Accessing and Using SCADA Features
SCADA information can be accessed in NMS in several different ways and for different purposes.
SCADA operations that result in customers out appear as real outage events on the trouble related views of the Work Agenda in the same manner as outages that were generated by call information except that they are automatically confirmed and appear immediately as real outages. These operations are also included on the Asset Operations List on the Work Agenda.
The SCADA Summary provides the current values and qualities of all mapped SCADA measurements in NMS, including both analog and digital measurements. You can filter, sort, modify, and comment on the measurements in the SCADA Summary.
The Viewer displays dynamically updated SCADA information at or near the corresponding asset on the distribution network map. The data may be displayed via text annotation or, in the case of status and digital values, symbol changes. SCADA information that may be displayed on the Viewer includes valve status and other status values, digital values, and analog values, all with quality codes.
The Viewer also shows all SCADA analog and digital values in the balloon dialog box.
The Alarms list is an extension of the Work Agenda window and may display various alarm messages that are sent from the SCADA system.
Any SCADA status values that result in a valve being in its off-nominal state will cause the asset to appear in the Abnormal Asset Summary.
Systems with a two-way interface let you perform remote operations (for example, open/close and tagging) on SCADA asset through an enhanced version of the Control Tool.
