Installation of an eWON router on campus for industrial processes training

The CIFP (City of Béjar, Salamanca, Professional Training Centre) equipped its classroom with eWON router in the frame of the Control and Regulation of Automated Systems courses. The student can now practice their measurement, control and programming skills automation for an industrial process.

Before installing the eWON structure, communication with the PLCs was achieved via a point to point connection using the MPI port on each PLC, but this activity required a dedicated PC located beside the training rig.


The eWON 4005CD opens up the possibilities.

Integration of the eWON 4005 router with the training device has been a major advance in the classroom situation as it has improved the way in which the students’ training is carried out. Now, they no longer need a dedicated PC next to the training equipment, as the PLC can be accessed from each student’s own classroom workstation.

After the eWON had been integrated into the project, access became totally transparent for the students and it eliminated typical connection problems. As there is a direct connection with the PLC, this greatly aids debugging of programs and the detection of programming errors and it means that diagnostic tests can be carried out online. Students are able to monitor the status of variables and can also perform web-based SCADA using viewON. An additional advantage, which is of great value when teaching equipment is operated by a large number of students.


Additional training and educational possibilities

Another educational feature provided by the use of the eWON in conjunction with eCatcher and Talk2M is that it provides the teachers with remote access from outside the work center and this allows them to develop and test new practical exercises, to monitor the system’s operational status or other aspects that can be analyzed as required.

But the principal advantage, apart from the students’ acquisition of knowledge about the advantages and techniques of remote-controlled automated systems and skills in operating them just by using the eWONs, is that the combination of the training equipment and the remote control devices enables distance learning. At the City of Béjar Professional Training Centre, they are now working on a project to provide students with classroom-based/distance practical exercises so that they can make a booking to use the training equipment outside the center's usual opening times.
