Field device performance verification, process element alignment determination method and process element alignment device in process control system supported by big data

摘要

PROBLEM TO BE SOLVED: To determine the alignment of process elements in a process control system.SOLUTION: A technique for determining unit-specific information such as performance verification data describing a process unit installed in a plant, place information, images, and other data includes acquiring unit-specific information in a local device during the performance verification of the process unit. The local device may determine, on the basis of this information, the relative order of process units in a process flow, and determine a process element alignment map indicating the activation order of a plurality of process elements in a flow. A user may correct the map of the local device. The unit-specific information and/or the map may be utilized in the local device for generating the expression/examination of a process flow. The user may take an enlarged or contracted photograph of these examinations for further sophistication or for simplification.SELECTED DRAWING: Figure 5
