System and method for providing context-adaptive resolution for industrial control system data

A method, comprising:

• receiving, by an embedded historian device of a control system, input data from a data producer at a first resolution;
• storing, in a memory of the embedded historian device, the input data at the first resolution;
• computing, by the embedded historian device, output variables based on the input data;
• publishing, by the embedded historian device and to a local historian device, time-series data of the output variables using a local network link at a second resolution, wherein the second resolution is lower than the first resolution, wherein the local historian device is configured to publish, to a central historian device, the time series data at a third resolution, and wherein the third resolution is lower than the second resolution, and wherein the local historian is configured to store the published time-series data of the output variables at the second resolution;
• identifying, by the embedded historian device, an event when the output variables meet a set of conditions;
• and
• publishing, by the embedded historian device and in response to identifying the event, a portion of the time-series data, for a subset of the output variables, at the first resolution, wherein the portion of the time-series data includes at least data obtained prior to a time of the event, wherein the local historian device is further configured to re-publish, in response to identifying the event, a portion of the stored time-series data at the second resolution, and wherein the central historian device is configured to:
• receive, from the embedded historian device, the portion of the time-series data published at the first resolution;
• receive, from the local historian device, the portion of the time-series data re-published at the second resolution;
• and
• merge the portion of the time-series data published at the first resolution, the portion of the time-series data re-published at the second resolution, and the published time series data at the third resolution, wherein the merging forms adaptive resolution time-series data.
