Abstract

PCT safety devices bring systems into a safe state when required. The devices used in them must be tried and tested in accordance with IEC 61511. It is often difficult to prove operational reliability due to a large number of heterogeneous data sources. Based on the revised NE 130, a solution to this problem has been. This includes an information model for the prospective structuring of PCT data and a concept for analyzing existing PCT documentation.
