Operating serial
output models
Analogue out (FBB)
Dip switch setting:
In this set-up the light curtain drives together the Serial and the analogue output.
Note:The analogue output reflects the status of the FBB and is constantly updated. The serial output, on
the contrary, transmit its data only after interrogation code receipt.
The order of bitmaps is described in ’Bitmap of optics’ on page 5-5.
Holes detection function
Dip switch setting:
This function transmits the bitmap of beams with inverted bit signals.
The default setting
"0 = beam free and 1 = beam broken"
is converted into
"0 = beam occupied and 1= beam free".
Thus without object the bitmap of all optics will show "1", if the light curtain is aligned correctly.
Acquired data reflects the sum of beam acquisitions and is sent on interrogation code as
described in 5-3 ’Beam aquisition and data aquisition’ on page 5-4.
The order of bitmaps is described in ’Bitmap of optics’ on page 5-5.
