Processing Priority Registration (For NT Link 1:N) (Bit 14)
One of the PTs connected by the NT link (1:N) method can be registered for
priority processing. The PT for which bit 14 is set to ON (1) is given priority over
the other PTs, and has more rapid response time for screen display, touch switch
operations, etc.
When bit 14 is set to OFF (0), this registration is canceled and the response
speed is returned to normal. If priority registration is set for more than one PT, the
one set last is given priority.
The unit number of the PT given priority registration can be checked by monitor-
ing (reading) a word at the CS1G/CS1H, C200HX/HG/HE(-Z)E, CQM1H, and
SRM1. For details on the word monitoring operation at a PC, refer to the manual
for the PC you are using.
The contents of the words that reflect the status of an NT link (1:N) system are
indicated below.

Continuous Buzzer (Bit 13), Short Intermittent Buzzer (Bit 12), Long Inter-
mittent Buzzer (Bit 9)
The continuous buzzer continues buzzing with no interruptions.
The short intermittent buzzer repeatedly alternates between sounding for 0.5
seconds and stopping for 0.5 seconds.
The long intermittent buzzer repeatedly alternates between sounding for 1.0 se-
conds and stopping for 1.0 seconds.
