Sugar-Energy Plant

Advanced automation for machines and industrial processes

Altus technology was deployed to modernize the boilers and scrubbers used in the production process of a leading company in Brazil’s sugar-energy sector.

The project enhanced process control, improved operational reliability, and optimized energy efficiency, contributing to higher productivity and greater environmental performance across the plant.

Modernization of a Sugarcane Processing Plant

Sustainability is more than a trend, it is a commitment to building a better future. In the sugarcane and bioenergy sector, the production of food, fuel, and renewable energy from biomass is already a consolidated reality.

A São Paulo–based company operating in this segment sought to further strengthen its competitiveness by automating its integrated production system for sugar, ethanol, and bioenergy derived from sugarcane. As one of Brazil’s most traditional and economically significant raw materials, sugarcane plays a vital role in supplying the domestic market and supporting exports worldwide.

With the support of an Altus-certified system integrator, the company implemented NX Series controllers to optimize machine performance, improve process stability, and increase operational efficiency. This modernization initiative enabled the company to maintain its position among the leading global players in the sugar-energy industry while reinforcing its commitment to sustainable production.

High availability

The system features NX3030 CPUs running in hot standby redundancy mode

Flexible development

Nexto System technology enables the development of customized programs for special use cases

Distributed system

The application is powered by robust Nexto CPUs acting as remote units, enhancing the system’s control capabilities

Multiprotocol application

The solution integrates different communication networks, such as Profibus and Modbus, for device command and data exchange

Redundant and Flexible System

The flexibility of Nexto CPUs allows for not only redundancy but also the option to develop local programming for special use cases. All CPUs feature a multitasking, preemptive operating system. Additionally, their 32-bit RISC PowerPC processor combines high performance with lower energy consumption. It is free of moving parts, contributing to a higher mean time between failures (MTBF).

Through its programming tool, the MasterTool IEC XE software, field networks like PROFIBUS can be integrated with communication protocols such as IEC 61131-3. This allows the user to configure all parameters in one place, accelerating development and reducing engineering costs. The MasterTool also enables the reuse of code developed in previous solutions, allowing users to convert applications between graphical languages and reuse them in other opportunities

Scope of services provided

The project to automate five boilers and two gas scrubbers, which are critical to both energy production and environmental protection, involves a redundant high-availability system with two NX3030 CPUs and six remotes: one NX3020 and five NX3010, communicating via Modbus TCP. The remotes are distributed among the boilers and scrubbers.

This application features 350 digital I/O points, approximately 240 analog points, and a control panel (CCM). In addition to Modbus TCP communication between the main control system (NX3030 CPUs) and the remotes (NX3010 and NX3020), a PROFIBUS network is used for interfacing with the CCM. This versatility and support for multiple protocols within the same project allow for rapid application development, meeting the client’s demands and enabling them to focus on other critical tasks at the plant.
