ABSTRACT
Every industrial production process consists of a series of simple or complicated machines that, through the combination of raw materials, undergo a sequential transformation and integration in order to produce a final product. The whole set of machines, which are being integrated and combined in an industrial production process, will be referred as an "integrated machine". The operation control devices have two states of operation, OFF and ON, similar to the cases of the motors and the actuators. The control of the devices that are characterized as ON and OFF states is denoted as automation, and is being carried out by the utilization of automation circuits. Wiring diagrams are circuits representing both the power circuit and the automation circuit while, at the same time, representing the actual positioning of all the devices and components in the industrial installation, which is ideal information for the technician executing the wiring and overall installation.
