Investigating and analyzing the performance of industrial automation and (PLC)

Before the advent of industrial automation, manufacturing plants consisted of separate departments that operated completely separately and communication was done by operators. This form of production has many problems and has many limitations. Industrial automation is equivalent to controlling and guiding a device in an automated industry. It was for the first time in ۱۹۱۳ that Ford company used industrial automation in one of its assembly production lines, and for this reason, Ford is considered to be the leader of this issue in the history of automation.With the passage of time, programmable controllers or in English abbreviations (PLCs) were used. In simple language, PLC is a device with logic programming capability that can feed data as input to the device, process on them and finally control or display outputs.Industrial automation can be used in extensive areas. Controllers are the heart of automation that changed industrial automation in ۱۹۶۸ with the advent of the PLC. Early PLCs were often used in automotive factories. Nowadays, wherever the controller needs, the traffic lights to the power plant are used because of the many PLC applications. One of the most positive PLC applications is the rehabilitation of patients who have lost their ability to move for some reason. After the various movements are specified and used by the dynamic simulation analysis, PLC is used. Then, with PLC planning, the robot is controlled.[۱]With the advent of microprocessors, the control of different units of a factory or industrial unit, instead of being controlled separately, are controlled centrally by a small computer. In this case, all the control circuit systems, including contactors, relays, timers and other controlling components, do not change, but the sensors receive information from different points and process the information and issue the necessary command to the industrial unit.[۹]
