Introduction
This manual discusses features of the
SEM3 metering system and provides
conguration instructions.
By the time you are ready to use this guide,
your meter should be installed, most basic
SEM3™ - Embedded Micro Metering Module™
setup should have been performed, and
communications/basic operation should
have been veried. If the unit is not yet
installed and operational, refer to the
Installation Manual available on line at
www.usa.siemens.com/SEM3.
This chapter provides an overview of SEM3
meters, and summarizes many of their
key features.
The SEM3 system is designed to measure
the current, voltage, and energy
consumption of up to 45 circuits.1)
The SEM3 consists of a controller, racks,
cables, meter modules and current
transformers (CTs) that can be tailored to
the application. The CTs are available in
solid core & split core versions and are to
be mounted along the termination points
of each breaker pole being metered. The
conductor passes through the appropriate
current sensor before terminating at
the breaker. Each CT is terminated into
a meter module that in turn is mounted
in a rack. The racks get power from and
communicate back to the controller
through special cables that are part of the
SEM3 product line.
The SEM3 has the ability to communicate
Modbus RTU/BACnet MSTP via RS485,
Modbus TCP, BACnet IP, SNMP via
Ethernet port to outside systems.
The controller web pages are also used
to configure the SEM3 system to the
application. Systems info, CT ratio
setting and alarms as well as configuring
the meter modules into 1, 2, or 3 pole
meters are all accomplished through
embedded and easy to use web pages.
See the SEM3 User Manual for more
application specific information at
www.usa.siemens.com/SEM3.
1) Some applications will allow for more than 45 poles in one enclosure by adding a second controller. Two controllers can monitor up to 90 poles.
SEM3™ - Embedded Micro Metering Module™ User Manual 5
SEM3™ - Embedded Micro Metering Module™ (cont’d.)
The SEM3 system is made up of the
following components and options:
1. Controller – The controller is used to
communicate the metered values to
outside systems by way of a web page
interface, Modbus RTU or Modbus TCP.
One controller can manage up to 45
meter modules. The controller also has
the system digital inputs for receiving
pulse inputs from other metering
devices as well as a digital output for
the combined KWh output of the system
being metered.
2. Meter Modules – There are two
choices or the meter modules that are
differentiated by accuracy specication.
The accuracies are 1% for the standard
accuracy modules and 0.2% for the high
accuracy modules. The accuracy is tested
in accordance to ANSI C12.20/0.5.
3. Meter Racks – The meter modules
are designed to snap into the rack
assemblies. The rack assemblies are
sized by how many modules will t into
each and come in 3, 6, 9, 15 and 21
module congurations.
4. CT or Current Transformers – The
SEM3 systems have solid core CTs or
split core CTs for use with the system
in the following maximum amperage
ranges 50, 125, 250, 400, 600, 800
and 1200 amps. These are maximum
amperage ranges for normal usage but
will measure accurately down to 1% of
the maximum range.
5. Communication Cables – The
communication cables are designed like
CAT 5 cables but are insulated for use in
systems up to 600 volts. The cables are
for two way communication from the
controller to the rack/meter modules.

SEM3 in an Energy Management System
You can use SEM3 meters as standalone
devices, but their extensive capabilities
are fully realized when used with WinPM.
Net software as part of an enterprise
energy management (EEM) system or
Powermanager software for standalone
sub billing reports.
EEM systems give energy suppliers,
service providers, and large industrial
and commercial energy consumers
the tools to meet all the challenges
and opportunities of the new energy
environment. EEM systems use real‐time
information and control to directly address
a broad range of requirements throughout
the power delivery chain and across an
entire enterprise. These systems offer
an integrated solution to managing new
billing structures, distributed generation,
energy purchasing, energy cost control,
operational and efciency.
Applications that include the meter
typically require additional equipment.
Display and analysis software tools are
almost always used to manage, interpret
and distribute the data measured by a
meter. There are usually a variety of tools
used, and often these tools are connected
using different communications standards
and protocols. In many cases, a meter must
also provide control capabilities and device‐
level data sharing.
Meter Features
Your meter includes an impressive array
of standard features. The following is an
overview of those features.
Measured Parameters
SEM3 meters provide fully bi‐directional,
4‐quadrant, revenue‐accurate or revenue‐
certied energy metering. The following is
a selection of some parameters measured
by these meters.
Energy
The meters provide all common active,
reactive and apparent energy parameters:
kWh, kVARh, and kVAh.
Energy registers can be logged auto-
matically on a programmed schedule by a
supervisory system such as WinPM.Net.
All energy parameters represent the total
for all three phases. Energy readings are
true RMS. Beyond this value, readings roll
over to zero (0).
Real Time Values
SEM3 meter modules provide real time
values, including true RMS, per phase and
total for:
• Voltage and current
• Active power (kW) and reactive power
(kVAR)
• Apparent power (kVA)
• Power factor and frequency
Supported Protocols
You can integrate the meter into various
industry standard networks. Data that the
meter measures can be made available
to other devices using Modbus RTU,
or Modbus/TCP. A digital pulse output
is also available. The controller’s pulse
output is the total kWh for all the single
phase meters whose “Accumulate Energy
Enable” has been enabled in the Branch
Meter Conguration Web Page. You
can also congure the meter to import
data from other devices (i.e. water, gas,
etc.) on these networks using digital
pulse inputs. With these advanced
communications functions, SEM3 system
can be integrated in most existing power
monitoring systems.
Communications Options
The Controller includes a standard
MODBUS RTU/RS-485, BACnet MSTP,
MODBUS TCP, BACnet IP, SNMP, SMTP, and
digital pulse Input/Output.
RS-485 Connections
RS‐485 connections are made via the
captured‐wire connectors on the side of
the controller module. Up to 32 devices
can be connected on a single RS‐485
bus. Each SEM3 controller counts as one
device. Meters below the controller are
dened by registers within the controller.
Use a good quality shielded twisted pair
cable for each RS‐485 bus. The overall
length of the RS‐485 cable connecting
all devices cannot exceed 4000 ft. (1219
m). The RS‐485 bus can be congured in
straight‐line or loop topologies.
Digital I/O Options
SEM3 has two digital pulse inputs built
into the controller. These inputs can be
used for, but are not limited to, bringing
water and gas measurements into the
supervisory system. The digital pulse
inputs are self‐excited digital inputs
capable of detecting a pulse rate of
5 pulses/second. They can be used for
monitoring external contacts or pulse
counting applications. These inputs use
a current sensing technique to monitor
contact status by providing an internal
28 VDC (±4 VDC) supply supply for
self‐excitation.
The SEM3 utilizes the Siemens S7 1200 PLC
for expanded I/O requirements.
The digital pulse output can be
configured as a KY or KYZ pulse output.
External 24 VDC is required. The
output can be configured to show total
system kWh for all the meter modules
monitored by the controller. Individual
meters can be included or excluded from
this total calculation.

General bus wiring considerations
Devices connected on the bus, including
the meter, converter(s) and other
instrumentation, must be wired as follows:
• Connect the shield of each segment of
the cable to ground at one end only.
• Isolate cables as much as possible from
sources of electrical noise.
• Use an intermediate terminal strip to
connect each device to the bus. This
allows for easy removal of a device for
servicing if necessary.
• Install a ¼ Watt termination resistor (RT)
between the (+) and (‐) terminals of the
device at each end point of a straight‐
line bus. The resistor should match the
nominal impedance of the RS‐485 cable,
which is typically 120 ohms (consult the
manufacturer’s documentation for the
cable’s impedance value).
RS-485 Connection Methods to Avoid
Any device connection that causes a
branch in the main RS‐485 bus should
be avoided. This includes star and tee
(T) methods. These wiring methods
cause signal reections that may result
in interference. No more than two cables
should be connected at any connection
point on the RS‐485 bus. This includes
connection points on instruments,
converters, and terminal strips. Following
these guidelines ensures that both star and
tee connections are avoided.

SEM3™ - Embedded Micro Metering Module™ User Manual 9
General bus wiring considerations (cont’d.)
There is an Ethernet port standard on the
SEM3 controller module 10/100BASE‐T port
with an RJ45 modular connector.
The Ethernet port is capable of data rates
up to 100 Mbps and supports Modbus/TCP
and BACnet IP protocol.
Note: You may add up to (4) simultaneous Modbus TCP connections.
Ethernet Connections
Ethernet communications setup
Using the Modbus RTU Protocol
SEM3 meters can act as Modbus Slave
devices, making any real time data
available through the Modicon Modbus
RTU protocol. Modbus Master devices
connected to the meter can access (read)
this data or write data to your meter’s
registers, making device conguration
changes and initiating control actions.
The Factory Modbus Slave Conguration
The meter makes data available to
Modbus Master devices using pre‐
congured Modbus Slave modules.
These modules are linked to other
modules in the meter that provide the
energy, power and demand data. Once
a communications channel is congured
to use Modbus RTU protocol, the data is
available to Modbus Master devices.
Using the Modbus/TCP Protocol
Modbus/TCP is the open Modbus protocol
variant (formerly called MBAP). It denes
the packet structure and connection port
(port 502) for the industry standard TCP/
IP protocol. The structure of Modbus/TCP
is very similar to the Modbus RTU packet
except that it has an extra six‐byte header
and does not use the cyclic redundancy
check (CRC). Modbus/TCP retains the
Modbus RTU limit of 256 bytes to a packet.
Modbus TCP Communications
You can communicate to the meter using
Modbus TCP Connect to socket 502.
Refer to page 106 for more information
on TCP.

Configuring hardware
There are a few steps in conguring the
components of the SEM3 metering system.
Current Transformer (CT) – There is no
setting on the CT for the system. The CT
conguration is available on SEM3 web
pages. The CTs for use in the SEM3 system
are 100 mA output and are self protecting/
shorting so shorting blocks are not
required. Note for multi-pole meters CTs
are required to have the same rating for all
poles. CTs come standard with 6 foot leads
that may be trimmed for neat installation
or extended if required. CT wire length can
retain accuracy up to 500 feet using 18
AWG twisted pair wire (UL 1015, 600v).
Meter Modules – These instructions are
for both levels of accuracy modules.
Each meter module is a single phase
meter and must be connected to the
appropriately sized SEM3 system CT. The
meter module should easily t into the
rack assembly and have audible clicking
when locked into position. The Meter
Rack has the meter module address to the
controller hard coded in the hardware.
Note that meter modules must be mounted
contiguously in the meter racks to be
congured for multi-pole circuit breakers.
Gaps in the rack will not allow multi-pole
meters to be congured as multi-pole
meters. Each module must have the phase
dip switch on the top of the module set to
the phase that the CT is metering phase A,
B, or C (Line 1, 2, or 3 respectively). Note
- Once the meter module is placed into
the meter rack and energized the phase
position will be indicated by a different
color LED for each position. Colors are
orange for phase A (line 1), yellow for
phase B (line 2), green for phase C (line 3).
LED are adjacent to the phase numbers.
The power indication LED also indicates
communications by ashing. CT sizing for
each meter module will be done through
the controller web page conguration.

Global settings
Global settings will be applied across all
the meters in the system. Each meter
can be customized in the Branch meter
conguration screen. The alarms are
for the meters and not meter modules.
Individual phase alarms can only be set
for single pole meters. Alarm delays are
time settings where the meter is in alarm
condition before the alarm ag is set.
This is to prevent momentary conditions
sending alarm ags.
Current setpoints are a percentage of the
CT rating and not the breaker rating. For
example- a 20 amp breaker may have a 50
amp CT applied. For a 80% alarm on the
20 amp breaker the calculation would be
- breaker rating (20 amp) X desired alarm
level (80%) / CT rating (50 amps) = alarm
setting (32%).
These settings should be set rst. Settings
saved will overwrite all other settings. This
should be completed prior to branch meter
conguration.

Pulse Inputs – The SEM3 controller has
(2) pulse inputs available. The Pulse input
module is a highly accurate energy pulser
often used for receiving the pulse inputs
from the water, air, gas, and steam meters.
There are two types of pulse input options
are available:
• Form A (KY) contacts are single-pole,
single throw, normally open contacts.
They have two terminals, which are
open when the energizing force (magnet
or relay solenoid) is NOT present. When
the energizing force is present the
contact will close.
• Form C (KYZ) contacts are single-pole,
double throw contacts. They have
three terminals, a Common, a Normally
Open and a Normally Closed. When
the energizing force is NOT present
the Common terminal is connected to
the Normally Closed terminal. When
energized, the Common terminal
disconnects from the Normally Closed
terminal and connects to the Normally
Open terminal.
The Form A has a Common and a Normally
Closed terminal and would be used on a
standard Closed Loop. The Form C would
function with an Open Loop.

data points will be shown as zero (0) if
the respective meter is not connected
and congured. The csv le shows the
mapping of the analog parameter denoted
by name under the Mapped AI Datapoint
n, where n ranges from 0 – 4, to an analog
input node ID number reference. The csv
le also shows the mapping of the binary
parameter denoted by name under the
Mapped BI Datapoint m, where m ranges
from 0 – 3 to a binary input node ID
number reference.
For example if Mapped AI Datapoint 0
is Volts and AI_ID0 is 0 correspond to
the Meter Id 1, then Meter Id 1 volts are
displayed as values under the node analog
input 0.
The meters for which the BACnet object
mappings are not congured continue to
show-up in the object map csv le, with
the default conguration values. The only
exception is that the phase information
is removed for these meters, when the
user saves the conguration for other
meters. If the user congures all the

Synchronization
The SEM3 controller has features to
enable the recording of system time. The
system time can be stored from the user
input through the System settings page.
The system time will be stored every 15
minutes the controller is operational. So
the last stored system date and time will be

SNMP Support
The SEM3 controller is designed
to respond as a Simple Network
Management Protocol client version 2c.
The client stack is designed using the
software stack derived from DMH software
Inc. When the Modbus Conguration –
TCP/RTU is selected, the SNMP Agent or
client is active. The SNMP client is not
active when the Building Management
system congurations are selected.
The SEM3 controller webpages only allow
the user to congure the IP address of
the SNMP manager. There are no other
conguration related access for the user.
The SNMP manager conguration is stored
from the user input through the System
settings page. The details are located in
the SNMP conguration section under the
System Settings section.
An Internet Assigned Numbers Authority
(IANA) ID of 339 has been assigned
to Siemens and has been used in the

Email
SMTP and Emailing of Logs
In the SEM3 system, the congured Data
and Alarm logs can be emailed to specic
users who have been congured in the
embedded web server. The emails can be
sent immediately to the congured user by
clicking on Send Now button in the Active
Data and Active Alarm Logs pages. The
emails can also be congured to be sent
periodically by conguring the day and
time when the logs are expected to
be emailed.
SMTP Conguration
The SMTP conguration involves
two components.
a. Email conguration
b. User conguration
The email conguration from the SEM3
controller is possible if the correct
settings saved in the System Settings
web page. The details are located in the
Email conguration section under System
Settings section.
The user conguration is setup in the User
prole or user management section. In this
section, the user details are created. The
email address created in the user prole
needs to match the user email address
created for the SMTP server.
Emailing of Logs
The logs are emailed to an email server
which has been congured as a designated
email recipient.

Offline Configuration
The ofine conguration tool allows
the user to create a conguration
le which can be uploaded to the
SEM3 controller webpages through
the “Import Conguration” page.
The ofine conguration tool is a
separate tool external to the SEM3.
The ofine conguration user guide
listed in the Reference section provides
further information regarding the
ofine conguration tool. The section
under “Import conguration” provides
information on how to upload the ofine
created le.
As a part of the ofine conguration tool
implementation, importing of an externally
created le of csv format is allowed. This is
to enable users from importing information
from a from a Siemens COMPAS quoting
conguration tool. The les imported from
the COMPAS or other party tools need to
adhere to the following specications.
csv le Specication
The le format has to be .csv (Windows Comma Separated Value le).
The csv le shall have three parameters ONLY.
The csv le shall not have headers.
The parameters shall be in the following order ONLY (Meter #, # of poles, CT amperage).
The parameters shall not be entered as 0.
- Meter # cannot be left blank or 0.
- # of poles should be in the specic range 1, 2 or 3.
- CT amperage should be in the specic range 50, 125, 250, 400, 600, 800, 1200, 1600 or 2000.
The parameters shall not be entered as out of range.
The parameters shall ONLY have numeric values. (Should not contain 250A for 250 Amps =>
correct notation = 250)
Duplicate entries of meter # shall be ignored and the set of values corresponding to the rst
occurrence will be considered as correct values.
