Polled - a master initiates communication by sending its polled I/O
message to the module. The 2 input module scans the inputs producing a
response that reflects their status.
Change of state - productions occur when an input changes. If no input
change occurs within the expected packet rate, a heartbeat production
occurs. This heartbeat production tells the scanner module that the module
is alive and ready to communicate.
