How to read OPC Quality using Datadirect with 800xAHistory
We have a requirement in Datadirect reports, when the OPC quality is "Bad" or "Uncertain" corresponding value has to be show as "null" in reports instead of last good value.
When we try read the OPC Quality using Datadirect with the dataformat = 32, we are getting only process value in single column not an OPC Quality.

Please suggest if any other option available ?

you selected 32 as you want to see data quality.
When you open the Inform IT Options menu (ie the Datadirect settings), you have a tab called Data Format, and there Default Data Options. Is History Data Quality checked, and if so, which of the radio buttons Symbolic/Numeric/Red coded ?
