Use the PVTable application (File → PVTable) for live timestamped PV monitoring. For a custom rolling buffer like WinCC OnlineTableControl, use a TableWidget with a Python script that appends [timestamp, pv1_value, pv2_value] rows to the widget value property. See /app/pvtable/ for PVTable implementation and script docs at control-system-studio.readthedocs.io/en/latest/app/display/editor/doc/scripts.html
