Diagnostics for the veneer clipper

Abstract

The aim of this thesis was the renovation of the diagnostics program code of the rotary veneer clipper with Raute Oyj. Today's code was done fifteen years ago, so the reason is obvious. The main code, the safety mode, the call back functions, and visualization, which are already done, need the increase of the functionality. The thesis consists of issues of automation and electrical engineering. TwinCAT 3.1 and Microsoft Visual Studio are the most used programs in this project. The thesis includes theoretical and practical parts, software and hardware work, such as programming and emulating the possible equipment.

Besides the coding of the diagnostics for the clipper, I also need to learn other issues of the veneer preparation process so I could fully familiarize with the goals of the clipper and renovate it in the best way, combining the today's technologies and techniques.

Suggested ideas will increase the precision and reliability of the veneer clipper. Software changes mostly concern functionality and HMI details, increasing the efficiency and speed of reaction and maintenance actions. Hardware ideas are more about new interfered technologies and the way it can help the product lines.

The software programming samples are ready and presented in the thesis, hardware functions, although it is not possible to get and test practically, are explained and emulated.
