Into the Field of Process Plants with Ethernet

Pepperl+Fuchs shows first switch with Ethernet Advanced Physical Layer

Ethernet-APL will look familiar to users in process industries. It combines two well-known technologies: Ethernet for seamless, parallel communication – and robust two-wire technology combined with explosion protection for the field within the process plant. Ethernet-APL thus enables the digitization of the instrumentation.

Ethernet-APL upgrades network communications in this special environment. This standardization for Ethernet on the familiar two-wire cable, driven by twelve well-known suppliers, enables long cable runs, power supply and explosion protection with intrinsic safety as integral components. Ethernet-APL eliminates barriers to data flow, helping all stakeholders in the plant lifecycle to simplify designs, get plants up and running faster, keep them up and running better, and thus better manage risk.

With standardization complete, the technology is available to suppliers and users alike. The collaboration has also resulted in conformance tests to which manufacturers are subjected. This ensures interoperability and generates a high level of reliability. The first infrastructure components are available, such as the Ethernet-APL Rail Field Switch. This DIN rail-mountable field switch can be installed in Zone 2. The connections for field devices can be 200 m long and are intrinsically safe for Zone 2 (Ex ic). FieldConnex stands for highly reliable digital communication in the field of the process plant and first-class support from the experts at Pepperl+Fuchs.
