Introduction to PV log

The APS maintains a web-based log of many EPICS PVs values.

The webpage below is used to plot one (or more) of these PV values for a selected time range.

* http://www.aps.anl.gov/Accelerator_Systems_Division/Operations_Analysis/logging/11BM.html

Values are recorded every ~ 5 mins, and are saved for the last 7 days.

Follow these steps to view plots of historic values,

  • click on the desired PV name(s) in the Control Name / Readback Name panel
  • select the Date/Time Range of Interest
  • finally click PLOT.
