Hi  
Is there something equivalent to PI event frames in Ignition? I want to use ignition mainly as a historian to capture time series data over OPC and charting it. But also wan to be able to contextulize the data, for ex startup and shutdown of a specific batch, downtime etc. Is this possible with ignition?

Thanks for the feedback in advance
