Hi,

has anyone been working on an Audit Trail solution when using WebVisu?  
Is it possible to retrieve the current username of each session - maybe this must be retrieved and written from the Visu- interface editor to get each session?

You can use the VisuUtils library to get information about the current client(s). The Interface “IVisualizationClient” contains a UserName property.

Thank you! What about the specific/ current user(s) actions, how are these retrieved?

Here’s an example from CODESYS Forge that records changes in variable values triggered by user input within the visualization.
