Details
The number of CPU modules which constitute a multiple CPU system is
stored (one to four, including those reserved).
The number of this CPU No. is stored when a multiple CPU system is
configured.
The operation information for each CPU No. is stored (the amount of
stored information depending on the number of CPU modules indicated
in SD228 is stored).

Mounting status
0: Not mounted

The maximum number of implemented extension base units is stored.
Identify whether or not Q series module can be mounted. When no SD
memory card is inserted, the value is fixed to 0.

The number of slots of the base unit, which is specified in the Base/
power supply /extension cable setting of system parameters, is stored.
When the number of slots of the base unit is not specified by the system
parameter, that of the mounted base unit is stored.

The most significant two digits of the value obtained by adding one to the
latest I/O number for an implemented unit are stored as a BIN value.
The number of points of the device X currently set is stored as 32-bit
data.
The number of points of the device Y currently set is stored as 32-bit
data.
• The number of points of the device M currently set is stored as 32-bit
data.
• The number of points assigned is stored even when the number of
points assigned to M is 32K points or less.
• The number of points of the device B currently set is stored as 32-bit
data.
• The number of points assigned is stored even when the number of
points assigned to B is 32K points or less.
The number of points of the device F currently set is stored as 32-bit
data.
