Ethernet-APL Proves its Value: Fourth Multi-Vendor Test 

July 10, 2025

Expanded testing shows broad industry adoption

Ethernet-APL has moved beyond readiness. The instrumentation manufacturer Endress+Hauser successfully conducted another set of load tests of a realistic PROFINET over Ethernet-APL setup. Two years after the last successful multi-vendor tests, the technology has proven its strength again in a realistic simulation.

The load tests were tailored to meet customer-specific requirements, demonstrating that components from various manufacturers can seamlessly work together to build a robust and reliable system based on PROFINET over Ethernet APL. Requirements were defined from the end-user perspective by the global chemical company BASF. On the supplier side, devices from Endress+Hauser, Pepperl+Fuchs, R. Stahl, Phoenix Contact, and Samson were integrated into an Emerson control system and their interoperability was confirmed.
