Details
• This relay turns on when the battery voltage drops
to or below the specified.
• It turns off when the battery voltage returns to
normal.
• This relay turns on when the battery voltage drops
to or below the specified.
• This relay remains on even after the battery
voltage returns to normal.
This relay turns on if an error is detected by self-
diagnostics.
• This relay turns on when the OUT F or SET F
instruction is executed.
• It turns off when the SD1124 value is cleared to
zero.
• This relay turns on when an operation error occurs
during execution of an application instruction.
• This relay remains on even after the system
returns to normal.
Carry flag used in application instruction.
When SM1016 turns on and remote RUN mode is
activated from a computer, all the data memory
including the latch range (except for the special relay
and special register) is cleared.
When SM1017 turns on and remote RUN mode is
activated from a computer, all the data 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.
DUTY n1 n2 SM1020
•n1: On scan interval
•n2: Off scan interval
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 written
to the CPU module after the END instruction
execution in the scan where SM1025 is turned on.
This relay turns on if an error occurs in the clock data
(SD1025 to SD1028), and is off while there is no
error.
This relay is turned on to read clock data and store
them as BCD values into SD1025 to SD1028.
• When this relay is turned on in the program, all the
data communication requests accepted during one
scan are processed in the END processing of that
scan.
• The batch processing of data communication
requests can be turned on or off during running.
• The default is OFF (processed one at a time for
each END processing in the order in which data
communication requests are accepted).
