Automation For Everyone.

DCS is a control system build to control continuous control systems which are situated at different locations or for the operation of micro plants using a de-centralized Controller. Quite opposite to what PLCs and RTU do. All the subsystems are associated through the system for control, correspondence and checking.  Throughout the years, the term DCS has advanced from the first depiction for the abbreviation as a "Dispersed Control Systems" to the utilization of the expression "Decentralized Control Systems" and they appear to be to some degree compatible these days.  The key property of a DCS is its unwavering quality because of the circulation of the control handling around hubs in the framework. This mitigates a solitary processor disappointment. On the off chance that a processor fizzles, it will just influence one segment of the plant procedure, instead of a disappointment of a focal PC which would influence the entire procedure. This significance of registerin...

Supervisory Control & Data Acquisition is a computer system for gathering and analyzing real-time data.  SCADA systems are used to monitor and control a plant or equipment in industries such as telecommunications, water and waste control, energy, oil and gas refining, and transportation. SCADA is a system of software and hardware elements that allows industrial organizations to: Control industrial processes locally or at remote locations Monitor, gather, and process real-time data Directly interact with devices such as sensors, valves, pumps, motors, and more through human-machine interface (HMI) software Record events into a log file SCADA systems are crucial for industrial organizations since they help to maintain efficiency, process data for smarter decisions, and communicate system issues to help mitigate downtime . The basic SCADA architecture begins with programmable logic controllers (PLCs) or remote terminal units (RTUs). PLCs and RTUs are microcomputers that communic...

If you're into Automation you might have come across PLC commonly known as Programmable Logic Controllers. So what are they and how are they different than a Normal PC. Let's find out.. In old days, Relay logic was commonly used to operate a process plants.  C ontrol logic for manufacturing was mainly composed of relays, Cam timers, Drum sequencers  and  dedicated closed-loop controllers. Due to the hard wiring of relays it was a painstaking task for engineers to iterate the Logic and document it again in a proper form. A seriously tedious task.  To change this hardwire iteration problem engineers at Bedford Associates in 1969  developed a Programmable Logic Controller  so that the iteration could be carried out in software. Resulting in saving time and clumsy effort of rewiring.  PLC is a Controller designed to provide programming capabilities for controlling continuous processes while  withstanding harsh industrial environments. A PLC can be Pr...
