A Programmable Logic Controller Is More Or Less a little Computer with a Built-in Operating System (OS). This OS Is Highly dedicated To Handle Incoming Events in Real Time, I.e. at the Time of Their Occurrence.
A PLC is principally used to Control Machinery, Programs Written for PLCs Consist In easy Terms on Instructions to turn on and off Outputs Based on Input Conditions and the Internal Program.
The PLC Has Input Lines Where Sensors Are Connected To Notify Upon Events (e.g. Temperature Above/below A Certain Level, Liquid Level Reached, Etc.), And Output Lines To Signal Any Reaction To The Incoming Events (e.g. Start An Engine, Open/close A Valve, Etc.).
The System Monitors Whether Certain Alarm Conditions Are Satisfied, To Determine When An Alarm Event Has Occurred. Once An Alarm Event Has Been Detected, One Or More Actions Are Taken. Activation Of One Or More Alarm Indicators, And Perhaps The Generation Of Email Or Text Messages So That Management Or Remote SCADA Operators Are Informed.
