tecture, a LOP operates with acquisition unit and Human to Machine Interface (HMI) modules. They are used for

I/O, engine monitoring, controls, pumps, compressors ap- plications and are engineered to ensure marine standards’ compliance and feature technology to manage simultane- ously the functions of safety and shut down and condition monitoring, providing the vessel’s crew with a single inte- grated control system that’s easy to use.


The benefi ts provided by this technology are illustrated through two distinct applications: The fi rst one is a vessel featuring a single propulsion engine where the redundancy of the controller is compulsory. In this instance, one of the most important criteria that the LOP has to satisfy is the capability to manage at the same time, and in real time, dual controllers – the CMR device is equipped with two CAN networks, enabling the system to continuously manage the parameters of the electronic control modules (ECM), monitor the communications and display the main controller parameters on the engine.

The second example concerns the numerous requests for simultaneously managing several communication proto- cols available on engines or ships - CANopen / SAEJ1939 / Modbus TCP/IP / Ethernet which are all embedded on

CLARINUX SW, SIMS’ OS allows LOP to manage the communication with engine parameters (T°/Pressure/

Speed) through I/O modules, ECM and sometime the pro- pulsion system by reading and writing messages both ways.

LOP systems have been supplied by CMR to many cus- tomers of the world’s leading controllers manufacturers including Bosch, Woodward, Heinzmann, Caterpillar and

MTU. CMR Group supplies instrumentation and controls for offshore platforms and vessels, marine, engines and in- dustrial applications around the world. With core product groups including rugged cable systems, controls, custom products, electronics, alarm monitoring and safety systems, industrial sensors, and software, the CMR Group is an en- gineering partner for the world’s leading manufacturers.

Alain Meslati joined CMR in 1989, and today focuses on engine builders, mostly in

High and Medium speed Diesel and Gas engine in Europe, North America and Asia.

Patrice Flot was hired at CMR France in 2005, as an Operations Manager. He was in charge

R&D, Production, Design, and Technical departments.

He became Managing Director in Dec 2006.
