Ethernet-APL is simple, fast and digital

Ethernet to the field

Bringing Ethernet to the field is possible with Ethernet-APL

Process plants strive for efficient engineering and plant design. It is important to achieve a fast start-up and commissioning and to produce with efficiency and quality. Digitalization 4.0 uses valuable data from the field level for optimizing processes. Field level connectivity and data access are crucial. So far, there were limitations such as low speed, limited bandwidth and defined protocol conversions. An Ethernet technology meeting the requirements of process plants is beneficial.

Ethernet-APL in a chemical plant

The leading standards organizations worked together with major industry partners like Endress+Hauser to specify an advanced physical layer for Ethernet which meets the requirements of process industries. Ethernet-APL is designed to be open, future-proof and ready for the Industrial Internet of Things (IIoT).
