Some troubleshooting steps that may be helpful in this situation.
You said "no error shows up". An important distinction is where you are referencing that statement from? The ACE node or the PI Data Archive node?
- If the ACE node, look to see if there are any messages on the PI Data Archive node because those would be more indicitive of a write issue.
- If on the PI Data Archive node, then that means either:
a. the connection isn't making it to the PI Data Archive node (unlikely since you say you are getting "saved PIACEPoint references")
b. the connection from PI ACE is being given privledges that do not have write permissions. In this case no errors are thrown and the values that are attempting to be written are just dropped. Check in Network Manager Statistics to find out what sort of privledges a particular conneciton has.
c. the compression settings may be set in such a way that you aren't seeing the data you intend
This is also not considering buffering. If buffering is enabled then you will have to look for a connection from that on the PI Data Archive rather than PI ACE.
Thanks for giving very useful tips that will be handy for troubleshooting.
The issue is resolved when instead of using
arrMappings(cntWellTag, 1) = New PIACEPoint(Context, node.Attributes.GetNamedItem("Choke").Value(), TagAliasUsedType.TagAliasAsInput)
tmpPIACEPoint = New PIACEPOINT()
tmpPIACEPoint .SetTag(Context, node.Attributes.GetNamedItem("Choke").Value(), TagAliasUsedType.TagAliasAsInput)
tmpPIACEPoint .SendDataToPI= true
I am still working on it but I guess we need to set SendDataToPI=true at the the time of PIACEPoint initialization in InitializePIACEPoints().
