Get Started - SCADA Systems and RTU Panels
SCADA (Supervisory Control and Data Acquisition) systems are the backbone of modern industrial automation. They provide centralized monitoring and control of geographically dispersed assets, often spanning across large-scale facilities or entire regions. Think of them as the central nervous system of an industrial operation.
Key components of a SCADA system
RTUs (Remote Terminal Units)
Think of these as the ‘hands and feet’ on the ground. They are situated at remote locations, physically interacting with field devices like sensors, valves, and actuators. RTUs gather data and transmit it to the master SCADA station over a communications network.
PLC (Programmable Logic Controllers):
These act as specialized computers within a SCADA system. They handle local process control, often making decisions based on data collected by RTUs. PLCs then take action, controlling equipment or sending data back to the main SCADA system.
Communication Networks:
SCADA systems rely on reliable communication to connect the field components (RTUs, PLCs) with the central SCADA station. These networks can be wired, wireless, or use a combination of technologies depending on distances and environmental factors.
HMI (Human-Machine Interface):
This is a critical part, providing a visual representation of the process to the operators. The HMI displays real-time data, alarms, trends, and allows operators to interact with the system. Think of this as the ‘eyes and ears’ of the process for the operator.
