Summary of CPU Frame Time for WebSocket-S7 Protocol Bridge Evaluation

A 5.5 KB Excel dataset summarizing CPU frame time metrics from an experimental validation of a WebSocket-S7 protocol bridge for real-time digital twin and PLC communication. The data was authored by Mohammed Hlayel and last updated on May 11, 2026. It likely contains performance measurements comparing WebSocket-S7 against MQTT, OPC UA, and Modbus protocols.

Use Cases

• Benchmarking communication protocol latency based on the reported round-trip time (RTT) comparisons.
• Evaluating real-time system performance under load based on the multi-user emulation results described.
• Analyzing CPU and memory resource usage for industrial automation software based on the mention of Unity Profiler metrics.

Strengths

• Provides specific performance metrics, including an average RTT of 87 ms for WebSocket-S7.
• Includes comparative data showing WebSocket-S7 outperformed MQTT by 34.6%, OPC UA by 46.3%, and Modbus by 55.2%.
• Reports sub-100 ms average response times for up to 40 concurrent users with near-zero error rates.

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 (5.5 KB), indicating limited scope.
