CPU停机与否取决于你所作的修改。如果以下任意一项设置发生变化，系统编译时将重新分配内存，导致CPU停机作完全下装：
1. Local Data setting (HW Config\CPU Properties\Memory)
2. Communication Resources (HW Config\CPU Properties\Memory)
3. Diagnostic Buffer size (HW Config\CPU Properties\Diagnostics/Clock)
4. Clock memory address (HW Config\CPU Properties\Cycle/Clock Memory)
