ESTUDO, PROJETO E DESENVOLVIMENTO DE UM PROGRAMA QUE AVALIA A COMUNICAÇÃO MODBUS ENTRE EQUIPAMENTOS

Abstract

The objective of this work is to study, design and develop a device that allows the user to simulate, evaluate and verify the Modbus communication between the Platform Management System (PMS) of the ship and the main equipment on board. This work will focus in particular on the ship's generators, where the available signals will be assessed. The signals, stipulated in the specification documents, are transmitted directly from the chosen equipment, the incoming signal should then be made available to the reception of the PMS. It is intended that the communication data between the PMS and the generator be simulated by developing a device that serves the purpose of verifying that each communication code corresponds to a sensor. This device is created using an Arduino Uno acting as a Modbus RTU slave and is programmed with a sample sensor/signal list from the generator sensor/signal list The objective of such equipment will be to fix in advance the possible programming errors and / or assembly errors that otherwise could only be detected at a later stage of the installation, and could therefore lead to increased costs and encompass delays to the final date for implementation.
