Reference
Constant scan
Executes a program in a set time interval 
regardless of its scan time.
Section 6.2
Latch function
Holds the device data even at power OFF 
or reset.
Section 6.3
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.
Section 6.4
Clock function
Reads the internal clock data of the CPU 
module to use it for time management.
Section 6.5
Remote RUN/STOP
Stops or runs the program operations in 
the CPU module.
Section 6.6.1
Remote PAUSE
Stops the program operations in the CPU 
module, holdng the status of outputs (Y).
Section 6.6.2
Remote RESET
Resets the CPU module when the CPU 
module is in a STOP status.
Section 6.6.3
Remote latch clear
Clears the latch data in the CPU module 
when the CPU module is in a STOP 
status.
Section 6.6.4
Input response time 
selection
Selects input response time values for 
the Q series-compatible input modules, I/
O combined modules, high-speed input 
modules, and interrupt modules.
Section 6.7
Error time output mode 
setting
Sets whether to clear or retain the output 
to the Q series compatible output 
modules, I/O combined modules, 
intelligent function modules, and interrupt 
modules at the time of a stop error of the 
CPU module.
Section 6.8
Hardware error time 
CPU operation mode 
setting
Sets whether to stop or continue 
operations in the CPU module when a 
hardware error has occurred in an 
intelligent function module or interrupt 
module.
