VIDEO: Using distributed I/O in the plant
March 15, 2013 by Alison Dunn
A distributed I/O network can provide a universal and modular way to connect a wide range of signal input and control output possibilities. Hosted by journalist and industry expert Peter Welander, this video shows the benefits of using a distributed I/O network to send information between instrumentation devices in their and control elements in a control room or on a factory floor.
Connecting field devices to the network saves time and expenses associated with the installation and repair of wiring. The modular nature of distributed I/O networks makes it easy to add expand operations or integrate legacy process sensors. In addition, peer-to-peer systems are redundant, meaning that a break in a wire pair will not affect signal transmission.
