Migration is Key to Upgrade Legacy RS-485 Serial Infrastructure to Ethernet/IP Networks
The install base of industrial RS-485 networks are engineered to operate reliably in the specific environments for which they were designed; closed and operating using a myriad of physical layer communications and language protocols. Product obsolescence, limitations in scalability of the infrastructure and potential loss of highly skilled support all have become high Pareto challenges to managers. In this paper, we introduce Ethernet over RS-485™ a new approach to modernization of industrial automation and distributed control networks and describe how it can be rapidly, reliably & securely deployed to cost effectively transform existing legacy RS-485 based industrial network infrastructure into one that can support IP-enabled devices while still supporting existing RS-485 networks & ensuring a managed migration to the "cloud" using existing paid for infrastructure.
