*1 The size unit of the files stored in the memory area differs depending on the CPU module. For details, refer to the
following.
Qn(H)/QnPH/QnPRHCPU User's Manual (Function Explanation, Program Fundamentals)
*2 The maximum number of executable sequence steps is obtained by the following formula.
(Program size) - (File header size (Default: 34 steps))
For details of the program size and files, refer to the following.
Qn(H)/QnPH/QnPRHCPU User's Manual (Function Explanation, Program Fundamentals)
*3 Data in the CPU shared memory is not latched.
Data in the CPU shared memory is cleared when the programmable controller is powered on or the CPU module is
reset.
QCPU User's Manual (Multiple CPU System)
*10 For the CPU module whose serial number (first five digits) is "16020" or earlier, the maximum memory card size is 2M
bytes.
