Function

The BPS uses visible red laser light to determine its position relative to the barcode band.
This essentially takes place in three steps:
1. Reading a code on the barcode band
2. Determining the position of the read code in the scanning area of the laser beam
3. Calculating of the position to within a millimetre using the code information and the
code position
The position value is then transferred to the controller via the Profibus DP.

Advantages

• Easy installation and commissioning
• Teach function for the "zero point", i.e. it is not necessary to exactly affix the barcode
band.
• Data output via the integrated Profibus DP.
• The function of the BPS makes it possible to attach the barcode band only at those
locations where it is necessary that the position be known exactly.
• Positioning of non-linear movements as well
• No referencing necessary following voltage drop
• Thanks to the large scanning depth, it is possible to compensate for mechanical toler-
ances.
• It is possible to exactly determine positions from distances of 10000 metres.

Modular hoods with integrated connectors MS 34 103/MS 34 105

The modular hoods with integrated connectors are necessary accessories for connecting a
BPS 34 in a Profibus system. They are used to feed through the Profibus connections, set
the Profibus address, and supply voltage to the BPS 34.
MS 34 103
The MS 34 103 offers the following interfaces:
• Profibus In (DP IN)
• Profibus Out (DP OUT)
• voltage supply (PWR IN)
MS 34 105
In addition, the MS 34 105 offers the following interfaces:
• for the modular service display (MSD)
• switching inputs and outputs (SW IN/OUT)
Please refer to chapter 5 for further information regarding the modular hoods with integrated
connectors.
