6-4 NT600S Status Control
The statuses of the NT600S 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.

Note 1: When “Screen display = ON”, the back-
light/EL display is ON and when
“Screen display = OFF”, the backlight/
EL display is OFF.
Note 2: Priority registration is only valid when
NT link (1:N) is set.
Note 3: These functions cannot be used for
NT600S-ST211.
The PC status control bits remain unchanged if the NT600S 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 NT600S. For example,
the buzzer may sound even though the setting for continuous buzzer bit 13 is
“OFF”.
In this kind of case, control the NT600S by using the PT status control bits.
