Does Ethernet-APL replace existing fieldbuses like PROFIBUS PA or Foundation Fieldbus?

In the long term, yes. Ethernet-APL offers much higher bandwidth and seamless Ethernet integration. Migration strategies and gateways enable a gradual transition and protect existing investments.

Can I reuse my existing two-wire cables?

In many cases, yes. Ethernet-APL is designed to run on existing fieldbus cabling (Type 'A'). A review of cable quality and length is needed upfront.

Which field devices already support Ethernet-APL?

The number is growing steadily. Leading vendors already offer sensors and actuators with APL interface for pressure, temperature, level, and flow.

What is Ethernet-APL?

What is it?

Ethernet-APL (Advanced Physical Layer) is a new physical layer for Ethernet communication, developed specifically for the process industry. It transmits data (10 Mbit/s) and supplies power over a single standard two-wire cable over long distances (up to 1000 m) — intrinsically safe for hazardous areas.

Why does it matter?

Ethernet-APL overcomes the last obstacles to digitalization in process automation. It enables seamless, protocol-independent communication from enterprise to field level, simplifies installation, enables extended device diagnostics, and lays the foundation for IIoT applications.
