In this paper we describe how to generate a large set of restart points for a sequential control program, thus enabeling fast restart of a plant after a fault and subsequent repair. This is work in progress, and will recapitulate the main idea as developed in the Aramis project, and discuss its applicability to the programming languages defined by IEC1131-3.
