Table 19: Example run-length code with the first beam blocked
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.
3.9.2 Preliminary evaluation
Beam functions for preliminary evaluation
The MLG-2 creates a preliminary evaluation on the basis of the beam status, e.g.:
•
NBB – Number of Beams Blocked
•
NBM – Number of Beams Made
•
LBB – Last Beam Blocked
•
FBB – First Beam Blocked
see table 33, page 107: Table shows all available functions.
The results of the preliminary evaluation can be output via the data interfaces and
processed further externally. Alternatively, they can first be processed in a function pro‐
gramming option in the MLG-2.
Function programming for the MLG-2 Pro
Function programming can be used to carry out complex applications with variables,
operands, and functions in SOPAS ET.
1st option:
The beam functions are directly linked with the outputs.
Example:
Q1 = Total number of beams made (NBM) ≥ 30
The output Q1 switches when the total number of beams made is greater than or
equal to 30.
2nd option:
The MLG-2's beam functions are used to define beam function variables first.
Example:
BFVar 1: Total number of beams made (NBM) ≥ 30
BFVar 2: Number of consecutive beams blocked (NCBB) = 5
These can be linked to logical variables.
Example:
LogVar1 = BFVar 1 OR BFVar 2
The logical variables can be linked in turn to the outputs (Q).
Example:
Q1 = LogVar1 = true
The output Q1 switches when the total number of beams made is greater than or
equal to 30 or when the number of consecutive beams blocked equals 5.
3.9.3 Configurable applications of the MLG-2 Pro
The MLG-2 provides predefined applications which are assigned to the outputs. The fol‐
lowing options are available for configuring the applications:
