A programmable logic controller, PLC, or programmable controller is a digital computer usedfor automation of typically industrial electromechanical processes, such as control of machinery onfactory assembly lines, amusement rides, or light fixtures. PLCs are used in many machines, in manyindustries. PLCs are designed for multiple arrangements of digital and analog inputs and outputs,extended temperature ranges, immunity to electrical noise, and resistance to vibration and impact.Programs to control machine operation are typically stored in battery-backed-up or non-volatilememory. A PLC is an example of a "hard" real-time system since output results must be produced inresponse to input conditions within a limited time, otherwise unintended operation will result. Content :-

Early PLCs were designed to replace relay logic systems. These PLCs were programmed in"ladder logic", which strongly resembles a schematic diagram of relay logic. This program notationwas chosen to reduce training demands for the existing technicians. Other early PLCs used a form ofinstruction list programming, based on a stack-based logic solver.

Programming

Early PLCs, up to the mid-1990s, were programmed using proprietary programming panels or special-purpose programming terminals, which often had dedicated function keys representing the variouslogical elements of PLC programs.[2] Some proprietary programming terminals displayed the elementsof PLC programs as graphic symbols, but plain ASCII character representations of contacts, coils, andwires were common. Programs were stored on cassette tape cartridges. Facilities for printing anddocumentation were minimal due to lack of memory capacity. The oldest PLCs used non-volatilemagnetic core memory.Our students Aware about the Which troubleshoot use for industry usingAutomation
