Part 4: Installation & Configuration Guide

Phase 1: Preparation (≈10 minutes)

⚠️ Safety & Control Isolation

1. Coordinate planned maintenance and set process to a safe state.
2. Power down network and control racks, including redundant supplies.
3. Allow any capacitive loads to discharge before handling the module.

Tools & Documentation

• Anti-static wrist strap
• Screwdrivers and connector tools
• Cable labels + marker
• Photos of current wiring & connectors

Backup tasks:

• Record existing CAN cable labels and node addresses.
• Photograph current module position and connector orientations.

Phase 2: Module Removal (≈8 minutes)

1. Label each CAN and power cable at the connector.
2. Disconnect CAN bus and auxiliary connectors carefully.
3. Release module from mount or rack (backplane clip or screws).
4. Withdraw module straight out to avoid backplane damage.

⚠️ Inspect connectors, pins, and backplane bus for corrosion or bent pins.

Phase 3: New Module Installation (≈10 minutes)

1. Confirm correct part: CCN-11 Canman Controller Network.
2. With ESD protection, insert module into the slot.
3. Reconnect labeled CAN bus and power connections.
4. Verify connectors are seated and secured.

Checklist:

• Module correctly positioned
• All connectors match original labels
• CAN bus termination (if applicable) confirmed

Phase 4: Power-Up & Network Validation (≈15 minutes)

Before powering:

• Verify CAN bus wiring continuity and shield grounding.
• Check power rail levels with a digital multimeter.

Power-up sequence:

1. Apply controller power and allow initialization.
2. Observe communication status LEDs or diagnostics (if present).
3. Verify network connectivity using system diagnostics.
4. Confirm communication with SLIO or other network nodes.

Functional check:

• Run basic CAN node polling or diagnostic commands.
• Confirm no fault startups or bus errors.

If errors appear, check CAN termination resistors and node addressing.

 

Part 5: Customer Cases & Industry Applications

Case 1: Marine Propulsion Network Restoration

Situation: A commercial vessel’s CAN-based control network lost communication due to a failed CCN-11 node.
Task: Loss of network node caused alarm propagation and degraded propulsion interface.
Action: A Brand New Surplus CCN-11 was sourced and tested before dispatch.
Result: Replacement restored full network communication within hours, avoiding extended dock time and schedule disruption.

Case 2: Redundancy Planning on Offshore Platform

Situation: An offshore production platform used CanMan nodes for distributed I/O control. OEM lead times for controller nodes were long.
Task: Risk of single point failure necessitated spare planning.
Action: Recommended stocking min 1 + max 2 CCN-11 units with a reorder point at 1; detailed CAN node addressing tied to failure rates.
Result: Immediate failover enabled continued operation during scheduled maintenance.

Case 3: Ship Automation Retrofit

Situation: A fleet retrofit project needed consistent communication modules for unified CAN bus controls across vessels.
Task: Mixed CCN revisions caused integration mismatch.
Action: Verified firmware compatibility and provided matching CCN-11 nodes with documented node IDs.
Result: Integrated network operation achieved with stable CAN messaging and synchronized control loops.

 

Part 6: Frequently Asked Questions (FAQ)

Q1: What is the Rolls-Royce CCN-11 “Canman Controller Network”?
A: It’s a controller node module used in Rolls-Royce’s CanMan distributed automation platform, where multiple nodes communicate over dual CAN buses for real-time control in marine and industrial systems.

Q2: Is CCN-11 still manufactured by Rolls-Royce?
A: This appears to be a legacy automation module; production status is limited, and many units are sourced as surplus new or used stock.

Q3: What network protocol does it use?
A: CCN-11 communicates using CAN (Controller Area Network) buses with dual redundancy for robustness and safety in distributed control architectures.

Q4: Can this module be replaced live (hot swap)?
A: Hot replacement depends on system design. Most CAN-based control nodes are not hot-pluggable; power down before replacement if uncertain.

Q5: How should I plan spares for CCN-11?
A: Given limited production and lead time variability, a buffer stock strategy such as min 1 + max 2 modules with reorder at 1 is prudent to balance capital and availability risk.
