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 Nexto Series.
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.
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), reducing maintenance and commissioning times.
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
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, such as 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. For example: Nexto
CPUs NX3010, NX3020 and NX3030 can execute a sum, multiplication and subtraction instruction
in less than 15 ns for integer type values and in less than 23 ns for real type values. Nexto CPUs are
able to perform 1,000 PID loops in less than 5 ms.
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.
