A recording cycle more than 1 hour can result in a wrong cycle when the moment is close after the time when the daylight saving switches to summer.
Description
In the Historian, a recording cycle of more than 1
hour leads to incorrect cycles if the recording time is shortly after
the changeover from standard time (STD) to daylight saving time (DST).
This behavior has been changed for
European Standard Time (CET) and European Summer Time (CEST).
In these time zones, switching to DST or back to STD has no
effect on the recording cycle any more.
To benefit from this fix:
- Update your zenon Software Platform to the
latest build of zenon 14 or higher.
Attention: In all other time zones, changing from STD to DST and
vice versa may still result in invalid recording times. This can happen if
the following conditions are met:
- Cycle time greater than 1 hour
- Cycle time smaller than one month
- Time
zone is outside CET/CEST
