Abstract
A system includes a central processing unit (CPU), a first input/output (I/O) module, and a second I/O module. The first I/O module includes a first module health controller operatively connected to the CPU. The second I/O module includes a second module health controller operatively connected to the first module health controller and the CPU. One of the first module health controller and the second module health controller is configured to assert a paired module health signal to the CPU indicating that the first I/O module and the second I/O module are health.
