blown fuse
• When fuse blown modules are detected, the lowest I/O module No. is stored
in D9000.
D9005
AC/DC DOWN
counter No.
Number of times
for AC/DC DOWN
• 1 is added to the stored value each time the input voltage becomes 85[%]
(AC power supply/65[%] DC power supply) or less of the rating while the
CPU module is performing an operation, and the value is stored in BIN
code.
