SCADA (PART 1)
Basic SCADA
Only use RTU/PLC
Only 1 MTU is used
Room temperature control and water level control
car manufacturing robots
Intergrated SCADA
Only consists of several PLC/RTUs to several DCSs using only 1 MTU
MTU is connected to the computer using LAN, WAN and internet
Examples are water systems, subway systems and security systems
Networked SCADA
More than 1 MTU connected to each other and 1 MTU will act as a coordinator
MTU center connects with the outside using LAN, WAN and the Internet.
Examples are Power Systems and Communication Systems.
Introduction
system that monitors and controls field devices
Scada can also help maintain efficiency by collecting and processing data
Modern SCADA uses a computer to show the status of sensors and actuators
Typical SCADA system consists of an RTU connected to a process transmitter and a final control element, performing basic control functions
These RTU devices communicate digitally to the MTU at a central location
RTU stands for Remote Terminal Unit
SCADA communication architecture is based on Master terminology
Supervisory control and data acquisition.
Known as Remote Telemetry Unit or Remote Telecontrol Unit.
A RTU is a microprocessor based device that monitors and controls field devices
SCADA is divided into 3
Networked SCADA
Basic SCADA
Integrated SCADA
SCADA is divided into 5 encompasses
displaying information
carrying out
collecting
transferring
control and manipulate
Minimum instruments monitored by SCADA are
alarm
lamps
analog meter
5 SCADA elements
Operator
Human Machine Interface (HMI)
Master Terminal Unit (MTU)
Remote Terminal Unit (RTU)
