What is a PLC?
What is a PLC? A PLC, or Programmable Logic Controller, is a computer built to function reliably under the tough conditions of industrial environments like extreme temperatures or dusty areas. It automates processes in industries, including manufacturing and wastewater treatment.
PLCs share many features of the personal computer you have at home. They both have a power supply, a CPU (Central Processing Unit), inputs and outputs (I/O), memory, and operating software (although it’s a different operating software).
The biggest differences are that a PLC can perform discrete and continuous functions that a PC cannot do, and a PLC is much better suited to rough industrial environments. A PLC can be thought of as a ‘ruggedized’ digital computer that manages the electromechanical processes of an industrial environment.
PLCs play a crucial role in the automation field, forming part of a larger SCADA system. A PLC can be programmed according to the operational requirements of the process. In the manufacturing industry, reprogramming will be needed due to the change in the nature of production. To overcome this difficulty, PLC-based control systems were introduced. We’ll first discuss PLC basics before looking at the various applications of PLCs.
If you want to learn how to programme PLCs, you should check out some of the different online PLC training courses. These courses can help jump-start your career in control engineering.
Falmouth (/ˈfælməθ/ FAL-məth; Standard Written Form: Aberfala[2]) is a town, civil parish and port on the River Fal on the south coast of Cornwall, England, United Kingdom.[3] It has a total resident population of 21,797 (2011 census).
In 1540, Henry VIII built Pendennis Castle in Falmouth to defend Carrick Roads. The main town of the district was then at Penryn. Sir John Killigrew created the town of Falmouth shortly after 1613.[7]
In the late 16th century, under threat from the Spanish Armada, the defences at Pendennis were strengthened by the building of angled ramparts. During the Civil War, Pendennis Castle was the second to last fort to surrender to the Parliamentary Army.[8]
After the Civil War, Sir Peter Killigrew received royal patronage when he gave land for the building of the Church of King Charles the Martyr, dedicated to Charles I, "the Martyr".[9]
