✦ Synopsis

Based on a general design model for distributed control systems, and using standardised languages of IEC 1131-3 for control, three approaches to programming are investigated. The first is based on IEC programs with extensions, the second is a decomposition of programs with SFC notations and the third approach uses function blocks corresponding to the IEC TC65 Function Block Standard. The approaches are specified and compared, and conclusions for their use and tor further work are drawn. The intention of the contribution is to discuss possibilities tor open programming models, rather than to present final results.

In this paper, we discuss our proposal of a distributed database system, DB-MAN (distributed database system based on DataBase Migration in ATM Networks), which takes advantage of database migration in virtual local area networks (LANs) of ATM networks. DB-MAN has two notable mechanisms: a mechanism
