Product Description
Nexto Series is a powerful and complete Programmable Logic Controller (PLC) with unique and innovative features. Due to its
flexibility, smart design, enhanced diagnostics capabilities and modular architecture, Nexto PLC can be used for control
systems in medium and high-end applications or in high speed machinery

already available on Nexto CPUs or in applications where is necessary a high availability of automation system with uses of
network redundancy.
Its main features are:
Simultaneous support to MODBUS TCP and MODBUS RTU over TCP
Simultaneous operation as MODBUS master/client and server/slave
Redundant architecture support (half-cluster)
Network redundancy support (NIC teaming)
Hot swap support
Auto crossover Ethernet Interface

Innovative Features
Nexto Series brings to the user several innovations in utilization, supervision and system maintenance. These features were
developed focusing a new experience in industrial automation. The list below shows some new features that users will find in the
NX5000 module:
One Touch Diag: One Touch Diag is an exclusive feature that Nexto Series brings to
PLCs. With this new concept, the user can check diagnostic information of any module
present in the system directly on CPU’s graphic display with one single press in the
diagnostic switch of the respective module. OTD is a powerful diagnostic tool that can be
used offline (without supervisor or programmer), reducing maintenance and commissioning
times.
ETD – Electronic Tag on Display: Another exclusive feature that Nexto Series brings to PLCs is the Electronic Tag on
Display. This new functionality brings the process of checking the tag names of any I/O pin or module used in the system
directly to the CPU’s graphic display. Along with this information, the user can check the description, as well. This feature is
extremely useful during maintenance and troubleshooting procedures.
DHW – Double Hardware Width: Nexto Series modules were designed to save space in user cabinets or machines. For this
reason, Nexto Series delivers two different module widths: Double Width (two backplane rack slots are required) and Single
Width (only one backplane rack slot is required). This concept allows the use of compact I/O modules with a high-density of I/O
points along with complex modules, like CPUs, fieldbus masters and power supply modules.
iF Product Design Award 2012: Nexto Series was the winner of iF Product Design Award 2012 in
industry + skilled trades group. This award is recognized internationally as a seal of quality and
excellence, considered the Oscars of the design in Europe.

Notes:
NET 1: Ethernet interface cannot be used for programming and debugging Nexto Series CPUs.
Gratuitous ARP: NET1 Ethernet interface sends spontaneously ARP type packets in broadcast, informing its IP and MAC
address for all devices interconnected to the network. These packets are sent during the download of a new application by the
MasterTool IEC XE software and in the startup of a NX5000 interface. 5 ARP commands are sent, with an initial interval of 200
ms, doubling the interval between every new triggered command, totalizing 3 s. Example: First trigger occurs at time 0, the
second one at 200 ms, the third one at 600 ms and so forth until the fifth trigger occurs at time 3 s.

Maintenance
Altus recommends that all modules’ connections be checked and that all dust or any kind of dirt at the module’s enclosure be
removed at least every 6 months.
NX5000 offers five important features to assist the user during maintenance: Electronic Tag on Display, One Touch Diag,
Status and diagnostics indicators, web page with complete status and diagnostics list and status and diagnostics mapped to
internal memory.
Electronic Tag on Display and One Touch Diag
Electronic Tag on Display and One Touch Diag are important features that provides for the user the option to check the tag,
description and diagnostics related to a given module directly on the CPU display.
To check the tag and diagnostics of a given module, it’s required only one short press on its diagnostic switch. After pressing
once, CPU will start to scroll tag information and diagnostic information of the module. To access the respective description for
the module, just long press the diagnostic switch of the respective module.
More information about Electronic Tag on Display can be found at Nexto CPU User Manual – MU214605.
Status/Diagnostic Indications
All Nexto slave modules have a display with the following symbols: D, E, 0, 1 and numeral characters. The states of the
symbols D, E, 0, 1 are common for all Nexto series slave modules, these states can be consulted in the table below.
The meaning of the numeral characters can be different for specific modules.

Web Page with Complete Status and Diagnostic List
Another way to access diagnostic information on Nexto Series is via web pages. Nexto Series CPUs have an embedded web
pages server that provides all Nexto status and diagnostic information, which can be accessed using a simple browser.
More information about web page with complete status and diagnostic list can be found at Nexto Series CPUs’ User Manual –
MU214605.
Status and Diagnostics Mapped to Variables
All NX4010’s diagnostics can be accessed through variables that can be handled by the user application or even forwarded to a
supervisory system using a communication channel. There are two different ways to access diagnostics in the user application:
using symbolic variables with AT directive or addressing memory. Altus recommends use symbolic variables for diagnostic
accessing. The table below shows all available diagnostics for NX4010 and their respective memory address, description,
symbolic variable and string that will be shown on the CPU graphical display and web.

Notes:
Direct Representation Variable: “n” is the address defined in the field %Q Start Address of Diagnostic Area on the NX5000’s
configuration screen – Modules Parameters tab in the MasterTool IEC XE.
Symbolic Variable: Some symbolic variables serve to accessing diagnostics. This diagnostics are stored into the addressing
memory, then the AT directive is used to map the symbolic variables in the addressing memory. The directive AT is a reserved
word in the MasterTool IEC XE that uses this directive to declares the diagnostics automatically on a symbolic variables. All
symbolic variables declared automatically can be found inside of Diagnostics object.
