Control wiring diagrams are diagrams that show how electrical devices are connected and controlled by a controller. They can be used to guide the wiring of electrical components and terminals, as well as to troubleshoot a circuit. There are two main types of control wiring diagrams: wiring diagrams and line diagrams
Wiring diagrams
show the actual connection points for the wires to the components and terminals of the controller. They show the relative location of the components. They can be used as a guide when wiring the controller. For example, Figure 1 shows a typical wiring diagram for a three-phase magnetic starter.
Line diagrams
show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller. They are an ideal means for troubleshooting a circuit. For example, Figure 2 shows a typical line or schematic diagram.
SCADA system
A
SCADA system is a type of control system that allows you to monitor and control
industrial processes and equipment using computers, sensors, and network
communications. A SCADA
system consists of hardware components such as remote terminal units (RTUs),
programmable logic controllers (PLCs), gateways, edge computers, human machine
interfaces (HMIs), and servers, as well as software components that enable data
acquisition, analysis, display, and interaction. A SCADA system can help you improve
efficiency, safety, quality, and reliability of your operations
