POINT
The memory area for the sequence program for QCPU-A is the same as that for
MELSECNET/10. Therefore, the remainder of subtracting the memory area used
by MELSECNET/10 network parameters from the maximum 30k steps can be
used for the memory area for the sequence program.
Note that the sequence program can use only up to 22k steps when the
maximum 16k bytes are used for the MELSECNET/10 network parameters.
