Meaning
• This relay turns on when the battery voltage
OFF : Normal drops to or below the specified.
ON : Battery low • It turns off when the battery voltage returns to
normal.
• This relay turns on when the battery voltage
OFF : Normal drops to or below the specified.
ON : Battery low • This relay remains on even after the battery
voltage returns to normal.
OFF : No error This relay turns on if an error is detected by self-
ON : Error diagnostics.
OFF : No F number • This relay turns on when the OUT F or SET F
detected instruction is executed.
ON : F number • It turns off when the SD1124 value is cleared
detected to zero.
• This relay turns on when an operation error
occurs during execution of an application
OFF : No error
instruction.
ON : Error
• This relay remains on even after the system
returns to normal.
OFF : Carry OFF
Carry flag used in application instruction.
ON : Carry ON
When SM1016 turns on and remote RUN mode
OFF : lgnored is activated from a computer, all the data
ON : Output claered memory including the latch range (except for the
special relay and special register) is cleared.
When SM1017 turns on and remote RUN mode
OFF : lgnored is activated from a computer, all the data
ON : Output claered memory that is not latched (except for the
special relay and special register) is cleared.
• This relay repeatedly turns on and off at the
specified scan intervals.
• When the CPU module is powered on or
reset, this relay is set to on from off to start the
clock. Set the intervals of on/off by DUTY
instruction.
•n1: On scan interval
n2 scan n2 scan
•n2: Off scan interval
n1 scan
When SM1020 to SM1024 are specified for
the DUTY instruction in programs, if the CPU
type is changed from the High Performance
model QCPU or Process CPU to the Universal
model QCPU or LCPU, they are replaced with
SM420 to SM424. (For the Universal model
QCPU and LCPU, SM1020 to SM1024 cannot
be specified.)
Clock data stored in SD1025 to SD1028 are
OFF : Ignored
written to the CPU module after the END
ON : Set request
instruction execution in the scan where SM1025
present used
is turned on.
This relay turns on if an error occurs in the clock
OFF : No error
data (SD1025 to SD1028), and is off while there
ON : Error
is no error.
This relay is turned on to read clock data and
OFF : Ignored
store them as BCD values into SD1025 to
ON : Read request
SD1028.
