The KONGSBERG RMP201-8 is a robust, high-density remote I/O module manufactured by Kongsberg Maritime, a global leader in marine and offshore automation systems. This module serves as a critical interface point in distributed control systems, enabling the connection of various field devices—such as sensors, switches, and actuators—to a central control unit over a network.
In the engine room of a large container ship, numerous temperature, pressure, and level sensors need to be monitored continuously. Running individual cables from each sensor to the central control room is impractical and costly. The KONGSBERG RMP201-8 is installed locally in a junction box near these sensors. It collects data from all connected field devices and transmits it digitally via a single network cable (e.g., CAN bus or Ethernet) to the central K-Chief automation system. This application solves the pain points of excessive wiring, signal degradation over long distances, and difficult troubleshooting, significantly enhancing the reliability and maintainability of the vessel's monitoring system.

· •Innovation Point 1: Distributed I/O Architecture for System Simplification. The core innovation of the RMP201-8 is its role in a distributed I/O system. By placing I/O conversion close to the field devices, it drastically reduces the amount of long, expensive analog wiring needed, minimizes signal noise, and simplifies system architecture, leading to lower installation and maintenance costs.
· •Innovation Point 2: High-Density, Configurable Channels. The module provides 8 channels that can be individually configured for different signal types (e.g., digital inputs for switch status, analog inputs for sensor values). This flexibility allows one module type to serve multiple purposes, reducing spare part variety and streamlining inventory management.
· •Innovation Point 3: Robust Design for Harsh Environments. The RMP201-8 is built to withstand the challenging conditions of marine and offshore applications, including resistance to vibration, humidity, salt spray, and electromagnetic interference. This ensures reliable operation where failure is not an option, directly contributing to vessel safety and operational continuity.
On a Floating Production Storage and Offloading (FPSO) vessel, monitoring the level in numerous cargo and ballast tanks is critical for stability and safety. The existing system suffered from unreliable analog signals due to long cable runs and electrical noise. By deploying KONGSBERG RMP201-8 modules near each tank group, the level transmitter signals were digitized locally. The digital data was then transmitted reliably to the control system. This retrofit resulted in a 99.9% availability of tank level data, eliminated spurious alarms, and provided more accurate data for the cargo calculation system, enhancing both safety and operational efficiency.
· •KONGSBERG RMP 201-4: A 4-channel variant of the remote I/O module, suitable for applications requiring fewer points.
· •KONGSBERG RIO-CI Communication Interface: A module that acts as a gateway, managing a network of multiple RMP201-8 modules and connecting them to the main automation system (e.g., K-Chief 600).
· •KONGSBERG DP System Controller: A dynamic positioning controller that can receive critical sensor data via remote I/O modules like the RMP201-8 for precise vessel control.
· •KONGSBERG Safety System Modules: Specialized modules for safety-critical functions (e.g., emergency shutdown) that can be integrated with standard I/O modules like the RMP201-8 within a unified architecture.
· •KONGSBERG Operator Stations: The HMI workstations that display the process data collected by the RMP201-8 modules to the ship's engineers.
