Check that CPU's program capacity is adequate for storing the program and
parameter data.
The program capacities of the CPUs are shown below:
• Q00JCPU : 8 k steps
• Q00CPU : 8 k steps
• Q01CPU : 14 k steps
Consider the applications of the devices used in a program and their number of
points.
Refer to Chapter 10 for the devices usable with the Basic model QCPU.
