2.1 Use and Application

Intended Use
This device, when used together with a Data Matrix code tape affixed to the floor, constitutes a high-resolution lane tracking and positioning system. It can be used in all applications where auto-guided transport systems 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 includes a camera module and an internal illumination unit, which the read head uses to detect a strip of Data Matrix code tape stuck to the floor for lane tracking and nav­igation. The read head also detects Data Matrix tags to navigate within a grid.
The read head is located on an auto-guided transport system and guides this system along the Data Matrix code tape.

Product Description
Tag Mode
In addition to lane tracking, the read head can also be used 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 auto-guided transport system in relation to the zero point of the Data Matrix tag to the control panel.
Tag mode allows the auto-guided transport system to move freely in as large a grid as desired, without having to mark the traverse distances with code tapes.
Figure 2.2 Auto-guided transport system with Data Matrix tags
The read head switches automatically between tag mode and lane tracking. This allows a transport system to be guided from one Data Matrix tag grid to another via a Data Matrix code tape.
Thanks to its comprehensive and simple parameterization options, the read head can be opti­mally adapted to suit any application.

Product Description

2.2 RS-485 Interface

The read head is equipped with an RS-485 interface for communication purposes, i.e. parame­terizing the read head functions or reading out current process data during operation. This interface is operated in 8-E-1 operating mode and is fitted with a terminator that can be acti­vated or deactivated by parameterizing the sensor head. The RS-485 interface supports the fol­lowing transfer rates:
9600 bit/s
19200 bit/s
38400 bit/s
57600 bit/s
76800 bit/s
115200 bit/s (default value)

3.1 Mounting the Read Head

Mount the read head on the auto-guided transport system using the four screws on the mount­ing adapter on the read head. Mount the read head so that the lens with ring light and camera module are aligned toward the floor.
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
Model number Read distance [mm] Depth of focus [mm]

Field of vision (w x h) [mm]
Read Head Dimensions

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.

3.2 Affixing the Code Tape

Caution!
Alignment
The Data Matrix code is not on the center line of the code tape.
Caution!
Stop edges
If you attach another code tape at the end of a previous code tape, the code pattern of 20 mm must be retained.
The code tape is made of silicone-free polyester film. A position marker appears every 100 mm along the lower edge of the code tape (see "Code Tape Dimensions"). These position markers are used to affix the code tape in the correct position. The back of the code tape is covered with a modified acrylate-based adhesive designed for permanent adhesion. Affix the self-adhesive code tape along the desired traverse distance. To do so, proceed as follows:
Position the code tape so that the www.pepperl-fuchs.com label and the position markings are to the right of the Data Matrix code in the X direction. The position values then increase along the X direction.

Affixing the Code Tape
1.
Clean the surface of any greasy or oily deposits and dust.
2.
Ensure that the surface is dry, clean, and stable.
3.
Pull away a few centimeters of the protective film at the beginning of the code tape. Place the code tape at the precise point of the required starting position on the surface, and press to attach.
4.
Then affix the code tape along the desired traverse distance. Please note the following information:
5.
Remove the protective film gradually so that the code tape does not accidentally adhere to the surface in an incorrect position. When affixing the code tape, ensure that it does not become creased or trap air bubbles.
The adhesive on the code tape hardens after 72 hours.
Note
Thermal Expansion of the Code Tape
The affixed code tape corresponds to the heat expansion coefficient of the surface with regard to its thermal expansion. Keep this in mind when installing expansion joints, for example.
Note
Expansion Joints and Code Tapes
If the system covers longer distances, the plant structure usually contains expansion joints. In this case, we recommend creating breaks along the code tape. The resulting gap must not exceed 75 mm.
Note
Inclines and Declines
If you affix the code tape on inclines or declines, cut the code tape several times at the transition point to the horizontal as shown.

Installation
Cleaning the Code Tape
Significant contamination on code tapes can impair detection by the read head. Clean the code tapes with isopropanol if necessary. If the contamination is severe, you can use a non-corrosive plastic cleaner, e.g., Caramba®.
Note
To avoid polishing the surface, do not apply strong pressure when cleaning. If the code tape has a shiny surface, this impairs detection by the read head.
Angle Output
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.
The read head detects the absolute angle in relation to the tracked lane with a maximum reso­lution of 0.1°. The angle is specified as an absolute value relative to the tracked lane, as a Data Matrix code tape contains 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°
