1. INTRODUCTION
1. Introduction
Nexto Series programmable controllers are the ultimate solution for industrial automation and system control. With high
embedded technology, the products of the family are able to control, in a distributed and redundant way, complex industrial
systems, machines, high performance production lines and the most advanced processes of Industry 4.0. Modern and high-
speed, the Nexto series uses cutting-edge technology to provide reliability and connectivity, helping to increase the productivity
of different businesses.
Compact, robust and with high availability, the series products have excellent processing performance and rack expansion
possibilities. Its architecture allows easy integration with supervision, control and field networks, in addition to CPU and power
supply redundancy. The family’s equipment also offers advanced diagnostics and hot swapping, minimizing or eliminating
maintenance downtime and ensuring a continuous production process.

1.1. Nexto Series
Nexto Series is a powerful and complete series of Programmable Controllers (PLC) with exclusive and innovative charac-
teristics. Due to its flexibility, functional design, advanced diagnostic resources and modular architecture, the Nexto PLC can
be used to control systems in small, medium and large scale applications.
Nexto Series architecture has a great variety of input and output modules. These modules combined with a powerful 32
bits processor and a high speed bus based on Ethernet, fit to several application kinds as high speed control for small machines,
complex distributed processes, redundant applications and systems with a great number of I/O as building automation. Further-
more, Nexto Series has modules for motion control, communication modules encompassing the most popular field networks
among other features.
Nexto Series uses an advanced technology in its bus, which is based on a high speed Ethernet interface, allowing input and
output information and data to be shared between several controllers inside the same system. The system can be easily divided
and distributed throughout the whole field, allowing the use of bus expansion with the same performance of a local module,
turning possible the use of every module in the local frame or in the expansion frames with no restrictions. For interconnection
between frames expansions a simple standard Ethernet cable is used.
