Migration Strategy toward Innovative, Digitalized, and Harmonized Production Systems

Quo Vadis Industry 4.0? Position, Trends, and Challenges

“…In the ICPS context, this need for interoperability emerges from the difficulties of integrating data from various sources and services that can understand each other's semantics, across the different layers of RAMI 4.0. Additionally, the migration process conducting to the integration of legacy systems, both at Operational Technology (OT) as well as Information technology (IT) and between them, assumes crucial importance for the operation of such systems, e.g., PLC, RC, CNC, databases, SCADA (Supervisory Control and Data Acquisition), and MES (Manufacturing Execution System) systems [41].…”

“…The establishment of best practices, especially those linked with credible migration strategies, are needed to support the industry transition from their traditional rigid and centralized production systems towards the new decentralized, autonomous, and intelligent ICPS infrastructure. This migration should be an evolutionary process based on the continuous, phased, and smooth transition of existing systems and not a disruptive process, to preserve investments that are already done in brownfield infrastructure [41], [44]. However, greenfield investments to new infrastructures offer a unique opportunity to avoid the complexities of migration and focus on cutting-edge technology, which, however, bears the potentially higher risk and cost.…”
