Profinet / EtherNet/IP Deterministic Networks & Firmware Flash Compatibility
The IC695RMX128 establishes a synchronized physical link between primary and backup controllers using high-speed 2.12 Gbaud optical hardware channels. This module operates independently of standard Profinet / EtherNet/IP deterministic networks, bypassing traditional network routing blocks to move internal system states directly from the master processor backplane to the hot-standby node.
Ensuring proper hardware operation requires strict validation of the firmware flash compatibility matrix across both redundancy modules and the host controllers. Any mismatch in firmware revisions will degrade the backplane bus communication velocity, leading to variable synchronization latencies or unexpected failure of the bumpless transfer routine during an active hardware switchover event.
Frequently Asked Questions
Q: Does the IC695RMX128 support Hot Module Insertion and Removal (RIUP)?
A: Yes. The hardware design allows the module to be inserted or removed under power without disrupting active backplane operations or degrading the execution cycles of the adjacent modules on the rack.
Q: How does the module handle communication integrity across long-distance redundancy layouts?
A: The module utilizes dedicated single-mode fiber-optic LC links combined with hardware-based network error detection. This protects the dynamic data packet transfer from electromagnetic interference and guarantees deterministic data alignment between the redundant racks.
Q: What is the significance of the dynamic packet size parameter on this module?
A: The dynamic packet size execution is controlled by the companion RMC128/RMX228 memory manager hardware. It scales the size of the transferred data block to match the specific memory allocation modified during each CPU scan, optimizing the overall backplane data throughput.
Field Installation Guidelines
- Fiber Optic Handling: Do not bend the single-mode fiber cable past its minimum specified bend radius. Ensure the LC type optical connectors are free of dust and contaminants prior to insertion into the transceiver module.
- Module Retention: Align the module card with the designated universal RX3i chassis slot, press backward until the rear interface seats firmly in the backplane, and engage the locking clips to secure the device frame.
- Conduit Isolation: Route the single-mode fiber connections and adjacent system cables away from heavy three-phase AC distribution lines, motor drives, or inductive loads to prevent mechanical damage and exposure to extreme localized heat.
- Thermal Venting: Maintain standard mechanical spacing clearances above and below the rack array to permit unrestricted ambient convection across the IP20 housing components.
