Automation Operations

Automation Operations

By Mitchell Williamson

Automation systems vary widely in design and purpose, they generally have a controller that is programmed or designed to make the machine components perform a series of actions or steps.​

Machine sequence can have a controller connected to various input and output devices and then programmed with logic.

Each step of a control system sequence starts with an input signal, or signals, the logic then decides what outputs to turn on or off, and outputs to turn on or off to make the machine step take place.​.

Basic Sequencing Control​

​Sequencing Continued

​To create a sequence of steps, the input devices are physically arranged on the machine so the completion of one step's action triggers an ipu device to sinal the controller to start the next step. The multi-step sequence is represented by a series of basic sequence models where the output of the previous step triggers an imput device to make the next step take place.
