Slava Filimonov & Jim Cook, PVSS - ROOT Interface Introduction Interface that allows PVSS data to be displayed using ROOT, permitting all analytical functions that are available in ROOT Motivation Features and implementation of the interface Examples – including demonstration Future plans 14.04.2005 Slava Filimonov & Jim Cook, PVSS - ROOT Interface

Slava Filimonov & Jim Cook, PVSS - ROOT Interface Motivation Limited PVSS functionality Zoom impractical Histogramming difficult to use Exclusively data from PVSS No possibility to fit curve NOTE: This has been and is being improved Physicists familiar with ROOT ROOT is a very powerful analysis tool Possibility for parallel data sources Multiple PVSS systems Could include DAQ data, for example This is not implemented in the current version 14.04.2005 Slava Filimonov & Jim Cook, PVSS - ROOT Interface

Slava Filimonov & Jim Cook, PVSS - ROOT Interface Basic features Based on TCP/IP Any number of ROOT clients can connect to one PVSS project Trend Plots: From a specified time in the past to present (updating) From a time in past to another time in past (since--until) Histograms ROOT Macros can be used No configuration necessary on PVSS side Windows and Linux 14.04.2005 Slava Filimonov & Jim Cook, PVSS - ROOT Interface

Slava Filimonov & Jim Cook, PVSS - ROOT Interface PVSS TCP Manager Pass data point names or aliases using pattern (dpNames) Take data for defined period and pass to a client (dpGetPeriod) Send data on change (dpConnect) Send single datapoint value (dpGet) Currently limited to integer, float and boolean Standard PVSS functionality used 14.04.2005 Slava Filimonov & Jim Cook, PVSS - ROOT Interface

Class Structure ‘Normal’ trend Histograph Retrieve single value Retrieve DP names with pattern Display data from start time to end time Trend with 2-dimensional ‘surface’ Display data from start time and update 14.04.2005 Slava Filimonov & Jim Cook, PVSS - ROOT Interface
