Class: opc.hda.Data
Namespace: opc.hda
Intersection of time stamp in OPC HDA data object
Syntax
NewObj = tsintersect(DObj)
Description
NewObj = tsintersect(DObj)
resamples data in OPC HDA data
object DObj
so that all elements of the object have the same time
stamps given by the intersection of all time stamps in all elements of
DObj
.
If DObj
contains elements with the same item ID, those elements
are combined into one element. So the size of NewObj
might be
smaller than the size of DObj
.
Examples
Load the OPC HDA example data file and find all common values of
hdaDataSmall
:
load opcSampleHdaData;
newObj = tsintersect(hdaDataSmall);
Display the values and qualities of the new object:
newObj.showValues
