PLC Training course

Programmable logic controllers (PLCs) or programmable controllers are industrial computers that are durable and suitable for controlling manufacturing processes such as assembly lines, machines, and robotic equipment. Burraq Engineering Solutions is an engineering institute providing PLC training courses in Lahore Pakistan. PLCs can range from small modular devices with a few dozen inputs and outputs (I/Os) to large modular rack-mounted devices with several thousand I/Os that are often interconnected with other PLCs and SCADA systems are often interconnected with other PLCs and SCADA systems.

Digital and analog layouts

They can be designed with many digital and analog I/O layouts, extended temperature ranges, resistance to electrical noise, and resistance to vibration and shock. The programs used to control machine operation are usually stored in a battery or non-volatile memory. PLCs were first developed in the automotive manufacturing industry to provide flexible, powerful, and easily programmable controllers to replace hard-wired relay logic systems. Since then, they have become widely recognized as highly reliable automation controllers for use in harsh environments.

Electromechanical processes

PLC stands for Programmable Logic Controller. A PLC is a programmable computing device used to control electromechanical processes, often in the industry. A PLC is sometimes refer to as an industrial PC, a term that describes the main function of a PLC as a specialize industrial computing machine. PLCs are also use to transfer information from plant or off-site equipment to centralize applications, which usually run on a PC. PLCs are often use to monitor and report on equipment, diagnose faults in hardware equipment such as industrial machines and tools, and influence equipment events.

Relay logic systems

PLCs are the successor to relay logic systems, which are control systems that monitor and control low-level devices such as switches, relays, timers, actuators, and motors. In a relay logic system, relays perform logical operations by activating and deactivating magnetic coils in a circuit, called relay logic. Relays can be connect to circuits that use different currents and voltages, so historically they have been ideal for controlling and coordinating a wide range of industrial automation equipment.

The disadvantage of a relay logic system

The disadvantage of a relay logic system is that. like a switchboard, it is hard-wire and difficult to maintain due to the number of wires. The development of microcontrollers solve this problem. By making it possible to program relay logic processes and store them in a computer. The programming device is usually a PC, console, or handheld proprietary device. The I/O modules route the input signals to the PLC CPU, where the output signals are generate. The output data format is determine by the application program implement on the programming device.

Communication protocols

PLCs use a variety of ports and communication protocols to connect to control applications. Such as, supervisory control and data acquisition (SCADA) systems. Operators and line managers in industrial plants use HMIs to communicate with PLCs in real-time. HMIs are operator control panels, i.e. the interface between the human and the PLC. HMI allows operators to coordinate, control and manage industrial processes and equipment.

The PLC monitors

PLCs are use in various automate machine processes. Such as controlling lifts or turning lights on and off in intelligent buildings. PLC Training are use to monitor security cameras and automatic warning devices. Traffic lights, and industrial processes such as glass and paper cutting. The PLC monitors real-time data, such as equipment running times, operating temperatures, and usage statistics. It also starts and stops processes and generates alarms in the event of machine faults.

Traditional logic control systems

PLCs are use in product assembly, packaging, motion control, batch control, machine diagnostics and testing, and robotic processes. The advantages of PLCs are the main advantages achieve by eliminating the need for traditional fix logic control systems. PLCs are easier to build, install, maintain, and modify than traditional logic control systems. PLC components do not require complex wiring as the control logic is implement by software. Modifications and updates can be easily implement by uploading new ladder logic programs. Adjustments can be made remotely, rather than manually as with relay logic systems.

PLC programming

Ladder logic coding enables complex logic expressions to be develop quickly. PLC programming is relatively simple and because PLC systems are design to be modular. They can be install in a variety of physical environments. And can be easily expand with a number of different input and output devices. PLC Training are specially design devices that can withstand harsh environmental conditions. Such as, cold and extreme heat as well as the dust and humidity conditions found in factories.
