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
OFF : AC/DC DOWN
the CPU module is powered off and then on.
not detected
ON : AC/DC DOWN
This relay turns on if a momentary power
detected
failure within 10ms occurs during use of an AC
power supply module. This relay is reset when
the CPU module is powered off and then on.
OFF : AC/DC DOWN This relay turns on if a momentary power
not detected failure within 10ms occurs during use of a DC
ON : AC/DC DOWN power supply module. This relay is reset when
detected the CPU module is powered off and then on.
• This relay turns on if an operation error
OFF : Normal occurs.

returns to normal.
• Turns on if there is at least one output
module whose fuse has blown.
