This paper presents an algebraic approach to the specification
and verification of distributed technical systems, which are
controlled by a central control program. The approach is
demonstrated by its application to the case study "production
cell". The approach uses first-order specifications to describe
the possible behaviour of the system. Specifications are
structured according to the physical structure of the system. A
PASCAL-like program is used to enforce intended behaviour.
The whole case study, including specification as well as
verification of lifeness and safety conditions, is carried out
using the KIV system.
