AVEVA Edge Storage of Data

Question

Good day 
 Please can you advise if the AVEVA Edge can store and recall data on flat files similar to that of the InTouch, 
 If so, what are the limitations in regard to: 
 
 Number of tags 
 Retrieval rate 
 Disk size 
 
 Thanks

AVEVA Edge has similar to InTouch "LGH" files, in Edge they are called "HST" and configured from the "Trend Logger" configuration. In the trend logger, you have several formats,

Proprietary, uses the HST file format on the hard disk
 
 Note the HST file is not "humanly readable" but you can use the HST2TXT function to turn it into a CSV file

Database, uses any SQL database 
 Historian, uses either AVEVA Historian or AVEVA Insight 
 
 The Trend Logger worksheets can have up to 1000 tags per work sheet, and a project can have up to 999 different trend worksheets. 
 Rate will depend on hardware.
