Configure Specification properties

ThresholdSource

The method used to derive the threshold values for this field. This property appears only when the data type is Numeric or Boolean.

Options:

• None: Specifies that no threshold is applied to this field.

• Field: When you specify Field, a threshold range item appears directly beneath this field where you can specify the upper and lower limits of the threshold.

• Product: You can use a product specification to define the limits of the threshold.

If the DataType is Boolean, and Threshold value is Field, a Threshold Value appears.

AVEVA Production Management adds a threshold value definition to a Boolean field automatically if you change the field property ThresholdSource value to Field. A field with data type of Boolean can have one threshold value item only.

For the threshold value item to be available for the field, specify the following values on the field.

If the DataType is Numeric, and Threshold value is Field, a Threshold Range appears.

AVEVA Production Management adds a threshold range definition to a Numeric field automatically if you change the ThresholdSource property on the field to Field. You can also add extra threshold ranges.

For the threshold range item to be available for the field, specify the following values on the field.

Note: If you change any of the field property values so that they no longer meet the requirements to add threshold ranges, any existing threshold range child items may disappear.
