  1. PLC SCADA Training In Hands On Robotics

  2. PLC: • A PROGRAMMABLE LOGIC CONTROLLER (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices.

  3. PLC Process

  4. SCADA Supervisory control and data acquisition (SCADA) is a control system architecture that uses computers, networked data communications and graphical user interfaces for high-level process supervisory management, but uses other peripheral devices such as programmable logic controllers and discrete PID controllers to interface to the process plant or machinery.

  5. The operator interfaces which enable monitoring and the issuing of process commands, such as controller set point changes, are handled through the SCADA supervisory computer system. • However, the real-time control logic or controller calculations are performed by networked modules which connect to the field sensors and actuators.

  6. The SCADA concept was developed as a universal means of remote access to a variety of local control modules, which could be from different manufacturers allowing access through standard automation protocols. • In practice, large SCADA systems have grown to become very similar to distributed control systems in function, but using multiple means of interfacing with the plant.

  7. They can control large-scale processes that can include multiple sites, and work over large distances. • It is one of the most commonly-used types of industrial control systems, however there are concerns about SCADA systems being vulnerable to cyberwarfare/cyberterrorism attacks.

  8. SCADA Concepts • The key attribute of a SCADA system is its ability to perform a supervisory operation over a variety of other proprietary devices. • The accompanying diagram is a general model which shows functional manufacturing levels using computerised control. • Level 0,1,2,3,4.

  9. Level 0 contains the field devices such as flow and temperature sensors, and final control elements, such as control valves. • Level 1 contains the industrialised input/output (I/O) modules, and their associated distributed electronic processors. • Level 2 contains the supervisory computers, which collate information from processor nodes on the system, and provide the operator control screens. • Level 3 is the production control level, which does not directly control the process, but is concerned with monitoring production and targets. • Level 4 is the production scheduling level.
