Load Analysis Statistic Summary for WebSocket-S7 Protocol Bridge Performance

A 9.5 KB dataset containing performance metrics for industrial communication protocols. The data, authored by Mohammed Hlayel and last updated on 2026-05-11, compares WebSocket-S7, MQTT, OPC UA, and Modbus protocols for connecting Siemens S7 PLCs to cloud-hosted digital twins. It includes round-trip time (RTT) and response time measurements under single-user and multi-user loads.

Use Cases

• Benchmarking communication protocol latency based on the reported round-trip time (RTT) metrics.
• Evaluating protocol scalability for multi-user industrial systems based on the emulated load tests with up to 40 concurrent users.
• Comparing the performance of WebSocket-S7 against MQTT, OPC UA, and Modbus for deterministic cloud-PLC integration.
• Assessing protocol stability and error rates under wide-area network (WAN) conditions as described in the experimental validation.

Strengths

• Includes specific performance metrics: WebSocket-S7 achieved an average RTT of 87 ms, outperforming MQTT by 34.6%, OPC UA by 46.3%, and Modbus by 55.2%.
• Evaluates scalability with concrete numbers: WebSocket-S7 maintained sub-100 ms average response times for up to 40 concurrent users with near-zero error rates.
• Performance is judged against the IEC 61588 timing standard, providing an industry-relevant benchmark.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (9.5 KB), indicating a limited scope focused on summary statistics.
