1 Trainer for Field Bus Applications CEAB Engineering and Technical Teaching Equipment INTRODUCTION The communication between industrial devices is made through field buses. The standardized field buses are the way to manage the large distances between devices in an industry and the connection between devices belonging to different manufacturers. The field buses provide a robust and tested way to transfer data between the different devices of an industry. The Profibus DP, Modbus RTU, Profinet IP, IO-link, etc. are a few examples of all the protocols used today. Every protocols have its specific functions. The Trainer for Field Bus Applications, CEAB, has been designed by EDIBON to allow the students to familiarize with the field bus networks. The CEAB unit is provided with a set of practical exercises, through which the students will familiarize with the Profibus field bus protocol, how to configure a Profibus network, how to read and write variables through an OPC server and OPC client, how to perform a mapping of the device signals, protocol conversion from Modbus RTU to Profibus DP, etc. ISO 9001: Quality Management (for Design, Manufacturing, Commercialization and After-sales service) European Union Certificate (total safety) 1 Certificates ISO and ECO- Management and Audit Scheme (environmental management) Certificate and Worlddidac Member

2 GENERAL DESCRIPTION The Trainer for Field Bus Applications, CEAB, provides the components to conform a real Profibus DP Network where the PC is the master device and different components included with the unit are the slave devices. The CEAB unit also allows to study protocols conversion through a gateway device, with an example of conversion from Modbus RTU to Profibus DP. The CEAB unit is based on a modular design structure whose functionality is divided into different modules to allow the student a better understanding of the unit. The modules provided with the unit are: Industrial controller, Analog Inputs Module, Analog Outputs Module, Digital Voltmeter, Set Point Generator, Digital Inputs Module, Digital Outputs Module, and the Interface Card.
