Abstract

The invention includes a method for monitoring an automated plant having at least one field device, wherein a first cloud-capable database, having a first data configuration and containing field device related data including measured values, parameter values, identification data, and diagnostic status of the field device, wherein a second cloud-capable database having a second data configuration incompatible with the first data configuration, and wherein the first and the second data configurations define file formats of the data, the method comprises: retrieving at least a part of the data contained in the first database by means of a data conversion unit, especially an edge device or a gateway; converting the retrieved data into a format conforming to the second data configuration; and storing the converted data in the second database. The invention further includes a data conversion unit, which is embodied for executing the method of the invention.

First claim

The invention claimed is:

1. A method for servicing an automated plant in which a first field device is applied, comprising:
providing a first cloud-capable database having a first data configuration and containing field device related data including measured values, parameter values, identification data, and diagnostic status of the field device;
providing a second data conversion unit;
collecting the field device related data from the first field device via the second data conversion unit;
transmitting the collected field device related data to the first database;
storing the collected field device related data in the first database;
providing a second cloud-capable database having a second data configuration different from the first data configuration, wherein the second database is connected for communication with a second field device of a second automated plant, wherein the first and the second data configurations define file formats of the data, including semantics and rules for organizing and for storing the data in the first and second databases;
providing a first data conversion unit including an edge device or a gateway;
retrieving data contained in the first database via the first data conversion unit;
converting the retrieved data into a format conforming to the second data configuration;
transferring the converted data to the second database via the first data conversion unit;
storing the converted data in the second database;
accessing the data of the second field device by means of an application of the second database; and
servicing the second field device using the field device related data of the first field device retrieved from the second database, wherein the servicing includes parametering the second field device and querying and visualizing process data and diagnostic data of the second field device.

2. The method as claimed in claim 1 , further comprising:
retrieving via the first data conversion unit at least a part of data contained in the second database not contained in the first database;
transforming the retrieved data into a format compatible with the first data configuration; and
storing the converted data in the first database.

3. The method as claimed in claim 1 , wherein the data located in the first and the second databases are synchronized in such a manner by the first data conversion unit in recurring, defined time intervals, that after termination of a synchronizing procedure the databases have essentially equal data.
