Explanation
• The number of base unit slots set in parameter is stored.
When the number is not set in parameter, the number of
base unit slots used is stored.

• For the Q00UJCPU, the bits for the third to seventh
extension bases are fixed to "0".
• For the Q00UCPU, Q01UCPU, and Q02UCPU, the bits for
the fifth to seventh extension bases are fixed to "0".
The number of slots used is stored in the area corresponding
to each base unit as shown below. (The number of slots set in
the parameter setting.)
b15 to b12 b11 to b8 b7 to b4 b3 to b0

The number of slots where modules are actually mounted is
stored in the area corresponding to each base unit as shown
below.

When SM250 is turned on from off, the first two digits of the
number, which is the last I/O number of the mounted modules
plus 1, are stored.
The value obtained by adding 1 to the end I/O number of a
mounted module and dividing by 16 is stored.
Example 1:End I/O number 010F SD250 = 0011
Example 2:End I/O number 0FFF SD250 = 0100
Indicates the number of mounted MELSECNET/10 modules or
MELSECNET/H modules.
Indicates the I/O number of mounted MELSECNET/10 module
or MELSECNET/H module.
Indicates the network No. of mounted MELSECNET/10
module or MELSECNET/H module.
Indicates the group No. of mounted MELSECNET/10 module
or MELSECNET/H module.
Indicates the station No. of mounted MELSECNET/10 module
or MELSECNET/H module.
In the case of standby stations, the module number of the
standby station is stored. (1 to 4)
Data configuration is the same as that of the 1st module
(SD255 to SD259).
Data configuration is the same as that of the 1st module
(SD255 to SD259).
