Fail-Safe Architecture and SIL3 Execution
The CPU module integrates dual INTEL 386EX 32-bit processors operating at 25 MHz to execute deterministic fail-safe logic routines. Galvanic isolation across internal buses prevents high-voltage transients from compromising processing hardware. Hardware self-tests execute continuously to verify system integrity and achieve SIL3 compliance under IEC 61508. Upon detecting an unrecoverable hardware fault or memory corruption event, internal diagnostic logic immediately forces control outputs into a defined fail-safe state to prevent unsafe process conditions.
Frequently Asked Questions
Q: How do the dual processors function within safety-critical loops?
A: Dual INTEL 386EX 32-bit microprocessors run identical safety logic in lockstep, comparing operational states continuously to isolate errors and trigger fail-safe execution when a mismatch occurs.
Q: What mechanisms enforce fail-safe state execution during internal system faults?
A: Integrated diagnostic circuits run hardware self-tests that detect processor divergence, memory parity faults, or power drops, driving output channels to a de-energized fail-safe condition.
Q: Does replacing an existing CPU module require power down of the entire rack chassis?
A: Maintenance procedures require removing power from the CPU slot to prevent electrical transients across the rack backplane during insertion or removal.
Field Installation Guidelines
Inspect the chassis backplane pins and card edge connectors for physical damage prior to installation. Ensure power is isolated before seating the module into its designated rack slot. Slide the card firmly along the slot guide rails until the backplane connectors lock completely. Fasten top and bottom retaining screws to ensure proper mechanical bonding and continuous chassis grounding. Route redundant Ethernet and fieldbus cables through dedicated raceways, separating low-voltage logic channels from high-voltage AC conductors to limit electromagnetic interference. Ground all cable shields at a single chassis ground bar to avoid floating potentials and ground loop currents.
