A few settings determine weither data values for a variable should be logged into the time-series database (TSDB) or not. By default they are all set to enable logging.
Field
Active
in theOPC UA Server node settings
dialog window should be checked. This dialog window can be opened by selecting server’s node in theAddress Space
panel and clicking onEdit
button.

Setting in the column
Log to TSDB
of theLogged Variables
table should be checked.

For those variables for which all these conditions met, ogamma Visual Logger for OPC creates subscriptions and monitored items on OPC UA Server, and writes received data changes to the TSDB.
