Ethernet-APL: The key to successful digitization in the field of process industries

Ethernet-APL enables operators to run a continuous communication network based on standard Ethernet right into explosion-hazardous areas. The Ethernet-APL rail field switch converts the standard Ethernet to a two-wire, twisted pair Ethernet where both power and data can be transmitted, which significantly streamlines the infrastructure and at the same time allows the connection of modern, intelligent field devices. These devices provide far more information than just their actual measured value: they can provide status data, perform self-diagnostics, and integrate seamlessly into asset management systems. Furthermore, Ethernet-APL enables data transfer rates of up to 10 Mbit/s, a significant increase compared to conventional fieldbus systems. At the same time, it supports cable lengths of up to 1,000 meters on the trunk or 200 meters on spur lines, thus also setting standards in terms of range. Ethernet-APL is therefore the leading technology for new measuring points or extensions to existing systems, paving the way towards end-to-end digitization and laying the foundation for predictive maintenance and transparent system monitoring.
