Fuse blown
module
Bit pattern in units of 16 points,
indicating the modules whose
fuses have blown.
!
Output module numbers of the (in units of 16 points) of output modules whose
fuses have blown or whose external power supply has been switched OFF are
entered in a bit pattern.
(Preset output number when parameter setting bas been performed).

Input/Output
module
verification error
Bit pattern, in units of 16 points,
indicating the modules with
verification errors.
!
When an I/O modules whose data is different from that entered are detected, the
I/O module numbers (in units of 16 points) are entered in a bit pattern.
(Preset I/O module numbers when parameter setting has been performed.)

D9124
Annunciator
detection
quantity
Number of detected annunciators
!
When one of F0 to 255 is turned on by an OUT F or SET F , 1 is added to the
contents of D9124.
When the RST F or LED R instruction is executed, 1 is subtracted from the
contents of D9124.
The number of annunciators that has been turned on by OUT F or SET F is
stored in D9124: the maximum stored value is 8.
D9125

D9132
Annunciator
detection
number
Annunciator detection number
!
When F numbers in the range F0 to 255 are turned on by OUT F or SET F ,
they
are entered in D9125 to D9132 in ascending order of register numbers.
An F number which is turned off by RST F is erased from D9125 to D9132, and
the contents of the data registers following the one where the erased F number
was stored are each shifted to the preceding data register. When the LEDR
instruction is executed, the contents of D9125 to D9132 are shifted upward by
one. When there are 8 annunciator detections, a 9th one is not stored in D9125 to
D9132 even if detected.
