•
The count direction of the beams depends on the configured beam numbering.
NCBB – Number of Consecutive Beams Blocked

Index Access Data type Description
F6h R UINT-16 This module transfers the total number of con‐
secutive beams blocked.

Total number of consecutive beams blocked
The beam function facilitates object detection, for example.
•
If there are several objects in the detection area, the number of beams of the
largest object is output.
•
If there are several objects of the same size in the detection area, the object with
the lowest-value beam is used for the measurement.
NCBM – Number of Consecutive Beams Made
Table 45: NCBM
Index Access Data type Description
F7h R UINT-16 This module transfers the total number of con‐
secutive beams made.

Total number of consecutive beams made
The beam function facilitates hole detection, for example.
•
If there are several gaps in the detection area, the number of beams of the largest
free field is output.
•
If there are several gaps of the same size in the detection area, the gap with the
lowest-value beam is used for the measurement.
