Abstract
A hand-held communication and diagnostic tool is provided. The tool is able to automatically detect connection to a process control loop as well as detect the type of loop to which it is connected without substantially disturbing messaging on the loop. Once the tool determines the type of loop to which it is connected, it provides suitable communication and diagnostics appropriate to that specific type.
