NT20S Status Control
Section 5-4
5-4 NT20S Status Control
The statuses of the NT20S can be controlled from the PC by writing control data to
the “PT status control bits” of the PT status control area allocated in the PC
memory.

5-4-1 Controllable NT20S Functions
[“PT status control bits” of the PT status control area]
Item Controlled 1 (ON) 0 (OFF)
Screen display
(Note 1)
ON OFF
Processing priority
registration
(Note 2)
ON OFF
Continuous buzzer ON OFF
Intermittent buzzer ON OFF
Backlight mode ON Flash
Note 1: The backlighting is on when the screen
display bit is set to ON and off when the
screen display bit is set to OFF.
Note 2: Priority registration is only valid when
NT link (1:N) is set.
The PC status control bits remain unchanged if the NT20S status is changed with
the screen attributes or memory switches, which means that the statuses of the
PT status control bits do not match the actual status of the NT20S. For example,
the buzzer may sound even though the setting for continuous buzzer bit 13 is
“OFF”.
In this kind of case, control the NT20S by using the PT status control bits.
