About This Document

This document is supplied as a part of Alstom Grid’s eterrapipeline product.

Purpose of This Document

The purpose of this guide is to provide basic instructions for the user tasks of Supervisory Control and Data Acquisition (SCADA). This guide describes procedures for SCADA and related applications.

Who Should Use This Document

This guide is intended for all SCADA users.

Structure of This Document

This document is structured in the following manner:

Chapter 1 provides a brief overview of the SCADA application.

Chapter 2 explains basic SCADA procedures, such as how to override scanned values, and how to set parameters that determine how the application operates (e.g., setting the limits enforced on analog values).

Chapter 3 explains user-defined calculation procedures. Userdefined calculations (USERCALC) enable you to define calculations based on inputs from SCADA involving arithmetic, and logical and comparative functions, as well as conditional branching. Calculated results can replace values from real-time data points when the latter are defined to derive data from an external source or are out-of-scan.

Chapter 4 explains historical data recording procedures. Historical data recording (HDR) records and stores data from selected SCADA status, analog, or accumulator points in historical files. Data from these files can later be retrieved to reconstruct the SCADAMOM database as it existed at a particular time in the past, or display measurements for selected SCADA values over a specified period of time.

Chapter 5 explains tagging procedures. Tagging provides a mechanism for annotating certain SCADA records (using tags). Tags can be used to alter processing for a record (such as blocking supervisory controls), or they can be strictly informational.

Chapter 6 lists the SCADA displays that are accessed using eterrabrowser. For each display, the various user tasks that can be performed from the display are listed.
