  Two important reasons led to the first developments for a new ACS for the HIT ion therapy accelerator complex: a) the first implementation of the ACS was done in 2003-2005 resulting in well-functioning, but mostly proprietary solutions more and more components of e.g. the specially built device control units (DCUs*) are becoming discontinued, thus a new realization using standard SoCs or similar is necessary; b) new functionality like multiple energy operation** should enhance the duty factor of the accelerator facility resulting in significantly higher patient irradiation efficiency. 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.
