Abstract

A data transmission device remotely monitors and controls a distributed process system, which exchanges data with a superordinate communication unit via an interface and a communication connection in accordance with the IEC 61850 standard, and which is connected to a subordinate process via a further interface and a station bus. The data transmission device includes functional units integrated therein which are implemented as interfaces for connecting the process to at least one superordinate communication unit in accordance with the IEC 61850 standard.
