Small Size, Large Screen
The LCD screen is larger than the OMRON NT20S
(increased from 256 x 128 dots to 260 x 140 dots), but the
external dimensions and panel cut-out size are the same.

Two RS-232C Ports
Two RS-232C ports in the NT21 (compared with one in the
NT20S) enable simultaneous connection of a PLC, Bar
Code Reader, and NT Support Tool (connectable to serial
port A only).

Plenty of Capacity for Saving Graphic Screens
With 512 Kbytes of memory
capacity, there is more than
ample space for storing screen
data.

Versatile Communications
In addition to the Host Link and 1:1 NT Link
communications, the NT21 supports high-speed 1:N NT
Links and Memory Link communications.

Conforms to International Standards
The NT21 conforms to the EC Directives, as well as UL,
cULus (Class 1 Div2), and C-Tick.
The front panel has an enclosure rating equivalent to IP65F.
System and screen data can be stored in
NT21 Flash Memory.

Recipe Function
Parts tables on the PT
screen can be used to set
NT21
multiple word data in
records, which can then
be written to the PLC by a
simple PT touch panel operation. For example, the setting
parameters for separate models can be edited on the PT,
then written to or read from the PLC.
Alarm List/History(*)
An alarm message can be
displayed in response to
PLC bit status, and the
content and time of the
message can be stored as

Programming Console Function
The NT21 is equipped with many of the same functions as
the SYSMAC PLC Programming Console.

Mathematical Functions
Up to 256 math equations can be stored in the PT
Personal
processing table to allow automatic PT processing, and
computer
the results can be written to the numeral memory table or

other destinations. This makes it possible to perform
scaling and other mathematical operations automatically
in the PT.

Enhanced Editing Functions
•I/O comments in the I/O tables of the CX-Programmer can
be used directly.
I/O comments for designated PLC addresses can be
used directly, with no need for CSV file conversion.

•Parts can be copied by drag &

•The properties of grouped
parts can be edited without
having to ungroup them.
•Because NT20S and NT31
screen data is compatible
with the NT21, existing software assets can be utilized
to greatly reduce the number of design steps.
Note: Some data revisions may be required due to size differences.
