Demokit - PROFIBUS

1. Introduction

The Smar pedestal mounted configuration Demokit makes possible acquire practical knowledge in of industrial equipment programming and calibration using the same configuration equipment and software developed for industrial control applications.

With the Demokit it is possible to simulate situations similar to those found by instrumentation professionals in real plants with high tech resources available at the market with the Profibus PA technology.

With the Demokit software it is possible to create control loops, from the most simple to the most advanced, enabling to know, implement, operate and supervise processes through software.

2. General Features

Pedestal-mounted Smar configuration Demokits are supplied with the devices already installed and mounted on the pedestal, which provide installation condition near the one to be found on the field. Additionally, it avoids the need for interconnections and mountings and is always ready for use.

At the instructor´s choice, the students can execute tasks wherever necessary to alter connections or dismount and mount equipment on the pedestal, whose accesses are fully facilitated.

Smar configuration pedestal mounting Demokits are designed to provide easy transportation, having features that meet the following premises:

• Compact mounting that makes unnecessary to install any equipment, as they are arrayed on pedestal. On its part, this is housed in a case that protects the equipment.
• Wheeled  case makes transportation and displacement easier;
• Easy to handle, can be maneuvered and lifted by a single person.

3. Construction Features

1. The controller and devices on each didactical kit are mounted on a pedestal-type rigid tubular structure of 1.5 inches so that all Demokit components are attached to it.

2. All accessories are supplied together with power cables, connectors and other components necessary to the didactical kit work.

3. All measurement and control equipment are compatible with the use in industrial environments and therefore are not only for essentially didactical purposes;

4. Embedded power supply, duly dimensioned to supply continuous voltage to all the equipment that make up the set and require this type of powering.

5. For each technological option, the measurement and control equipment use tools and interfaces proper to each technology for communication, configuration and supervision of the kit devices.

6. The kits are supplied with software tools with their respective permissions for the on-line configuration and monitoring of the Demokit devices and equipment. The software is compatible with the IBM-PC platform, with Windows XP and Windows 7 Professional 64 bits operating systems.
