What this document does
not tell you
This document does not explain how individual mapped addresses are
used. This document is a list of mapped addresses that are available for
Micro Motion transmitters that support Modbus protocol.
This manual does not explain terminology and procedures for using
Modbus protocol, or how to use a host controller to communicate with
other devices in a Modbus-compatible multidrop network. For detailed
information about using Modbus protocol, contact Modicon, Inc., North
Andover, Massachusetts, U.S.A.
For detailed information about using the mapped addresses that are
listed in this document, see Using Modbus Protocol with Micro Motion
Transmitters, available on the compact disc (CD) that is shipped with the
transmitter, or from our Web site (www.micromotion.com).
This manual does not explain transmitter installation or flowmeter wiring.
For information about installation and wiring, see the following manuals:
• Series 1000 and 2000 Instruction Manual
• Micro Motion T-Series Sensor Instruction Manual
• Model RFT9739 Field-Mount Transmitter Instruction Manual
• Model RFT9739 Rack-Mount Transmitter Instruction Manual
To order any of the manuals listed above, refer to the phone numbers
