[Process Analyst] Trend export to CSV freezes Runtime window

Anton

Citect 7.50 on one of my site computers (Win7 32-bit, core i3, SSD - B&R panel PC) has a trouble: when I try to export more than 4 pens Runtime window freezes (white square). On my virtual machine (my developer station) I have never been see this troubles with export.

In the Citect help I see a parameter [Trend]CacheSize3    - can it help in my situation (if increase it from 764 to 65536) ????

  • Hi Anton,
    The API is likely the same. Both would be calling TrnQuery at the lowest level to extract the information. But both could use different parameters.
    It would be worth testing TrnExportCSV to see if it causes the same hang/freeze.
    You could also enable Kernel Watchdog to create a crash file, which could be analysed by AVEVA support.
    Kind regards
