Industrial Control Systems (ICS) are the backbone of manufacturing, utilities, and infrastructure. They are used to monitor and control the physical processes that make up these systems. Although the functionality of ICS varies from industry to industry, they all share a common goal: to increase efficiency and productivity while minimising risk.
History of ICS
The history of Industrial Control System is a bit like the story of the internet. It starts small, with a few people who know what they’re doing, and then it explodes as more companies begin to use it.
ICS was first developed in the 1950s by engineers from General Electric and Westinghouse Electric Corporation. These engineers were looking for ways to control electric utilities remotely so that they could avoid sending their employees into dangerous situations when inspecting or repairing power lines and switches.
The result was called Distributed Control System (DCS), which allowed electrical power plants across America to be managed by one central computer system located in each facility.
DCS had many advantages over previous systems that relied on mechanical controls: it was safer because workers didn’t need direct access to dangerous equipment; there were fewer errors because every step in operation could be programmed into DCS.
There was increased efficiency because work could be done faster than ever before; and finally, there were lower costs associated with upkeep since less manual labour was required at each plant site.
Over time, DCS spread throughout other industries where ICS is used today: oil and gas refineries, chemical processing facilities; water treatment plants; nuclear reactors; manufacturing plants serving heavy industries such as mining operations or construction projects (such as building dams).
IC systems defined
Your Industrial Control System (ICS) is a system of hardware and software, operating in real time, to control the process. It may be used to control a process, monitor and control a process, or monitor and control a network.
Supervisory Control and Data Acquisition, or SCADA systems, are a collection of hardware and software that monitors and controls an industrial process.
SCADA systems are used in many industries to regulate processes like manufacturing, oil refining, power transmission and distribution and water treatment plants.
SCADA systems typically feature a master controller that acts as the operating system for managing all network components.
The controller receives information from input devices such as sensors or switches located throughout the facility it’s monitoring; then it relays commands via serial connections to actuators—typically automated valves or pumps—that perform physical work on equipment at remote locations within the plant.
A DCS system is a computer-based system that controls a process. It consists of hardware, software and the operator interface that allows users to monitor and control the operation of their processes.
There is a database that stores information on all aspects of the process from raw materials to final products.
It has network connections for communicating with other DCS systems or ICS devices such as PLCs (Programmable Logic Controllers).
Industrial Control Systems (ICS) are computer systems that are used to control industrial processes. They are usually found in manufacturing plants, power plants and other facilities where large amounts of equipment need to be monitored and controlled.
ICs have been designed with a high level of security so as not to allow unauthorised access or tampering with the processes being controlled. This makes them an attractive target for hackers who want access to the critical systems that these controllers are running.
ICS is a concept that has been around for many years and has helped to revolutionise the world of manufacturing.
ICS systems have enabled businesses to optimise their operations and increase efficiency levels. However, there are still some security concerns with these types of systems which can be mitigated by following best practices when designing an ICS network.
