Alarm Limits

Use the fields within the Alarm Limits section of the Counter Point tab to specify the properties that are associated with a SCADAPack x70 Counter point's limits.

The counter point inherits its Enabled setting and High Limit from the SCADAPack x70 Counter Configuration item with which it is associated (see Configure the Event Attributes). (If you have not re-opened this configuration Form since using the Form's SCADAPack x70 Object field to associate this Point with the relevant Configuration item, you may need to refresh the Form in order for this field to display its inherited value. Likewise, if the inherited value is changed on that Configuration item's Form while this Point Form remains open, you might also need to refresh this Form to display the updated inherited value. To do this, save the configuration changes.) The Enabled check box indicates whether the Alarm Limit is enabled on the associated Configuration item. A counter point has only one Alarm Limit. If the Alarm Limit is not enabled on the Configuration item, the associated fields are grayed out. The Alarm Limit is only enabled when the associated RTU Event on the Configuration item is set to an option other than 'Disabled' (see Configure the Event Attributes). Geo SCADA Expert applies the defined Multiplier to the Limit value from the Configuration item and then displays the resulting value in the Limits column on the counter point's Counter Point tab (see Configure the Multiplier Value). The value of the High Limit field is scaled into the engineering units.

The other Alarm Limit fields are common to various types of counter point. For more information, see Configure the Limits for a Counter-Type Point in the Geo SCADA Expert Guide to Core Point Configuration.

For information about the properties that appear towards the bottom of the Alarm Limits section, see the following sections:

• Tune Limits—see Define Whether a Counter-Type Point’s Limits can be Tuned in the Geo SCADA Expert Guide to Core Point Configuration.
• Area of Interest—This field is only displayed if the Area of Interest feature is enabled on your system. Use the field to specify the Area of Interest with which any state-related point alarms or events are to be associated (see Specify the Area of Interest Associated with a Point’s State-Related Alarms and Events).
