Module 12 – Multi-label
PROFINET-IO module identifier
Module ID: 1012
Submodule ID: 1
Description
The module permits the definition of multiple bar codes with a different number of digits and/or code types
in the reading gate and provides the necessary input data.

This module is used to set the maximum and minimum number of bar codes which are to be decoded
within a reading gate.
If parameter "minimum number of bar codes" = 0, it is not taken into account at the decoder control. If it is
not equal to 0, this means that the bar code reader expects a number of labels within the set range.
If the number of decoded bar codes is within the set limits, no additional "No Reads" are output.
NOTICE
When using this module, the ACK mode should be activated (see chapter 8.7.1 "Module 10 –
Activations", "Mode" parameter). Otherwise there is a risk of losing decoding results if the con-
trol is not fast enough.
