What is the typical architecture of scada?

Question

Accepted Answer

SCADA typically consists of a hierarchical architecture with multiple levels of control and monitoring.

SCADA systems have a distributed architecture with multiple remote terminal units (RTUs) or programmable logic controllers (PLCs) connected to a central control system.
The central control system is responsible for collecting data from the RTUs/PLCs and displaying it to the operator.
SCADA systems may also include a supervisory computer, which provides a higher level of control and monitoring.
The architecture may also include a data historian, which stores historical data for analysis and reporting.
SCADA systems may use various communication protocols such as Modbus, DNP3, and OPC to communicate with the RTUs/PLCs.
Examples of industries that use SCADA systems include power generation, water treatment, and oil and gas.

Accepted Answer

SCADA systems automate the extraction, monitoring, processing, distribution, recording, and display of data gathered from remote field devices like sensors, factory machines, motors, pumps, valves, and other end devices in asset-heavy environments like industrial enterprises, manufacturing facilities, nuclear power plants, and oil refineries.

Accepted Answer

Generally the SCADA system includes the following components: local processors, operating equipment, PLCs, instruments, remote terminal unit, intelligent electronic device, master terminal unit or host computers and a PC with human machine interface.

Accepted Answer

The SCADA system utilizes a WAN and LAN networks, the WAN and LAN consist of internet protocols used for communication between the master station and devices. The physical equipment like sensors connected to the PLCs or RTUs. The RTUs convert the sensor signals to digital data and sends digital data to the master
