My Rapid Scada collects data in two ways, OPC DA and OPC UA. If I export the data in CSV format, some of the OPC UA channel attributes will be overwritten when I import the data. I have a lot of points in my system and need to modify the units, decimal places, input and output of these channels in batches. What I want to ask is whether there is a way to specify which channel to export when exporting the CSV file. I can’t choose it now.
