A Smart I/O module has its own on-board microcontrollers. The modules described in this chapter are Smart I/O modules. During initialization of a smart module, the module's microcontroller turns the
LED off after power-on self-tests have passed and the CPU has initialized the module. The LED is illuminated to indicate an I/O fault.
The CPU also tells this module in which rate group each channel is to run, as well as any special information (such as the type of thermocouple in the case of a thermocouple module). At run time, the CPU then periodically broadcasts a "key" to all I/O cards, telling them which rate groups are to be updated at that time.
