Computing resource management of Field Overlay Architecture for controllers

Efforts to effectively utilize field data over a wider area continue in the field of manufacturing systems. As part of these efforts, we focused on the computing environment for field devices, in which functionality can be expanded in a flexible manner for effective utilization of data. However, several issues remain to be resolved when new functionality is added to programs on various devices and multiple users operate the system concurrently. To resolve these issues, we introduce a computing environment for field devices called field overlay architecture (FOA) and describe the realization approach of the computing resource management of FOA.
