What is Modbus RTU health?
Healthy Modbus RTU traffic is consistent, repeatable, and free of unexplained errors. TorchScope measures health with timing, CRC, and transaction integrity metrics.
Signals of a healthy line
- Stable inter-frame timing with minimal jitter.
- Low CRC error rate relative to overall traffic volume.
- Consistent request/response pairs with predictable timeouts.
- No unexplained device ID duplication or framing mismatches.
TorchScope captures the raw wire data so the evidence behind each finding is replayable and auditable.
