(4) Fuse blown module
• 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

• Not cleared even if the blown fuse is replaced with a new one.
This flag is cleared by error resetting operation.
The module number (in units of 16 points) whose external power
supply has been disconnected is input as a bit pattern.
(If the module numbers are set by parameter, the parameter-set
numbers are used.)

(5) I/O module verification
• When the power is turned on, the module numbers of the I/O
modules whose information differs from the registered I/O
module information are set in this register (in units of 16 points).
(If the I/O numbers are set by parameter, the parameter-set
numbers are stored.)
• Also detects I/O module information
