7.4.4.7 Device characteristics and system boundaries
Table 107: Device characteristics
Index Access Data type Description
86h R STRUCT
5 × UINT-16
This parameter contains the following MLG-2
device characteristics:
Component 1 = number of beams
Component 2 = beam separation
Component 3 = repeatability
Component 4 = minimum presence time
Component 5 = response time
•
The beam number reflects the number of beams from the MLG-2. Depending on
the model, the MLG-2 can have between 6 and 510 beams, only 250 beams for
the DPV0.
•
Beam separation: In order to achieve different levels of measurement accuracy,
the MLG-2 is available with different beam separations. (see "Beam separations
and detection height", page 15).
•
The repeat accuracy of a measurement result (reproducibility) is the amount
of time by which an object detection can differ from a previous or subsequent
detection. The reproducibility time is 1 × the scan time.(see "Scan time", page 17).
The reproducibility is output as an integer in µs.
•
The minimum presence time is the amount of time an object or gap must be in
the detection area in order to be detected. The minimum presence time is no more
than 2 × the scan time (see "Scan time", page 17).
The minimum presence time is output as an integer in µs.
•
The response time is the time it takes for an output to react following the detec‐
tion of an object/gap. The maximum response time is 3 × the scan time plus the
transmission time to the outputs (see "Scan time", page 17).
The response time is output as an integer in µs.

88h R STRG (12) This parameter contains the version of the
firmware.
The version of firmware in its delivery state can be found on the type label.
7.4.5 Beam evaluation
7.4.5.1 Zone measuring
The beams of the MLG-2 can be divided into four zones. Each zone can be assigned
one beam function or application. Zones and beam functions are assigned using the
outputs. The functions NBB Zone n, LBB Zone n, FBB Zone n, CBB Zone n and NCBB
Zone n are available for each zone (n = 1, 2, 3 or 4).
