Exception Handling in S88 using Grafchart

Rasmus Olsson, Karl-Erik Årzén

Abstract

Exception handling constitutes a large part of the design and implementation effort in batch production, but so far little work has been carried out to specify this area. This paper proposes an internal model approach for equipment unit supervision using Grafchart. It also discusses exception handling at the recipe level.
