encountered BINHA, DBINHA, BCDDA, DBCDDA, or
COMRD instruction
output
• Designates method to be used by search
instruction.
• Data must be arranged for 2-part search.
The sort instruction is used to designate
whether data should be sorted in ascending
order order or in descending order.
This relay turns on when all data conditions
are met for the BKCMP instruction.
This relay turns on when all data conditions
are met for the DBKCMP instruction.
This relay turns on when the data to be
compared by the DT or TM instruction cannot
not detected
be recognized as date or time data, when the
device (three words) to be compared is
detected
exceeding the specified device range.
• Remains as originally set when OFF.
priority • Priority for the CHK instruction is changed
when on.
This relay is on while the EI instruction is
being executed.
This relay turns on when all data conditions
are met for the DBKCMP instruction. (Initial
execution type program and scan execution
type program or standby type program
executed from initial execution type program
or scan execution type program)
This relay turns on when all data conditions
are met for the DBKCMP instruction.
(Interrupt program, fixed scan execution type
program, or standby type program executed
from interrupt program or fixed scan
execution type program)
This relay turns on when all data conditions
are met for the DBKCMP instruction.
(Interrupt program (I45) or standby type
program that was executed from interrupt
program (I45))
This relay turns on only during first scan after
the processing of the COMRD or PRC
instruction is completed.
not completed
This relay turns on only during first scan after
completed
the processing of the COMRD instruction is
completed.
