Improved SYSMAC Compatibility for
Easier System Construction
Programming Console and Device Monitor Functions
Registration
monitor
[Device Monitor]
The device monitor function makes it possible to read and
write I/O memory data and display consecutive sections of
PLC data areas. This function greatly improves the efficiency
of PLC setup work, including set value input into the Special
I/O Units and checks on the settings. Data can be read from
I/O memory from a user-created screen to enable application
on maintenance screens for monitoring.

PT
[Programming Console Functions]
C-series and CS/CJ-series ladder programs can be written

I/O Comments Can Now Be Imported
I/O comments can now be imported from ladder program
files, such as CX-Programmer files. Imported I/O comments
can be used as labels to eliminate the bother of entering
comments. This also prevents I/O allocation mistakes between the PT and PLC, and reduces the time required to correct such mistakes.

The industry's highest serial communications speed.
Up to eight NT631/NT31/NT20 Units can be connected to a
single port.
Extends to a maximum of 500 m.
Essentially the same performance is achieved for NT Links with
eight PTs as for an NT Link with a single PT (for refreshing
numeric displays).

The Backlight Module has been redesigned to eliminate the need to replace the Backlight and enable
maintenance-free operation for up to 50,000 hours.
System Program Transfer
By transferring a new system program, functions
and performance can be updated without changing
hardware.
The following system programs are provided.
OMRON (Memory Link) and Mitsubishi versions
for NT31/631

1) The compatible combinations of NT31/631 models
and system program versions are shown in the
table.
: Indicates the preinstalled default combination of
versions (recommended).
: Indicates combinations of versions that can be
transferred for operation.
: Indicates combinations of versions that can be
transferred but for which some functions are
restricted during operation (e.g., high-quality
character display).
: Indicates combinations of versions that cannot be
transferred.
2) NT31/631 system program version 4.x can be
transferred only with System Installer V2, which is
available on the CD for NT Series Support
Software version 4.08 or higher. Only system
programs up to version 3.x can be transferred with
older versions of the System Installer.
3) The NT20 system program can be transferred
only with System Installer V2.1, which is available
on the CD for NT Series Support Software version
4.8 or higher. It cannot be transferred with lower
versions of the System Installer.

Special Utility to Transfer Screen Data
It is possible for anyone to easily transfer screens
by using a special software application instead of
the NT Support Software. The software application
can be set up separately.
The NT20 system program can be transferred
using the transfer utility provided with NT Support
Software version 4.8 or higher. Change the setting
to "NT20S" if using the transfer utility provided with
Support Software version 4.0 or lower.
Supports Wide Variety of Language Input
European and English languages are supported. (The English version of the NT Support Software is used.)
Furthermore, Simplified and Traditional Chinese are supported. (The NT Support Software uses
specifications for all languages.) Contact your OMRON sales representative for details.
Note: Traditional Chinese is supported only by NT31/631.
Memory Unit for Easy and Immediate Screen Data Transfer
Simply attach the Memory Unit to the back of the
NT631/NT31/NT20 to easily transfer screens. Up
to two banks can be registered and both system
programs and screen data can be transferred.
Check Screen Data without Programmable Controller
The NT631/NT31 displays screens, such as lamps, touch switches,
and memory table numbers, without the PLC connected, to enable efficient debugging.
