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
Runs or stops the program operations in
the CPU module externally.
Section 6.6.1
Remote PAUSE
Stops the program operations in the CPU
module externally, holding the status of
outputs (Y).
Section 6.6.2
Remote RESET
Resets the CPU module externally 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
H/W error time PLC
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.
