Commonly Used Communication Protocols in SCADA Systems

SCADA systems utilize various communication protocols to facilitate data exchange between different components. Some commonly used communication protocols in SCADA systems include:

• MODBUS: A popular open-source, serial communication protocol that is widely used in industrial automation.
• DNP3: Designed for communication between various types of data acquisition and control equipment.
• IEC 61850: Standardized protocol for communication in power systems.
• OPC: A set of standards for industrial communication that allows different software applications to communicate.

Each of these communication protocols has its own specifications and advantages, and the choice of protocol depends on the specific requirements of the SCADA system.
