Network Traffic Data for PLC-Digital Twin Protocol Performance Comparison

Network packet traces captured by Wireshark during an experiment comparing communication protocols for industrial automation. The data supports a study by Mohammed Hlayel that introduced a WebSocket-S7 bridge for connecting Siemens PLCs to cloud-hosted digital twins, last updated on May 11, 2026. The dataset is small, at 5.5 KB, and is stored in an XLS file format.

Use Cases

• Benchmarking round-trip time (RTT) performance of industrial protocols like WebSocket-S7, MQTT, OPC UA, and Modbus.
• Analyzing network traffic patterns and stability under single-user and multi-user emulated loads.
• Validating communication architectures against real-time thresholds defined by standards like IEC 61588.

Strengths

• Includes performance metrics like average RTT (87 ms for WebSocket-S7) and comparisons against other protocols (34.6% lower than MQTT).
• Describes a multi-user scalability test with up to 40 concurrent users and sub-100 ms response times.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• The dataset is very small (5.5 KB), suggesting limited scope or a summary of results rather than raw packet data.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
