Overview of Sub CPU Synchronization
You can connect more than one CPU Unit through a bus to completely synchronize operation of the Main
CPU Unit and Sub CPU Units. The locations of the CPU Units are used to automatically determine which
CPU Unit is the Main CPU Unit and which CPU Units are the Sub CPU Units.
The following figure shows a system configuration example.
