3. INTRODUCTION TO PACiS
Schneider Electric philosophy is to provide a full range of products, computers, gateways
and IEDs products. Each of these products can be used independently, or can be integrated
to form a PACiS system: a Digital Control System (DCS) SCADA system.
3.1 What are PACiS Products?
Driven by worldwide requirements for advanced applications in SCADA, Digital Control
Systems, Automation, control and monitoring, Schneider Electric have designed and
developed a new and comprehensive system: PACiS, specifically intended for the power
process environment and electrical utility industry. It allows building of a customised solution
for Control, Monitoring, Measurement and Automation of electrical processes.
This new generation of products has been specially tailored for the PACiS system. A major
objective for PACiS products is to make this range as easy as possible for the customer to
accept, adapt and integrate into their system and operation.
One of the key features is that this product family is based on a IEC61850 client/server
architecture.
3.2 Application and Scope
The Telecontrol Gateway (GTW) is the PACiS control system's gateway. It provides the
system with a connection to a Remote Control Point (RCP), located in a dispatching centre
(SCADA), thus allowing the dispatcher to perform remote control and monitoring of the
system from the SCADA.
Main functions of the gateway are:
•
Transmission of remote indications from the system to the control centre.
•
Transmission of remote measurements from the system to the control centre.
•
Transmission of commands to the system, issued from the remote control centre.
GTW and RCP communicate together by data exchanges based on a specific
communication protocol. The TGW label describes in fact a range of bridges, each
supporting a protocol dedicated to a specific remote control type.
The communication with the SCADA uses a RS232 or Ethernet links.
The TG may be redundant in the PACiS system in order to ensure the quality of service in
case of a communication failure. Moreover, it should be multi-protocol, this means it has to
manage several different protocols in order to communicate with several different SCADAs.
A standardised protocol is used in accordance with the choice of each project's SCADA
supplier.
