  SwissFEL, the new Free-Electron Laser facility is a 740 m long accelerator with the goal of providing pulses of light between 6 and 30 fs long at a wavelength of 1 to 7 Å at 100 Hz*. To support shot-to-shot photon diagnostic* and link the measurements to other measurements along the machine that belong to the same machine pulse, a new triggering and data acquisition system was developed. A new protocol was introduced which allows deterministic triggering, configuration and data transfer via one full-duplex optical connection. The measurement data is stamped with an unique pulse identifier, delivered from the SwisFEL Timing System**. A readout and control interface was developed to support data delivery to the Data Acquisition Dispatching Layer* and for controlling the system.
