PI OPCtoCSV Tool: Filter by OPC ItemID
The PI Interface for OPC DA is packaged with the PI OPCtoCSV tool which extracts all OPC Items. It is possible to filter the items by subbranch like the PI APS Connector for OPC DA interface, but unlike the APS Connector, it is not possible to filter by OPC ItemID using the PI OPCtoCSV tool.
We have an OPC server with around 20k items that we read into PI, however, using the OPCtoCSV tool it takes 12 hours to extract about 2k of these PI tags and 200k other OPC items that we are not interested (mostly just metadata). Filtering by subbranch does not help because it recurses all sub-subbranches. If we could filter by OPC itemID we would be able to filter on only the items we are interested in and hopefully the OPCtoCSV tool will run faster.
