I have system 800xA 5.1 FP4.
I have problem viewing the old data on the trend display. In the log configuration- data is stored for 1 year and collected every 10sec.
I am able to see the trace on the trend display for last 3 months but nothing before 3 months.
I did following setting on the trend display for a specific tag:
1. set the date-time to e.g. 01.08.2016
2. Logname set to 'Seamless'
3. treatment to 'momentary'.
But I dont get any data on the trend display. Can anyone please advice on what is the correct setting on the trend display to view the old data that is stored for 1 year?
