Abstract
A system for servicing field devices in an automated plant with a superordinated control/service unit, wherein the superordinated control/service unit accesses the field devices via a communication network. The communication network has at the control/servicing level a first bus system with a first transmission protocol and at the field level a second bus system with a second transmission protocol. The conversion of the two transmission protocols occurs in a gateway and provided in the gateway a basic software, which, upon the occurrence of an event, scans to ascertain the field devices arranged at the field level and utilizes the ascertained information concerning the field devices, in order to download the corresponding electronic device descriptions from an application server and to provide these to the control/service unit for servicing the field devices. The application server contains server apps.
