OPC UA Server Historical Access

[golubyatniks]

Hello,

Does WinCC OA OPC UA Server support UA HA (Historical Access)?
Is this feature avaliable in 3.15 Version?

According to the WinCC OA Documentation the WinCC OA OPC UA server/client support the following functionalities:

The OPC UA Client supports:

OPC UA Data Access (DA)
OPC UA Alarms & Conditions (AC)
OPC UA Historical Access (HA)

The OPC UA Server supports:

OPC UA Data Access (DA)
OPC UA Alarms & Conditions (AC)

For details please have a look at the WinCC OA Documentation.

Thanks a lot.

I've seen this information, but also met following info at 3.16 Release notes:

As OPC UA is getting more and more important, it is also possible to connect to OPC UA Historical Access now.

Do you know, is this about Client protocol or about Server?

I had a look at the Documentation for 3.16 P007.
In the documentation you will find the following information:

=======
OPC UA Server

Historical Access

The WinCC OA OPC UA server now supports the Historical Access functionality and enables clients to access historical data.
