Description
Core Product Summary
The Rolls-Royce Marine SLIO 02 is a ruggedized distributed input/output (I/O) and network controller module belonging to the proprietary CanMan vessel control architecture. Engineered specifically for harsh marine operating environments, the SLIO 02 acts as a localized field node that acquires process telemetry, manages discrete/analog signals, and executes localized control routines for vessel propulsion systems.
Designed for installation across bridge consoles, engine control rooms, and thruster equipment spaces, the module establishes high-reliability data communication across redundant dual CAN bus channels. It enables real-time interaction between operator levers, main engines, fixed or controllable pitch propellers (FP/CP), and auxiliary propulsion units within unified marine automation networks.

Detailed Product Overview
The Rolls-Royce Marine SLIO 02 is a specialized distributed I/O controller module developed for the CanMan ship propulsion and steering control architecture. Engineered to fulfill classification society standards for marine equipment, the module processes critical analog and discrete signals associated with vessel propulsion machinery.
Constructed in a compact, industrial-grade metal enclosure, the SLIO 02 connects local field devices—such as hydraulic solenoids, position transmitters, speed pickups, and alarm contacts—directly to the ship’s control network. Its dual CAN bus communication interface provides hardware-level network redundancy, preventing loss of control during single-cable degradation or physical bus damage. By delegating signal processing to localized SLIO 02 nodes, the CanMan system reduces complex point-to-point cable runs throughout the vessel while maintaining fast response times for thruster and engine commands.
Applications & System Role
The Rolls-Royce SLIO 02 sits at the field actuation and signal acquisition layer of vessel propulsion systems. Positioned between primary bridge control levers and physical machinery actuators, it processes local engine speed feedback, propeller pitch position, and steering angles.
By digitizing field inputs and broadcasting them across the redundant CanMan dual CAN bus, the SLIO 02 enables centralized control computers and bridge displays to execute precise maneuvering routines for main propulsion engines, twin-screw setups, and auxiliary bow/stern thrusters.
