In cooperation with our commercial partner we are investigating the newly available deterministic Ethernet technologies like "Time-Sensitive Networking" with several IEEE 802.1xx standards. Early TSN implementations in embedded controller boards and switches were obtained in a test installation in autumn of 2018 to study feasibility, e.g. the required timing precision using PTP (resp. IEEE 802.1AS-Rev) to realize a "one-wire-ACS" based on Ethernet only for deterministic data transfer and message based triggers for synchronized ACS functions. We will report on our test bench experiences.
