Automação S.A. who reserves the right to carry out alterations without prior advice.
According to current legislation in Brazil, the Consumer Defense Code, we are giving the following information to clients
who use our products, regarding personal safety and premises.
The industrial automation equipment, manufactured by Altus, is strong and reliable due to the stringent quality control
it is subjected to. However, any electronic industrial control equipment (programmable controllers, numerical commands,
etc.) can damage machines or processes controlled by them when there are defective components and/or when a programming
or installation error occurs. This can even put human lives at risk. The user should consider the possible consequences of
the defects and should provide additional external installations for safety reasons. This concern is higher when in initial
commissioning and testing.
The equipment manufactured by Altus does not directly expose the environment to hazards, since they do not issue any kind
of pollutant during their use. However, concerning the disposal of equipment, it is important to point out that built-in electronics
may contain materials which are harmful to nature when improperly discarded. Therefore, it is recommended that whenever
discarding this type of product, it should be forwarded to recycling plants, which guarantee proper waste management.
It is essential to read and understand the product documentation, such as manuals and technical characteristics before its
installation or use. The examples and figures presented in this document are solely for illustrative purposes. Due to possible
upgrades and improvements that the products may present, Altus assumes no responsibility for the use of these examples and
figures in real applications. They should only be used to assist user trainings and improve experience with the products and
their features.
Altus warrants its equipment as described in General Conditions of Supply, attached to the commercial proposals.
Altus guarantees that their equipment works in accordance with the clear instructions contained in their manuals and/or
technical characteristics, not guaranteeing the success of any particular type of application of the equipment.
Altus does not acknowledge any other guarantee, directly or implied, mainly when end customers are dealing with third-
party suppliers. The requests for additional information about the supply, equipment features and/or any other Altus services
must be made in writing form. Altus is not responsible for supplying information about its equipment without formal request.

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.

1.2. Innovative Features
Nexto Series brings to the user many innovations regarding utilization, supervision and system maintenance. These features
were developed focusing a new concept in industrial automation.
VPN: Nexto products have an embedded VPN service, which creates a private tunnel that connects
directly to the CPU. This functionality, available on some models of the family, allows accessing a
control network remotely and completely securely..
FTP: Supporting FTP-type connections, the series equipment is able to exchange data with a server
that uses this same technology model. This functionality allows the files generated by the controller,
such as logs collected through a datalogger function, to be accessed remotely.
Linux: Another innovative feature of the series is its embedded Linux platform. The feature makes
possible the virtualization of software developed for operating systems with Unix technology. The
feature gives more versatility and speed to the operation of the system, as it allows the processing of
multiple data within the CPU itself.
Battery Free Operation: Nexto Series does not require any kind of battery for memory maintenance
and real time clock operation. This feature is extremely important because it reduces the system
maintenance needs and allows the use in remote locations where maintenance can be difficult to be
performed. Besides, this feature is environmentally friendly.
Easy Plug System: Nexto Series has an exclusive method to plug and unplug I/O terminal blocks.
The terminal blocks can be easily removed with a single movement and with no special tools. In order
to plug the terminal block back to the module, the frontal cover assists the installation procedure,
fitting the terminal block to the module.
Multiple Block Storage: Several kinds of memories are available to the user in Nexto Series CPUs,
offering the best option for any user needs. These memories are divided in volatile memories and
non-volatile memories. For volatile memories, Nexto Series CPUs offer addressable input (%I),
addressable output (%Q), addressable memory (%M), data memory and redundant data memory.
For applications that require non-volatile functionality, Nexto Series CPUs bring retain addressable
memory (%Q), retain data memory, persistent addressable memory (%Q), persistent data memory,
program memory, source code memory, CPU file system (doc, PDF, data) and memory card interface.
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), re-
ducing maintenance and commissioning times.

1. INTRODUCTION
OFD – On Board Full Documentation: Nexto Series CPUs are capable of storing the complete
project documentation in its own memory. This feature can be very convenient for backup purposes
and maintenance, since the complete information is stored in a single and reliable place.
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 cabi-
nets 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.
High-speed CPU: All Nexto Series CPUs were designed to provide an outstanding performance to
the user, allowing the coverage of a large range of applications requirements.

Notes:
Addressable input variables memory (%I): Area where the addressable input variables are stored. Addressable variables
means that the variables can be accessed directly using the desired address. For instance: %IB0, %IW100. Addressable input
variables can be used for mapping digital or analog input points. As reference, 8 digital inputs can be represented per byte and
one analog input point can be represented per two bytes.
Total addressable output variables memory (%Q): Area where the addressable output variables are stored. Address-
able variables means that the variables can be accessed directly using the desired address. For instance: %QB0, %QW100.
Addressable output variables can be used for mapping digital or analog output points. As reference, 8 digital outputs can be
represented per byte and one analog output point can be represented per two bytes. The addressable output variables can be
configured as retain, persistent or redundant variables, but the total size is not modified due to configuration.
Addressable variables memory (%M): Area where the addressable marker variables are stored. Addressable variables
means that the variables can be accessed directly using the desired address. For instance: %MB0, %MW100.
Symbolic variables memory: Area where the symbolic variables are allocated. Symbolic variables are IEC variables
created in POUs and GVLs during application development, which are not addressed directly in memory. Symbolic variables
can be defined as retentive or persistent, in which case the memory areas of retentive symbolic variables or memory of persistent
symbolic variables respectively will be used. The PLC system allocates variables in this area, so the space available for the
allocation of variables created by the user is lower than that reported in the table. The occupation of the system variables
depends on the characteristics of the project (number of modules, drivers, etc...), so it is recommended to observe the space
available in the compilation messages of the MasterTool IEC XE tool.
Persistent or Retain symbolic variables memory: Area where are allocated the retentive symbolic variables. The re-
tentive data keep its respective values even after a CPU’s cycle of power down and power up. The persistent data keep its
respective values even after the download of a new application in the CPU.
ATTENTION
The declaration and use of symbolic persistent variables should be performed exclusively
through the Persistent Vars object, which may be included in the project through the tree
view in Application -> Add Object -> Persistent Variables. It should not be used to VAR
PERSISTENT expression in the declaration of field variables of POUs.
The full list of when the symbolic persistent variables keep their values and when the value is lost can be found in the table
below. Besides the persistent area size declared in the table above, are reserved these 44 bytes to store information about the
persistent variables (not available for use).
The table below shows the behavior of retentive and persistent variables for different situations in which “-“ means the
value is lost and “X” means the value is kept.
