Logic levels are used in standard numbering systems when the significance level flag is set to 1.
If the numbering system is A1-07-03 where:
|2||1||Line 1 in factory A|
|3-5||-07||7th Group of equipment on Line 1|
|6-8||-03||3rd Piece of equipment in 7th Group|
Then the level logic is 01222333.
0 = Character in position 1 is the first level (A in the example)
1 = Character in position 2 is level 2 (1 in the example)
222 = Characters in positions 3-5 is level 3 (-07 in the example)
333 = Characters in positions 6-8 is level 4 (-03 in the example)
