Turn AF Event Frames into a readable timeline inside PI Vision. Point the symbol at an Asset Framework database and every event frame in the display time range appears as a bar, grouped into lanes by asset, template or severity. Hover for a tooltip, click for attributes, annotations and comments - and acknowledge, edit or annotate without leaving the chart, because writes go back to AF. One toolbar button ranks every cause in view by total duration, so the downtime Pareto that usually takes a spreadsheet is one click. No event frames yet? Drop ordinary digital or analog tags and each tag becomes a lane, with every state change drawn as a bar.
