The acquired information from remote modules is processed by the front end processor and retransmitted to every node in the network.

The SCADAPAC XAR 2-D system works with two paralell servers, guarrantying the system’s redundancy.
Also it has a information terminal for engineering exploitation, system management, statistics etc.

The man-machine interface (MMI) is programmed using a OSF MOTIF with windows environment.

Additionally to traditional SCADA functions, SCADAPAC XAR 2-D can perform the following:

ELECTRICAL NETWORK AUTOMATION

GIS SYSTEM CONNECTION
PLC FUNCTIONS
ENGINEERING TERMINAL
MANAGEMENT SERVER
SAPR3 SYSTEM CONNECTION
INTELLIGENT PHONE COMMUTER
REMOTE DIAGNOSTICS VIA PHONE LINE
REMOTE DIAGNOSTICS VIA INTRA OR INTERNET.
MAINTENANCE MODULES
MONITOR AND CONTROL OF SUBSTATION AUTOMATION SYSTEMS
WAN CONNECTION

GENERAL DESCRIPTION.
The SCADAPAC XAR 2D is part of a series of automation products developed by Eseam, Inc. based on open architectures for software and hardware platforms.
Our core technology is based on HP computer equipment and Motorola Computer Group’s embedded boards for the different kinds of front end processors.

HARDWARE ARCHITECTURE

The SCADAPAC XAR 2D supervisory control system is comprised of two servers, a front end processor, two printers (events and reports) and can support up to 32 communication channels.

Communications run through a LAN Ethernet, keyboard, printers and UPS.

SOFTWARE ARCHITECTURE

The programming structure of the software is divided into three great blocks.

Each of these blocks represent the application and function level of each software module that comprise the entire MMI.

The core of each of this layers is UNIX or Windows according to user´s requirement.

The system’s phylosophy comprises different programming modules that act independently and perform their links to the rest of the system through a relational data base and the different routines on the operative system.

THE THREE BLOCKS ARE:

The first block of the sytem constitutes the basic programming modules, fundamental for the system’s operation.

data base
SCADA program
communication module
diagram editor
function and report management
system monitoring
The second block comprises the manmachine interface configuration.
diagram creation
report creation
panel creation
screen personalization
function personalization
logger management
trend and statistics management

The third and last block of the system, is comprised by the applications that personalize and are specific to the system involved, they could be:

distribution
transmission
generation

Some examples of specific application modules are:

automatic generation control
overload drain
distribution network automation
ied setting changes
economic dispatch
load flow
voltage flow conrtrol
postmortem analysis
ied oscillography
downtime management
submaster module
maintenance modules
configuration and control of intelligent phone line commutter

MAN MACHINE INTERFACE
Using different software modules, an information explotation structure was created. It defines the profile of the different MMI users:

maintenance personnel
control personnel
substation personnel
communications personnel
operators

The block diagram looks like this:
These different operation modes, gather all required functions for the optimum exploitation of the system’s information. Starting with the basic SCADA and protection functions up to IED settings changes and oscillography downloads done from any terminal.

Every module has a security level access and will require a password to enter.
