NT11S Status Control
Section 5-4
The NT11S functions that can be controlled from the PC are listed below:
Whether the screen is displayed or not
Whether display histories are printed or not
Whether daily reports are printed or not
Since the PT status control bits remain unaffected even if the NT11S status
changes in accordance with the screen attribute and memory switch settings, it
can happen that the status indicated by the PT status control bits does not agree
with the actual status of the NT11S. For example, the screen may be off although
the screen display setting is “ON”. In situations like this, control the NT11S by us-
ing the PT status control bits.
S
Screen display (bit 15)
The screen display bit determines whether the backlight is lit or unlit (whether the
screen is displayed or not). It is used to prolong the service life of the backlight
and prevent the formation of an afterimage. When bit 15 is set to OFF (0), the
backlight is switched off.
Once the screen has been switched off, it can be switched back on either by
switching bit 15 ON (setting it to “1”) or by pressing an NT11s key; this will cause
the backlight to come back on.
- Instead of switching bit 15 ON, a screen number can be specified to switch to
that screen, in which case the screen will be displayed. For details on screen
switching, refer to “Switching the Screen Display” (page 101).
- By setting an NT11S memory switch, it is possible to make the backlight go off
automatically after no operations have been performed for a set length of time.
S
Display history print (bit 5)
”Display history printing” designates printing of the display history data recorded
in the NT11S at a printer. When bit 5 is set ON (set to “1”), all the recorded display
history data is printed out once. To print it out a second time, bit 5 must be
switched OFF (set to “0”) and then switched back ON (to “1”).
For details on the data recorded in the display history and the printing format, refer
to 4-10 Daily Report/Display History Printing Function” (page 91).
S
Daily report print (bit 4)
“Daily report print” designates printing of the contents of PC words and set char-
acters in accordance with a format set using the support tool.
When bit 4 is switched ON (set to “1”), the contents of the specified words are
read from the PC and output to the printer once in the specified format.
To output the data to the printer again, bit 4 must be switched OFF (set to “0”) and
then switched back ON (to “1”).
Settings such as the printing format and word settings are made by using the sup-
port tool. For details on the support tool setting procedures relating to the daily
report printing function, refer to 4-10 “Daily Report/Display History Printing Func-
tion” (page 91).
