Meaning
This relay turns on if a momentary power
failure within 20ms occurs during use of
an AC power supply module. This relay is
reset when the CPU module is powered
off and then on.
This relay turns on if a momentary power
OFF: AC/DC DOWN
failure within 10ms occurs during use of
not detected
an AC power supply module. This relay is
ON: AC/DC DOWN
reset when the CPU module is powered
detected
off and then on.
This relay turns on if a momentary power
failure within 10ms occurs during use of a
DC power supply module. This relay is
reset when the CPU module is powered
off and then on.
• This relay turns on if an operation error
OFF: Normal occurs.
ON: Operation error • This relay remains on even after the
system returns to normal.
• This relay turns on if there is at least
one output module whose fuse has
OFF: Normal blown.
ON: Module with • This relay remains on even after the
blown fuse system returns to normal.
• Output modules on remote I/O stations
are also checked.
• This relay turns on if the status of the
I/O module differs from that registered
at power-on.
OFF: Normal
• This relay remains on even after the
ON: Error
system returns to normal.
• I/O modules on remote I/O stations are
also checked.
OFF: Not detected This relay turns on if at least one
ON: Detected annunciator (F) turns on.
• This relay turns on if an error is
OFF: Not detected detected by the CHK instruction.
ON: Detected • This relay remains on even after the
system returns to normal.
This relay is turned on to clear an error
