Distance Output
The read head detects the distance from the zero point in the Y direction a Data Matrix code
tape and transmits this value to the control panel.
The reader indicates the vertical distance of the zero point in relation to the Data Matrix code
tape.

Note
Direction Decision
The direction decision at a branch of a Data Matrix code tape remains in effect until the read
head has moved more than 50 cm away from the branch.
It is not possible to change the direction decision within a branch!
Note
Branches/Intersections with Data Matrix Position Code
Observe the following guidelines with regard to the area 1 m before and after branches or
intersections of a lane with a position code:
•
The position codes of the main lane must run continuously for 2 m. The position codes of
the branching/intersecting lane must run continuously for 1 m. The read head outputs the
X-value of the Data Matrix code tape that is specified via the direction decision. .
•
The difference between the absolute position of the main lane and the starting position of
the branching/intersecting lane must be greater than 1 m.
