Re: How to configure Trend With Historical Data of 1 month in Trend Parameterization
If you want to show historical data in the trend you have to configure archiving for data.
At the dp-element you have to add and configure an _archive config. When the archive config is configured you have to ensure that the archive/RDB manager is running (depending on the type of archiving used in the project).
In case of RDB archiving you need an Oracle database and the WinCC OA system must connect to the system.
For detailed information please have a look at the WinCC OA documentation:
-- Module PARA --> Data point configs --> _archive
-- System Management --> Database
If you want to show "real time data" in the trend you have to take into account that displaying a time range of 30 days will possibly show a lot of information.
E.g. if the value changes every 5 seconds you will have about 520.000 value for 30 days.
