• Please note that the total of the capacity of each area (including the capacity of the local device area)
should not exceed the capacity of the device/label memory ( Page 74 Hardware specifications). The
total of the capacity of each area can be checked in "Device/Label Memory Area Capacity Setting".
• When the capacity of the file storage area is changed, files (file register files) stored in the area are deleted,
and therefore it is required to write file register files. Also, when files are stored in the CPU module, they
must be read to other place before the capacity of the file storage area is changed and written back to the
CPU module after the change.
Default capacity of each area
The default capacity of each area is as follows.
The capacity of the local device area to be set is obtained by deducting the total capacity of the device area,
label area, latch label area, and file storage area from the total capacity of the device/label memory of each
model. However, even if the total capacity of the device area and label area is smaller than the following, the
capacity cannot be assigned to the local device area. (The area which is smaller than the following is the area
not used.)
• R08PCPU: 50K words
• R16PCPU: 60K words
• R32PCPU: 70K words
• R120PCPU: 90K words
The setting range of the capacity of each area
The following tables list the setting range of the capacity of each area on the device/label memory.
* 1
The availability of an extended SRAM cassette varies depending on the CPU module used. For the availability, check the
performance specifications of the extended SRAM cassette. ( Page 78 Extended SRAM Cassette)
*1 The rest of other areas are automatically set as the capacity of the local device area.
