NOTICE
Shortening decoding results that are too long: If the bar code information (bar code possibly in-
cluding supplementary information such as the check sum) does not fit in the selected module
width, the decoding results are shortened. This shortening is either from the left or the right de-
pending on the setting in module 30 – Data formatting.
Shortening is indicated by the passed bar code data length.

Module 30 – Data formatting
PROFINET-IO module identifier
Module ID: 1030
Submodule ID: 1
Description
The module defines the output string for the case that the BCL 248i could not read a bar code. In addition,
the initialization of the data fields and the definition of unused data ranges may be set.

start
The parameter defines the state
of the data at the start of the read-
ing gate.

Bit
0: Input data re-
main on the old
value
1: Input data is
reset to the initial
value
0
Data alignment
The parameter defines the align-
ment of the data in the result field
and thus also controls possible
shortening of a decoding result
that is too large.
