Name
Turns on when a self-diagnosis error occurs. Self-diagnosis error
codes are saved in the system data register SD0.
Turns on when a unit alarm is detected. The slot number of the unit
where an alarm has occurred is saved in the system data register
SD1.
Turns on when a unit error is detected. The slot number of the unit
where an error has occurred is saved in the system data register
SD2.
Turns on when a unit warning is detected. The slot number of the
unit where a warning has occurred is saved in the system data
register SD3.
Turns on when an I/O verification error is detected. The slot number
of the unit where an I/O verification error has occurred is saved in
the system data register SD4.
Turns on when a unit installation error is detected. The slot number
of the unit where an I/O verification error has occurred is saved in
the system data register SD5.
Turns on when an operation error occurs after the unit has started
operating, and remains on while the unit operation continues. The
PB number where an error has occurred is saved in the system
data SD7, 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.
