NORIMOS 4 – The High Performance
PLC-based Alarm, Monitoring and Control System

The N4 is a alarm, monitoring and control system (AMCS) for highest demands in operating comfort, usability, flexibility and system availability and is based on NORISYS 4 open automation platform. It is used to monitor and control ship technology, such as engines and other auxiliary systems. The N4 is a PLC (IEC 61131) based AMCS with decentrally placed subsystems. Each subsystem is operating independently with a high performance I/O CPU master and its slave units and is connected to the other subsystems. The system can be easily adapted to customer requirements.

​

  • Decentralised and PLC-based monitoring and control of engines and generators

  • Monitoring and control of auxiliary systems (e. g. pumps, valves, fans, etc.)

  • Visual and acoustic alarm triggering

  • Redundant interfaces (CANbus, Ethernet) and MODBUS interface for external systems

  • Self-monitoring function for the system

  • Functions:

    • Alarm list

    • Function groups

    • Graphical display of system statuses

    • Analysis tools: Trend monitoring

    • History: Alarm and event logging

    • Engine hours counter

  • Option: High-resolution, graphical visualisation (can be adapted to specific customer requirements) based on CODESYS

  • Option: Alarm extension components with duty alarm system for bridge, accommodation and mess rooms

  • Option: Integration of power management

  • Option: Integration of dead-man systems

The N4 is based on extremely robust components, can be used flexibly and furthermore, it can be extended with a comprehensive package of standard functions on request: whether as a simple data acquisition system, alarm and monitoring system, with additional control functions for pumps, valves and fans, or even fuel level measurement or power management – the N4 is the ideal companion for all aspects of monitoring, control and automation of shipboard propulsion systems and is approved by all conventional classification societies (ABS, BV, DNV-GL, LR, NK in preparation).

Advantages

  • Easy scalability: suitable for simple data acquisition systems, small monitoring systems, but also highly complex platform management systems (PMS)

  • Comprehensive package of standard functions, easy to adapt to customer requirements

  • Simple integration of and into third-party systems

  • Compatible with all NORIS systems: alarm extension system, duty alarm system, dead-man system, local gearbox control systems (LOPs), remote control systems, etc.

  • Web access for remote maintenance, data retrieval and central data storage (analyses, fleet management) and service

  • Visualisation with CODESYS

  • Fast and simple assistance thanks to a global service and sales network

  • Fast availability of spare parts guaranteed over many years

  • Approval from all common ship classification societies: ABS (BV, DNV, KR, LR, NK in preparation)
