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.
