Deterministic Fiber Mirroring & Backplane Bus Velocity
The module links primary and redundant secondary controllers across dedicated optical lines using fiber optic reflective memory technology. Operating over an integrated PCI interface, the card processes real-time memory mirroring independent of main processor scan cycles to maximize backplane bus communication velocity Licences. Dual LC SFP optical transceivers maintain deterministic 2.12 Gbaud data synchronization, enabling bumpless failover execution without process disruption. Onboard firmware flash compatibility ensures synchronized parameter exchanges between redundant chassis while continuous hardware diagnostics continuously monitor optical link integrity.
Frequently Asked Questions
Q: What happens to process control execution if one of the fiber optic cables connecting the primary and secondary RMX modules fails?
A: Dual LC fiber ports support redundant ring or parallel cabling topologies; if one link breaks, data synchronization automatically routes through the secondary optical path without interrupting CPU execution.
Q: Can the IC695RMX128-DG module be inserted or removed while the universal backplane is powered?
A: Hot-swapping requires pausing active redundancy synchronization via software prior to removal to prevent backplane bus fault conditions on the PCI bus interface.
Q: Is external power wiring required to operate the optical transceivers on the module front panel?
A: All operating current (~1.2 A at +3.3 VDC) is drawn directly from the RX3i IC695 universal backplane PCI rail without external auxiliary power wiring.
Field Installation Guidelines
- Power Isolation & ESD Precautions: Turn off backplane power prior to initial rack installation. Wear an ESD wrist strap attached to an unpainted metal grounding point before handling the circuit board.
- Rack Slot Placement: Seat the module into any open universal slot of the IC695 Universal Backplane, pushing firmly until top and bottom retention latches engage the metal frame.
- Fiber Optic Cable Connection: Insert multimode fiber optic patch cables equipped with duplex LC connectors into the front SFP cages until the locking clips click securely into position.
- Bend Radius & Cable Management: Maintain a minimum bend radius of 30 mm along fiber optic patch cables to prevent optical attenuation and packet loss during high-speed data transmission.
- Chassis Grounding: Connect the RX3i baseplate ground terminal to the main panel enclosure ground bus bar using heavy-gauge copper conductor wire to suppress high-frequency noise.
