present
• 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.
Example: 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 storage value is cleared by clearing the error.

verification
error
Bit pattern, in
units of 16
points,
indicating the
modules with
verify errors.
0: No error
1: Error
• If the status of the I/O module changes from that obtained
at power-on, the module No. is stored in the following bit
pattern. (If the I/O numbers are set by parameter, the
parameter-set numbers are stored.)
• The status of the I/O module on a remote station is also
detected.
For a module whose number of I/O points exceeds 16 points,
all bits corresponding to I/O module numbers within the
number of I/O 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 an error is detected.
• Not cleared even if the blown fuse is replaced with a new
one. This flag is cleared by error resetting operation.
