TwinCAT Analytics

When using the "TwinCAT Analytics" memory type, a binary file is written as memory, the format of which corresponds to the TwinCAT Analytics data format. Although this has no relevance for the OPC UA client (as it accesses the historical data via OPC UA), it does open up interesting possibilities for further use of the historical data, as you can read the binary file into the TwinCAT Analytics Toolchain and process it there.
The following diagram illustrates this relationship.

TwinCAT Target Browser

If you use the TwinCAT Analytics storage format in your Historical Access configuration, you can also get the stored values via the TwinCAT Analytics Toolchain, for example the TwinCAT Target Browser. To do this, add the directory that you have defined in your configuration for saving the historical values in the TcAnalytics File tab of the TwinCAT Target Browser. The saved values are then displayed as records in the usual TwinCAT Analytics form and can be processed further.
