Programmable Logic Controller (PLC) is a modular, scalable rack-based industrial controller delivering powerful performance in a control application. It is applied in various processing applications in industries such as oil and gas, steel, cement, power, food and beverage and delivers a blend of power, performance and efficiency.

PLC is a pocket-sized industrial logic controller powered by a high-speed processor. It can operate in a standalone manner, in a peer-to-peer environment, or in a SCADA topology with Experion HS. It features a wide range of components (the CPU, power supplies, discrete and analog, I/O modules, network modules, and racks) which are available in different modules to suit many different applications.

PLC takes information from various sensors and uses it to control different machines. A reliable processor makes it intrinsically powerful, and all program instructions are executed at a high speed of 42 ns/step. A dedicated Ethernet-based I/O bus controller supplements the main processor in I/O refresh to achieve high speed scanning, and its redundancy feature ensure high availability, especially for critical applications. Available with standard functions, it also supports creation of new or user-defined functions. It works in a loop-based, user-defined program where it waits for input and output at predefined intervals, and can perform self-diagnostics for system errors and trouble shooting. Built on open network standards, this programmable logic controller is integrated with the Experion platform.
