Use the fields within the Alarm Limits section of the Analog Point tab to set limits for the IEC 61850 analog point and specify whether an alarm or event is generated if the point’s value exceeds those limits.
Many of the Alarm Limit fields are common to various types of analog points on different drivers (see Configure the Limits for an Analog Point in the Geo SCADA Expert Guide to Core Point Configuration). In addition to the usual Limits, IEC 61850 analog points also have an Invalid state. Use the fields associated with this state to define the settings that are to apply if the analog to digital conversion process fails in the IED.
For information on the properties that appear toward the bottom of the Alarm Limits section, see the following sections:
- Hysteresis—see Specify the Hysteresis - the Minimum Value Change that can Clear an Alarm in the Geo SCADA Expert Guide to Core Point Configuration.
- Engineering Units Exceeded—see Define how Over Range and Under Range Values are Processed in the Geo SCADA Expert Guide to Core Point Configuration.
- Tune Limits—see Define whether an Analog Point’s Limits can be Tuned in the Geo SCADA Expert Guide to Core Point Configuration.
