Trending Solidify for longer time span

azam Javed

Hello community,

We have recently upgraded our wonderware InTouch application from v9.5 to Aveva InTouch 2023R2. 

We are facing problem in historical trends.

It shows data and historical trends very fine for short span. But if we set the graphs for longer span e.g more than 15 hour or 1 day span the trends automatically solidifies. 

All the settings and scripting are the same as before. 

No industrial graphics are being used. 

Sample Pictures attached

    Hey Azam, drawbacks of using legacy graphics in a modern Intouch 2023 R2 . Let me add a few things i would like you to try:

    1) Take a new machine, copy all this, delete all the .LGH files, create new one for say only 10 tags and see what happens 

    2) Whats the tag size of the application ? How many tags are being historized in .LGH ?

    3) I would highly recommend to use Industrial graphics, right now i have not established if its a graphic issue or .LGH corruption issue, what does the OCMC logs say, mark flags and try for longer span, see what happens

    4) Part of migrtaion, again recommendation  is to use Historian for data reliability, faster, better trend data 

    Lastly , i urge people not to do like for like migration, think about upgrade to innovate
