Programming - Part 7

In part 7 of the PLC Basics series, learn about the operating cycle of a Programmable Logic Controller (PLC).

This video explains the operating cycle of a Programmable Logic Controller (PLC), which is fundamental to understanding how a PLC runs a user-developed program. The cycle includes an input scan, program scan, output scan, and maintenance tasks. The input scan reads and stores the value of input devices, while the program scan uses these stored values to solve the logic in each rung. The output scan transfers the output image to the external output circuits. The maintenance tasks include communication with other devices and internal checks.
