6-6 Flow
diagrams
The next two pages show basic flow diagrams of the C200HW-CORT21-V1.
These flow diagrams give a better understanding of the different states and
state transitions, and they show the relationship of the different status and
error handling mechanisms.
The first diagram describes the flow after power-on or a reset. The other two
diagrams describe the interrupt driven processes: I/O refresh and
CAN(open).
Note that these diagrams only describe the fundamentals of the unit's
functionality.
