● Infrared Communications Use
Select ON or OFF to enable or disable using infrared communications
with the related information setting. The setting can be accepted in both
setup area 0 and setup area 1.
● Setting Areas
Control operation is executed in setting area 0. In this state, you can
perform operations that are permitted only during control or those that
cause no problems even if control is in progress. These operations
include reading PVs, writing SPs, and change RUN/STOP status.
Setting area 0, however, prohibits operations that affect control,
including writing data at the initial setting level. (Reading setting data is
always allowed.)
In setting area 1, control operation is stopped. In this state, you can
perform operations that are not allowed in setting area 0. These opera-
tions include writing data at the initial setting level.
At power-ON, the Digital Controller is set in setting area 0. To move to
setting area 1, use the “move-to-setting area 1” command. To return to
setting area 0, turn the power OFF and ON again, or use the “software
reset” command.
