zoom level operator can view 3 minutes of trend data and Zoom In button will be inactive. At minimum zoom level operator can view full 120 hours of trend data and Zoom Out button will be inactive.

Back/Forward:

•These buttons allow the operator to move the plot and view trend data at different time intervals.

•Forward button will be inactive when the operator is viewing the first data point plotted on the screen (i.e. when time interval is displaying 0:00). Back but- ton will be inactive when the operator is viewing the last data point on the screen (i.e. when time interval is displaying 120:00). At minimum zoom level, Back & Forward buttons will be inactive.

Trace:

•This button allows the operator to move a white cur- sor line across all four trend lines and receive a read- out of all four variables at that point in time. When the Trace button is pressed, cursor position is displayed along with value of all four variables on the screen.

Hold:

•This button allows the operator to stop the data from advancing on the display without stopping the trend feature. When the Hold button in pressed, Hold Time is displayed on the screen.

Trace Back( < ) / Forward ( > ):

•These buttons allow the operator to move a white cursor line across trend lines and view trend data value at that point. These buttons will only be active when Trace button is pressed. When these buttons are pressed, cursor is moved and trace position is up- dated on the screen.

Setup:

•This button allows operator to open the Trend Setup screen. This button is inactive when the trend feature is running.

Trend Data Storage

The trend analysis screen shows recorded data for prob- lem analysis or tuning improvements. A logging buffer holds 5 minutes of data sampled at 10 second intervals.

When the logging buffer fills with 5 minutes of data, it is automatically transferred to a temp csv file. A temp trend file will hold up to 1MB of accumulated data. When the temp file has accumulated 1MB of data, data from temp file is written to new trend file and temp file is overwritten with new data in logging buffer till next 1MB of data. When a total of 15MB of trend data is accu- mulated, and the logging buffer has filled with another 5 minutes of data to write, the file with the oldest trend data is deleted.
