DISTRIBUTED AUTOMATION SYSTEM

Abstract

A distributed automation system is described with at least one first order network device (1, 1′, 1″) and at least one piece of data available on the first order network device, at least one database system (2) and at least one first order network (3). With the distributed automation system, the data acquisition and diagnosis possibilities are improved by the first order network device (1, 1′, 1″) and the database system (2) being directly interconnected via the first order network (3), and by the data from the first order network device (1, 1′, 1″) being able to be transmitted actively and directly via the first order network (3) to the database system (2).
