IPC diagnostics
If you have added a cyclic stream for the context of the IPC diagnostics, then this is not a cycle-synchronous stream, like a cyclic stream of the PLC. You can therefore specify a request interval in milliseconds at the level of the IPC diagnostics stream. The data is retrieved from the logger via ADS, buffered according to the data handling and sent.
You can use the Refresh button at the top right of the window to manually trigger this data retrieval process and display the current values in the symbol choice table.

As with the other streams, you can choose the symbols using the checkbox. Only the selected ones are collected and sent in the request interval.
