*1 The size unit of the files stored in the memory area differs depending on the CPU module.
For details, refer to the following.
QnUCPU 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.
QnUCPU 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.
