From Freelance 7.1 to Freelance 2013 upgrading Trend Server is running, biut no trend data.
If any one can check / guide to solve this issue.
Please check few things,
Time synchronization is enabled, DigiVis and controllers are in time synch ?
Incase timesynch not enabled and enabling from configure tool, note that DigiVis and CBF should be closed while enabling time synch, or need to restart digivis/CBF once after enabling timesynch.
Is trend values via Trend acquisition block are coming ? but trend values via trend gateway are not coming ? in that case check trend gateway is downloaded with latest changes ? and following to gateway digivis is downloaded ?
OPC item list is synchronised ?
If trend values are via trend gateway, you can see same value in graphic?
Please get back if not resolved...
It seems You have a typical problem with Trends - the time in Your controllers and stations is not synchronized. You DO get the data, only You can't see them, as they are shown with different timestamp.
Please do the following:
1. If You didn't enable time sync as Sumit wrote above, do it now!
2. Then set Your systems Time Master time with CBF (go online->chose Options menu->Set system time)
3. Check if system time was set properly (see controllers .DateTime variable)
4. Check if time is synchronized across the system properly
For now try the above. If You did it and have the same time in all stations and still do not see trend data, give us a feedback and we will go deeper into this problem.
Hope it helps,
