Triple Modular Redundancy and Fail-Safe State Execution

The hardware operates using a triple modular redundancy (TMR) 2oo3 architecture to execute continuous fault isolation and system logic validation. Three separate internal sub-channels execute user application programs concurrently, validating results through hardware voting circuits prior to updating output variables. This engineering design meets IEC 61508 SIL 3 safety standards, enforcing automatic fail-safe state execution upon detection of non-recoverable internal processor discrepancies or clock desynchronization. Internal diagnostic routines continuously sample hardware registers and verify data integrity across the dual RISC processor architecture to contain faults before they impact process safety functions.

Frequently Asked Questions

Q: How does the processor memory retain the application logic during a complete loss of external 24 VDC backplane power?

A: The module contains 16 MB of non-volatile RAM. When the input voltage drops below the 18 VDC minimum operating threshold, internal shutdown logic saves volatile operational variables directly into the non-volatile memory sector, preventing data corruption without requiring continuous external battery backup.

Q: What are the deterministic constraints when replacing an active 9802 processor module during online system operations?

A: The chassis backplane supports online hot-swap deployment. Inserting a replacement module triggers automatic background equalization, copying the active running memory state and application parameters from the remaining operational processors into the new module without affecting control loop execution timing or safety response deadlines.

Field Installation Guidelines

Chassis Insertion and Keying: Inspect the rear backplane connectors for pin alignment prior to installation. Insert the module into the designated slot rails of the Tricon chassis and apply steady force until the top and bottom mechanical ejector levers lock flush against the chassis frame.
Backplane Isolation and Grounding: Ensure the chassis enclosure connects directly to the master plant instrument ground using a low-impedance copper strap. Maintain separation between high-voltage power routing and the low-voltage communication cables attached to the RS-232/RS-485 interfaces to minimize signal interference.
Network Cable Termination: Connect Ethernet links using double-shielded twisted-pair (SFTP) Category 5e or Category 6 cables. Ground the cable shields strictly at the patch panel side or chassis grounding bar, leaving the field end ungrounded to avoid hazardous ground loops.
Firmware Verification Matrix: Confirm that the internal firmware build version of the incoming module matches the exact software version running on the paired active processors before switching the unit into active control mode.
