	SwissFEL is a free electron laser user facility at the Paul Scherrer Institute in Villigen, Switzerland designed to provide FEL radiation at photon energies ranging from 0.2 to 12 keV. Beam commissioning of the hard x-ray line ARAMIS has started in October 2016 and lasing at 300 eV was achieved in May 2017. First pilot user experiments at photon energies ≥ 2 keV are foreseen for the end of 2017. This contribution comprehends commissioning results and first operational experience of various diagnostics systems, such as beam position monitors, charge and loss monitors as well as transverse profile measurements with screens, wire scanners and synchrotron radiation monitors. It also provides information about sliced beam parameters using a transverse deflector and shows first results from the BC-1 compression monitor and measurements with the electron bunch arrival time monitors.

	SwissFEL is free electron laser facility designed to produce FEL radiation at wavelengths from 0.1 to 5 nm. The beam commissioning of the hard X-ray undulator line ("Aramis") started 10/2016, and first lasing was observed in 12/2016. Presently, a 2nd undulator line ("Athos") for soft X-rays is being constructed, with 1st beam scheduled for mid 2019. In the injector, linac and beam transfer lines, 95 low-Q cavity BPMs operating at 3.3 GHz are used that were designed to support the future two-bunch operation mode with 28 ns bunch spacing and 100 Hz repetition rate. The undulator lines will only be operated with single bunches by means of a fast beam distribution kicker system, and were thus equipped with high-Q cavity BPMs operating at 4.9 GHz. The BPMs are not only used for beam trajectory optimization, but e.g. also for beam energy measurements (using standard cavity BPMs in the bunch compressors and beam dumps), beam charge and transmission measurements, or improvement of the performance of other monitors (e.g. wire scanners for profile measurement). This paper will report first operation experience with the BPM system, including a performance comparison of low-Q and high-Q BPMs.
