Fuse blown
module
Bit pattern in units
of 16 points,
indicating the
modules whose
fuses have blown
0 : No blown fuse
1 : Blown fuse
present
• The numbers of output modules whose fuses have blown are input as a
bit pattern (in units of 16 points).
(If the module numbers are set by parameter, the parameter-set
numbers are stored.)
• Also detects blown fuse condition at remote station output modules
• Not cleared even if the blown fuse is replaced with a new one.
This flag is cleared by error resetting operation.

errors
1 : I/O verification
error present
• When the I/O modules whose I/O module information differs from that
registered at power-ON are detected, the numbers of those I/O modules
are entered in bit pattern.
(If the I/O numbers are set by parameter, the parameter-set numbers
are stored.)
• Also detects I/O module information.
• Not cleared even if the blown fuse is replaced with a new one.
This flag is cleared by error resetting operation.
