A programmable logic controller is disclosed that filters and presents to
a user data that conforms to a hierarchically structured data model. The
programmable logic controller through utilization of an input component
that receives data and a filter component that filters the data based at
least in part on one or more filtering criteria is able to extract data
that is relevant to an individual user's needs and/or requirements. The
filtering criteria utilized by the filtering component can include
passwords and group affiliations as well as the user's biometric and/or
anthropometric information. The claimed subject matter further relates to
a component that can be utilized to provide a similar filtering
functionality with respect to legacy programmable logical controllers,
and legacy industrial automation devices.
