SD1600 Module selection
(base unit No.)
Base unit No. where
the online change
target module is
mounted
The base unit number where the online change target module is
mounted is specified.
0: Main base unit
1: Extension base unit 1

7: Extension base unit 7
FFFFH: Not specified (Default)
The stored value returns to its default (FFFFH) upon completion of
the online module change processing. When changing a module
directly, the system stores the corresponding base unit number
upon removal of the target module.

SD1601 Module selection (slot
No.)
Slot No. where the
online change target
module is mounted
The slot number where the online change target module is
mounted is specified.
0: Slot No.0
1: Slot No.1

11: Slot No.11
FFFFH: Not specified (Default)
The specified value returns to its default (FFFFH) upon completion
of the online module change processing. When changing a module
directly, the system stores the corresponding slot number upon
removal of the target module.

SD1602 I/O No. of the module
being changed online
I/O No. of the module
being changed online
The value of the I/O number of the module being changed online
divided by 16 is stored.
Other than FFFFH: I/O No.  16
FFFFH: Not specified (Default)
The stored value returns to its default (FFFFH) upon completion of
the online module change processing.

3: Module removal requested
4: Module removal ready
5: Module removed
6: Module mounted
7: Module being recognized
8: Module recognized

SD1618 Online module
change error code
0: Normal operation
Other than 0: Error
code
The corresponding error code is stored when an error is detected
during online module change. For the value stored, refer to the list
of error codes. ( Page 786 Error codes related to the online
module change function) This register is cleared to 0 when the
error cause is eliminated and the online module change related
request is executed. However, the error code needs to be cleared
to 0 before module selection since this register is not cleared to 0 if
an error occurs in selecting a module.

SD1619 Disable request error
code during online
module change
0: Normal operation
Other than 0: Error
code
The corresponding error code is stored when a disable request is
executed during online module change. The error code is cleared
to 0 when the error cause is eliminated and the online module
change related request is executed.
For the value stored, refer to the list of error codes. ( Page 786
