Process networking

Standardized communication networks are linking intelligent field devices to enterprise systems to offer unparalleled benefits to the process industries. Benefits include dramatic reductions in installation costs, reduced maintenance and commissioning costs and improved process performance. FieldLink, Stonel process networking products and support services program, facilitates the implementation of your field network. The following section describes how the FieldLink program can help you implement and optimize contemporary field communication networks for your specific application.

The two primary factors limiting fieldbus segment length are (1) the protocol communication limits and (2) the acceptable voltage drop. Each of the network protocols has network length limits that are published in the protocol details. It is also important to consider voltage drop with these networks.
