In this study, we have proposed the use of time-sensitive networking (TSN) technologies for the distribution of
the interlock signals of the machine protection system of the future IFMIF-DONES particle accelerator, required
for implementing the protection mechanisms of the different systems in the facility. Such facilities usually rely on
different fieldbus technologies or direct wiring for their transmission, typically leading to complex network
infrastructures and interoperability problems. We provide insights of how TSN could simplify the deployment of
the interlock network by aggregating all the traffic under the same network infrastructure, whilst guaranteeing
the latency and timing constraints. Since TSN is built on top of Ethernet technology, it also benefits from other
network services and all its related developments, including redundancy and bandwidth improvements. The
main challenge to address is the transmission of the interlock signals with very low latency between devices
located in different points of the facility. We have characterized our initial TSN architecture prototype, evaluated
the latency and bandwidth obtained with this solution, identified applications to effectively shape the attainable
determinism, and found shortcomings and areas of future improvements.Amiga-7 Grant
