Specification Parameters
Model and version
The model number of this marine controller is H1111.0203, which represents a unique design idea and function setting in the Rolls-Royce marine controller product matrix. It is equipped with PIC code version 2.2, which has been continuously optimised and has more precise control logic, which can greatly improve system compatibility and provide solid guarantee for the coordinated operation of marine equipment.

Communication Frequency
Although the current public information has not yet disclosed the specific communication frequency of H1111.0203 marine controller, it can be seen by referring to the Rolls-Royce products of the same type that its communication frequency must have been professionally and finely tuned. In this way, it can operate stably in the complex and changeable electromagnetic environment of the ship and smoothly realise high-speed and reliable data transmission and command interaction with all equipments of the ship, which can strongly guarantee the efficient operation of the ship control system.

Other Parameters
Due to the limitations of the available information, the specific parameters of the controller in terms of size, weight, working voltage, etc. are not clear for the time being. However, according to Rolls-Royce’s consistent design concept, its structural design will definitely take into account the compact layout and durability. Not only can it be cleverly adapted to the limited installation space of the ship, but also can maintain stable and reliable performance under the harsh marine environment.
Skills

High reliability and stability
Rugged protection design
H1111.0203 marine controller shell selection of high-strength, corrosion-resistant special alloy materials, the face of seawater erosion, salt spray corrosion and humid air intrusion, can easily cope with. Even in the harsh marine environment for a long time, it can effectively prevent the shell from rusting and deformation, and build a reliable physical protection barrier for the internal precision electronic components. At the same time, the internal circuitry is reinforced with advanced potting technology, which significantly enhances vibration and shock resistance, significantly reducing the risk of failure caused by ship bumps and shaking, and ensuring that the controller’s performance is always stable during long-term operation.

Excellent anti-interference ability
There are many electronic equipments on the ship, and the electromagnetic environment is complicated. This controller is equipped with multiple electromagnetic shielding measures, from the careful layout of the circuit board to the overall structure of the shield cleverly designed to isolate the external electromagnetic interference on the internal circuit. At the software level, it adopts advanced anti-interference filtering algorithms, monitors and processes input and output signals in real time, and automatically screens and rejects interfering signals to ensure that the instructions received and sent by the controller are accurate, thus realising the stable control of marine equipment.

Precise Intelligent Control
Advanced control algorithm
The controller has built-in advanced control algorithms based on Rolls-Royce’s many years of technological accumulation and R&D crystallisation. It can quickly and accurately calculate the optimal control parameters of the ship’s equipment according to the actual running state of the ship, the feedback data from real-time sensors and the commands given by the operator. Whether it is to adjust the engine speed according to different sailing speeds and load requirements, or to accurately control the rudder angle to achieve the ship’s steering, H1111.0203 Marine Controller is able to perform its tasks with high precision, ensuring that the ship can maintain optimal operating conditions under all kinds of working conditions.

Intelligent sensor co-operation
The controller cooperates with various high-precision sensors such as speed sensors, pressure sensors and position sensors on the ship. By collecting and analysing the sensor data in real time, it can fully grasp the operating conditions of the ship’s equipment, make intelligent decisions and control accurately according to the preset procedures and algorithms. For example, it can automatically and flexibly adjust the engine power and rudder operation when it detects changes in the sea conditions to ensure the safety and stability of the ship’s navigation.

High compatibility
Rich hardware interface
H1111.0203 marine controller is equipped with a rich variety of standardised hardware interfaces, common RS-232, RS-485 serial communication interface, CAN bus interface, as well as all kinds of analog and digital input and output interfaces. With the help of these interfaces, it can be conveniently connected to the engine control system, generator control system, navigation system, steering control system and other equipment on the ship to achieve physical connection, and smoothly realise data sharing and collaborative operation among different equipment.

Wide range of software protocol support
At the software level, the controller supports MODBUS, PROFIBUS and other general industrial communication protocols, as well as specific communication protocols for the marine industry. This enables it to work seamlessly with different brands and models of marine equipment without the need for cumbersome interface conversion or custom development, which greatly improves the efficiency and flexibility of marine system integration and effectively reduces system construction costs.
Convenient Maintenance

Modular design
The controller adopts modular design concept, divided into power supply module, communication module, control computing module, input and output module and other functionally independent modules. Once a module fails, maintenance personnel can quickly locate the problem and directly replace the corresponding module, without the need for large-scale disassembly and testing of the entire controller, significantly shortening the maintenance time and reducing the difficulty and cost of maintenance.

Intelligent Fault Diagnosis
It has a built-in intelligent fault diagnosis system, which can monitor and analyse its own operation status in real time. Once a fault is detected, the system instantly generates a detailed fault report covering the type of fault, the location of the fault, the possible causes and other key information. Maintenance personnel can quickly read the fault report through the controller’s own display, or connect to external computers and other equipment, and carry out targeted maintenance work, significantly improving the efficiency of fault detection and repair.
