Merging Data from one PI Point into another PI Point

Blog Post created by mfoerster Employee on Jul 13, 2018

I just needed to merge some data from one PI Point into another PI Point on the same PI Server.

 

Background:

The PI OPC UA Connector was running for a while before following the PI Connector Mapping Guide and routing the output of the OPC UA Connector to the previously OPC DA PI Points.

 

This Powershell script uses AFSDK to get the events from PI Point "sinusoid" and write these into PI Point "testtag" for the last hour.

 

[Reflection.Assembly]::LoadWithPartialName("OSIsoft.AFSDK") | Out-Null
[OSIsoft.AF.PI.PIServers] $piSrvs = New-Object OSIsoft.AF.PI.PIServers
[OSIsoft.AF.PI.PIServer] $piSrv = $piSrvs.DefaultPIServer
[OSIsoft.AF.PI.PIPoint] $piPoint = [OSIsoft.AF.PI.PIPoint]::FindPIPoint($piSrv, "SINUSOID")
[OSIsoft.AF.PI.PIPoint] $piPoint2 = [OSIsoft.AF.PI.PIPoint]::FindPIPoint($piSrv, "testag")
[OSIsoft.AF.Time.AFTimeRange] $timeRange = New-Object OSIsoft.AF.Time.AFTimeRange("*-1h", "*")
[OSIsoft.AF.Asset.AFValues] $piValues = $piPoint.RecordedValues($timeRange, [OSIsoft.AF.Data.AFBoundaryType]::Inside, $null, $true, 0)






foreach ($val in $piValues)
{
    Write-Host $val.Value " at " $val.Timestamp
   $piPoint2.UpdateValue($val,1)
}
