Fuse blown
module
Bit pattern in units
of 16 points,
indicating the
modules whose
fuses have blown
• The number of an output module whose fuse has blown
is stored in the following bit pattern (in units of 16 points).
(If the module numbers are set by parameter, the
parameter-set numbers are stored.)
For a module whose number of output points exceeds 16
points, all bits corresponding to output module numbers
within the number of output points occupied by the module
(in increments of 16 points) turn on.
Example: When a 64-point module is mounted on the slot 0,
b0 to b3 turn on when the fuse has blown.
• Output modules on remote I/O stations are also checked
for blown fuse. (This register must be cleared by a
program because the bit status remains unchanged even
after clearing the error.)

and the F number
at time out
• This register stores a value set for step transition
monitoring timer and the number of an annunciator (F
number) that turns on if the monitoring timer times out.
• Turning on any of registers SM1108 to SM1114 activates
a monitoring timer. If the transition condition for the step
is not established before the time-out time, the
annunciator (F) turns on.
