Screen data can be checked simply by operations at the NT31/NT31C system
menu, without connecting up to the Support Tool.
The data capacity of 1 MB is twice that of the NT30/NT30C, enabling storage of a
larger quantity of screen data.
The number of elements that can be registered on one screen has been consid-
erably increased, making it possible to create more expressive screens. For de-
tails, refer to Display Restrictions in Appendix A Specifications of the
NT31/NT31C/NT631/NT631C Programmable Terminal Reference Manual.
It is now possible to write binary data stored in words at the host directly to the
NT31/NT31C. This makes data conversion by a program at the host unneces-
sary, reducing the load on the host.
Any quadrupled characters are displayed with a 32 dot high-definition font.
By using the system installer supplied with the Support Tool (Type NT-
ZJCAT1-EV4), the system program at the NT31/NT31C can be changed easily
from a personal computer.
The NT31/NT31C meets UL/CSA standards and EC directives.
Compatible with Sequencers in the following series: Mitsubishi A-series (Calcu-
lator Link) and FX-series (Programming Console), Allen-Bradley SLC 500 Se-
ries, GE Fanuc 90-20 and 90-30 Series, and Siemens S7-300 and S7-400 Se-
ries. Specialized system programs can be installed that allow the NT31/NT31C
to be controlled from other companies' Sequencers.
Up to 3 windows can be displayed simultaneously in the normal screen. A
9-word window control area has been allocated to the host; the contents of these
9 words can be changed from the Host to open, close, and move windows.
Two NT31 models — the NT31, which is capable of versatile graphic displays,
and the NT31C, which is also capable of color display — are available. The dif-
ferences between the NT31 and NT31C are tabled below:

Beige and black are the front panel colors of each NT31/NT31C types.
The V2 versions of NT31/NT31C are supplemented and enhanced by the fol-
lowing functions.
The V2 versions are compatible with the high-speed 1:N NT Link as well as the
earlier standard 1:N NT Link.
Operands (values referenced by formula) can be registered to allow the PT to
perform calculations automatically and write the results of those calculations to
numeral memory tables or words in the host.
The new device monitor function can be used to change the PLC's operating
mode or display/change values in the PLC's memory areas. The present values
(PVs) of several words can be listed with the device monitor.
