Foundation fieldbus-based laboratory: A case study of Harmonas-DEO system

This paper presents a Foundation Fieldbus-based laboratory for education of automation infrastructure. Design and implementation of a level-control plant model using multi-vendor field devices is proposed. Harmonas-DEO fieldbus system is described as an illustrative case study for configuring and commissioning fieldbus segment, defining control strategy, designing human machine interface (HMI) screen, and troubleshooting. Fieldbus control valve diagnostics based on the use of Valstaff are also included.
