5)
Constant scan
Executes the program in a set time interval
regardless of the program scan time.
Latch function
Retains the device data even at power OFF or reset.
Output status selection when the
status changed from STOP to RUN
Selects the output (Y) status (outputting the same
status prior to STOP or clearing the status) when the
CPU module status is switched from STOP to RUN.
Clock function
Reads the internal clock data of the CPU module to
use it for time management.
Remote RUN/STOP
Stops or executes operations in the CPU module.
Remote PAUSE
Stops operations in the CPU module while retaining
the status of output (Y).
Remote RESET
Resets the CPU module when the CPU module is in
a STOP status.
Remote latch clear
Clears the latch data of the CPU module when the
CPU module is in a STOP status.
Input response time selection
Selects the input response time for the Q series
compatible input modules, I/O combined modules,
high-speed input modules, and interrupt modules.
