I/O Registers Used for Sub CPU Synchronization
There are the following two types of registers for the Main CPU Unit and Sub CPU Units.
• High-speed scan CPU interface registers: Exchange data in the high-speed scan.
• Low-speed scan CPU interface registers: Exchange data in the low-speed scan.
These registers are assigned to CPU interface registers for the Safety CPU Unit service.
You can set the ranges of the CPU interface registers on the Module Configuration Definition Tab Page on
the MPE720.
