The read head forms part of the positioning system in the Pepperl+Fuchs incident light pro- cess. 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 nav- igation.
PGV100R-F213-R4-1.5M 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.

PGV100R-F213-R4-1.5M Installation Note Mounting the code tape in curved areas 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. When you apply the code tape to the floor in curved areas, cut the code tape several times at the transition to the curve as shown.

PGV100R-F213-R4-1.5M Installation 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 reso- lution of 0.1°.

PGV100R-F213-R4-1.5M Commissioning Commissioning Direction Decision The read head requires a specification of the lane to be selected for the output of position infor- mation. In general, lane selection is possible via the IOs of the read head and via the request telegram.
PGV100R-F213-R4-1.5M Commissioning Parameterization Using Code Cards During parameterization, the read head scans special code cards optically and configures the relevant parameters. Simply hold the corresponding code cards at the correct distance in front of the lens on the read head. The standard code cards are in the appendix. Note Parameterization mode can be activated in the first five minutes after voltage connection.
PGV100R-F213-R4-1.5M Commissioning 4.2.1 The code cards "CANCEL", "USE", and "DEFAULT" Holding one of these cards in front of the reading head exits parameterization mode with the following consequences: • CANCEL: All parameter changes that are made but have not yet been saved are discarded. The reading head operates with the last valid parameters that were saved.
PGV100R-F213-R4-1.5M Operation and communication Operation and communication Communication via the RS-485 Interface The controller and read head communicate via the RS-485 interface during operation. Make sure that the basic communication settings have been made on the read head, such as setting the read head address and baud rate.
