LiveView Thresholds

Thresholds let you display tag readings that fall outside of the normal range. You can apply it to an individual cell or a range of cells. You determine the tag or tags for which you want to display out-of-normal (threshold) readings. When the value of the tag in a cell (or any tag in a cell range) is below the minimum or above the maximum that you set, the tag value displays in the threshold cell.

You can set both minimum and maximum values for a cell or cell range. Use different colors to indicate the high and low readings.

To add a threshold:

  1. In LiveView Setup, click the Threshold sub-tab.
  2. Depending on the number of cells, do one of the following:
    • Cell: For a single cell: Select the cell for which you want the font color to change. The font color will change when the value for the tag in that cell goes above the specified Max Value (or below the Min Value) for the threshold.
    • Cell Range: For a range of cells, either select the range, or type the range in the format C4:C20.

    3. When setting up a multiple-device table, you should use a cell range to ensure that threshold font colors display for each device in the table.

  3. In Min Value, type the low value for the "normal" range. If the tag value drops below this value, the cell font color will change as specified in step 4.
  4. Below Min Threshold Color: Open the color palette and select the font color that you want to indicate the "low" status.
  5. In Max Value, type the high value for the "normal" range. If the tag value goes above this value, the cell font color will change as specified in step 6.
  6. Above Max Threshold Color: Open the color palette and select the font color that you want to indicate the "high" status.
  7. Insert Location: Choose an empty cell, one that is not part of the table. This cell will be the location for the threshold definition that you are creating.

    8. The default cell for the threshold definition is the next available cell in the template. For example, if the tag in cell B7 has an unused cell to the right of it (C7), the threshold definition defaults to C7. Then, when the value in B7 exceeds the threshold defined in C7, the value in B7 displays in the font color you specified. To override the default cell location, change it in the Insert Location field.

  8. Click Insert to create the thresholds.

The threshold definition is in the form: <<Threshold;B2:B20;Min=100;Max=1000>>
