3.1 Device overview
3.1.1 General information
The BPS barcode positioning system uses visible red laser light to determine its position and its speed
value relative to a barcode tape that is affixed along the travel path. This takes place in the following steps:
• Read a code on the barcode tape (see following figure)
• Determine the position of the read code in the scanning beam
• Calculate the position to within less than a millimeter using the code information and the code position
relative to the device's center.
The position and speed values are then output to the controller via the host interface.
The BPS consists of device housing and interface connection hood for the connection to the control. The
BPS can optionally be delivered with display and optics heating.
The following connection hoods are available for the connection of the PROFINET interface:
• MS348 connection hood with M12 connectors
• MK348 connection hood with spring-cage terminals
• ME 348 103 connection hood with cables with M12 connector

3.1.2 Performance characteristics
The most important performance characteristics of the barcode positioning system:
• Positioning with submillimeter accuracy from 0 to 10,000m
• For the control at high traverse rates of up to 10m/s
• Simultaneous position and speed measurement
• Working range: 50 to 170mm; enables flexible mounting positions
• Interfaces: PROFINET fieldbus, PROFIBUS fieldbus, SSI, RS232/RS422, RS485
• Binary inputs and outputs for control and process monitoring
• Configuration via webConfig tool or fieldbus
• Diagnosis via webConfig tool or optional display
