To monitor the position and stability of photon beams, X-ray beam position monitors (XBPMs) are installed in beamline frontends and beamlines for which the electronics infrastructure and its graphic user interface are described. Beam intensity fluctuations are calculated within different frequency ranges in order to monitor or study the photon beam stability. The calculation results are shown in the control system and saved in the archive system thus helping to monitor and analyze beam quality in real time or off-line. These XBPMs help to distinguish sources of beam motion and provide a tool to evaluate photon beam stability. Preliminary results will be discussed in this report.
