Is it true that Historian controls the recording of Process data and Alarm data from the System Platform?

The assertion that the Historian controls the recording of Process data and Alarm data from the System Platform is true because the Historian is specifically designed to collect, store, and manage time-series data that is generated by various processes and alarms. It serves as a centralized repository for this data, allowing for effective analysis, reporting, and monitoring of the operational state of the system.

The Historian integrates seamlessly with the System Platform to ensure that both process-related data and alarm events are efficiently captured. This includes not just logging when alarms occur but also recording the context surrounding these events, which is vital for troubleshooting and improving system performance. This capability to manage both types of data reinforces the Historian's role in industrial data management and enhances operational visibility.

In contrast to this choice, options suggesting that the Historian only monitors data or that it does not track alarm data overlook its comprehensive functionality. The ability to log data from internal and external sources illustrates the flexibility and importance of the Historian in industrial automation settings.
