The CPU shared memory is accessible only when the number of CPUs is set to 2
or more in <<Multiple CPU settings>> of C Controller setting utility.
If the CPU shared memory is accessed without setting two or more CPU modules,
CPU No. error (return value: -28662) is detected.
For the bus interface functions, refer to the following.
