Experiences in Different Fieldbuses Used together with PC-Based Control Systems
This paper deals with experiences about three different fieldbuses based on a comprehensive research study in the field of PC-based device and system control (soft PLC). The research has been made in Tampere University of Technology at the Institute of Production Engineering. The overall reaction time of PC-based control systems has been tested so that the delay caused by fieldbus is included. For the end user this is the reaction time that counts. The paper discusses also some topics concerning motion control and a case study of an application controlled by soft PLC.
