2.33 sddswget

• description: sddswget reads waveform process variables and writes the values to a binary SDDS file. Waveform PV names may come from an SDDS input file or from the command line. Each output page contains a single waveform with time stamps.
• examples: The following command fetches two waveform PVs and stores them in an SDDS file:
    sddswget -PVnames=rf:wave1,rf:wave2 waveforms.sdds  
  

• synopsis:
  usage: sddswget  
        [<inputfile> [-inputStyle={wget|wmonitor|automatic}] | -PVnames=<name>[,<name>]]  
        <outputfile> [-pendIOtime=<seconds>] [-pipe[=input][,output]]  
        [-provider={ca|pva}]  
  

• files: The output file contains parameters Time, TimeStamp, and WaveformPV along with columns Index and the waveform data.
• switches:
  • -PVnames=<name>[,<name>] — list waveform PVs on the command line.
  • -inputStyle=wget|wmonitor|automatic — choose how PV names are read from the input file. Wmonitor style expects a WaveformPV column; wget style uses a WaveformPV parameter.
  • -pendIOtime=<seconds> — EPICS connection timeout.
  • -pipe[=input][,output] — standard SDDS Toolkit pipe option.
  • -provider=ca|pva — select EPICS Channel Access (default) or PVAccess.
