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

an LED overhead lighting unit , red, degree of protection IP65 as ring

flash (order number 6GF9 004-8BA)

cables to connect the individual components

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

•

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 .

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.

Secure the sensor and then check the correct sensor position.
