The following fields are displayed toward the bottom of the Alarm Limits section on the Analog Point tab:
- Zero Threshold—Use to specify the engineering value below which the DNP3 SCADAPack analog point’s value will be forced to zero.
This property does not apply to Analog Output points that have a Point Type of Physical Out.
- Engineering Units Exceeded—Use to specify how ClearSCADA processes the point’s value if the value returned from the SCADAPack E outstation is greater than Overrange or less the Underrange. For further information, see Define how Over Range and Under Range Values are Processed in the ClearSCADA Guide to Core Point Configuration.
