Process alarming in PID loop using foundation fieldbus with control in the field: A case study of DeltaV host system

This paper presents a software configuration guideline for process alarming in proportional-integral-derivative (PID) loop using Foundation Fieldbus (FF) with control in the field. Process alarm configuration of FF H1 segment installed in a level-control plant model and operated by the DeltaV host system is examined as an illustrative case study. Experimental results showing relations between alarm configuration and alarm notification of the studied system are included. The proposed practical guideline can be applied to develop a good fieldbus system alarm strategy for industrial processes.
