A central host computer server or servers (sometimes called a SCADA
master) located at the control center
Remote Terminal Units, or RTUs, converting sensor signals to digital
data and sending digital data to the supervisory system control center
A communications system used to transfer data between RTUs and
the central supervisory system. The system can be radio, telephone,
cable, satellite, etc., or any combination of these
The customer is a provider of satellite-based SCADA systems for power
distributioncompanies.
The customer has developed a next-generation satellite communication
system, using newer and faster components; to monitor and manage
remote units. The main components of the system are the HUB, situated in
the Control Center, and USATs (Ultra Small Aperture Terminals) installed in
remote locations. The earlier generation of USATs used TI's multicore
processor TMS320C82; this was replaced with TMS320C6414 in the new
USATs. The customer's requirement was for Mistral to port the software to
runontheC64xxplatform.
ThefirstandsecondgenerationoftheSCADAHUBsconsistedofaPCwhich
had a GUI application running on it. The PC interfaced with the Transmitter,
Receiver and Demodulator boards, housed in a VME chassis. The interface
between the embedded PC and the receiver board was SCSI. The SCADA
masterscommunicatewiththeHUBoverSerialLAN
The first generation SCADA HUB supported only the CDC protocol, and
transmitted data at the rate of 0.6 kbps. The inbound data rates could be
either0.6kbpsor1.2kbps.
InthesecondgenerationHUB,out-bounddataratesof0.6kbpsand9.6kbps
were supported. The in-bound data rates could be 0.6, 1.2, 2.4, 4.8 or 9.6
kbps.ThesecondgenerationHUBsupportedvariousprotocols;viz.0.6CDC,
9.6CDC,FCDC,DNPandOLM.
Introduction
Supervisory systems have revolutionized the industrial automation
scenario all over the world. Almost all critical industrial infrastructure
and processes are managed remotely from central control rooms,
using computers and communications networks. One such industrial
controlsystemisSCADA;anacronymforSupervisoryControlandData
Acquisition. The flow of gas and oil through pipes, management of a
powergrid,processinganddistributionofwater,operationofchemical
plants, and the signaling network for railways, all use various forms of
SCADAtechnology.
This case study highlights Mistral's expertise in designing the
software for a satellite-based SCADA system used for the control and
monitoringofsub-stationsandpower-grids.
