METHODS AND SYSTEMS FOR PROVIDING DATA FROM AN INTERNAL DATA PROCESSING SYSTEM OF AN INDUSTRIAL PLANT TO AN EXTERNAL DATA PROCESSING SYSTEM

A method for providing data from an internal data processing system (IDP) of an industrial plant (PL) to an external data processing system (EDP), wherein the internal data processing system (IDP) comprises at least one industrial edge device (ED1, ED2, ... EDn), at least one industrial machine (IM1, IM2, ... IMn) and at least one data processing module (DPM), wherein the at least one data processing module (DPM) is provided with a user-defined data filter (DF) and wherein the method comprises following steps- generating a plurality of data packets from data related to the at least one industrial machine (IM1, IM2, ... IMn) by means of the at least one industrial edge device (ED1, ED2, ... EDn), and- signing each data packet (DP1, DP2, ... DPn) of the plurality of data packets with a first digital signature (PR1), in order to produce a plurality of signed data packets,by means of the at least one industrial edge device (ED1, ED2, ... EDn) ;- reading each signed data packet of the plurality of the signed data packets and, while reading, applying the user-defined data filter (DF) to it;- letting through those signed data packets that pass the user-defined data filter (DF) or rejecting those signed data packets that fail to pass the user-defined data filter (DF), by means of the data processing module (DPM);- sending all those data packets that have passed the user-defined data filter (DF) towards the external data processing system (EDP).
