retrofit, legacy system, methodology, Industry 4.0, step-by-step
Abstract
Concepts such as "legacy system" and "brownfield system" emerge in the field of industrial automation and manufacturing, referring to older systems that can be updated or integrated with new technologies through a process called "retrofit". This process is aimed at improving the performance, connectivity, and integration of old systems with new technologies or processes. Therefore, it is necessary to discuss and define the appropriate technologies and techniques for implementing the retrofit on the legacy system. The goal is to present an efficient and economical legacy system update proposal that meets the needs for communication and integration with other systems, as well as the demands of the modern industry for the use of complex technologies and process integration.
