Revision 8 SLG 700 SmartLine Guided Wave Radar User’s Manual 1
1 Introduction
1.1 Overview
The SLG 700 Guided Wave Radar SmartLine transmitter is an electronic instrument
designed to measure levels of liquid and solid materials. Guided Wave Radar (GWR)
transmitters use time domain reflectometry with radar pulses guided by a metal probe and
reflected off a product surface to determine levels in tanks. In comparison to other level
measurement technologies, GWR provides a highly-accurate, cost-effective, reliable
measurement over a wide range of process conditions.
1.2 Transmitter Models
The SmartLine Guided Wave Radar (GWR) transmitter is available as a family of
SLG72X models for liquid applications. The pressure and temperature application ranges
for each model are summarized in Table 2-1.

Note:
Each process connector design accepts a sub-set of the full range of probe types.
Page 4 SLG 700 SmartLine Level Transmitter User’s Manual Revision 8
Probe
The purpose of a Guided Wave Radar probe is to guide radar pulses produced by the radar
transmitter towards the material being measured. It also guides the reflected pulse back to the
transmitter for processing into a level measurement. The probe can be made of a single
conductor such as for single wire or rod probes, or two conductors for coaxial probes. For rigid
probes (rod and coaxial), multiple segments, each up to 2m long, can be connected.
The probe is also known in the industry as “waveguide”.
A single wire probe is the most common design; other designs are provided based on
application needs. For the purposes of this document the term “Wire” is being used, however
the term “Wire” and “Rope” are interchangeable.
Table 2-3 summarizes advantages and disadvantages of different probe constructions.
Installation details of each probe are described in Chapter 3.

1.4 Communicating with the Transmitter
It is possible to remotely monitor and configure a transmitter using either the HART or
FOUNDATIONTM Fieldbus (FF) protocols. Alternatively, with the HART option, the
transmitter can be monitored using the analog current, and with both interfaces, can be
configured using the three-button interface and display.
Note:
The protocols are not interchangeable. Each protocol uses
significantly different terminal and communication boards that are
installed before shipping.
4-20 mA HART
The output of a transmitter configured for the HART protocol includes two primary modes:
Point-to-Point Mode: one transmitter is connected via a two-conductor, 4-20mA
current loop to one receiver.
Multi-Drop Mode: several transmitters are connected through a two-conductor
network to a multiplexed receiver device.
The major difference between the two modes is that in Point-to-Point mode, the average
value of the loop current represents the current value of an analog signal representing the
process inside the tank. In multi-drop mode, the average value of the loop current is fixed,
usually at 4mA. Therefore, in Point-to-Point mode, an external control system can read the
Primary Variable (PV) through an analog input without HART messaging, whereas in multidrop mode, the PV can only be read as a digital value using HART messaging.
Note:
In the HART system, the abbreviation PV is used to denote the
Primary Variable which may be only one of a number of process or
device variables that may be available.
SLG 700 supports HART version 7 and its associated backward compatibility. The analog
signal is modulated by Frequency Shift Keying (FSK), using frequencies and current
amplitude that do not affect analog sensing at the receiver. The accuracy of the analog level
must be precisely controlled for accurate sensing. HART communication will not bump
process variables. In multi-drop mode, theoretically up to 16 devices in HART 5 (addresses
0-15) or up to 64 devices in HART6/7 (addresses 0-63) can exist on the two-conductor
network. Practically, the number of devices in a multi-drop installation is limited due to
design constraints. When installing into a multi-drop network, consider that the SLG700
requires a minimum startup current of 17mA and a minimum terminal voltage of 11V during
startup. After this initial startup period (approximately 0.5 seconds), the loop current will be
fixed at 4mA, and the minimum terminal voltage is 14V. The power source, wiring, intrinsic
safety barriers, and other devices in the network be considered to ensure these requirements
can be met.
Note:
The SLG700 requires a minimum startup current of 17mA, even when configured in
multi-drop mode. The minimum terminal voltage is 11V during startup. After startup, the
loop current will be fixed at 4mA, and the minimum terminal voltage should be 14V.
Revision 8 SLG 700 SmartLine Level Transmitter User’s Manual Page 7
Figure 2-2 is an example of a HART connection to the transmitter. The communication
resistor RL may be inserted anywhere in the 4-20 mA loop but it is recommended to be
installed close to the positive supply. Refer to section 0 for acceptable power supply and RL
ranges
The MC Toolkit is a dedicated Honeywell communication tool that uses Device Description
(DD) files to communicate with multiple transmitter models. Also, other equivalent tools or a
HART-to-USB converter may be used. Device Description files are available from:

FOUNDATIONTM Fieldbus (FF)
The Honeywell SLG 700 is a SmartLine Level transmitter that has a wide range of additional
features along with supporting the FOUNDATIONTM Fieldbus (FF) communication protocol.
The SLG 700 level transmitter with FF protocol provides a FOUNDATION Fieldbus
interface to operate in a compatible distributed Fieldbus system. The transmitter includes
FOUNDATION Fieldbus electronics for operating in a 31.25 Kbit/s Fieldbus network and
can interoperate with any FOUNDATION Fieldbus registered device.
The Honeywell SmartLine SLG 700 is a high-performance transmitter offering high
accuracy, reliability and resolution over a wide range of process conditions.
The SLG 700 Fieldbus device is fully tested and compliant with Honeywell Experion® PKS
providing the highest level of compatibility assurance and integration capabilities.
Figure 2-3 graphically represents the connection of the transmitter to a FF handheld device. A
similar connection may be realized using PC configuration software.
Each transmitter includes a configuration database that stores its operating characteristics in a
non-volatile memory.
The handheld or PC software is used to establish and/or change selected operating parameters
in a transmitter database. The process of viewing and/or changing database parameters is
called configuration.
Configuration can be accomplished both online and offline with the transmitter powered up
and connected to the handheld.
Online configuration immediately changes the transmitter operating parameters. For offline
configuration, transmitter operating characteristics are entered into the handheld memory for
subsequent downloading to transmitter.

DTM-based tools and Experion
HART and FOUNDATION Fieldbus models support Device Type Managers (DTMs)
running on Field Device Technology® (FDT) hosts such as PACTware or Field Device
Manager (FDM) / Experion.
The transmitter establishes communication with the host systems using DD or DTM.
Device Description (DD)
DD is a binary file that provides the definition for parameters in the FBAP of the
transmitter. For example, DD refers to the function blocks that a transmitter contains, and
the corresponding parameters in the blocks that are critical to the interoperability of
Fieldbus devices. They define the data required to establish communications between
different Fieldbus devices from multiple vendors with control system hosts. The DD
provides an extended description of each object in the Virtual Field Device (VFD).
The Fieldbus Foundation provides the DD for all registered devices on its website,
http://www.fieldbus.org/index.php?option=com_mtree&task=viewlink&link_id=1991&ff
bstatus=Registered&Itemid=324
Page 10 SLG 700 SmartLine Level Transmitter User’s Manual Revision 8
Enhanced Device Description (EDD)
There are two types of EDDs are available, namely .ff5/.sy5 and .ffo/sym. The .ffo/.sym
binary files are generated for the legacy hosts to load the device DD that is generated using
latest tokenizer. Few constructs like Images that are supported in .ff5/.sy5 binaries, are not
supported in .ffo/.sym binary files.
Device Type Manager (DTM)
The DTM is similar to a device driver that enables usage of devices in all the asset
management and device configuration software like FDM or PACTware, with the help of the
FDT-DTM technology.
The DTM has the following primary functions:
Provides a graphic user interface for device configuration.
Provides device configuration, calibration, and management features for the
particular device.
The DTM provides functions for accessing device parameters, configuring and operating the
devices, calibrating, and diagnosing problems.
Download the DTM from: https://www.honeywellprocess.com/en-
US/explore/products/instrumentation/process-level-sensors/Pages/smartline-leveltransmitter.aspx

1.6 Transmitter Model Number Description
The model number is comprised from a number of selections and options that can be specified
when ordering the transmitter. It includes a basic transmitter type such as SLG720 (standard
temperature, standard pressure) followed by a maximum of nine additional character strings
that can be selected from a corresponding Table in the Model Selection Guide (MSG).
The basic model number structure is shown in Figure 2-6.
Figure 2-6: Standard SLG 700 Model Number
For a more complete description of the various configuration items and options, refer to the
SLG 700 Product Specification (34-SL-03-03) and Model Selection Guide (34-SL-16-01).
1.7 Safety Certification Information
SLG transmitter models are available for use in hazardous locations, including CSA, IECEx,
ATEX, and FM approvals. See Appendix Certifications for details and other approvals. The
transmitter will include an “approvals” nameplate mounted on the electronics housing with the
necessary compliance information.
Figure 2-7: Safety certification example
Safety Integrity Level (SIL)
The SLG 700 is intended to achieve sufficient integrity against systematic errors by the
manufacturer’s design. A Safety Instrumented Function (SIF) designed with this product must
not be used at a SIL level higher than the statement, without “prior use” justification by the
end user or diverse technology redundancy in the design. Refer to the SLG 700 Safety Manual,
Document #34-SL-25-05, for additional information. The SIL level will be indicated on the
SLG 700 nameplate.
See the SLG 700 Transmitter nameplate for additional information, Figure 2-5.
Page 14 SLG 700 SmartLine Level Transmitter User’s Manual Revision 8
1.8 Security Considerations
The SLG 700 provides several features designed to prevent accidental changes to the device
configuration or calibration data. These features include a local display password (HART
option), a communication password (HART option), a Hardware Write Protect Jumper and a
Software Write Protect configuration parameter. These features can be used in combination to
provide multiple layers of change protection.
For both the local display and communication passwords, the initial user passwords are
defined as "0000". A "0000" password indicates that the user has not set a user- defined
password and the password protection is disabled. The password used on the local keyboard
display is separate from the password provided for communication. Password protection from
the local keyboard display does not inhibit changes by way of communication over the current
loop. A master password is available that allows recovery if the set user password is unknown.
A hardware write-protect locks out changes regardless of the entry of a password. The
hardware jumper requires physical access to the device as well as partial disassembly and
should not be modified where the electronics are exposed to harsh conditions or where unsafe
conditions exist. For configuration or calibration changes without changing the hardware
jumper position the user may choose to rely on the password and software lockout features.
A tamper mode feature (see SLG 700 SmartLine Guided Wave Radar Level Transmitter HART
Option Manual, Document #34-SL-25-06) is available that can indicate that an attempt was
made to change either the configuration or calibration of the device (whether or not a change
was actually made). These security features are designed to avoid accidental changes and to
provide a means to detect if an attempt was made to change the configuration and calibration.
Note: FF does not support tamper mode.
1.9 Measurement Options Licensing
As of software revision R200, the sensor checks whether the user has a license required to
operate the device in a particular measurement mode (see also 2.5 for the various
measurement modes). Licenses are required to measure two-liquid interfaces, use the low
DC measurement mode and for steam applications. Any sensor ordered for these application
will have a valid license key stored in the transmitter and no user action is required.
The license key depends on the device ID which can be checked using the display (see
Table 4-8 or DTM. It is possible to obtain new license keys for application types other than
which the gauge was originally bought for by supplying the device ID to Honeywell and
entering the newly obtained license key.
Gauges that were installed prior to R200 do not lose access to the interface measurement
when they are upgraded to the new software - the sensor will internally generate a license key
for this application after the first startup and store it in memory.
