  The accelerator complex of the Swiss Light Source (SLS) is presently under commissioning at the Paul Scherrer Institute (PSI) in Villigen, Switzerland. The newly developed digital beam position monitor (DBPM) system has been successfully used to determine beam positions in the pre-injector LINAC, the transfer lines, the booster synchrotron and the storage ring. Instant and free selection of operation modes through the EPICS-based SLS control system allows to choose between single turn, turn-by-turn and closed orbit measurements. The operational experience and performance of the DBPM system is presented, based on measurements, taken during SLS commissioning. A monitoring system (POMS), which measures the horizontal and vertical mechanical positions of each BPM block in reference to the adjacent quadrupole magnets has been installed and first results, indicating transverse movements of the BPM blocks as a function of current in the storage ring will be presented.
