PROFIBUS
50 BCL 34 Leuze electronic
8.3.1 Code table extension
Modules 1-4
The modules extend the code type tables of the device parameters and permit the addi-
tional definition of a further 4 code types together with the respective number of digits.
Parameters
Input Data
none
Output Data
none
8.3.2 Multilabel
Module 5
The module permits the definition of barcode types with a different number of digits and/or
code type in the reading gate and provides the necessary input data.
If several barcodes are read in a reading gate, these barcodes are transmitted in sequence
in order to save memory in the controller. This requires a handshake, which is achieved by
using the input and output data.
Parameter Description Rel.

Code type
Released code type;
no code means that all subsequent code tables
are also deactivated.
The valid number of digits also depends on the
code type.
