Industrial plant monitoring

An industrial plant system comprising:

• a first processing layer and a second processing layer, the first processing layer being communicatively coupled to the second processing layer, and the first processing layer and the second processing layer being configured in a secure network comprising at least two security zones delimited by firewalls, wherein at least one industrial asset is configured to communicatively couple to the first processing layer, wherein the asset is configured to provide asset data to the second processing layer via the first processing layer, the plant control system further comprising an interface to an external network, wherein the second processing layer is configured to:
• generate technical context data related to the asset;
• and
• provide the technical context data to the interface, wherein the technical context data comprises at least one accessibility criterion for the asset data, the accessibility criterion comprising at least one rule and/or parameter compliable by an external processing layer for receiving the asset data;
• generate at least a first partial request for accessing the asset data;
• measure at least a first response to the first partial request, the first response being indicative of the impact of the first partial request on at least one computational and/or network resource;
• and
• determine, dependent upon the first response, at least a first iterative parameter, wherein the technical context data is at least partially generated using the first iterative parameter.
