Change-of-State - productions occur when an input changes or a
fault condition occurs. If no input or fault condition change occurs
within the expected packet rate, a heartbeat production occurs. This
heartbeat production tells the scanner module that the I/O module is
alive and ready to communicate. Consumption occurs when data
changes and the master produces new input data to the I/O block.
