11.11. Module Code 1D
11.11.1. Overview
Objective
All common 1D codes can be read with the 1D code module.
The following 1D codes can be read: Code39, Code128, 2/5 Industrial, 2/5 Interleaved,
Codabar, EAN-13, EAN-13 Add-On 2, EAN13 Add-On 5, EAN-8, EAN-8 Add-On 2, EAN-8
Add-On 5, UPC-A, UPC-A Add-On 2, UPC-A Add-On 5, UPC-E, UPC-E Add-On 2, UPC-E
Add-On 5, Code 93, MSI, PharmaCode, RSS-14, RSS-14 Truncated, RSS-14 Stacked,
RSS-14 Stacked Omnidir, RSS Limited, RSS Expanded, RSS Expanded Stacked.
Prerequisites
1. Sensor is correctly connected (see section 5.5)
2. Connection has been established from the sensor to the software (see section 10.1.1)
3. The camera is configured / images are selected (see section 11.2)
Procedure
Various code settings can be entered in order to assure reliable code recognition.
11.11.2. Settings
Property
The following settings/results appear.
Process Time [ms] Sensor processing time for the process steps
Module State
Error codes to give support in error diagnosis (see section 18.5)
Reading True Count The number of codes detected in the image.
Input Image Selection of the channel for the image input
Code Type The type of code can be selected:
Code39, Code128, 2/5 Industrial, 2/5 Interleaved, Codabar,
EAN-13, EAN-13 Add-On 2, EAN13 Add-On 5, EAN-8, EAN-
8 Add-On 2, EAN-8 Add-On 5, UPC-A, UPC-A Add-On 2,
UPC-A Add-On 5, UPC-E, UPC-E Add-On 2, UPC-E Add-On
5, Code 93, MSI, PharmaCode, RSS-14, RSS-14 Truncated,
RSS-14 Stacked, RSS-14 Stacked Omnidir, RSS Limited,
RSS Expanded, RSS Expanded Stacked
Read Timeout The time during which the sensor attempts to read the code.
If reading is not successful within this period of time, the
process is aborted and the reading results are rendered in-
valid. Time can be set within a range of 0 to 20 seconds in
steps of 1 ms. Aborting the read attempt takes about 20 ms.
The module’s minimum processing time is thus also 20 ms.
Reading Max Count The maximum number of codes to be read from the image
is specified.
Quality
Grading
Quality grading of the code in accordance with ISO/
IEC 15416 can be activated. Note: Activation of this func-
tions increases the module’s decoding time.
Note: The results of the code evaluation in accordance with
the standard can be found in the configuration reading list
(see section “11.11.3.1. Reading List” on page 126).
