2 Safety Guidelines This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring to property damage only have no safety alert symbol. The notices shown below are graded according to the degree of danger.!!! Danger indicates that death or severe personal injury will result if proper precautions are not taken. Warning indicates that death or severe personal injury may result if proper precautions are not taken. Caution with a safety alert symbol indicates that minor personal injury can result if proper precautions are not taken. Caution without a safety alert symbol indicates that property damage can result if proper precautions are not taken. Qualified Personnel Prescribed Usage Notice indicates that an unintended result or situation can occur if the corresponding notice is not taken into account. If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage. The device/system may only be set up and used in conjunction with this documentation. Commissioning and operation of a device/system may only be performed by qualified personnel. Within the context of the safety notices in this documentation qualified persons are defined as persons who are authorized to commission, ground and label devices, systems and circuits in accordance with established safety practices and standards. Note the following:! Warning This device and its components may only be used for the applications described in the catalog or the technical description, and only in connection with devices or components from other manufacturers which have been approved or recommended by Siemens. Correct, reliable operation of the product requires proper transport, storage, positioning and assembly as well as careful operation and maintenance.

3 Introduction These instructions guide you through a concrete example illustrating how to read a code and during which you will become familiar with the basic functions of the Vision Sensor SIMATIC VS130-2/VS130-2vcr. The references to the manual and the online help 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 VS130-2/VS130-2vcr you can capture the labeling codes of products quickly, reliably, and inexpensively and then send the read code to a controller or computer. The Vision Sensor SIMATIC VS130-2 reads data matrix, QR- and PDF417 codes and operates with overhead lighting. The object is lit from above with the supplied ring flash. The Vision Sensor SIMATIC VS130-2vcr reads Vericodes and also operates with overhead lighting. Prerequisites You have completed the installation and wiring based on the accompanying hardware installation instructions. You have also established 2 connections: Connection between PC and processing unit over Ethernet A connection from your Web browser (for example Internet Explorer) to the setup support using the Hyper Text Transfer Protocol (HTTP). (For more detailed information, refer to the online help) The following components are available. Components: Trigger signal to trigger evaluation. Vision Sensor SIMATIC VS130-2 or VS130-2vcr 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 interfacing, and parameter assignment - where applicable, an LED overhead lighting unit, red, degree of protection IP65 as ring flash (order number 6GF BA) - Cables to connect the individual components - hardware installation instructions for installation and wiring of the Vision Sensor SIMATIC VS130-2/VS130-2vcr A5E

4 CD with: - Vision Sensor SIMATIC VS130-2/VS130-2vcr manual (German and English) - Online helps (interfacing the Com Server of W&T, establishing the connection, setup support) - Getting Started - Installation Instructions - Compact Com Server manual from W&T - The installation manual SIMATIC S7-300 Automation System, Hardware and Installation - PROFINET IO documentation: Getting Started Collection for PROFINET IO, system manual PROFINET System Description, programming manual PROFINET IO From PROFIBUS DP to PROFINET IO, product information PROFINET IO Structure of the Diagnostic Data Records - the device master data file SIEM8111.GSD and the respective bitmap file VS1X0 N.DIB (for PROFIBUS DP) - the GSD file GSDML-V1.0-Siemens-VS xml (General Station Description) and the bitmap file vs100.bmp (for PROFINET I/O) an external power supply 24 V DC (2 A) a PG/PC 4 A5E

5 Task During reading, the code is fully within the sensor field of view and is not moving. Processing Unit PC/PG for setup support and code output Power Supply Ethernet (direct or over network) Sensor head Ring flash Light barrier Object with code Conveying unit A5E

6 Adjusting the Sensor Before you commission the Vision Sensor SIMATIC VS130-2/VS130-2vcr, you must adjust the sensor head correctly using the setup support on a PG / PC. The setup support shows you an image as seen by the sensor head. Step Activity Result 1 1. Turn on the PG /PC and wait until the computer has booted. 2. Turn on the processing unit. 3. Start your Web browser. 4. Enter the IP address of the processing unit. 5. In the dialog that opens, click on Adjust Sensor. Note: It may take several seconds for the page to display. 6. Click on the Adjustment button if a dialog other than the Adjust Sensor dialog is open. 2 Adjusting the Sensor 1. Bring the code into the image. Once the setup support has started, the sensor field of view is displayed on your PC/PG monitor. The displayed image is updated several times per second. 2. Focus the code by changing the distance between the sensor and the code. 3. Check that Auto V1 or Auto is set in the Exposure drop-down list box.. 4. Optimize the image quality of the code in the image. As soon as after Recognition the message "Successfully finished" appears, the code has been successfully decoded. You will see the result of the read in the "Result" box. If the decoding is successful, you will see the weaknesses in the current adjustment at the bottom right. By eliminating these weaknesses, you can improve the read reliability of the VS130-2/VS130-2vcr. 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. 6 A5E
