Bar code tape
5.1
General information
The bar code tape is available in different variants:
• BCB bar code tape with 40 mm grid, Code128 with character set C, increasing in
increments of 4 (e.g., 000004, 000008, ... )
• BCB8 bar code tape with 30 mm grid, Code128 with character set C, increasing in
increments of 3 (e.g., 000003, 000006, ... )
CAUTION
Bar code tape!
BPS 8 is set for bar code tape BCB8 with a 30 mm grid by default.
The BPS 8 can be configured for position measurement with a 40 mm bar code tape with
the BPS Configuration Tool.
A bar code tape consists of a sequence of individual position bar codes in one of the two
grids. Defined cut marks are provided for cutting the BCB.
The bar code tape is delivered on a roll. A roll contains up to 200 m of BCB. The BCB always
starts with the lowest position value at the outside of the roll (this is the value '000000' for
standard tapes). The BCB ends at the inside on the wrapping core with the largest position
value. If more than 200 m of BCB is ordered, the total length is divided into rolls of 200 m.
Bar code tapes with special requirements with respect to height, length and value range can
be ordered from Leuze electronic (see chapter 12.2 "Type overview: Bar code tape").
NOTE
Value range for BCB with special requirements!
When ordering bar code tapes with special requirements, make certain that the value
range contains only values that are divisible by three (BCB8 with 30 mm grid).
It may otherwise not be possible to purchase and use repair tapes.
NOTE
Only one BCB type per system!
In a given system, use either only BCB8 with 30 mm grid or only BCB with 40 mm grid.
If different BCB grids are used in one system, the BPS cannot ensure an exact position
determination.
