The EventRecorder Viewer is a standalone tool that can be installed on any Windows computer. It is available as part of the Control plus bundle under Common/EventViewer.
Usually, this tool allows to open a database file created by the EventRecorder service on the target system (either directly: *.sdf or exported through the app: *.oer) The sdf file can be downloaded from the target system by connecting to the OpconData$ network share.
It is also possible to connect the Viewer directly to the EventRecorder service on the target system if the network allows this. In this case you get live updates just like in the HMI on the target system. The Viewer is always connected to localhost by default, but the menu in the bottom right allows you to disconnect from localhost. Afterwards, you can provide the IP address or hostname of the computer running the EventRecorder service and connect to it.
