Alarm Limits

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

The analog point inherits its Limit values from the SCADAPack x70 Analog Configuration item with which it is associated (see Configure the SCADAPack x70 Device's Alarm Limits Settings, and see Configure the Out Of Range Limits). (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 these fields to display their inherited values. Likewise, if the inherited values are 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 values. To do this, save the configuration changes.) The Limits are specified in engineering (floating point) values. If need be, you can see how these values correspond to the point's raw values by scrolling to the SCADAPack Scaling section of this tab. Again, these values are inherited from the SCADAPack x70 Analog Configuration item with which the analog point is associated (see Specify the SCADAPack x70 Device's Point Scaling).

The other Alarm Limit fields are common to various types of analog point. For more information, see Configure the Limits for an Analog 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, select the relevant links below:

• Engineering Units Exceeded—Use this check box to specify how Geo SCADA Expert processes the analog point's value when that value is overrange or underrange (see Define how Over Range and Under Range Values are Processed).
• Out of Range Check—Use to Specify how the Driver Determines whether a Reported Value is Out of Range.
• Tune Limits—Use to Define whether an Analog Point’s Limits can be Tuned.
• 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).
