It is the task of collecting the data of each device or equipment in one place and making them meaningful for the purpose of system integration (SI) or data integration. Previously, there were groups of devices that introduced integration protocols such as GBIB, but there is a problem that is limited to measurement devices. The use of machines, devices, and equipment is long, but the need to use such data is increasing, and it is time to have a system that integrates data from the field. It is necessary to collect the current data and provide information to all the persons involved in the manufacturing process of the site manager and further to identify the problems of each process and to create a basic data which can make an effort to improve it. In addition, carmakers are advising subcontractors to introduce such systems as part of overall quality control.
