Note that if the screen is OFF by the backlight OFF or EL screen OFF func-
tion with Bit 15 ON (1), turn Bit 15 OFF (0) once and then turn it back ON
(1) to redisplay the screen.

• Priority Registration for Processing (1:N NT Link Only) (Bit 14)
It is possible to register one of the multiple PTs connected by the 1:N NT
link method to have processing priority. The PT for which bit 14 is set ON
(1) is given priority over the other PTs and has a higher response speed
for display, touch switches, etc.
When bit 14 is turned OFF (0), this registration is canceled and the normal
response speed is reinstated. If priority registration is set for more than one
PT, the one for which the registration was made last will have priority.
By monitoring C200HX/HG/HE words, the unit number of the PT for which
priority registration has been set can be confirmed. For details on the mon-
itoring operation at the PLC, refer to the manual for the PLC used.
