Outside dimension
The beam function facilitates outside dimension measurement, for example.
•
If there are several objects in the detection area, then the blocked beams of the
objects are totaled.
IDI – Inside Dimension
Table 49: IDI
Index Access Data type Description
FBh R UINT-16 This module transfers the inside dimension of
an object.

Inside dimension
The beam function facilitates inside dimension measurement of a hole, for example.
•
If there are several holes in the detection area, then the beams made within the
objects are totaled.
RLC – Run-length code
Table 50: RLC – Run-length code
Index Access Data type Description
20h…2Fh R UINT-16 These modules transfer the run-length code of
the MLG-2.
20h…2Fh
21h = RLC2
…
2Fh = RLC16
The “run-length code” can be output instead of the complete status of all beams. This
code only contains the status change of the beams.
NOTE
The run-length code can contain a maximum of 16 values, i.e., 15 status changes. It is
therefore only useful for measuring objects with a small number of parts, e.g., a pallet.
Objects such as pallet cages are not suitable as they involve too many status changes.
