4.7.3 Channel Screen
The Channel screen shown below displays a 24 hour trend of input data for the channel selected. Vertical
tic marks are each hour and horizontal tic marks are each 10% of full scale. Colored lines indicate alarm
levels. Since each data point must be collected for several minutes before it may be displayed, it is likely
input values will fluctuate during this interval. Therefore, MAX, MIN and AVERAGE values are stored in
the controller for each subinterval. Checking the Min, Max and Avg box in the lower left corner turns the
respective lines on and off. If there is no trend data available, the corresponding section of the graph will
be grayed out. This will occur on power interruptions.
The top portion of each trend screen indicates channel number, real time reading in engineering units,
and measurement name. When a channel reaches alarm state, the colored bar changes to the color that
represents that alarm level and flashes. Once the alarm is acknowledged the bar stops flashing.
The top portion of the page updates automatically every 15 seconds. The trend is updated when a channel
is changed or the ‘Refresh Trend’ button is pressed.
