4. ADDITIONAL RESPONSE CODE INFORMATION
FIRST BYTE
4.1 BUSY
Bit #5
The Busy Response Code will be returned in all cases where the command being requested cannot be
executed because it was received during the execution of a command that continued after the command
response. The command that will respond with this indication is #43. Eve n during execution of these
commands, Commands #0, #1, #2, #3, #44, #48, #131 and #132 will all be processed normally and will not
return the Busy Response Code. All other commands will return the Busy Respo nse Code.
SECOND BYTE
4.2 ANALOG OUTPUT SATURATED
Bit #2
This flag is set whenever the output current saturates below 3.8 milliamperes and above 20.5 milliamperes
4.3 NON-PRIMARY VARIABLE OUT OF LIMITS
Bit #1
This flag is set whenever a non-Primary Variable (i.e. Temperature, Density, etc.) exceeds its pre-defined
sensor limits.
4.4 PRIMARY VARIABLE OUT OF LIMITS
Bit #0
This flag is set whenever the Primary Variable exceeds the Sensor Limits returned with Command #14,
Read Primary Variable Sensor Information.

2000 Series Command Specification, Rev: 5.0 Final Release Date: 10 Oct 2006

5. GENERAL TRANSMITTER INFORMA TION
5.1 COMMAND RESPONSE TIME
The preambles of a response packet will be sent within 256 milliseconds at 1200 baud (and a minumum of
30 milliseconds at 38400 baud) following the receipt of a command. The STX of response packet will be
sent within 100 milliseconds following the receipt of a command. Therefore, more than 5 preambles may
be sent by the transmitter in response to a command.
5.2 DAMPING IMPLEMENTATION
The 2000 Series implements damping on both the digital Primary Variable and the Analog Output current.
The digital Primary Variable is damped to the Uppe r a nd Lower Sensor Limits of the transmitter. The
analog current is calculated from the digital Primary Variable and will remain saturated as long as the
damped Primary Variable remains beyond the Upper or Lower Range Values.
The 2000 Series has a limited selection of damping values for process variables. They are as follows:
Flow and Density: 0, 0.1, 0.2, 0.4, 0.8, 1.6, 3.2, 6.4, 12.8, 25.6, 51.2 seconds
Temperature: 0, 0.6, 1.2, 2.4, 4.8, 9.6, 19.2, 38.4, 76.8 seconds
If the passed parameter does not match one of these standard values, the transmitter will truncate the value
received and respond with the response code Set to Nearest Possible Value, #8.
5.3 NON-VOLATILE MEMORY DATA STORAGE
The Flag Byte of Command #0, referenced in the Universal Command Specification document, will have
Bit #1 set to 0, indicating that all data sent to the transmitter will be saved automatically in the nonvolatile
memory upon validation after being received with a Write or Set Command. Command #39, EEPROM
Control, has not been implemented.
5.4 MULTIDROP OPERATION
The 2000 Series supports full Multidrop capabilities with the RS485 or HART
The physical maximum number of transmitters connected to a multidrop network will vary from
implementation to implementation depending on Capacitance Numbers (CN) of the devices and their other
electrical properties. Typical numbers vary from 2 -15 when identifying devices by their polling address
(nickname) using command 0. It is p ossible to have an almost unlimited number of devices (the actual
number exceeds 10 trillion), given favorable physical characteristics as discussed above, when devices are
identified by Tag using command 11.
Please note that Micro Motion extends the formal specification of HART to include the RS485 physical
layer. Not all other manufacturers support the RS485 extension, so physical layer incompatibilities may be
introduced into a multidrop system if RS485 is selected.

5.7 SENSOR FLOW CALIBRATION FACTOR FORMAT
The Sensor Flow Calibration Factor will include the information required to calibrate the specific sensor
installed. This number will be 10 characters long and will have the following format:
x.xxxxy.yy
x = Gain Factor for Flow Rate in grams/second/microsecond. The decimal point can be anywhere
in the number.
y = Temperature Coefficient for Flow Rate in Percent/100 degrees Celsius. The decimal point can
be anywhere in the number.
5.8 SENSOR TEMPERATURE CALIBRATION FACTOR FORMAT
The 2000 Series will accept a 14-character temperature calibration factor in the following format:
a.aaaaab.bbbbb
a = Calculated slope for a two-point temperature calibration. The decimal point can be anywhere
in the number.
b = Calculated offset for a two-point temperature calibration. The decimal point can be anywhere
in the number.
5.9 COMMAND SECURITY
The 2000 Series supports a hardware security switch used for Custody Transfer Applications. Access to the
transmitter memory by using any supported HART® command can be de ni ed when this switch is set, thus
enabling Command Security. Once secured, attempting to write data to the transmitter will result in
response code 16, Access Restricted.
The transmitter supports a software switch that provides a write-protect function. Write protect can be
enabled and disabled using command 194 – Perform Diagnostic Action. When write protect is enabled or
turned on, “write” and “command” commands are disabled (this includes resetting the totals). “Read”
commands are still operational. Once enabled, sending a “write” or “command” command will result in
response code 7, in write-protect mode.

6. ADDITIONAL UNIVERSAL COMMAND SPECIFICATIONS
This section contains information pertaining to those commands that require clarification.
6.1 COMMAND #3 READ ALL DYNAMIC VARIABLES AND CURRENT
Read the Current and four predefined Dynamic Variables. The Digital Current always matches the Primary
Variable Analog Output current of the device incl uding alarm condit ions and set value s .
6.2 COMMAND #6 WRITE POLLING ADDRESS
This command writes the Polling Address to the field device. The address is used to control Analog Output
1 and provide a means of device identification in Multidrop installations.
With HART Rev 6, the state of Analog Output 1 is configurable when the polling address is not 0. With
HART Rev 5, Analog Output 1 was not active when the polli ng address was not 0 . This device is adopting
the HART Rev 6 ve rsion of the command; therefore, the state of Analog Output 1 is configurable.
Any other analog outputs will remain Active regardless of the polling address of the device.
When communicating over the RS485 physical layer, all Analog Outputs are Active regardless of the
polling address of the device.
6.3 COMMAND #14 READ PRIMARY VARIABLE SENSOR INFORMATION
When the Sensor Serial Number is not applicable to the device or Primary Variable, it will be set to "0".
The other parameters will be set to 7F A0 00 00, Not-a-Number, or "250", Not Used, when they are not
applicable.

7. ADDITIONAL COMMON-PRACTICE COMMAND SPECIFICA TIONS
The 2000 Series implements a subset of the Common-Practice Commands specified in the Common-Practice
Command Specification document. This section contains information pertaining to those commands that require
clarification.
7.1 COMMAND #34 WRITE PRIMARY VARIABLE DAMPING VALUE
The 2000 Series has a limited selection of damping values: 0, 1, 2, 4, 8 and 16 seconds. If the passed
parameter does not match one of these standard values, the transmitter will truncate the value received and
respond with Set to Nearest Possible Value, #8.
7.2 COMMAND #43 SET PRIMARY VARIABLE ZERO
A Set Primary Variable Zero cannot be performed unless Mass Flow Rate Volume Flow Rate has been
selected as the Primary Variable. Any attempt to do so will result in a Command-Specific Response Code
#6, Transmitter-Specific Command Error.
A Set Primary Variable Zero command will initiate a mechanical sensor zero. A mechanical zero operation
may take several minutes to complete. During this operation Command #48, Read Additional Transmitter
Status, will return Response Code #8, Warning: Update In Pro gre ss. T he Calib ration (Zero) in Progress bit
will also be set.
7.3 COMMAND #44 WRITE PRIMARY VARIABLE UNITS
The Primary Variable unit codes for this command are listed in the applicable Transmitter Variable unit
codes tables.
7.4 COMMAND #48 READ ADDITIONAL TRANSMITTER STATUS
This command returns the results of the Transmitter Self Test Command, #41, as well as other transmitter
status information.

This command allows the user to read data from a MODBUS coil or a MODBUS register. The following MODBUS
registers ar e supported: unsigned 16, uns igned 32 and floating point.
HART and MODBUS both use IEEE-754 floating point representations, but the order in which the bytes are
transported is configurable for MODBUS. For this command, the order of the floating point bytes is the HART

8.44 COMMAND #180: WRITE FAULT OUTPUT PARAMETERS
This command identifies the fault settings for each of the outputs. Each output (mA and Frequency) may be
configured for different fault settings.
The Analog Fault Level may be used to set the mA output to the upscale or downscale milliamp setting for a fault
condition. If the output type is frequency and the fault setting is upscale, the fault level may also be configured.
If the Output Type code is digital communications, the fault selection is only applicable for the Modbus protocol on
the RS485 physical layer and not HART.
The Last measured Value Fault Timeout will have a default of 0 seconds. Setting this value to anything other than 0
will result in the output holding it’s last measured value for that defined number of seconds. After the timeout period
expires, the output will proceed to the configured fault level (i.e. upscale, downscale, etc.).

8.45 COMMAND #181: READ FAULT OUTPUT PARAMETERS
This command reads what the state of the transmitter outputs will be in the event of an error condition that could
invalidate the measurement. Each output (mA and Frequency) may be configured for different fault settings.
If the Output Type code is digital communications, the fault selection is only applicable for the Modbus protocol on
the RS485 physical layer and not HART.
The Last measured Value Fault Timeout will have a default of 0 seconds. Setting this value to anything other than 0
will result in the output holding it’s last measured value for that defined number of seconds. After the timeout period
expires, the output will proceed to the configured fault level (i.e. upscale, downscale, etc.).
Note: This command is totally different from the RFT9739
