Active Infrastructure for Ethernet-APL

Diagnostics and fiber optics for successful project execution

Ethernet-APL enables a network infrastructure for seamless access from hazardous areas to the control or board room – providing insights into production quality and status. It is a flat and reliable technology with high data throughput that enables users to access the information of highly diagnosable and configurable devices.


Via the Ethernet-APL field switch from FieldConnex multiple applications can simultaneously query information from the field. An extra layer of diagnostics about the physical layer itself enables personnel to detect and eliminate errors or creeping quality degradation in the installation. It can be simply stated that diagnostics with Ethernet-APL technology assist users in maintaining production quality and uptime. The switch reports physical layer measurements even for fiber optic transmission.

Especially designed SFP modules connect the switch to the network via single-mode and multimode fiber optic cables, supporting cable lengths of up to 30 km. They are certified as an accessory to the switch for installation in Zone 2/Div. 2.

Pepperl+Fuchs presented the latest infrastructure products for any signal type, from intrinsically-safe barriers and Remote I/O to fieldbus and Ethernet-APL to a highly interested audience at Hannover Fair 2024. The experts from the company provide guidance to planners and end users along the path to digitalization in the field of their process plants.
