If the user selects Basic setup from 8.1 HART Protocol Option Information the Device setup screen, the next screen has a mixture of further HART Communicator Overview menu selections and detailed information. This screen displays the name of the variable that is This section presents the major screen selections available to the controlling the output current (PV), user. - Page 11 If the user selects Operation Then the HART Communicator Status from the Diagnostics will report the results to the user screen, he is able to view all in sequence. In the example of the status bits indicating given here, the diagnostics has the health of the transmitter detected a problem with the Level operation.
