*4 The number of executable programs in the CPU module is up to 124.
*5 A single write operation may not be counted as one.
The count of writing to the program memory or standard ROM can be checked with the special register (SD682 and
SD683, or SD687 and SD688, respectively).
*6 The number of points can be changed within the setting range. For the setting range, refer to the following.
QnUCPU User's Manual (Function Explanation, Program Fundamentals)
*7 The step relay is a device for the SFC function.
*11 The numbers are total numbers of directories that can be created when a file or folder name length is under 13
characters (including an extension). If the file or folder name length is over 13 characters or the name includes lower-
case characters, the maximum number of directories is decreased.
