In order to access the NT30/30C status from the PC, PT status in the PT status
notification area is used.
The status (operating statuses, etc.) of the NT30/30C can be determined from
the PC by reading the PT status word in the PT Status Notify Area allocated in the
PC memory.
PT Status Notification Bits in the PT Status Notify Area
S PT Operating Status (Bit 15)
S Battery (Bit 13)
S Screen Switch Strobe Flag (Bit 12)
When the NT30/30C is in the RUN mode this bit is set to ON (1). In other modes
and while the system menu is displayed it is OFF (0). When this bit is OFF allo-
cated bits and words cannot be read or written to.
If the voltage of the backup battery for the NT30/30C memory becomes low,
this bit is set to ON (1).
When the screen displayed on the NT30/30C is switched by a designation from
the PC, by the stand-alone function or by the operation of the allocated bit of a
bit memory table entry, the screen switch strobe flag comes ON (1). On notifi-
cation to the PC, it returns to the OFF (0) status.
For details on how the screen switch strobe flag is used, see Notifying the PC of
the Display Screen (page 199).
