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.
