Ethernet-APL Smart, fast, digital

The 2-wire data highway for endless possibilities Ethernet-APL combines the benefts of simple and robust 2-wire technology with the benefts of Ethernet, enabling top-performance and seamless data access in the feld of process plants.

2-wire cable with 10 Mbit/s full duplex communication

Advantages • Ethernet technology in combination with well-estab lished Industrial Ethernet Protocols like PROFINET • High-speed communication and remote access to the field shorten commissioning time • Seamless access to the data and algorithms of smart instruments (e.g. Heartbeat Technology) exploits the full potential of instrumentation

Explosion protection for all zones and divisions

Benefits • High plant availability and increased production output with less plant shutdowns

• Increased efficiency in maintenance • Plant downtimes can be minimized
