Data processing methods and systems are disclosed for use in industrial
control. The methods and systems may include receiving control data from
automation components of an industrial control system by a first computer
system, the first computer system being coupled to the automation
components by means of a first network, storing at least some of the
control data in a first database by the first computer system, performing
a database query of the first database for determination of a subset of
the control data, aggregating the control data of the subset, and
transmitting the aggregated control data to a second computer system over
a second network.
