*BCPM internal circuitry (cables and CTs) are not circuits as dened by UL508A, as they do not extend
beyond the BCPM itself without further safety/re isolation.
The PowerLogic™ BCPME is designed to measure the current, voltage, and
energy consumption of up to 92 circuits (84 branch circuits, two 3-phase mains,
two neutrals), enabling users to monitor two panelboards or an entire data
center PDU with a single product. It increases the board’s current monitoring
capability by combining the functions of two boards into one device. It also
includes Ethernet capability, allowing communication in multiple protocols.
The BCPME consists of a data acquisition module and up to four current sensor
strips, with eight auxiliary inputs. The strips have rows of solid-core CTs and
are mounted on each side of the panel board along the termination points of
each breaker. The conductor passes through the appropriate current sensor
before terminating at the breaker. Each strip transmits the current data to the
data acquisition board. The BCPME measures both current and power for the
mains and branch circuits. The BCPME can easily accommodate different panel
congurations, including any combination of multi-phase breaker positions,
voltage phase mapping, and breaker sizes. To congure the BCPME for
operation, use the Schneider Electric ION Setup conguration software tool.
Get the latest version at https://schneider-electric.box.com/ionsetuplatest.
Data is transmitted via Ethernet with Modbus TCP, BACnet IP, or SNMP
protocol, or via RS-485 with Modbus RTU or BACnet MS/TP protocols. Some
protocols can be used simultaneously, and the Ethernet protocols all support
access by multiple masters. Each data acquisition board requires two Modbus
addresses, one for each set of two current sensor strips and four auxiliary
inputs (two-strip models only require one Modbus address. As a circuit exceeds
the user-dened thresholds, the BCPME activates the event indicators. The
communication interfaces and protocols require some conguration at the time

The BCPME provides several types of measurements that give a
comprehensive view of power consumption for every load on the panel:
• Real-time measurements: A live and up-to-date view of present power
levels and the factors that affect them.
• Demand measurements: Averages of values measured over a
specied time interval. The time interval (typically 15 minutes) can
be set from 10 seconds to more than a day. The demand calculation
can be congured to use single intervals or the sliding average of
up to 6 sub-intervals. Demand measurements are useful for tracking
or graphing load levels over time to correlate with total energy
consumption.
• Historic maximum measurements: These measurements store the
largest value recorded for a specic measurement since the last time
they were cleared. They are useful for identifying peak levels critical to
equipment sizing or demand limits in utility agreements.
• Accumulated energy measurements: Ongoing totals of cumulative
energy used since the last time the value was cleared. Energy values
provide the informational basis for billing, cost allocation, carbon
offset, BTU equivalent calculations, and other applications of overall
energy use.
Branch Circuit Power Meter with Ethernet Communication
Introduction
Z206856-0D
04/2020
• Energy snapshots: Energy totals that only change when the demand
intervals are updated. They are samples of the free-running energy
accumulators at the end of each demand interval, as congured by the
user. These provide energy readings that are easily correlated to the
demand values to simplify the tasks of sub-billing and cost allocation.
• Over-threshold Events (previously referred to as Alarms): Provide a
warning of excessively high or low current on each branch and aux
channel. The user can set two high-level and two low-level thresholds,
and a delay time for latching events. Events are reported as both
non-latched events and latched events. Non-latching events are active
while the current exceeds the threshold, but go inactive if the current
returns to a level within the specic thresholds. Latching events
become active when the current exceeds the threshold for a time
period greater than the specied delay and remain active until they
are cleared remotely. Event status can be polled via any protocol. Via
BACnet, Subscribe_COV can be used to generate event notications.
Via SNMP, they drive SNMP event notications.
Advanced Features - The BCPME supports a number of advanced features.
Some are always active, and others are congured manually via Modbus
register 62017, BACnet object AV164, or SNMP MIB variable “spanels/
.4.1.3833.1.30.1.1.6.3.4.0). For models with 42 channels or more, these
features are congured independently for each panel.
• Logical meter support: The BCPME can be congured to map any set
of 1, 2 or 3 channels that are adjacent in the panel to a logical meter,
referred to in the point map as a logical circuit, that provides accurate
multi-phase measurement totals. Map these logical circuits by writing
the desired logical circuit number into a set of registers/data objects
provided for each branch and aux channel (per panel).
• The channels assigned to each logical circuit must be adjacent in
the panel (usually used for multi-phase breakers), but there are no
limitations on where those adjacent channels are aligned in the panel
(any position where a multi-phase breaker can be installed). This
functionality is always active, but a user selection affects the how the
data can be accessed via Modbus. Measurement data via Modbus
for logical circuits is presented in two ways, arranged either by logical
circuit number (looks more like a collection of individual meters) or by
measurement type (arranged similar to the single-phase data section
of the point map).
• Legacy point map or alternate logical circuit point map: The BCPME
can be congured to select a preferred version of the Modbus
registers in the address range 4000 to 9999. If enabled (default), the
logical circuits by measurement type is active. Otherwise, the legacy
point maps for 2-phase and 3-phase breakers used in BCPM models
with a rmware version earlier than 1.023 is active. The logical circuits
functionality can also be accessed via the “Logical Circuits by Circuit”
section of the point map (address range 10000 to 45000), regardless
of the state of this selection.
• Phase angle measurements: The BCPME measures the phase angle
of every voltage and current input and presents these measurements
(in degrees) in additional data registers/objects. These values are
used to verify that current inputs are assigned to the proper voltage
phases and to help determine how power factor variations are
inuenced by current phase changes vs. harmonic distortion. Phase
angle measurements are instantaneous and always active.
• User CT phase assignment: In the default mode, the BCPME assigns
each channel to the corresponding phase that most 3-phase panels
implement, so that the user does not have worry about it. The user
can opt to replace this self-assignment paradigm with a mode that
Branch Circuit Power Meter with Ethernet Communication
Introduction
allows explicit specication of the phase assignment for each channel.
The explicit assignments set by the user are stored by the BCPME in
non-volatile memory.
• Phase angle reference: The BCPME measures the phase angle of
every current and voltage input. The user can select whether the
phase angles are stated relative to an absolute reference (the phase
angle of voltage input V1) or relative to the voltage phase assigned to
that specic current input channel.
• Demand/snapshot time interval source: The BCPME offers two
mechanisms for driving the demand/snapshot time interval, an interval
timer or an RTC (real-time clock). The legacy mode (default) uses an
interval timer that does not need to be set to an absolute time. When
using the interval timer the demand/snapshot interval can be set from
10 to 32767 seconds (over 9 hours). An alternate mode utilizes an
RTC set to a specic date and time to synchronize the results with a
larger system. The RTC must rst be set in order to run and capture
demand values and energy snapshots. When power is interrupted, the
RTC resets to a default date and time and must be set again in order
to run. When using the RTC, the demand/snapshot interval can be set
from 10 to 3600 seconds (1 hour).

Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
Installation
The protective ground connection on the housing should be used
if the device will not be mounted to a suitably grounded surface. Assure
conductivity to the protective ground.
1. Always use a properly rated voltage sensing device to conrm power is off.
2. Determine where you will mount the BCMPE measurement unit. The
preferred location is inside the enclosure of the panelboard being
monitored. If sufcient space is not available there, then mount the unit in
an appropriate enclosure nearby. Decide whether to mount it vertically or
horizontally. The meter is shipped with the brackets placed on the two sides
for vertical mounting. If desired, you can move the brackets from the sides
to the ends of the housing. Loosen the screws on the sides of the BCPME
that hold the brackets in place (do not fully remove the screws from the
housing). Loosen the screws on the two ends of the housing (do not fully
remove the screws from the housing), and set the brackets into their new
positions. Tighten all screws to 25 in-lb (2.8 N-m).

• While removing or installing panels and covers, assure that
they do not contact an energized bus.
• NEVER bypass external fusing.
• NEVER short the secondary of a potential transformer.
• Before closing covers and doors, carefully inspect the work
area and remove any tools, wire scraps or other objects that
may have been left inside the equipment.
Failure to follow these instructions will result in death or

NOTE: For all steps in this section, when tightening terminals, apply
the correct torque: Aux Inputs: 3.5 to 4.4 in-lb (0.4 to 0.5 N-m); all
other terminals: 4.4 to 5.3 in-lb (0.5 to 0.6 N-m).
1. Wire the (optional) 0.333 V Aux CTs to the BCPME (see Figure 10),

applications, as long as the line-to neutral voltage [especially of the High Leg]
does not exceed 300 Vac (as in North American 120/240 V High Leg Delta
In 3-wire (ungrounded) Delta applications, the BCPME supports these
applications with the following caveats:
Control Power for the meter cannot exceed 277 Vac. In applications
where the L-L voltage is 277 Vac or less (e.g. 208 V line-to-line) it can be
connected to two of the phases being monitored without exceeding the
limit. For higher voltages (e.g. 480 V line-to-line), this must be supplied
from a source that is 277 Vac or less. It could be a separate source or
a transformer can be used to step it down from two of the phases being
measured.
All of the CT inputs (both branches and Aux inputs) are neutral-referenced.
One side of each CT is essentially connected directly to the neutral voltage
input. If this is left oating, the solid-core CT strips, split-core CT adapter
boards and all CTs will oat at the same potential (while the panel is
energized). This does not present a risk to the equipment as long as it is
within 300 V of ground, but should be considered from a safety perspective
in the overall application. The BCPME will provide measurements in this
application with the accuracy specied, with the exception of line-to-neutral

Follow all applicable wiring and termination connection guidelines for the
standard in use. Note that while both the Modbus RTU and BACnet MS/
TP standards identify requirements for RS-485 line polarization/bias and
termination, the value and placement of these resistors varies for each
standard. The BCPME does not implement any RS-485 line polarization/
bias or termination internally. Shield the RS-485 cable using twisted-pair
wire. Use cable that is voltage-rated for the installation. The shield is not
internally connected to Earth Ground. Connect the shield to Earth Ground
somewhere on the RS-485 bus (single point connection only).
6. Connect an Ethernet cable to a local PC. Secure a ferrite lter (included)
around the Ethernet cable to ensure the device meets emission

Installation
If the IP address parameters are not congured for the network, connect a PC
directly and access the GUI from it as follows:
1. Connect a standard Ethernet cable between a PC and BCPME if not
already connected. Secure a ferrite lter (included) around the Ethernet
cable to ensure the device meets emission requirements.
2. Temporarily change the IP address of the PC to a static value on the same
subnet as the BCPME. For example: If the BCPME is set to its factory
default IP address of 192.168.1.24, set the PC to an unused static IP
address on the 192.168.1.xxx subnet (where xxx is any value between 1
and 255, except 24). Set the subnet mask to 255.255.255.0.
a. Open the Control Panel:
b. In the Control Panel, select Network and Sharing Center. In the Sharing
Center, select Change Adapter Settings in the list at the upper left corner.

b. If necessary, change the Subnet Mask by entering the appropriate new
value in the N1_Netmask eld
c. If the BCPME is connected to an Ethernet gateway, enter its IP address
in the Default Gateway eld. This is especially critical if the BCPME will be
used as a BACnet BBMD device.
d. Click the Update IP settings button. The BCPME changes its settings.
e. Click the System Restart button and wait for the BCPME to fully
initialize. The GUI will connect when the BCPME is installed on a network
that matches the settings and the new IP address is entered into a web
browser on a PC properly congured for the network.
Using the GUI to Configure the Communication Protocols
Access the GUI according the instructions in the “Accessing the Graphical User
Interface (GUI)” section.
Branch Circuit Power Meter with Ethernet Communication
Installation
The home screen on the GUI provides elds for conguration of the BCPME.
The BCPME has four primary modes of operation, each of which support a
different combination of protocols. Each option eld has a Submit button to
the right. When changing the value in any eld, click Submit to store the new
value. The GUI prompts the user to restart the system. If multiple values are
changed, it is easiest to submit all changes and restart only once when nished
with the whole screen. To restart, click the System Restart button in the row
at the bottom of the screen. The restart takes several seconds, during which
the server may lose its connection. Messages appear at the top of the screen
indicating current status, but do not perform any actions. Simply allow the tool
to complete the restart cycle.
The rst selection in the GUI is Operating_Mode, which has two choices:
a. Locked: used for all normal product operation. It is provided as a tool
for high-level technical support. The gateway retains its current prole
conguration when powered.
b. Discovery mode (default): deletes proles and rediscovers them when
the device is powered again. The results are the same, unless the prole
conguration is intentionally altered. Prole selection and discovery are
especially important when using BACnet or SNMP protocols. For normal
operation, always use discovery mode.
The second selection in the GUI is Protocol_Mode, used to select the
combination of protocols the product communicates with. The BCPME supports
ve protocols, some of which can operate simultaneously. The table below
shows what protocols are supported in each mode.
Protocol
Mode
1BACnet MS/TPModbus TCPBACnet MS/TP

Protocol
To select a primary protocol mode, enter the corresponding number into
the text eld adjacent to the Primary Protocol option and click the Submit
button to the right of the text eld. A prompt appears at the top of the
screen instructing the user to restart the system. When nished, the screen
refreshes itself with the appropriate elds for the selected mode.
The next GUI selection, in any protocol mode, is the Upstream_Baud rate
selection. If you have selected BACnet MS/TP (mode 1) as the primary protocol
mode, this value sets the MS/TP baud rate. If you have selected modes 2 or 3
as the primary protocol mode, you may not be using the RS-485 interface at all.
If so, this setting can be ignored.
If you have selected BACnet IP, SNMP or Modbus mode, the next selection is
Modbus_Address, which sets the Modbus address(es) for the BCPME when
access with Modbus RTU with the RS-485 serial connection.
The next selection (in BACnet IP, SNMP or Modbus modes) is Modbus_Parity,
which sets the parity of the upstream serial connection. If using Modbus RTU
protocol, set this to match your Modbus master. If not, ignore this eld.
The following sections show the eld selections (with factory default values)
specic to each of the four Protocol_Modes.

1. BACnet MS/TP mode
Z206856-0D

The rst three options are discussed previously.
The DeviceID_Offset parameter is used to assign Device_IDs on power-up
or on restart until they have been overwritten via BACnet. Enter your desired
value here and click submit. The new value is rst used at the next power-up or
system restart. Valid Device_ID numbers range from 1 to 4194303. Since the
numbers assigned during discovery are the sum of the Offset and the Modbus
address (which can be any value from 1 to 247), the Offset values entered in
the GUI must be no larger than 4194057.
The BCPME gateway creates a BACnet virtual router and separate BACnet
devices for each 42-channel meter panel behind this virtual router, allowing
the devices to be discoverable and independently accessed via BACnet, even
if the virtual router is connected by MS/TP, using a single MAC address. To
use this product with MS/TP, the BACnet system must support the discovery
and use of a BACnet router on the MS/TP trunk and any devices beyond it.
This virtual router creates an exclusive BACnet network on which the meter’s
BACnet devices reside. This network must have a BACnet network number
that is different from any other networks in the entire BACnet enterprise. When
multiple BCPME products are added anywhere in the enterprise, each one must
have a unique network number. Failure to set an exclusive value in this eld
causes communication conicts in the BACnet system.
Enter a non-conicting value here and click submit. Valid network numbers
range from 1 to 65534; if other values are entered, the network number defaults
to 5. The new value is rst used at the next power-up or system restart. If using
an external BACnet router to connect the BCPME as an MS/TP device, it is
recommended that the router also be restarted after the BCPME has completed
Branch Circuit Power Meter with Ethernet Communication
Installation
The next eld for the BACnet MS/TP protocol mode is the MSTP_Max_Master,
which allows this value to be set prior to using BACnet software to access the
BCPME. The default value of 127 works regardless of the addresses the MS/TP
network uses, but selecting a lower value may optimize the network. Do not set
this value lower than the highest address on the network. To set this value via
BACnet, write to the Max_Master property of the device object for the BCPME’s
virtual router.
The next eld for the BACnet MS/TP protocol mode is the MSTP_MAC_Addr,
which sets the MAC address for the virtual router. The BCPME panel(s) are
devices on the internal BACnet network and are not directly addressable as
MAC addresses on the MS/TP network.
The nal eld for the BACnet MS/TP mode is RTC_Control, which selects which
protocol (BACnet or Modbus) has write access to the RTC. If 0 (BACnet) is
selected, the RTC is set using the BACnet Time Synchronization service. If
1 (Modbus) is selected, the RTC is set by writing to the appropriate Modbus
registers.
BACnet IP mode uses the same DeviceID_Offset, Virt_Router_Net and RTC_
Control parameters described above for BACnet MS/TP mode. One additional
parameter, BACnet_IP_Port, is used to set the UDP port. Most BACnet systems
use the default port (47808 decimal, 0xBAC0 hex) that is recommended in the

BACnet standard as the only UDP port. Some large systems need to segment
the enterprise and use more than port. If so, enter the number of the port you
need to use to access this device. BACnet IP mode does not use MSTP_Max_
Master or MSTP_MAC_Addr.
BACnet IP mode adds another eld called BBMD_Enable. See the section
BBMD Support for a full description of how to enable and use BBMD support.

SNMP mode uses four unique parameters. SNMP community strings are
used to control access to the device. Whatever values are entered here must
be used in the MIB browser or SNMP access software to communicate with
this device. The Read_Community string is used to enable reading data. The
Write_Community string is used to enable writing data. The Trap_Community
string is used to enable the receipt of event notications.
The last parameter, SNMP_Notif_IP is used to set the IP address of the client
that will be used to receive SNMP event notications for over-threshold events.
Restart the BCPME by using the button at the bottom of the GUI or by cycling
the power. It takes about 30 seconds to initialize completely and be ready for
external communication.
Commission the BCPME for operation using ION Setup software. See the ION
Branch Circuit Power Meter with Ethernet Communication
Commissioning
BACnet conguration uses two default settings that might need to be changed,
depending on the application.
a. Virtual router network ID number. Every logical network segment (IP
subnet, MS/TP trunk, etc.) in an entire system must have a (16-bit) network
ID number that is unique from all other BACnet networks in the enterprise.
The BACnet network administrator assigns this network ID so that no two
ID numbers conict (whether using BACnet/IP or MS/TP). Within each
segment, every device is physically identied by the combination of its 8-bit
MAC address and the 16-bit network ID number.
To support multiple meter panels (panel 1 and panel 2 are separate) with a
single gateway, the BCPME creates a virtual BACnet router that presents
multiple BACnet devices using a single (its own) MS/TP MAC address.
Each BCPME must have its own (internal) network ID, and it creates a
device object for itself and one for each Modbus address discovered.
The factory default network address is 50 (decimal). If that number is
already in use in the system, assign a unique address using the graphical
user interface (GUI) on the built-in web server (this requires an Ethernet
connection to a web browser; see BACnet/IP Setup section for instructions
on changing conguration settings using the GUI). Valid network numbers
range from 1 to 65534; if other values are entered, the network number
defaults to 5.
b. Device_ID Offset. Every BACnet device must have a BACnet
Device_ID number that is unique throughout the entire enterprise. Since
the BCPME presents every Modbus meter as a BACnet device, each
connected meter that has a Modbus address must have a BACnet Device_
ID.
By default, each device discovered receives a Device_ID number that
is the sum of an offset value (default is 50000) and the Modbus address
of the device. If these Device_ID numbers cause a conict with existing
devices in the system, or if the system includes multiple BCPMEs, change
the Device_ID numbers before connecting the BCPME to the system. This
can be managed one of two ways:
i. Connect to the BCPME directly (ofine from the system) with the
devices (meters). After the BCPME discovers the devices and assigns
their default ID numbers, the user can choose new Device_ID values
and write these to each device using BACnet software. Subsequent
discoveries will not overwrite these values with defaults even if the
BCPME is then set to Discovery mode.
ii. Use the GUI on the built-in web server to modify the offset value used
to calculate default Device_IDs in the discovery process (this requires
an Ethernet connection to a web browser; see BACnet/IP Setup section
for instructions on changing conguration settings using the GUI).
The BCPME retains this offset value and uses it to assign Device_ID
numbers every time power is cycled if the BCPME is in Discovery
mode. Valid Device_ID numbers range from 1 to 4194303. Since the
numbers assigned during discovery are the sum of the Offset and
the Modbus address (which can be any value from 1-247), any Offset
values entered in the GUI must be less than 4194057.
25
Branch Circuit Power Meter with Ethernet Communication
Commissioning
The BCPME consists of a BACnet virtual router and one or two 42-channel
branch circuit meters. The BACnet virtual router has its own device object
and an internal BACnet network. The branch circuit monitors have their own
device objects that are logical devices on the network internal to (beneath) the
virtual router. It is critical that the network number of the virtual router’s internal
network be different than any other network number in your entire BACnet
system. The network number is set to 50 at the factory, but can be changed in
the GUI or by writing to the Present_Value of the AV2 data object associated
with that device. Changes to the network number do not take effect until the
BCPME is re-started, either from the GUI or by cycling the power.
The default Device ID of the virtual router is the Device_Offset parameter,
which is set to 5000 at the factory, but can be changed in the GUI or by writing
to Present_Value of the AV1 data object associated with that device. Changes
to the network number do not take affect until the BCPME is re-started, either
from the GUI or by cycling the power. The default Device IDs are numbered to
consecutively follow the Device ID of the virtual router (e.g. if the Device_Offset
parameter is 50000, the virtual router has a Device_ID of 50000, the branch
circuit monitor called Panel 1 has a Device_ID of 50001 and the branch circuit
monitor called Panel 2 (if present) has a Device_ID of 50002.

• Registrations by Foreign Devices
• ISO 10646 (UTF-8) / ANSI X3.4
BBMD Support
All Device_IDs are writable. Once a device’s Object_Identier is overwritten,
changes to the ID Offset no longer affect that Object_Identier, even in
Discovery mode. Make further changes to the value by writing the Object_
Identier property.
The default Object_Name property value of each device object is an
abbreviated name of the meter series discovered with an underscore and the
Modbus address of the meter appended to it. The Object_Name is a writable
property. Once a device’s Object_Name is overwritten, the Object_Name does
not revert to the initial default, even in Discovery mode. Make further changes
to the value by writing the Object_Name property.
The BCPME supports Subscribe_COV, with default COV increment values
assigned as shown in the data object tables. If these values are not appropriate
for a specic application, write them as needed when they are subscribed. On
subsequent power cycles, no subscriptions are active and the COV increments
return to their default values.
With few exceptions, any data values written to AV objects are accepted
(without error) by the data object and passed through to the corresponding
Modbus register. There is no direct indication via the BACnet protocol if invalid
values are rejected. After an invalid value is written to the Present_Value of an
AV, subsequent reads of that property return the new (invalid) value until the
next time the BCPME refreshes its data (this may take several seconds).
When the BCPME is in BACnet IP mode, it can be congured as a BACnet
Broadcast Management Device (BBMD) by entering “BBMD” in the Enable
BBMD Support eld in the GUI, adding devices to a comma separated value
text le named bdt.ini, and loading it onto the device. The example below
shows the syntax required for the bdt.ini le. All lines beginning with two
forward slashes are interpreted as comments. Use exactly one line per device

added, separated by commas (no spaces). The le must include an entry
(line) for each BBMD device in the BAcnet enterprise, including the BCPME
itself. Note: the default gateway address in the network setup must be correct
for BBMD support to operate correctly. Once edited, upload the btd.ini le
to the gateway through the GUI. Click the <Diagnostics and Debugging>
button in the lower right corner of the GUI and follow the folder tree under
Navigation to the following folder: “Schneider Electric BCPM Series Gateway/
Setup/File Transfer.” Select the “General” tab (this is important - using the
wrong tab can overwrite critical les). Click the <Browse> button and select
your bdt.ini le. Then click <Submit>. The GUI quickly indicates “The le was
updated successfully.” Click the <System Restart> button, click <OK> on the
conrmation dialog and wait for the gateway to reinitialize (takes about 30
seconds). BBMD changes are made by uploading a new btd.ini le. After setting
the GUI to enable BBMD support and transferring a new or revised bdt.ini le,
restart the BCPME to load the le. BBMD support can be disabled in the GUI by
entering “-” (a hyphen) in the Enable BBMD Support eld in the GUI.

receiving SNMP V2c event notications can be set via the GUI. MIB les are
available for download from the BCPM Downloads and Documents page at
www.se.com to enable accessing the BCPMSCE from an MIB browser.
The BCPME OID structure organizes the data under two “panels” representing
the two breaker panels that can be monitored by a fully populated BCPME.
Panel 1 corresponds to the branch current sensor strips connected to the
“Panel 1A” and “Panel 1B” connectors and to the data set under Modbus
address 1 or BACnet device identied as Node_1 in the GUI. Panel 2
corresponds to the branch current sensor strips connected to the “Panel 2A”
and “Panel 2B” connectors and to the data set under Modbus address 2 or
BACnet device identied as Node_2 in the GUI.
For each panel, data is arranged under six tree branches.
• The Conguration branch contains all writable conguration
parameters.
• The Alarms branch contains all the event notication traps, the global
event status registers and counters and tables of the event status
indicators.
• The Voltage Inputs branch contains all data measurements pertaining
to the voltage inputs.
• The Auxiliary Inputs branch contains all data measurements
pertaining to the aux inputs other than voltage-related.
• The Branch Inputs branch contains all data measurements to the
branch inputs in table format.
• The Flex Circuits branch contains all data measurements to the logical

• Port numbers can be changed from default values to lower the
predictability of port use.
• Cybersecurity governance – available and up-to-date guidance on
governing the use of information and technology assets in your company.
• Perimeter security – installed devices, and devices that are not in service,
are in an access-controlled or monitored location.
• Emergency power – the control system provides the capability to switch to
and from an emergency power supply without affecting the existing security
state or a documented degraded mode.
• Firmware upgrades – device upgrades are implemented consistently to the
current version of rmware.
• Controls against malware – detection, prevention and recovery controls
to help protect against malware are implemented and combined with
appropriate user awareness.
• Physical network segmentation – the control system provides the capability
to:
• Physically segment control system networks from non-control system
networks.
• Physically segment critical control system networks from non-critical
control system networks.
• Logical isolation of critical networks – the control system provides the
capability to logically and physically isolate critical control system networks
from non-critical control system networks. For example, using VLANs.
• Independence from non-control system networks – the control system
provides network services to control system networks, critical or non-critical,
without a connection to non-control system networks.
• Encrypt protocol transmissions over all external connections using an
encrypted tunnel, TLS wrapper or a similar solution.
• Zone boundary protection – the control system provides the capability to:
• Manage connections through managed interfaces consisting of
appropriate boundary protection devices, such as: proxies, gateways,
are often the source of
unauthorized access by
malicious users.
Secure protocolsModbus TCP, BACnet/IP and
SNMP protocols are unsecure.
The device does not have
the capability to transmit
encrypted data using these
protocols.

• Use an effective architecture, for example, rewalls protecting application
gateways residing in a DMZ.
• Control system boundary protections at any designated alternate
processing sites should provide the same levels of protection as that of
the primary site, for example, data centers.
• No public internet connectivity – access from the control system to the
internet is not recommended. If a remote site connection is needed, for
example, encrypt protocol transmissions.
• Resource availability and redundancy – ability to break the connections
between different network segments or use duplicate devices in response to
an incident.
• Manage communication loads – the control system provides the capability to
manage communication loads to mitigate the effects of information ooding
types of DoS (Denial of Service) events.
• Control system backup – available and up-to-date backups for recovery from
a control system failure.
Address potential risks using these compensating controls:
If you do not change
the default password,
unauthorized access can
occur.
If a malicious user gained
access to your network,
they could intercept

For transmitting data over an
internal network, physically
or logically segment the
network.
For transmitting data over
an external network, encrypt
protocol transmissions over
all external connections using
an encrypted tunnel, TLS
wrapper or a similar solution.
Recommendations to optimize cybersecurity in a protected environment:
• Document and store passwords and usernames in a protected
location.
• Change the default password to help reduce unauthorized access.
Default account settings are often the source of unauthorized access
by malicious users.
• Use complex passwords or passphrases.
• Follow user account management tasks as described by your

Recommendations to optimize cybersecurity in a protected environment:
Firmware upgrades
Secure disposal guidelines
• Harden the device according to your company policies and standards.
• Review assumptions about protected environments and address
potential risks and mitigation strategies. See "Product defense-indepth" for more details.
• Change the default passwords/passcodes. See "Changing passwords"
for more details.
• Change the communication protocol ports from their default values.
This lowers the predictability of port use.
• Disable communication protocol ports when they are not in use. This
reduces the attack surface.
When device rmware is upgraded – security conguration remains the
same until changed, including usernames and passwords/passcodes. It is
recommended to review security conguration after an upgrade to analyze
privileges for new or changed device features and revoke or apply them
according to your company policies and standards.
Use the Secure disposal checklist when disposing a device to help prevent
potential disclosure of data.
