About This Document
This guide provides the details of programming Honeywell SMV800 Multivariable Transmitters for
applications involving Modbus protocol.
For installation, wiring, and maintenance information, refer to the SMV800 Multivariable
Transmitter User Manual, Document # 34-SM-25-03.
The configuration of your transmitter depends on the mode of operation and the options selected for
it with respect to operating controls, displays and mechanical installation.
To digitally integrate a Transmitter with one of the following systems:
For the Experion PKS through SCADA, Experion HS, you will need to supplement the
information in this document with the data and procedures in the Experion Knowledge
Builder.
For Honeywell’s TotalPlant Solutions (TPS), you will need to supplement the information
in this document with the data in the PM/APM SmartLine Transmitter Integration Manual,
which is supplied with the TDC 3000 book set. (TPS is the evolution of the TDC 3000).

1. Introduction
1.1 Overview
This section is an introduction to the physical and functional characteristics of Honeywell’s
family of SMV800 Modbus transmitters.
1.2 Features of the transmitter
The SMV800 SmartLine Multivariable transmitter type SMV800 Modbus supports
standard Modbus RTU transmission mode with measurement capability of process
variables: DP (Differential Pressure), SP (Static Pressure), PT (Process Temperature),
Flow, Totalizer and MBT (Meter Body Temperature).
Table 1-1 lists the protocols, human interface (HMI), materials, approvals, and mounting
bracket options for the SMV800 Modbus transmitter. The transmitter does support
SmartLine advance diagnostics such as Process Variables monitoring, Tamper Alarm and
Stress monitoring.

and 316SS
Approvals (See SMV Transmitter Users manual,
34-SM-25-03 Appendix for details.)
FM, CSA, ATEX, IECEx, SAEx/CCoE,
INMETRO, NEPSI, KOSHA, EAC and Explosion-
proof options
1.2.1. Tamper Functionality
When the write protection is enabled, if any unauthorized person tries to change the
device configuration, then “Tamper counter” gets incremented and if it crosses the
“Maximum number of tamper attempts” then Tamper alarm warning is triggered

Page 2 SMV800 Modbus User's Guide Revision 1.0
1.2.2. Advanced Diagnostics
1.2.2.1. Error Log
Error Log feature provides information related to relative time stamp of errors/faults
detected by device. The device can store last 10 errors occurred when error log feature
is enabled. There is also provision to reset error log to capture the new errors. We can
read the error log information and the elapsed time since the error occurred from host
application.
1.2.2.2. Configuration Change History
The feature provides history for parameters configuration change.
For example, if Differential Pressure damping is modified from 2.0 to 3.0 then using
configuration history user can find that previous value of DP damping is 2.0.
Device can hold history for last 5 configured parameters data.
1.2.3. Physical Characteristics
As shown in Figure 1-1, the SMV800 is packaged in two major assemblies: the Electronics
Housing and the Meter Body. The elements in the Electronic Housing respond to setup
commands and execute the software and protocol for the different pressure measurement
types. Figure 1-1 shows the assemblies in the Electronics Housing with available options.
The Meter Body provides connection to a process system. Several physical interface
configurations are available, as determined by the mounting and mechanical connections,
all of which are described in the SMV Transmitter Users Manual, see References
.
Figure 1-1: SMV800 Major Assemblies

Revision 1.0 SMV800 Modbus User's Guide Page 3
1.2.4. Functional Characteristics
The SMV800 Modbus transmitter supports standard Modbus RTU transmission mode with
configurable serial communication parameters such as baud rate and parity.
The SMV800 Modbus transmitter measures Differential Pressure, Static Pressure
(Absolute or Gauge), and Process Temperature. The SMV800 measures Process
Temperature from an external RTD or Thermocouple.These measurements are used to
calculate volumetric or mass flow rates and Totalizer. The measured values and calculated
flow may be read by a connected Host. Support of temperature sensing using
Thermocouple and computation of volumetric flow are separate software optional features.
An optional 3-button assembly is available to set up and configure the transmitter via the
Advanced Digital Display. In addition, a Honeywell SMV Modbus PC based application is
available for configuration of transmitter parameters.
1.3 SMV800 Transmitter Name Plate
The transmitter nameplate mounted on the bottom of the electronics housing (see Figure
1-1) lists certifications. The model number, physical configuration, electronic options,
accessories are located on the Product I.D. nameplate (see Figure 1-2).
Figure 1-2 is an example of a SMV800 for the name plate information. The model number
format consists of a Key Number with several table selections.
Figure 1-2: Typical SMV800 Name Plate
E.g. SMA810, SMA845 or SMG870
You can readily identify the series and basic transmitter type from the third and fourth
digits in the key number. The letter in the third digit represents one of these basic
measurement types for the Static Pressure:
A = Absolute Pressure
G = Gauge Pressure
For a complete selection breakdown, refer to the appropriate Specification and Model
Selection Guide provided as a separate document.
