S PT operating status (bit 15)
When the NT620S/620C 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 allocated bits and words cannot be read or written to.
To ensure system safety, be sure to periodically read the PT operating status bit
from the host in order to ensure that the PT is always operating normally.

When the screen displayed on the NT620S/620C 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, the screen switch strobe flag comes ON (1). On notifica-
tion to the PC, it returns to the OFF (0) status.
For details on how the screen switch strobe flag is used, see "Notifying the dis-
play screen to the PC" (page 195).

meral setting function, the numeral setting strobe flag comes ON (1). On notifi-
cation to the PC, it returns to the OFF (0) status.
For details on how the numeral setting strobe flag is used, see "Notification of
