Looking for guidance in fast data trending, historical trending, and export to Excel without losing resolution.
PLC tags to trend (OPC): 15 Calculated tags to trend (Exprension): 5 Scan Class for all tags: 10msec Historical scan class for all tags: 10msec
What is the best method to collect the data at the desired rate, display the historical data with millisecond resolution, and export to Excel with the same millisecond resolution?
To date I have just used tried using Easy Chart to view realtime and historic data but cannot find how to achieve msec resolution. And exporting to Excel from Easy Chart only provides seconds resolution.
Do I need to change settings for trending tags or historical tags?
Would Reporting module provide me what I’m looking for?
All suggestions appreciated.
