Using the Modbus Map

1.1 About this manual

®

This manual lists Modbus
Modbus protocol.

This manual does not explain how individual registers are used. For detailed information about using
the registers that are listed in this document, see Using Modbus Protocol with Micro Motion
Transmitters, available on the CD that is shipped with the transmitter, or on the Micro Motion web
site (www.micromotion.com).

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, see www.modbus.org.

This manual does not explain transmitter installation or flowmeter wiring. For information about
installation and wiring, see the appropriate sensor and transmitter manuals.

Modbus Map Using the Modbus Map

1.2 Transmitters that support Modbus protocol

Micro Motion transmitters that support Modbus protocol include:

• RFT9739 transmitters, Version 2 and higher

• Micro Motion MVD

• Series 1000 and 2000 transmitters, all versions

• LF-Series transmitters, all versions

• Series 3000 MVD (4-wire) transmitters

Note: MVD Direct Connect installations do not include a transmitter. However, a Modbus/RS-485
connection can be made to the core processor component, and Modbus commands can be used to
communicate with the core processor. See the MVD Direct Connect flowmeter installation manual for
information on setting up this connection.

In this manual, the term “MVD” refers to all of the above except the RFT9739 transmitters.

1.3 How to use this manual

This manual is designed for use as a reference manual. It lists the Modbus registers for transmitter
configuration, calibration, use, and diagnostic procedures. Some procedures are required; others are
optional.

Direct Connect™, with or without the MVD Direct Connect I.S. barrier

Using the Modbus Map continued

This manual also lists the Modbus registers for the following special applications:

• Petroleum measurement application (API feature)

• Enhanced density application

• Discrete batch application and filling and dosing application

• Net Oil Computer (NOC) application

• Custody transfer application

For each register, checkmarks indicate the transmitters for which the register is enabled.

In addition, this manual lists the integer codes that are used in configuration.

1.3.1 Register addresses

Each register is identified by its address (or starting address), which is a 4-digit number.

Depending on the PLC that will be used to communicate with the transmitter, you may need to
subtract 1 from the address or starting address of the register. Refer to your PLC documentation to
know if this applies to you.

Example

This Modbus manual specifies 0042 as the address of the register that
contains the unit for process variables that measure volume flow.

Use 0041 in the data field of the Modbus frame.

1.3.2 Register types

The register types are listed and briefly described in Table 1-1.

Note: Micro Motion terminology is a simplified version of Modbus terminology. The term “coil” is
used for both Modbus coils (read-write) and Modbus discrete inputs (read-only), and the term
“register” is used for both Modbus holding registers (read-write) and Modbus input registers (read­only).

Table 1-1 Modbus register types

Register type Size Data type Description

Coil 1 bit Binary Boolean (0 or 1, ON or OFF)

Float 16 bit Floating-point Used in pairs to store 32-bit floating-point values in single precision

Integer 16 bit Integer Unsigned 16-bit integers ranging from 0 to 65535

Long integer 16 bit Integer Used in pairs to store unsigned 32-bit integers ranging from 0 to

ASCII 16 bit 8-bit ASCII One or more consecutive registers. Each register stores two 8-bit ASCII

IEEE 754 format

4294967295 (0xFFFFFFFF)

characters (16 bits total).

1.3.3 Transmitter codes

If a register applies only to a subset of the model or series, codes are used to identify the models to
which the register applies. Codes are listed in Table 1-2.

I All transmitters with the intrinsically safe outputs option board

C All transmitters with the configurable input/outputs option board

F All transmitters with the

P All transmitters with the Profibus-PA outputs option board

N Net Oil Computer (Series 3000 transmitters with the NOC application)

1.3.4 LF-Series transmitters

The LF-Series transmitters are based on Series 1000 and Series 2000 transmitters, and use the same
Modbus interface. For this reason, they are not called out separately in this manual. All references to
Series 1000 or Series 2000 transmitter also apply to the equivalent LF-Series transmitter:

• Model 1500 includes the LF-Series: DIN Rail Flow Only

• Model 1700 includes the LF-Series: Field Mount Flow Only

• Model 2500 includes the LF-Series: DIN Rail Multivariable

• Model 2700 A includes the LF-Series: Field Mount Multivariable 1mA/1FO

FOUNDATION Fieldbus outputs option board

• Model 2700 C includes the LF-Series: Field Mount Multivariable 2mA/1FO configurable

• Model 2700 F includes the LF-Series: Field Mount F

• Model 2700 P includes the LF-Series: Field Mount Profibus-PA

1.3.5 Organization

The reference section of this manual is organized as follows:

• All coils, listed numerically by address (Table 2-1)

• All floating-point registers, listed numerically by address (Table 2-2)

• All integer registers, listed numerically by address (Table 2-3)

• All long integer registers, listed numerically by address (Table 2-4)

• All ASCII registers, listed numerically by address (Table 2-5)

• Integer codes, listed by function (Tables 2-6 through 2-44)

Additional information for a specific register or transmitter is provided in a footnote. For each table,
the page on which the footnotes can be found is listed at the top of the page.

(1) For RFT9739 transmitters, coil 14 initiates either high-density (D2) or flowing density calibration. If the flow rate is greater than

50% of full scale, coil 14 initiates a flowing density calibration; otherwise, coil 14 initiates a D2 calibration.
(2) Requires filling and dosing application.
(3) Requires appropriate hardware.
(4) Transmitter software v3.3 and higher.
(5) Requires custody transfer application.
(6) Requires petroleum measurement application (API feature).
(7) Requires enhanced density application.
(8) Transmitter software v4.1 and higher, or, for transmitters with the F

OUNDATION fieldbus outputs option board, transmitter software

v3.0 and higher.
(9) Transmitter software v6.1 and higher.
(10) Requires discrete batch application.
