Automation of factory or manufacturing or process plant improves production rate through a better control of production. It helps to produce mass production by drastically reducing assembly time per product with a greater production quality. Therefore, for a given labor input it produces a large amount of output.

Industrial Process Automation Systems

Supervisory control and data acquisition SCADA is a control system architecture comprising computers , networked data communications and graphical user interfaces GUI for high-level process supervisory management, while also comprising other peripheral devices like programmable logic controllers PLC and discrete proportional-integral-derivative PID controllers to interface with process plant or machinery. The use of SCADA has been considered also for management and operations of project-driven-process in construction. The operator interfaces which enable monitoring and the issuing of process commands, like controller set point changes, are handled through the SCADA computer system. The subordinated operations, e. The SCADA concept was developed to be a universal means of remote-access to a variety of local control modules, which could be from different manufacturers and allowing access through standard automation protocols. In practice, large SCADA systems have grown to become very similar to distributed control systems in function, while using multiple means of interfacing with the plant.

A distributed control system DCS is a computerised control system for a process or plant usually with many control loops , in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers located at a central control room or within a central computer. The DCS concept increases reliability and reduces installation costs by localising control functions near the process plant, with remote monitoring and supervision. Distributed control systems first emerged in large, high value, safety critical process industries, and were attractive because the DCS manufacturer would supply both the local control level and central supervisory equipment as an integrated package, thus reducing design integration risk. Today the functionality of SCADA and DCS systems are very similar, but DCS tends to be used on large continuous process plants where high reliability and security is important, and the control room is not geographically remote. The key attribute of a DCS is its reliability due to the distribution of the control processing around nodes in the system. This mitigates a single processor failure.

Process control systems PCS , sometimes called industrial control systems ICS , function as pieces of equipment along the production line during manufacturing that test the process in a variety of ways, and return data for monitoring and troubleshooting. Many types of process control systems exist, including supervisory control and data acquisition SCADA , programmable logic controllers PLC , or distributed control systems DCS , and they work to gather and transmit data obtained during the manufacturing process. The PCS can be a relatively simple item with a sensor, often called a primary transducer, that receives an input, along with a controller that processes the input, and a receiver that processes an output. More complicated PCS devices are robotic and perform many tasks. A great number of measurements can be taken on production lines. An equipment's sensor can pick up many measurements including pressure, flow rate, density, acidity, velocity, speed, stress, temperature, and weight.

Он не заметил в АНБ ни одного существа женского пола. - Вас это смущает? - раздался у него за спиной звонкий голос. Беккер обернулся и тотчас почувствовал, что краснеет.

Description

Голос показался ему отдаленно знакомым. Он попытался определить акцент - может быть, Бургос. - Вы набрали правильно, - сказал он осторожно, - но это служба сопровождения. Звонивший некоторое время молчал. - О… понимаю. Прошу прощения.
