Scope
This document discusses the supported features of HART and how these features are related to the M2000. This document
also discusses special considerations and the type of data that is accessible over HART. This document is intended for readers
who have a general understanding of the HART protocol. For further information regarding the HART protocol please refer to
www.hartcomm.org.
The M2000 HART daughterboard supports Universal Command Revision 7.

INTRODUCTION
HART protocol provides the means for sending and receiving digital information across analog wires. HART is a bi-directional
communication protocol that provides data access between intelligent field instruments (like the M2000) and host systems
(like the Emerson Field Communicator). HART technology is a master/slave protocol, which means that a field device only
speaks when spoken to by a master. The M2000 operates as a slave device. In order to connect with the M2000 using the HART
protocol, the HART daughterboard is required. As an accessory module to the M-Series M2000, the HART daughterboard
allows access to many of the M2000 measurements and configuration data using the analog wires. In addition, the HART
daughterboard allows for real-time control and monitoring of the M2000.
The Device Description (DD) files for the M2000 are located on www.hartcomm.org under Product Catalog > All Products >
M2000. These files describe the supported features and functions of the M2000 with respect to HART. The DD includes details
of menus and graphic display features to be used by host applications in order to access all parameters and data in the
M2000. These files describe what parameters are accessible and should be installed in host systems.
In order to provide access to the M2000 over HART, the daughterboard converts HART protocol commands to
MODBUS™ RTU commands.

Installation

INSTALLATION
Prerequisites
Installing a HART daughterboard into an M2000 has two requirements:
• Firmware v1.10 or later.
• M2000 PCB serial number must indicate that the board was manufactured week 19 of Year 2011 or later.
The PCB serial number is listed in the menus at Main Menu > Info/Help > Serial Number.
The PCB serial number is of the following format: WWYYSSSS, where WW = Week, YY = Year.
A label on the main board also indicates the week and year.

Figure 2: Main Board Label

Installing the Daughterboard

The daughterboard connects to the 11-pin connector labeled as COMMUNICATION on the main amplifier.

 Installation

Follow these steps to install the daughterboard:

1. Prior to installing the daughterboard, verify or configure the M2000 Communication Port B. Access the port settings at
Main Menu > Communications > Port B Settings.
Parameter Value Comments
Port Address 001 —
Extended Port Address — Not applicable for HART
Baud Rate 38400 HART Daughterboard auto-bauds, all baud rates supported
Data Bits 8 —
Parity EVEN —
Stop Bits 1 —
2. Verify or configure the analog output range at 4…20 mA.
Access the analog output range at Main Menu > Inputs/Outputs > Analog Output Range.
3. Power off the M2000.

DISCONNECT THE INPUT POWER BEFORE ACCESSING THE EQUIPMENT.

This step is important for the M2000 to properly recognize the HART daughterboard and fulfill HART compliance.
4. Prior to inserting the daughterboard, install the foam insulation pad as shown below. Be sure to align the groove with the
two screws attaching the detector or wall mount bracket to the enclosure. The primary purpose of this pad is to ensure
the daughterboard is insulated from the enclosure wall. It is important to install this pad flush with the top of the
enclosure wall.
Apply insulation pad
flush with the top of
the housing.

Figure 4: Installing Foam Insulation Pad

5. Insert the daughterboard into the 11-pin connector.

6. Use the following information to make appropriate wiring of analog wires to the 4-pin customer connector.
Pin Number Pin Description Comments
41 Analog Ground —
42 Analog Signal Requires minimum loop impedance of 230 Ω for communication
43 Analog Shield Only for shielded wires
44 Chassis Jumper Connect to screw in corner
7. Power on the M2000.
8. Allow time for the daughterboard to properly power up and be recognized by the M2000 before navigating the menus.
This time is typically 5 seconds. If the HART daughterboard is not recognized, then the M2000 should be power cycled.
9. Verify recognition of the HART daughterboard. Navigate to Main Menu > Info > Help. The Daughterboard Info field indicates
the Daughterboard Type is HART.

M2000 and HART

M2000 AND HART

HART protocol has three categories of commands: Universal, Device-Specific and Common Practice. The M2000 HART
daughterboard supports only some Universal commands and Device-Specific commands. Universal commands
supported include:
Command
Command Description
Number
0 Read Unique Identifier
1 Read Primary Variable
2 Read Current and Percent of Range
3 Read Current and Four Dynamic Variables
6 Write Polling Address
7 Read Loop Configuration
8 Read Dynamic Variable Class
9 Read Device Variables with Status
11 Read Unique Identifier Associated with Tag
12 Read Message
13 Read Tag, Descriptor, Date
14 Read PV Sensor Information
15 Read Output Information
16 Read Final Assembly Number
17 Write Message
18 Write Tag, Descriptor, Date
19 Write Final Assembly Number
20 Read Long Tag
21 Read Unique Identifier Associated with Long Tag
22 Write Long Tag
38 Reset Configuration Changed Flag
48 Read Additional Device Status
Typically, these commands are used by advanced users of HART or the usage of these commands is embedded within the
DD files. With the use of the HART universal commands, device variables and dynamic variables are accessible. Device and
dynamic variables are defined later. For further understanding of the format and function of the HART Universal Commands
please refer to HART protocol documentation.
Device-specific commands are mainly for accessing many of the M2000 data parameters, including configuration, identity
and diagnostic parameters. Much of the data accessible with device specific commands is accessed through the use of the DD
files. The DD files provide all the necessary information for data management within the M2000. Installing and using the DD
files in the applications host is the most convenient method for communicating to the M2000 over HART.
Using both the HART universal commands and device-specific commands allows for complete access to the M2000
parameters, including the ability to read or write M2000 parameters. The Data Management section defines the M2000 data
and the associated HART command.

Universal Command #48 – Read Additional Device Status

Command #48 returns 8 bytes of data that is specific to the M2000 HART daughterboard. The following table defines the
status information for the reply to this command. Unused bits are not listed in the table and are always set to 0. Some of these
bits influence the device status bits shown in the Device Status Bits Set column:
Byte Bit Description Class Device Status Bits Set
0 Detector Error Error 4, 7
1 Empty Pipe Error Error 4, 7
2 Full Scale Flow Error Warning 0, 4
3 Totalizer Rollover Error Error 4, 7
0 4 Totalizer Rollover Status Warning 4
5 Flow Simulation Status Warning 4
Pulse Synchronization
6 Warning 4
Warning
7 ADC Interrupt Error Error 4, 7
1 0 ADC Range Error Error 4, 7
Internal Communication
0 Error 4, 7
4 Failure
1 Configuration Error Warning 4
The “internal communication failure” status bit, byte 4 bit 0, is set when MODBUS communication between the meter and the
daughterboard have failed. Verify that the diagnostic, bi-color LED on the daughterboard is blinking both status indicators
(red and green). If both colors are not observed, then power cycle the meter.
The “Configuration Error” status bit, byte 4 bit 1, is set when a mismatch between the meter’s configuration and that reported
over the HART protocol. Generally, this implies the intended value for the parameter was invalid. Below are some examples for
how this bit could be set.
Example #1: Intended value is invalid
If the configured function for output #1 is set to 24V DC supply, the output type has to be normally open. If the intended
value for the output type is normally closed, the configuration error flag will be set indicating the intended value was invalid
due to its dependency on the function of the output.
Example #2: Writing to a secured meter
If connected to a secured meter, and you try to change a parameter after the login timer has expired, the “Configuration Error”
indicates that the parameter image between HART and the M2000 is not equal.

Additional Features

ADDITIONAL FEATURES
Security
The M2000 Security feature, when enabled, also applies to remote access (that is, HART). Refer to the M2000 IOM for
information on how to configure security.
Remote reads are always allowed regardless of security rights. Remote writes using the HART protocol are not allowed unless
the user has remotely logged into the meter with the appropriate access level. The remote login pins are the same as the login
pins that are used on the M2000 display.
Remote writes are not allowed if a user is actively navigating the menus at the display. Remote login expires five minutes after
the last remote write. To remotely logout more quickly, do one of the following:
• Write an invalid pin to the Remote Login parameter.

• Send a remote logoff action request to the Service parameter.

Access levels for writable parameters are defined in the Data Management section.
The security status of the meter is accessible using device specific command #243. The response data is defined in the
following table:
Bit Definition
0 If set indicates meter is secured
1 If set indicates menu access level is NONE
2 If set indicates menu access level is USER
3 If set indicates menu access level is SERVICE
4 If set indicates menu access level is ADMIN
5 If set indicates menu access level is FACTORY
6 Not Defined
7 Not Defined
8 If set indicates remote access level is NONE
9 If set indicates remote access level is USER
10 If set indicates remote access level is SERVICE

 Additional Features

Fixed Current Mode (Multi-Drop)

The M2000 provides an active analog output. This means it is the source of the analog signal. When placing the meter into
fixed current mode, the M2000 shall fix the output current to 4 mA regardless of the primary variables value (that is, Flow
Rate). During this condition the device status bit 3 (PV Analog Channel Fixed) is set.
To place the meter into fixed current mode, the polling address must be non-zero. This is a HART specific parameter. The
polling address is not accessible within the M2000 menu structure. Changing this value when the meter is secured is not
prevented. With reference to the HART DD, this parameter is located at Configuration > Hart > Hart Output > Poll Addr.
Each meter to be commissioned for multi-drop should exercise the following procedure. The default polling address for all
HART daughterboards is 0.
1. Turn off power to all meters to be commissioned for HART multi-drop mode.

IIMPORTAN
As a result of the M2000 having an active analog output, only five M2000s can be configured for multi-drop mode within the
same network.
2. Wire the meters in parallel as shown in Figure 5:

41 42 43 44 Polling Address = 1

41 42 43 44 Polling Address = 2

41 42 43 44 Polling Address = 3

Amp Meter

Figure 5: Wiring Meters in Parallel

3. Turn on power to one of the meters.

4. Change the polling address to desired address. As a suggestion, it may be desirable to change the installation data
while changing the polling address. Installation data can provide additional means for identifying the meter on the
HART network.
5. Repeat this procedure until all nodes on the HART multi-drop network are configured with a non-zero and unique
polling address.

IIMPORTAN
The analog output alarm mode has no effect while the meter is configured for multi-drop mode.

Navigate to Configuration > M2000 > Advanced > Empty Pipe and select Empty Pipe Calib to start the application. Follow the
on-screen instructions for further details.
• It may take up to 30 seconds for each pipe condition’s reading to stabilize. During this time, the following message
displays, “Wait while reading stabilizes.“

• Executing the empty pipe calibration application will leave Empty Pipe enabled regardless of the state prior to
execution.

Analog Output Calibration

Analog Output Calibration is an application embedded within the DD file that allows for remote configuration of the analog
output. Navigate to Configuration > M2000 > Advanced > Analog Output and select D/A Trim. Follow the on-screen instructions
for further details.
Do not exercise the D/A Trim application if meter is configured in multi-drop mode. The output current is fixed in multi-drop
mode (that is, Polling address is non-zero).
This application uses the custom offsets. The deviation from 4 mA and 20 mA must be entered in terms of milliamperes.
Recalibration will take effect once all offsets are configured and the application has completed.

 Device Description

DEVICE DESCRIPTION
The device descriptions, located on www.hartcomm.org under Product Catalog > All Products > M2000, can be installed into
host systems such as the Emerson 475 Field Communicator.
Periodically, the device description monitors the attached device for non-zero status codes (universal command #48). These
codes inform the user of the status of the M2000. If the status of the M2000 does not clear, these informational dialogs will
continue to be presented. To reduce the amount of dialogs, correct the state of the meter or configure the host to ignore
these non-zero status codes.
In addition, performing changes to the meter’s configuration generates a “configuration changed” status dialog. This bit must
be manually cleared to prevent future display of this dialog. This can be done within the DD file by navigating to
M2000>Advanced>Miscellaneous>Service>Reset Config Change or separately issuing universal command #38.
