Figure 67: Beam status — Example 2
This example shows an MLG-2 with 30 beams.
•
The green beams have been made.
•
The red beams have been blocked.
•
The bits represent the status of the beams on the MLG-2 (made = logical 0,
broken = logical 1).
•
Beam 1 is represented by bit 0; beam 30 by bit 29.
•
Superfluous bits receive the status logical 0 (in the example, bits 30 and 31).
•
The count direction of the beams depends on the configured beam numbering (in
the example, beam 1 on the connection side).
