+# BLM NXCALS Property Pull
 
 Property pull is a Python project for the Cern's BLM section.
 It get precise data property for diamond devices by NXCALS and store it in lighter format on a MYSQL DB.
 In order to be used in other application.
 
+A routine script have been done in order to get the beamMode data
+from pytimber and pull the data accordingly.
+
+The final purpose is that it run daily on a server with a cronJob.
+
+An API may be develop in the future for precise data pull without DB writing.
+Meaning an instant return (JSON format) of data required.
