(c) Precautions for formatting
1) Formatting of program memory
The High Performance model QCPU program memory can only be
used after being formatted by GX Developer.
When formatting the program memory, designate whether or not a
system area is to be allocated for user settings. (Up to 16 k steps (in 1
k-step units) can be allocated for the user setting system area.)

2) System area setting
If RS-232 and USB interfaces are connected to GX Developer, the
system area user setting data is used for registering monitor data from
the GX Developer connected to serial communication module.
The allocation of space for system and user-defined areas will make it
much easier to perform monitoring operation by operating from the GX
Developer connected to the serial communications module.
Although the designation of a user setting area speeds up monitoring
from the GX Developer connected to serial communication module, it
also reduces the amount of space available for user files.
REMARK
1) 1: This table shows an example in which 0 k step is allocated for a system area.
2) 2: In computing the memory capacity, 1 step is equal to 4 bytes.
3) 3: Maximum number of executable program is 124. More than 124 programs
can not be executed.
