INTRODUCTION
8/2022
INTRODUCTION
The SCM Series of SolaHD Communication Modules provides network connectivity support for one or two
SDN-D Series power supplies over popular industrial protocols. The SCM-W-HRT7 model provides wired HART
protocol support and is fully HART certied.
FEATURES
• Provides a means to connect to two SDN-D Power Supplies to a HART 7 network
• Built-in thermal sensor to measure the device’s internal temperature. Since the SCM
generates minimal heat itself, the internal temperature of the SCM should be a good proxy
for ambient temperature.
WHAT'S INCLUDED
SCM-W-HRT7 is shipped with the following items:
• 1 x SCM-W-HRT7 Communication Module
• 2 x I2C cables
• SCM Comm Modules Safety Instruction Sheet
ADDITIONAL REQUIREMENTS (NOT INCLUDED)
The following items/accessories not included in the SCM-W-HRT7 package are also needed:
• Device Description (DD) le (www.solahd.com under SDN-D Documents & Drawings)
COMPATIBLE DEVICES/APPLICATIONS
SCM-W-HRT7 is designed to support all SolaHD SDN-D power supplies. As a HART compliant device, it is
designed to work with Emerson's DeltaV™, AMS Device Manager and TREX and other HART Masters.

1.5.2 CONNECTING TO DELTAV CHARM IO
The communication module can be connected to any HART 2-wire analog input channel wherein the
HART loop can be powered from the built in 24V supply.
Figure 1.5.2: Connection to CHARM IO
1.5.3 CONNECTING TO DELTAV TRADITIONAL IO
The communication module can be connected to DeltaV Traditional IO module (S Series or M Series) in
couple of congurations. The HART loop can be either powered from the built in 24V supply in the HART
IO module or this can be a separate power supply as illustrated in the gures below.

1.5.4 ESTABLISHING MULTI-DROP COMMUNICATION
Multi-dropping refers to the connection of several devices to a single communications transmission
line. Communication between the host and the devices takes place digitally with the analog output
of the transmitters deactivated. With the Field Communications protocol, up to 15 devices can be
connected on a single twisted pair of wires or over leased phone lines. A Field Communicator can
test, congure, and format a multi-dropped device in the same way as in a standard point-to-point
installation. Each device is identied by a unique address (1–15) and responds to the commands dened
in the HART protocol.

CHANGING A TRANSMITTER ADDRESS
To activate multi drop communication, the device poll address must be assigned a number from 1–63
for HART Revision 7. Each device in a multi dropped loop must have a unique poll address.
CHANGE TRANSMITTER ADDRESS USING AMS DEVICE MANAGER
1. Right click on the device and select Congure from the menu.
2. Select Manual setup.

2. CONFIGURATION
2.1 OVERVIEW
To congure on the bench, required equipment includes a power supply and Field Communicator or AMS
Device Manager. Connect the equipment as shown in Figure 2.2. Connect HART Communication leads at any
termination point in the signal loop. To ensure successful HART Communication, a resistance of at least 250
ohms must be present between the device and the power supply. Connect the Field Communicator leads to
the clips behind the power (+,–) terminals on the front of the device.
2.2 CONFIGURATION USING AMS TREX
The AMS Trex Field Communicator is a handheld device that exchanges information with the transmitter
from the control room, the instrument site, or any wiring termination point in the loop. To facilitate
communication, connect the Field Communicator, shown in this manual, in parallel with the transmitter
(see Figure 2.2). Use the loop connection ports on the rear panel of the Field Communicator. The
connections are non-polarized. Before connecting the Field Communicator in an explosive atmosphere
make sure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive
eld wiring practices. As stated in System readiness, it is critical that the latest DDs are loaded into the Field
Communicator for optimal transmitter performance. Visit www.solahd.com to download latest DD library.
Turn on the Field Communicator by pressing the ON/OFF key. The Field Communicator will search for a HART-
compatible device and indicate when the connection is made. If the Field Communicator fails to connect, it
indicates that no device was found. If this occurs, refer to Troubleshooting.

2.3 CONFIGURATION USING AMS DEVICE MANAGER
With an AMS Device Manager software package, you can commission and congure the device, monitor
status and alerts, troubleshoot from the control room, perform advanced diagnostics, and automatically
document activities with a single application. Full conguration capability with AMS Device Manager
requires loading the most current Device Description (DD) for this device. Download the latest DD at
www.solahd.com or Fieldcommgroup.org.
2.4 HART CONFIGURATION LOCK
The HART software lock prevents changes to the device conguration from all sources; all changes requested
via HART by the Field Communicator, AMS Device manager will be rejected. The HART Lock can be enabled or
disabled with a Field Communicator or AMS Device Manager.
PROCEDURE USING THE AMS DEVICE MANAGER
1. Right click on the device and select Congure.
2. Under Manual Setup select the Security tab.
3. Select the Lock/Unlock button under HART Lock (Software) and follow the screen prompts.
2.5 BASIC CONFIGURATION OF COMMUNICATION MODULE
CONFIGURING THE DEVICE VARIABLES
Mapping HART variables using the Field Communicator The “Variable Mapping” menu displays the
sequence of the process variables. Select the sequence below to change this conguration.
The device allows selection of the Primary Variable (PV), Secondary Variable (SV), Tertiary Variable
(TV), and Quaternary Variable (QV). Variable choices are various parameters of the power supply units
connected to either Channel 1 or Channel 2 of the communication module. The following table lists
the selectable variables, ranges and units.

2.6 DEVICE INFORMATION CONFIGURATION
Access the device information variables online using the Field Communicator or other suitable
communications device. The following is a list of device information variables, including device identiers,
factory-set conguration variables, and other information.
TAG, DATE, DESCRIPTOR, AND MESSAGE
The Tag, Date, Descriptor, and Message are parameters that provide device identication in large
installations. The Tag variable is the easiest way to identify and distinguish between different device.
It is used to label the devices electronically according to the requirements of the application. The
dened Tag is automatically displayed when a HART-based communicator establishes contact with
the device at power-up. The Tag is up to eight characters and the Long Tag (a parameter introduced
with the HART 6 and 7 protocol) was extended to 32 characters long. Neither parameter has any
impact on the primary variable readings of the transmitter, it is only for information.

User Guide
A272-366
The Date is a user-dened variable that provides a place to save the date of the last revision
of conguration information. It has no impact on the operation of the device or the
HART-based communicator.
The Descriptor variable provides a longer user-dened electronic label to assist with more specic
device identication than is available with tag. The Descriptor may be up to 16 characters long and
has no impact on the operation of the device or the HART based communicator.
The Message variable provides the most specic user-dened means for identifying individual device
in multi-transmitter environments. It allows for 32 characters of information and is stored with the
other conguration data. The Message variable has no impact on the operation of the device or the
HART-based communicator.
INPUT DEVICE INFORMATION USING AMS DEVICE MANAGER
1. Right click on the device and select Congure.
2. In the left navigation pane select Manual Setup.
3. On the Device Tab there will be a group box called identication. Enter the desired characters in
the Tag, Date, Descriptor, and Message elds
