Nexto Series Features
Nexto Series is a powerful and complete Programmable Logic Controller (PLC) series with exclusive and innovative
features. Due to its flexibility, functional design, advanced diagnosis resources and modular architecture, Nexto PLC can be
used for control systems in small, medium and large 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 applications such as high speed control for small ma-
chines, complex distributed processes, redundant applications and systems with a large number of I/O as building automation.
Furthermore, Nexto Series has modules for motion control, communication and interface to 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, allowing input and output
information and data to be shared among all modules of the system. The I/O modules can be easily divided and distributed
throughout the whole field, allowing the use of bus expansion with the same performance of a local module.
Furthermore Nexto Series presents a complete tool for user programming, configuring, simulation and debug: MasterTool
IEC XE. It’s flexible and easy-to-use software which offers six programming languages defined by IEC 61131-3 standard:
Structured Text (ST), Sequential Function Chart (SFC), Function Block Diagram (FBD), Ladder Diagram (LD), Instructions
List (IL) and Continuous Function Chart (CFC). MasterTool IEC XE allows the use of different languages in the same appli-
cation providing to the user a powerful way to organize the application and reuse codes from previous applications.
Other modules of Nexto Series made the Nexto Jet solution, which is an ideal set of inputs and outputs for small and
medium application size, beyond distributed systems. The solution presents high performance and compact modules that are
used together with the CPUs, racks, communication and fieldbus modules, besides MasterTool IEC XE software. The Nexto Jet
modules add more versatility and competitiveness to the consecrated Nexto Series, keeping the flexibility, modular architecture
and advanced diagnosis resources.
