Fieldbus Network Migration and Cable Reuse are Key Requirements for Modernizing Industrial Facilities to Ethernet

The installed base of fieldbus networks are engineered to operate reliably in the specific applications and environment for which they were designed. Serial product and infrastructure obsolescence, limitations in scalability, and the loss of highly skilled support for production facilities all have become high Pareto challenges for facility and network managers wanting to upgrade to industrial Ethernet. In this product application note, PCN introduces IP-485, a proven approach to the modernization of serial-based fieldbus networks, and describes how Ethernet-over-RS-485 products can be deployed to easily, securely and cost effectively transform existing fieldbus network infrastructure into one that also simultaneously transports standards compliant industrial Ethernet networks.
