Details
• The lowest number of module in which a fuse blew is stored.
• The fuse blown state check is also done for output modules on
the remote I/O station.
• In a redundant system with redundant extension base unit, this
register is set as follows:
 If a fuse blown is detected in an output module on an extension
base unit, the I/O number is stored only in the CPU module of
the control system, but not stored in the CPU module of the
standby system.
 When the systems are switched, the state before system
switching is held.
 When the error is cleared, the CPU module of the system
where the error is cleared clears the value.
• The lowest I/O number of the module which has an error detected
by the I/O module verification is stored.
• I/O module verification is also done for modules on the remote I/O
station.
• In a redundant system with redundant extension base unit, this
register is set as follows:
 If an I/O verification error is detected in a module on an
extension base unit, the I/O number is stored only in the CPU
module of the control system, but not stored in the CPU module
of the standby system.
 When the systems are switched, the state before system
switching is held.
 When the error is cleared, the CPU module of the system
where the error is cleared clears the value.
The annunciator number which is detected first is stored.
The number of detected annunciator is stored.
• Numbers of activated annunciators are sequentially registered
into SD64 to SD79, each time an annunciator (F) is turned on by
the SET F instruction.
• Number of the annunciator deactivated by the RST F instruction
is removed from register areas SD64 to SD79, and the numbers
of annunciators which were lined up behind the removed one
move forward one by one. When the number of detected
annunciators has already reached 16, the number of a newly
detected annunciator is not stored into SD64 to SD79.
For details on the annunciator, refer to the annunciator (F) (
