摘要

The invention relates to field management in industrial process systems and similar systems. In the invention, maintenance management systems of industrial processes of separate plants located geographically apart from each other are networked in such a way that they may communicate with each other and exchange information on maintenance parameters of field devices of different types. As a result, experience obtained in one industrial process can be transferred to other respective industrial processes and applications. By utilizing this globally collected cumulative information, it is possible to improve and specify the diagnostics of the separate local maintenance systems (6) essentially faster than in case if the local maintenance management system were independent and the diagnostics were changed on the basis of local experience only.
