHz and 800 kHz.
Attention!
Updating the measurement values on the SSI interface of the AMS 200:
The measurement value on the SSI interface of the AMS 200 is updated every 1.6 ms (default) independent of the clock frequency.
The update rate on the interface can be reduced to 0.2 ms via the display under the SSI
menu item or in PROFIBUS module 17.
The shorter update rate is only valid for the SSI interface and has no influence on the
PROFIBUS DP interface.

8.2.3 Notice regarding software parameters
Attention!
Using the PROFIBUS and SSI interface simultaneously:
The SSI interface settings are performed by the PROFIBUS. If settings which differ from the
default settings for the parameters, are to be used, they must be configured via module 17
(SSI interface).
Device parameters and interfaces
Using the SSI interface without PROFIBUS:
For this operating mode deactivate the PROFIBUS via the display (PROFIBUS = OFF).
Default parameters are stored in the laser measurement system for the sole use of the SSI
interface. The preset default parameters can be changed at any time via the display.
This also applies when using parameters which do not relate directly to the SSI interface
(for example: I/O 1 or I/O 2, position value or others).
The SSI interface remains active even during parameter enabling. Changes to parameters
have an immediate effect.

8.3.1 General information
The AMS 200/xxx-20-(H) is designed as an Interbus device. The functionality of the
AMS 200 is thereby permanently defined by default settings.
The baud rate of the data to be transferred is 500 kbit/s.
The RS 232 interface available on the AMS 200 can be used simultaneously with the
Interbus interface. The SSI interface cannot be used.
8.3.2 Activation/deactivation of the Interbus interface on the AMS 200
Notice!
The Interbus interface can be activated/deactivated via the display. With the Interbus activated, the IBS lettering is visible on the display. By default the Interbus interface is activated
and the RS 232 interface is deactivated.
If Interbus "OFF" is switched, the IBS lettering is also deactivated on the display.
Continuing participants are addressed even with the Interbus deactivated.
A deactivated AMS 200 can be recognised on the process data monitor of the Interbus
master by means of the data double word 80 00 00 00

For connecting BUS IN and BUS OUT we recommend our ready-made Interbus cables (see
chapter 10.8 "Accessory ready-made cables for interface connection" on page 103).
Attention!
The laser measurement system can be used to branch out the Interbus network. The con-
tinuing network is connected via BUS OUT.
The integrated SUPI (Serial Universal Peripheral Interface) automatically detects whether
additional participants are connected to BUS OUT. Termination of BUS OUT is not necessary.
8.3.4.2 Shielding and grounding concept
The cable shielding must be concentric and have the largest possible surface area on the
M 12 connector (thread).
The M 12 thread for BUS IN is connected to the functional earth (FE) inside the AMS 200 via
an RC element (1MΩ || 15nF).
The M 12 thread for BUS OUT is conductively connected to the housing and is thus directly
connected to the functional earth (FE).

8.4.1 General information
The AMS 200 offers the option of using the SERVICE M 12 connection to communicate with
other devices via an RS 232 interface. The RS 232 interface can be used as a full-fledged
interface in parallel with the PROFIBUS, the SSI interface or the Interbus interface.
On delivery, the RS 232 interface is deactivated.

8.4.2 Activation/deactivation of the RS 232 interface on the AMS 200
If the RS 232 is used simultaneously with the PROFIBUS interface, activation is performed
via the GSD file in module 19.
If the RS 232 is used simultaneously with the Interbus or with the SSI interface, activation is
performed via the display.
Notice!
Upon consultation with Leuze electronic, a MA… connector unit can be used to convert
to the RS 485 or RS 422 interfaces.

8.4.4 Configuration via the control panel/display
Attention!
Simultaneous use of PROFIBUS and RS232
The settings of the RS 23 2 interface are performed by the PROFIBUS. For this purpose,
module 19 must be activated. If parameters other than those specified in the default settings
are used, they must be configured via module 19 (RS 232 interface).
Using the RS 232 interface without PROFIBUS
For this operating mode, default parameters are stored for the RS 232 interface by the laser
measurement system. The preset default parameters can be changed at any time via the
control panel/display.
This also applies when using parameters that do not directly affect the RS 232 interface.
This RS 232 interface is also active during parameter enabling. Changes to parameters
have an immediate effect.
