Technical Description BE-90 PBELECTRONIC GmbH2 Safety notices2.1 Safety standardsThe barcode positioning system BE-90 PB and the modular hoods with integrated connectorsBE-90 CU PB3/BE-90 CU PB5 have been developed and manufactured underobservation of the applicable European standards and directives.2.2 Intended useAttention!The protection of personnel and the device cannot be guaranteed if the device is operatedin a manner not corresponding to its intended use.Barcode positioning systems of the type BE-90 PB are optical measuring systems whichuse visible red laser light to determine the position of the BE-90 relative to a permanentlymounted barcode band.The modular hoods with integrated connectors BE-90 CU PB3/BE-90 CU PB5 are intendedfor the easy connection of barcode positioning systems of type BE-90 PB in aProfibus system and for the setting of the respective Profibus address(see chapter 6.3 "Address setting").In particular, unauthorised uses include:• rooms with explosive atmospheres• operation for medical purposesAreas of applicationThe barcode positioning system BE-90 PB has been developed in particular for the followingareas of application:• High-bay storage devices and lifting gear• Crane systems• Side-tracking skates• Transfer machines• Telpher linesTR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 08.07.2002 TR - E - BA - GB - 0025 - 00 Page 7 of 50

Technical Description BE-90 PBELECTRONIC GmbH3 DescriptionInformation on technical data and characteristics can be found in chapter 4.3.1 BE-90 PB device constructionFigure 3-1: BE-90 PB device construction3.2 ApplicationAnywhere systems are moved automatically, it is necessary to correctly determine theirpositions. This is achieved using various measurement techniques. In addition to mechanicalmeasurement sensors, optical methods are particularly well suited for determiningpositions as they operate without mechanical wear and slippage.Unlike other optical measurement methods, the barcode positioning system is not restrictedto linear movements. It can also be used flexibly in curved systems. Anywherethe longwearing barcode band can be attached, it is possible to use the BE-90 to determinethe position to within a millimetre.Guide tolerances of the system play no roll as the permitted separation between bandand BE-90 allows for large deviations in distance.TR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 08.07.2002 TR - E - BA - GB - 0025 - 00 Page 9 of 50

The purpose of both hoods is to connectthe BE-90 PB to the Profibus. For this, they feature one Profibus IN and one ProfibusOUT connection each, as well as an internal switch for address setting.If only the connection to the Profibus is intended, type BE-90 CU PB3 is sufficient.If, in addition, switching input and output are to be connected, an BE-90 CU PB5 is required.Although switching inputs and outputs are available on the voltage supply connector,the switching inputs of the BE-90 CU PB5 have the advantage that a standardsensor connector can be used.Figure 4-1: BE-90 PB with BE-90 CU PB5TR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 08.07.2002 TR - E - BA - GB - 0025 - 00 Page 13 of 50

Technical Description BE-90 PBELECTRONIC GmbH7 Profibus7.1 General informationThe BE-90 PB with BE-90 CU PB3/BE-90 CU PB5 was developed as a Profibus device.The functionality of the device is defined via parameter sets which are clustered inmodules. These modules are included in a GSD file, which is supplied as an integralpart of the device. By using a user-specific project tool, such as, e.g., Simatic Managerfor the programmable logic control by Siemens, the required modules are integrated intoa project during commissioning and its settings and parameters are adjusted accordingly.These modules are provided by the GSD file.All input and output modules described in this documentation are described from thecontroller’s perspective:• Input data arrives at the controller• Output data is sent out by the controller.7.1.1 GSD FileThe GSD file can be found on the disc supplied with this documentation.This file stores all the data required for the operation of the BE-90 PB. This data consistsof device parameters required for operation of the BE-90 PB, Profibus operationparameters, and the definition of the control and status bits. If parameters are changedin the project, for example, these changes are stored in the project, not in the GSD file.The GSD file is a certified part of the device and must not be changed manually. The fileis not changed by the system either.7.2 Structure of the project modulesIn the current version, a total of 17 modules are available for use. The modules may beincluded into the project according to requirements and application.The modules fall into the following categories:• Parameter module for the scanner configuration• Status or control modules that influence the input and output data.• Modules that may include both parameters and control or status information.iThe category of each module is marked with a cross in the overview.Notice!At least one module must be activated to permit operation of the device at the Profibus DP.TR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 08.07.2002 TR - E - BA - GB - 0025 - 00 Page 30 of 50
