SIL3 Logic Verification and Fail-Safe State Execution
The dual Intel 386EX 32-bit microprocessors execute safety logic in lockstep mode at a 25 MHz clock frequency. Internal optocouplers and isolation barriers maintain galvanic isolation between core processing circuits and external bus noise. Integrated diagnostic routines execute continuous cross-comparison tests across both microprocessors to verify memory integrity and arithmetic logic calculations. If an unrecoverable hardware discrepancy occurs, internal hardware watchdog circuits trigger immediate fail-safe state execution, isolating the processor and forcing output channels to a de-energized shutdown state in accordance with SIL 3 certification rules under IEC 61508.
Frequently Asked Questions
Q: How do the dual processors maintain lockstep execution during real-time operations?
A: Both 32-bit Intel 386EX microprocessors process identical safety logic concurrently while hardware comparison logic verifies data state alignment at every clock cycle to detect divergence instantly.
Q: How does internal power loss affect stored user programs in flash memory?
A: Non-volatile Flash-EPROM retains the 1 MB operating system and 512 KB user program without requiring external battery backup, preventing data corruption during backplane power disruptions.
Q: What action occurs if the module detects an internal RAM memory parity error?
A: Continuous self-diagnostic circuits detect the parity error, lock processor execution, and drive the system output subsystem directly into its defined safe state to maintain SIL 3 integrity.
Field Installation Guidelines
Isolate all power feeds to the chassis prior to inserting or removing the module. Align the PCB edge connectors with the rack guide rails, pushing the assembly firmly into the backplane until the front retaining latch engages completely. Tighten all mechanical chassis screws to establish a firm ground connection and prevent vibration-induced disengagement. Route communication cables through independent wire ducts, maintaining adequate physical separation from high-voltage AC cables. Terminate all shielded data lines at the designated chassis grounding point using 360-degree ground clamps to suppress electromagnetic interference and prevent ground loop currents from destabilizing processing logic.
