10.14 Convenient Usage of Devices

Basic When executing multiple programs in the CPU module, local devices among the internal
user devices can be designated to execute each of the programs in an independent
Note10.32
manner.
Basic CPU module devices are classified into "global devices" shared by all the programs being
executed and "local devices" used independently by each of the programs.
Note10.33
10.14.1 Global
Global devices can be shared by all the programs being executed in the CPU module.
Global device data are stored in the CPU module device memory, and can be used by all
programs.
Note33

Since the Basic model QCPU cannot execute multiple programs, it does not support the function
that makes each program independent by local device designation.
Note10.32
Note34
Since the Basic model QCPU cannot execute multiple programs, it is irrelevant to the difference

between local devices and common devices. When the Basic model QCPU is used, it is not
necessary to be conscious of the description in this section.
