DeviceReadTimeSeries

DeviceReadTimeSeries[device,{t,dt}]

repeatedly reads default items from the specified device at interval dt for a total time t, returning a time series of the resulting values.

DeviceReadTimeSeries[device,{t,dt},param]

repeatedly reads the parameter param and returns a time series of its values.

DeviceReadTimeSeries[device,{t,dt},{param1,param2,…}]

repeatedly reads the parami and returns a time series of their values.

Details

  • The time parameters dt and t can be Quantity objects containing units. If they are given as pure numbers, they are assumed to be in units of seconds.
  • DeviceReadTimeSeries is a blocking function that does not return until it has collected data for time t.
  • A device can be specified either by a DeviceObject or by a string representing a device class.
  • A component of a TimeSeries object ts corresponding to parami can be obtained from ts["PathComponent",i].
  • For string parameters, a component can typically be obtained from ts["parami"].
