Good morning

Do you know how to change the setting of a variable to use the History Trend View?

I am using tia portal.

The current situation is that Historizing does not change to True and UserAccessLevel does not change to History Read.

Any help would be greatly appreciated.

And the Demo does not appear in the Adress Space - Root - Objects subfolder.

Hi,

when using TIA portal to configure the UA Server, please contact Siemens Support and ask if "OPC UA Historical Access" is supported in their UA Server. If supported, it should be described in their user manual. Most probably it is not supported at all.
