Trainer for Field Bus Applications

Model HV-EXP4448

Technical Description:-

Field bus technology plays a key role in modern-day process automation. The field bus permits networking of  terminal devices such as controllers, sensors or actuators in the plant  system (field level) with the higher-level control room (control level). A network of this kind can be quite extensive; line lengths of as much  as 1000 metres and more are possible.   This benchtop  trainer is used to teach the initial basics teps in field bus technology based on the example of Profibus DP. Various terminal devices (slaves)  are activated and read by a PC with a Profibus DP interface (master).  The required hardware is largely pre-configured. Students are able to  concentrate on the software programming of the field bus system. The  following specific topics can be covered: System configurator with DMF (Device Master File), bus topology, communication protocols, tags, OPC (OLE for Process Control) server, input and output of process data, and much more. The unit includes a digital process controller as well as analogue and digital input and output modules with a Profibus DP interface. Two potentiometers permit the simulation of input signals for the  controllers. A digital voltmeter displays the output signals. Digital  signals are generated by switches and displayed by LEDs.   The  controlled variable, manipulating variable and reference variable data  are delivered as standard signals at lab jacks, enabling the controllers to be incorporated into real processes at any time.  Clearly structured instructional material outlines the fundamentals and provides a step-by-step guide through the exercises.
