on the screen exactly as they were at the time that the event occurred. This includes numeric elements with changing numeric values, graphical elements that change their form, or even ALC lines with varying colors. B E T TE R A N A LYS E S FO R H I G H E R Q UA LIT Y The Process Recorder is not an expansion of the existing tools; it archives processes in a way that an alarm list or an events list never could. You can save the details of erroneous and successful processes, as well as create animated or 3D versions of the processes in the process screen. This makes analysis much easier and quicker compared to regular list searches. Even with well-documented production processes, there may be quality defects to investigate. With the Process Recorder, you can determine exactly when the problem arises, allowing you to fi nd the precise time at which the anomalous data was produced. You can also discover which areas or which customers in a power network were affected by a power failure. It is also easier to retrace misconfigurations – for example, issues arising from faulty alarm triggers. I D E A L FO R P RO C E S S - O R I E NTE D I N D U S TR I E S The Process Recorder offers new and improved approaches to error diagnostics and process analysis, and thus enhances the quality assurance of the processes controlled
by zenon. The system is not only key to improving energy management; benefits extend to industries such as food and drink production, automotive, transportation, the chemical and pharmaceutical industry which stand to gain significantly from what the system offers.
