*1 Up to 3 bytes are added to the total file size so that the size will be a multiple of 4 bytes.
*2 S4 is added only when local devices are used.
*3 When the number of device points that is assigned to local devices is 0, N5 is 0.
When the CPU module versions are different, a program which can be written to a CPU module with a certain
version may not be written to the one with another version due to overcapacity. In this case, delete the steps
reserved for online program change (default: 500 steps) and write the program to the CPU module.
