The module implements a triple modular redundancy (TMR) 2oo3 architecture using three independent processing channels to ensure fault-tolerant logic execution. Each channel scans inputs, performs safety calculations, and compares output states via the 25 Mbps hardware-synchronized TriBus inter-processor network. If any single channel experiences an operational variance or component failure, the internal hardware voting logic masks the faulty channel without interrupting active processes. This architecture ensures complete adherence to IEC 61508 SIL 3 specifications, executing a deterministic fail-safe state transition in the event of concurrent channel faults.
Q: What is the synchronization throughput between the three internal processor channels?
A: The three internal sub-processors maintain data synchronization over the dedicated TriBus network layer, executing hardware-level data verification at a continuous speed of 25 Mbps with integrated CRC error protection.
Q: Can a single faulty processor module be extracted while the system continues active safety logic operations?
A: Yes. The system supports full online hot-swap capabilities, allowing the extraction and replacement of an individual processor module without interrupting the 2oo3 voting sequence or dropping field I/O control loops.
Q: How does the hardware retain application variables during total external DC power loss?
A: The processor incorporates an 8 KB non-volatile random-access memory (NVRAM) block dedicated to the preservation of critical system states and retentive variables during power dropouts.
