video. High grade fonts are available for the characters with their size enlarged.
Graphic display
Polylines, rectangles, polygons, circles, circular arcs, and sector shapes can be displayed. They can
also be tiled with various patterns, flashed, or displayed in reverse video.
Memory data display
The contents of character string memory tables and numeral memory tables can be displayed. The
contents of memory tables can be changed from the host.
Graph display
Not only bar graphs but also broken line graphs, trend graphs, and analogue meter graphs can be
displayed using numeral memory tables
Lamp display
Lamps can be turned on and flashed under the control of the host. It is also possible to display different
graphics in the ON and OFF states.
Alarm list/history display
Warning messages are automatically displayed in a list in response to the state of a host bit. The time
and the number of times of the messages appeared can also be displayed.
Functions relating to data output
Buzzer
A built-in buzzer can be sounded.
Screen printing
A hard copy of the currently displayed screen can be printed at the printerconnected to the NT31/NT31C.
