communicate with each other by an inter-module link to maintain fault
tolerant operation'.
This module supports HART commands #03 to collect data from the field
device. The application can be configured to use HART information to
monitor and respond to device conditions. It may also be used to supply
diagnostic information such as comparison and error reporting.
