When I was working in Saudi Arabia as a control valve technician I used to work with SCAD in the factory.
It is very good to monitor all the loops or fields from big screen. Also, you can control them for example you can turn the control valve on or off. In addition, you can read the temperature, pressure, flow and check whatever you want like the oil in the thank. it is amazing system and helpful for plants.

SCADA (supervisory
control and data acquisition) is a type of industrial
control system (ICS). Industrial control systems are computer controlled systems that
monitor and control industrial processes that exist in the physical world.
SCADA systems historically distinguish themselves from other ICS systems by
being large scale processes that can include multiple sites, and large
distances. These processes include industrial, infrastructure, and
facility-based processes, as described below:
·
Industrial
processes include those of manufacturing, production, power generation, fabrication,
and refining, and may run in continuous, batch, repetitive, or discrete modes.
·
Infrastructure processes
may be public or private, and include water treatment and distribution,
wastewater collection and treatment, oil and gas
pipelines, electrical
power transmission and distribution, wind farms, civil defense
siren systems, and large communication systems.
·
Facility processes occur both in public facilities and private ones,
including buildings, airports, ships, and space stations. They monitor and
control heating, ventilation, and air conditioning systems
(HVAC), access,
and energy
consumption.
·
A human–machine
interface or HMI is the apparatus or device which presents
process data to a human operator, and through this, the human operator monitors
and controls the process.
·
SCADA is used as a safety tool as in lock-out tag-out
·
A supervisory (computer) system, gathering (acquiring) data on the
process and sending commands (control) to the process.
·
Remote terminal
units (RTUs) connecting to sensors in the process, converting sensor signals to digital data and
sending digital data to the supervisory system.
·
Programmable
logic controller (PLCs) used as field devices because they are
more economical, versatile, flexible, and configurable than special-purpose
RTUs.
·
Communication infrastructure connecting the supervisory system to the
remote terminal units.
·
Various process and analytical instrumentation
A SCADA system usually consists of the following subsystems:
·
A human–machine interface or HMI is the apparatus or device which presents
process data to a human operator, and through this, the human operator monitors
and controls the process.
·
A supervisory (computer) system, gathering (acquiring) data on the
process and sending commands (control) to the process.
