Programmable L[ogic Controllers PLCs are the micro processor controller devices situated at the remote sites of the plant or at the field of the process systems. PLCs purpose is to monitor the process parameters located at the field and adjust the outputs based on the inputs received by the PLCs. PLCs will operate on any systems which will have input field devices that are On-Off type discrete or digital or analog input devices. Similarly it will operate on the field devices which will be discrete or analog output type.

With this article, we will continue with where our previous article, What are the leading Industrial Automation Job types? The job description and degree of responsibilities vary and so you should align your capabilities with the experience required. PID controllers maintain the output to a device so that there is zero error between process variable input and setpoint to the device. Answer: a PLC or programmable logic controller is a ruggedized computer used for automating processes. A DCS or distributed control system is similar to a PLC in that it has rugged computer controllers however the DCS contains multiple autonomous controllers that are distributed throughout a system, also used for automating processes.
