AutomationAutomationAutomation is basically a delegation of human control function to controltechnical equipment.Automation is the use of control systems and information technologiesreducing the need for human intervention.
It is a technology dealing with theapplication of• mechatronics• computersfor production of goods and services.Automation is broadly classified into• manufacturing automation• service automation3

Automation ToolsAutomation ToolsDifferent types of automation tools exist:DCS - Distributed Control SystemHMI - Human Machine InterfaceSCADA - Supervisory Control and Data AcquisitionPLC - Programmable Logic ControllerInstrumentationMotion control
SCADA stands for supervisory control and dataacquisition.It generally refers to an industrial controlsystem: a computer system monitoring andcontrolling a process.The process can be industrial, infrastructure orfacility-based.Supervisory Control and Data Acquisition System refersto a system that enables an electric utility to monitor,coordinate, control and operate distribution componentsand devices in a real-time mode from remote locationswith acquisition of data for analysis and planning, fromone central location

IMPACT of AUTOMATIONIMPACT of AUTOMATIONAutomation has had a notable impact in a wide range of highlyvisible industries beyond manufacturing.Once-ubiquitous telephone operators have been replaced largely byautomated telephone switchboards and answering machines.Medical processes such as primary screening inelectrocardiography or radiography and laboratory analysis ofhuman genes, cells, and tissues are carried out at much greaterspeed and accuracy by automated systems.In general, automation has been responsible for the shift in the worldeconomy from agrarian to industrial in the 19th century and fromindustrial to services in the 20th century.
ADVANTAGESADVANTAGESAccurate and consistentinformationFaster fault identificationImproved availability of system Increased Production
ADVANTAGESADVANTAGESReduced Cost Maintenance of Quality & QuantityImproved Safety Conditions
DisadvantagesDisadvantagesThe main disadvantages of automation are:Technology limits: Current technology is unable toautomate all the desired tasks.Unpredictable development costs.:The research anddevelopment cost of automating a process is difficultto predict accurately beforehand. Since this cost canhave a large impact on profitability, its possible tofinish automating a process only to discover thattheres no economic advantage in doing so.Initial costs are relatively high: The automation of anew product required a huge initial investment incomparison with the unit cost of the product,although the cost of automation is spread in manyproduct batches
