• 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.)
• The status of the blown fuse of an output module on a remote station is
also detected.
• 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 units of 16 points) turn on.
When a 64-point module is mounted on the slot 0, b0 to b3 turn on
when the fuse has blown.
• Not cleared even if the blown fuse is replaced with a new one.
The numbers are cleared by clearing the error.
• The module No. is not cleared even when the output module goes back to
normal.
The number is cleared by clearing the error.
