Introduction
Based on a concrete example, this manual guides you through four commissioning
steps during which you will become familiar with the basic functions of the
SIMATIC VS 130. When you have completed these steps, you will have a
functional application. The references to the manual will also help you to get a
general overview of the information it contains.
Depending on your degree of experience, working through the sample will take
between one and two hours.
With the Vision Sensor SIMATIC VS 130, you can capture the labeling codes of
products quickly, reliably and inexpensively and then send the read code to a
controller or computer.
SIMATIC VS 130 reads data matrix codes and works with overhead lighting. The
object is lit from above with the supplied ring flash.
Requirements
The following components should be available having been installed and wired
according the accompanying installation instructions.
Components:
•
A conveyor system with which the test objects are fed through.
•
Trigger signal to trigger evaluation.
Vision Sensor SIMATIC VS 130 comprising:
•
a
sensor head
with CCD sensor chip (CCD = Charge Coupled Device) for
sensing the code.
-
a
processing unit
for code evaluation, output of results, PROFIBUS
interface and parameter assignment
-

Task
The objects with the data matrix code are fed past the sensor head with a suitable
conveyor. They must be located fully within the sensor field of view when being
read. In the training mode, the character content of the code is saved.
In the evaluation mode, the current code is read and, if required, compared with the
saved content of the trained code. Depending on the results of the read operation,
the digital output signals are set: READ (code was localized and decoded),
MATCH (code matches the learned code), N_OK (code was not legible).
The result of the read operation is output via the RS-232 interface or via
PROFIBUS. It is also, of course, possible to filter the read character string and to
append additional characters at the start or end.

Stage 1: Adjusting the Sensor
Before you start to work with the SIMATIC VS 130, you must first align the sensor
head correctly using the setup software on a PG / PC. The setup software shows
you an image as seen by the sensor head.
Step
Activity
Result:
Start the setup software on the PC / PG
•
1
Once the setup software has started,
the sensor field of view is displayed on
the PC/PG monitor. The displayed
image is updated several times per
second.
Turn on the PG /PC and wait until the computer
has booted.
•
Turn on the processing unit.
•
Connect the two devices over a serial cable.
•
Insert the CD with the setup software
ADJUST-
SW
. The program starts automatically.
•
If the program does not start automatically, you can
start it manually by selecting the CD drive and
double-clicking on ADJUST-SW.
•
Turn the processing unit to
Adjust
.
2
Adjust the sensor
•
Bring the data matrix code into the image.
•
Set a sharp image.
•
Correct the shutter speed and the brightness if necessary.
•
Minimize reflection.
•
Activate the
Triggered only
check box to test the trigger signal.
•
Activate the
Read
check box to check whether the code can be read, and make any
necessary fine adjustments.
Note:
If you have too many errors, clean the lens and diffuser with a lint-free cloth.
3
Secure the sensor and then check the correct sensor position.
