PLC SCADA

Course Description

PLC (Programmable Logic Controller): PLC stands for Programmable Logic Controller. This controller is best to used for industrial automation. In PLC we give a set instruction to this controller through programming which it follows throughout life span. These controllers can automate a specific process, machine function, or even an entire production line.

• Functionality: PLCs are industrial digital computers specifically designed for controlling manufacturing processes, such as assembly lines, robotic devices, or any activity that requires high-reliability control and ease of programming.
• Programming: PLCs are programmed using ladder logic or other IEC 61131-3 standard programming languages. The programming is done to control the inputs and outputs of the system based on logic and timing functions.
• Inputs and Outputs: PLCs interface with sensors and actuators in the industrial environment. Inputs (sensors) provide information about the process, and outputs (actuators) control the various elements of the process.
• Reliability: PLCs are known for their ruggedness and reliability in harsh industrial environments.

2. SCADA (Supervisory Control and Data Acquisition): Supervisory Control And Data Acquisition (SCADA) is the best 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 is the top rated analyzing software in the automation field.

• Functionality: SCADA systems are used for monitoring and controlling processes in real-time. They gather, process, and display real-time data, providing a graphical interface for operators to monitor the status of the industrial processes.
• Data Acquisition: SCADA systems collect data from various sensors and devices connected to the industrial process. This data is then processed and displayed in a human-readable format.
• Visualization: SCADA systems provide graphical representations of the industrial processes, allowing operators to visualize the entire system. This can include real-time trends, alarms, and historical data.
• Control: While PLCs handle the direct control of devices, SCADA systems provide a higher-level interface for operators to monitor and control the overall process. Operators can make adjustments and control the system remotely.
