Abstract
The superconducting stellarator Wendelstein 7-X (W7-X) started plasma operation in December 2015 after the commissioning phase of the machine. The main technical and diagnostic systems have been finished successfully. The timing system is an important part of the control, data acquisition, and communication systems of W7-X. The first version of the trigger-time-event (TTE) system is in routine operation at the W7-X experiment. Since 2004, it has been used for the commissioning of the control and data acquisition components and also for the stellarator WEGA. The commission of the second version of the TTE-system is still on-going and planned to be finished at the end of 2016. Starting with an introduction of the TTE-system of W7-X, this contribution describes the main features of the TTE-system. The actual state of the TTE-system and the network topology will be presented. Finally, the first experiences of W7-X operational phase OP1.1 related to the TTE-system are discussed.
