Description
and the address is saved in system data registers SD8 to SD9. It
indicates the first operation error that has occurred.
Turns on every time an operation error occurs. The PB number where an
operation error has occurred is saved in the system data register SD10,
and the address is saved in system data registers SD11 to SD12. Every
time a new error occurs, the data are updated. It does not turn off even if
the instruction is normally completed after the occurrence of the error(s).
In order to check if any error has occurred in a specific instruction, either
see address data saved in the SD, or clear error flags using ERR
instruction immediately before the specific instruction, and check flags
immediately after executing the instruction.
Used in shift instruction and rotate instruction with a carry flag. The flag
can also be operated in carry set instruction and carry reset instruction. It
is not set in overflow or underflow of operation results.
Turns on when an error occurs during the execution of Ethernet
communication instruction. The error code is stored in the system data
register SD29.
Executes comparison instruction, and turns on if the result is larger.
Executes comparison instruction, and turns on if the result is equal.
Executes operation instruction, and turns on if the result is '0'.
Executes comparison instruction, and turns on if the result is smaller.
Turns on after support timer instruction (SPTM) is executed and
subsequently specified time has passed. Turns off when execution
conditions go off.
Turns on when any of the error alarm relays E0 to E4095 turns on. Turns
off once all of the error alarm relays go off.
Turns on if scan time exceeds the setting during constant scan. It also
turns on if '0' is set in FP7 configuration.
Description
Is normally on.
Is normally off.
Turns on or off in each scan.
Goes on for only the first scan after operation (RUN) has been started,
and goes off for the second and subsequent scans.
Goes off for only the first scan after operation (RUN) has been started,
and goes on for the second and subsequent scans.
Turns on in the first scan only, following startup of any single process,
during stepladder control.
Turns on at the start of execution of a program block. Turns off in the
next scan.
Turns off at the start of execution of a program block. Turns on in the
next scan.
