Retrieve Additional Information About the HART Device
The module automatically acquires and then stores information about the
HART device that is connected to a channel and this data can be retrieved
using the MSG instruction. You can get information such as the device
identity or additional status information that the device might have on its
current condition. The module request is called "Get Device Information" and
each reply data structure will return specific elements of HART data that is
referenced by what HART command was issued to retrieve that piece of the
HART data. Refer to the HART device user manual or the HART
specification for a more detailed explanation of each data element.
