The SCADA system’s ability to notify the operator of an issue helps him to resolve it and prevent further loss of product. The operator reviews the data and discovers that Machine 4 was malfunctioning. The operator pauses the operation and views the SCADA system data via an HMI to determine the cause of the issue. The SCADA software processes, distributes, and displays the data, helping operators and other employees analyze the data and make important decisions.įor example, the SCADA system quickly notifies an operator that a batch of product is showing a high incidence of errors. PLCs and RTUs are microcomputers that communicate with an array of objects such as factory machines, HMIs, sensors, and end devices, and then route the information from those objects to computers with SCADA software. The basic SCADA architecture begins with programmable logic controllers (PLCs) or remote terminal units (RTUs). SCADA systems are crucial for industrial organizations since they help to maintain efficiency, process data for smarter decisions, and communicate system issues to help mitigate downtime.

Directly interact with devices such as sensors, valves, pumps, motors, and more through human-machine interface (HMI) software.

Monitor, gather, and process real-time data.

Control industrial processes locally or at remote locations.

Supervisory control and data acquisition (SCADA) is a system of software and hardware elements that allows industrial organizations to:

Ignition Exchange Community-made Ignition resources.

Ignition Maker Edition Made for hobbyist and educational use.

Ignition Edge Made for field and OEM devices at the edge.
