MDT Chamber Temperature History and Trend Plots

This panel provides access to historical data for the MDT temperature sensors. This can not be done via the common PVSS Trending widget normally used in DCS since MDT temeperature data is written to Oracle user tables instead of PVSS Oracle archives. The data retrieved is displayed as a value over time trend plot.

Instructions for Usage. Interactive Control and Buttons.

To display the temperature data of a chamber for a given time period,

• Select the start and end of the period in Start Time and Stop Time.
• Select the chamber you want to view from the displayed list, by clicking on it. You can specify a filter in the field Filter to restrict the list of chambers offered.
• Press Retrieve Data.

In the trend plot, you can zoom by selecting a range by dragging the mouse while pressing the left mouse button.
