SCADA Protocol Analyzer

SCADA Protocol Analyzer is a professional-grade application designed for engineers, technicians, and automation specialists who need to decode, analyze, and troubleshoot industrial communication protocols used in modern SCADA and OT environments.

The application provides powerful decoding capabilities for widely used protocols such as Modbus (RTU and TCP), DNP3 (Master/Outstation), and IEC 60870-5-104 as well as IEC 101. It enables real-time interpretation of communication frames with a clear, structured breakdown of each field, including device address, function code, payload data, and CRC validation.

Built with a strong focus on field usability, SCADA Protocol Analyzer allows users to quickly identify communication issues, protocol inconsistencies, and data errors. The decoding engine is optimized for performance, ensuring fast processing of frames even in high-traffic environments. Advanced error detection mechanisms highlight issues such as invalid CRC, malformed frames, incorrect lengths, and unsupported function codes.

The intuitive interface provides a seamless user experience with real-time decoding windows, structured visualization of protocol layers, and easy navigation between frames. Whether you are commissioning a new SCADA system, diagnosing communication problems in RTUs or IEDs, or validating protocol exchanges in an industrial network, this tool significantly reduces troubleshooting time.

SCADA Protocol Analyzer is also a valuable learning and training tool for understanding industrial protocols. It offers detailed field-by-field decoding, making it easier to study how protocols like Modbus, DNP3, and IEC 104 operate in real-world scenarios.
