The wide range of communication modules available in Nexto Series gives our advanced family of programmable controllers the possibility of meeting the most varied demands of the international industry. With advanced features such as hot swapping, expansion of I/O modules and scalar architecture based on deterministic Ethernet, the series equipment can be used both on machines and distributed systems. Recently, this adaptability and the ability to act on different processes led Nexto technology to be used as a central piece in the upgrade of one of the company's production plants ArcelorMittal, multinational metallurgical company.
Present in more than 60 countries in Asia, Africa, Europe and the Americas, ArcelorMittal is a leader in the main steel markets, including the construction, automotive, household appliances and packaging segments, in addition to the Research & Development of new technologies. With the aim of strengthening its presence in the South American market of metallurgy the company sought technologies that could guarantee the quality of its products and enhance the capacity of its wire manufacturing unit in Juiz de Fora/MG. In this project, Altus equipment was used in the retrofit of the multipass drawing machine with winder and in the five baking ovens used in the wire production process sold in the annealed wire market .
The CPU chosen to optimize both the drawing machine and the baking ovens was the model NX3005, unit with integrated power supply , high processing speed – there are 1000 Boolean instructions (contacts) every 6 microseconds – and large data storage capacity. In addition to these features that guarantee its high performance, the Nexto Series CPU also supports WebServer, free tool that allows the creation of screens for supervision and application monitoring. With the resource, which is already integrated into the unit, you do not need to invest in purchasing and implementing a SCADA system, which adds even more agility and savings to application development.
The complete automation of the plant's new control system uses six CPUs, a remote MODBUS/TCP NX5100 and a set of modules that total more than 2300 I/O points to control the machine and the five ovens cooking. The architecture also features a JN3008 media converter from the Connect and a seven-inch HMI from the X2-BASE.
