TECHNIQUE FOR DETERMINING PERFORMANCE OF INDUSTRIAL PROCESS CONTROL

摘要

A technique for determining performance of industrial process control is provided, wherein local controllers of the industrial process are coupled via a wireless communication network to a central controller and supervised by a supervisory system that captures operational information from the local controllers. A method implementation of the technique comprises receiving first event records captured from the wireless communication network, receiving second event records captured from the supervisory system, correlating at least the first and second event records that pertain to substantially the same period of time in a correlation record, and determining a performance indicator on the basis of information included in one or more correlation records.
