The history of the PLC

PLC stands for Programmable Logic Controller and is a computer unit that was invented in 1968. It is a control unit for machines and plants, and in short consists of inputs and outputs. It receives signals through inputs and then activates outputs based on which inputs it has received. 

In 1968, the car manufacturer General Motors wanted a new control unit for cars. Therefore, General Motors made a tender with the requirements they had for the control unit. Bedford Associates therefore invented the PLC, which met the needs of a control unit at General Motors.

Today there is a large selection of PLCs in different looks and sizes from different manufacturers, e.g Allen-Bradley and Schneider, and the component is used in virtually all large plants and machines.
