Product Description
2 Product Description
2.1 Use and Application
Intended Use
This device, when used together with a colored tape affixed to the floor and code tapes printed
with Data Matrix codes, constitute a high-resolution lane tracking and positioning system. It can
be used in all applications where automated guided vehicles (AGV) are to be positioned
precisely at marked positions along a given lane.
The read head forms part of the positioning system in the Pepperl+Fuchs incident light
process. The read head's features include a camera module and an integrated illumination unit.
The read head uses these features to detect a colored tape stuck to the floor or a painted color
lane to track the lane. The read head detects Data Matrix tags to navigate within a grid. The
read head also detects control codes and position markers in the form of Data Matrix codes
printed on a self-adhesive code tape. Data Matrix code tapes and Data Matrix tags have priority
over colored tapes or colored lanes.
The Data Matrix code tapes are installed in a fixed position instead of or along with the colored
tape. The read head is located on an automated guided vehicle (AGV) and guides this vehicle
along the colored tape.
Figure 2.1 Automated guided vehicle with green colored tape
Note!
Priority
Data Matrix code tapes and Data Matrix tags have priority over colored tapes or colored lanes.
If the read head detects a Data Matrix code tape or Data Matrix tags in the field of view, colored
tapes or colored lanes in the field of view are ignored.

ag Mode
In addition to the tracking, you can use the read head in tag mode. The read head detects Data
Matrix tags, which are typically glued onto the floor in a grid. The individual Data Matrix tags are
numbered consecutively and include position information. The read head reports the position
of the AGV in relation to the zero point of the Data Matrix tag to the controller.
The tag mode allows the AGV to move freely in as large a grid as desired, without having to
mark the crossing paths with lane tapes.
Figure 2.2 Automated guided vehicle with Data Matrix tags
The read head switches automatically between tag mode and lane tracking. This allows an
automated guided vehicle to be guided from one Data Matrix tag grid via a colored or Data
Matrix lane to another Data Matrix tag grid.
The extensive yet user-friendly parameterization options as well as the configurable inputs and
outputs mean that the read head can easily be adapted to suit each application.

3 Installation
3.1 Mounting the Read Head
Mount the PGV... read head on the automated guided vehicle using the four screws on the
mounting adapter on the read head. Mount the read head in such a way that the lens with the
ring light and camera module are directed toward the colored tape.
The mounting must be stable enough so that the read head does not leave its depth of focus
range during operation.
The distance between the read head and the floor should be the same as the read distance of
the read head.
Optimum Read Distance
Hysteresis
If the read head has detected a colored tape, this colored tape can move in the Y direction from
the zero point within the viewing window. The maximum Y value at which the read head can still
capture this distance is designated as Y Value Out in the following table.
If the read head swivels onto a colored tape, the read head can capture the distance of the
colored tape from the zero point only if the tape is less than a certain distance away from the
zero point. This distance is designated as Y value In in the following table. The difference
between Y Value Out and Y Value In is the hysteresis. See "Distance Output" on page 16.
Order designation Read distance [mm] Depth of focus [mm] Field of vision (w x h) [mm]

3.2 Mounting the Colored Tape and Code Tape
Colored tape
The colored tape must be flexible, conformable, and resistant to abrasion, with a matte finish.
The colored tape must meet the following specifications:
■ Tape width: 10 mm ... 40 mm
■ Color of the tape
• Blue = RAL 5015
• Green = RAL 6032
• Red = RAL 3001
■ Tape thickness > 0.1 mm
The thickness of the tape is irrelevant to read head operation.
■ Breaking load > 25 N/cm
■ Breaking elongation > 180%
■ Adhesive strength > 2 N/cm
■ Temperature resistance: -20 °C ... 70 °C
Secure the colored tape to the floor such that the following conditions are met:
■ Data Matrix code tapes for positioning are used instead of the colored tape.
■ Data Matrix control codes are positioned parallel to the colored tape.
Color Selection
Select the color of the colored tape so that the contrast between the floor color and the color of
the colored tape is as great as possible. Ideally, use the complementary color.
Due to the integrated lighting of the read head, some floor colors appear to be different in the
camera. If you have problems with the color selection of the colored tapes, please consult your
contact at Pepperl+Fuchs.
Mounting the Colored Tape
1. Clean the surface of any greasy or oily deposits and dust.
2. nsure that the surface is dry, clean, and stable.
3. Please observe the following section "Basics" when mounting the colored tape and, if
necessary, the instructions from the colored tape manufacturer.
Caution!
When selecting the length of the mounting screws, ensure that the maximum insertion depth of
the screws in the threaded inserts on the read head is 8 mm.
Using longer screws may damage the read head.
Caution!
The maximum torque of the mounting screws must not exceed 9 Nm.
Tightening the screws to a higher torque may damage the read head.
Note!
Priority
Data Matrix code tapes and Data Matrix tags have priority over colored tapes or colored lanes.
If the read head detects a Data Matrix code tape or Data Matrix tags in the field of view, colored
tapes or colored lanes in the field of view are ignored.

Cleaning Colored ape/Code ape
Significant contamination on the colored or code tapes can impair the detection by the read
head. Clean the colored and code tapes with isopropanol if necessary. If the contamination is
severe, you can use a non-corrosive plastic cleaner, e.g., Caramba®.
Basics
The read head detects a colored tape on a floor as a lane. The width of the colored tape must
be between 10 mm and 40 mm; the default width is 18 mm. The zero point is located in the
center of the colored tape. You can use 3 defined colors. See the section entitled "Colored
tape"
The sensor always moves in the X direction. In the sensor's field of view, X indicates an upward
movement.
Figure 3.3 Field of view and coordinates of the sensor
Note!
To avoid polishing the surface, do not apply strong pressure when cleaning. A shiny surface of
the colored or code tapes leads to impairment in detection by the read head.

Figure 3.4 Curve radius: R ≥ 50 cm
Select a curve radius that can handle the turning circle of your automated guided vehicle. The colored tape must always
be located in the reading window of the read head.
Angle Output
The read head detects a change of the angle of the colored tape and the Data Matrix code tape
and outputs this value to the controller. The output value is different for colored tapes and Data
Matrix code tapes.
Colored tape
The read head detects the angle in relation to the tracked lane with a resolution of 360
(corresponds to 1°). The angle is specified relative to the tracked lane because a colored tape
does not include any direction information. The output angle covers the range from -45° to 45°.
The resolution is 1°.
Figure 3.5 Relative angle
R
Note!
Angles are specified as absolute values. The respective value is calculated from the resolution
selected under "Angle Resolution". With a resolution of 0.1°, an angle of 60° is output as
60°/0.1° = 600.

Data Matrix code tape
The read head detects the absolute angle in relation to the tracked lane with a maximum
resolution of 0.1°. The angle is specified absolutely relative to the tracked lane, since a Data
Matrix code contains tape direction information. The output angle covers the range from 0° to
360°. The resolution can be set to the following values:
■ 0.1°
■ 0.2°
■ 0.5°
■ 1°

Distance Output
The read head detects the distance from the zero point in the Y direction of a colored tape or a
Data Matrix code tape and outputs this value to the controller. The output value is different for
colored tapes and Data Matrix code tapes due to the lack of an X position for colored tapes.
Colored tape
The read head outputs the Y value at which the colored tape intersects the Y axis as the
distance.

Branches
The read head detects one lane at the lower edge of the field of vision and two lanes at the
upper edge of the field of vision; the read head indicates this as a branch.
The read head detects two lanes at the lower edge of the field of vision and one lane at the
upper edge of the field of vision; the read head indicates this as an intersection.
Branches or intersections can be displayed as follows:
Figure 3.9 Separate lane branches off/converges
The read head can make the following direction decisions based on the lane and possible
branches:
■ Follow left-hand lane
■ Straight ahead
■ Follow right-hand lane
The direction decision is signaled to the read head via the controller. If there is no direction
decision, the read head displays an error message.
Code apes for Control and Positioning
In addition to tracking the lane, the read head can also detect Data Matrix codes. This process
involves evaluating both control and position information. Data Matrix control codes are used
as event markers. Control codes provide information on branches. Data Matrix code tapes for
positioning indicate the absolute position of the read head.
Note the following conditions:
Data Matrix code tapes for positioning are used instead of the colored tape.
Data Matrix control codes are used in tandem with the colored tape or Data Matrix position
code.

Direction Decision
The direction decision at a branch of a Data Matrix code tape remains in effect until the read
head has moved more than 50 cm from the branch.
It is not possible to change the direction decision within a branch!
Note!
Priority
Data Matrix code tapes and Data Matrix tags have priority over colored tapes or colored lanes.
If the read head detects a Data Matrix code tape or Data Matrix tags in the field of view, colored
tapes or colored lanes in the field of view are ignored.
Note!
Branches/Intersections with Data Matrix Position Code
Observe the following guidelines less than 1 m before and after branching or intersection of a
lane with a position code:
■ The position codes of the main lane must run continuously for 2 m. The position codes of
the branching/intersecting lane must run continuously for 1 m. The read head outputs the
X-value of the Data Matrix code tape that is specified the direction decision. .
■ Do not use repair tape.
■ Do not use colored tape.
■ The difference between the absolute position of the main lane and the starting position of
the branching/intersecting lane must be greater than 1 m.
