PLC programming is the act of creating internal logic for a programmable logic controller (PLC). PLCs are typically programmed in a “language” proprietary to the controller; accurately described as a translation from spoken word (“If condition 1 is true and condition 3 is false, turn on output 12”) to something the controller can interpret and execute (“If I1.0 = 1 and I1.2 = 0 then

They are one of the most advanced and simplest forms of control systems which are now replacing hard wired logic relays at a large scale. A programmable logic controller (PLC) is a small, modular solid state computer with customized instructions for performing a particular task. PLCs, which are used in industrial control systems for a wide variety of industries, have largely replaced mechanical relays, drum sequencers and cam timers.

How does a PLC work? PLC takes microprocessor as the core and has many characteristics of microcomputer, but its working method is very different from microcomputer. Microcomputers generally work in a waiting mode. The PLC works by centralized input, centralized output and periodic cyclic scanning. The time used for each cyclic scan is called a scan cycle. PLC Latching Function PLC Tutorials There are often situations where it is necessary to hold an output energized, even when the input ceases.

The PLC usually also have some memory called ROM and EEPROM.

Quick, clear and error-free. Using traditional terminal blocks, connecting controllers to field devices becomes extremely time-consuming. System cabling from The IA 130 can be used to perform basic exercises on a PLC (programmable logic controller). A PLC is essentially a computer adapted to the needs of industry .
