Diagnostic messages
The transmitter provides diagnostic messages, which can be viewed on
the display of a HART Communicator, or in the Status window of the
ProLink software program. Messages are described in the following
instruction manuals, and in AMS on-line help:
•
Using the HART Communicator with Micro Motion Transmitters
•
Using ProLink Software with Micro Motion Transmitters
•
Using Modbus Protocol with Micro Motion Transmitters
Use a HART Communicator with the latest memory module, a Modbus
host controller, or ProLink software version 2.3 or higher to view the
following parameters:
•Drive gain
• Tube frequency
• Left and right pickoff voltages
•"Live zero"
Many of the messages that can be read with a HART Communicator, the
ProLink program, or AMS software can be read from the transmitter
display. These messages are described in
Section 7.4
, page 73.
Modbus host controllers use status bits as diagnostic messages.
In the event of a display readback failure, if the error does not clear itself
within 60 seconds, cycle power to the transmitter (turn power OFF, then
ON).
7.3 Interrogation with a HART
®
device
Connect a HART device to the communications socket on the transmitter
front panel (the socket is labeled "HART"), or use the ProLink program to
communicate with the transmitter.
• If the HART Communicator does not offer RFT9739 "Dev v4" as a
device description, the communicator memory module might need to
be upgraded.
• Use ProLink software version 2.3 or higher.
• Use AMS software.
• Contact the Micro Motion Customer Service Department to upgrade
your HART Communicator or ProLink program:

Figure 7-1
, page 71, explains how to connect a HART Communicator,
the ProLink PC Interface adaptor, or AMS serial modem to the
RFT9739. For more information, see the HART Communicator or
ProLink software instruction manual, or AMS on-line help.
