Traditionally, process plants were deployed with point-to-point wiring, custom, multi-pair homerun cables and large complex marshalling cabinets with hundreds or sometimes thousands of termination points. Deploying remote I/O in large-scale plants can deliver major positive impacts thanks to easier installation, simpler serviceability and reduced cabinet space. Jesse Hill, process industry manager at Beckhoff Automation USA, recently talked with Control’s editor-in-chief, Len Vermillion, about the many benefits of remote I/O, including enhanced physical layer diagnostics, wiring reductions, lower cost, and increased flexibility in plant network topologies.
