| Popis: | The programmable Logic Controller (PLC) is the central controlling unit in the industry or a process. The effective operation of the process and safety considerations if programmed appropriately can meet the required objectives. The present technical paper briefly distinguishes the present automation systems and the past technologies to identify and explore the capabilities of PLCs for any process. The relay logic and contactor logics (RLC) were practiced in the olden days which include the human intervention and errors. The advent and application of microprocessors, microcontrollers and new specific tools such as PLCs, Supervisory control and data acquisition (SCADA) and Distributed control systems (DCS) have increased productivity, accuracy, precision and efficiency. These systems reduced human intervention and increased the flexibility in the process control. The keyword automation clearly states that the working of a process or repetition in an efficient manner by incorporating mechanisms and control sequences in the proper order several times with acceptable deviations in the output of the process. |
