Introduction

Note: The CE mark indicates RoHS2 compliance. Please refer to the CE Declaration of Conformity for additional details.

The PowerLogic™ BCPMSCE Series panelboard monitoring system 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 also includes Ethernet capability, allowing communication in multiple protocols.

The BCPMSCE consists of a data acquisition module, up to 4 current sensor adapter boards and up to 84 split-core current sensors (50 A, 100 A, or 200 A), with eight auxiliary inputs. Each conductor passes through the appropriate current sensor before terminating at the breaker. Each sensor transmits the current data to the data acquisition board. The BCPMSCE measures both current and power for the mains and branch circuits. The BCPMSCE can easily

accommodate different panel congurations, including any combination of

multi-phase breaker positions, voltage phase mapping, and breaker sizes. To

congure the BCPMSCE for operation, use the Schneider Electric ION Setup conguration 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 42 current sensors, and four auxiliary inputs.

When a circuit exceeds the user-dened thresholds, the BCPMSCE activates

the event indicators. The communication interfaces and protocols require some

conguration at the time of installation.

Data Output

The BCPMSCE provides several types of measurements that give a comprehensive view of power consumption for every monitored 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

specied time interval. The time interval (typically 15 minutes) can

be set from 10 seconds to more than a day. The demand calculation

can be congured 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 specic 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.

• 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 congured 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

Branch Circuit Power Meter with Ethernet Communication Introduction

Z206857-0C

04/2020

returns to a level within the specic thresholds. Latching events

become active when the current exceeds the threshold for a time

period greater than the specied 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 notications. Via SNMP, they drive SNMP event notications.

Advanced Features - The BCPMSCE supports a number of advanced features.

Some are always active, and others are congured manually via Modbus

panel1/p1Conguration/p1Setup/p1UserDenedSettings” (OID .1.3.6.1

.4.1.3833.1.30.1.1.6.3.4.0). For models with 42 channels or more, these

features are congured independently for each panel.

• Logical meter support: The BCPMSCE can be congured 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

BCPMSCE can be congured 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

BCPMSCE 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 BCPMSCE 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

inuenced by current phase changes vs. harmonic distortion. Phase

angle measurements are instantaneous and always active.

• User CT phase assignment: In the default mode, the BCPMSCE 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 allows explicit specication of the phase assignment for each

channel. The explicit assignments set by the user are stored by the BCPMSCE in non-volatile memory.

• Phase angle reference: The BCPMSCE 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 specic current input channel.

• Signed power: Users can congure the BCPMSCE to report power as a signed value indicating whether the power is currently being delivered (imported from the grid) or received (exported to the grid) for channels with generation sources or bi-directional (regenerative)

Z206857-0C 04/2020

Branch Circuit Power Meter with Ethernet Communication

loads. When signed power is disabled, the energy accumulators include all energy measured, regardless of direction. When signed power is enabled, the energy accumulators only include all energy delivered (imported from the grid).

• Signed power factor: By default the BCPMSCE reports power factor as an unsigned value. The user can set it to report as a signed value, where the sign indicates whether the current phase angle leads or lags the corresponding voltage phase.

• Demand/snapshot time interval source: The BCPMSCE 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 specic 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. Determine where you will mount the BCMPSCE measurement unit.

The preferred location is inside the enclosure of the panelboard being

monitored. If sufcient 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 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 BCPMSCE 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).

3. Choose a location to mount the adapter boards. If space permits, mount

them in the panelbord being monitored. There are two channel numbering

congurations available, for different applications (see the examples below).

Odd/even numbering is used with panelboards that have odd numbers on one side (usually the left side) and even numbers on the other. Sequential numbering is generally used in other applications, where the panelboard has breakers numbered sequentially or where the branch circuits are used to monitor discrete loads rather than an entire panelboard. Select the

conguration that best ts your application and install the adapter boards

as close as you can to the location where the branch CTs will be installed. Mount the adapter boards using either DIN rail or SNAPTRACK. You can

set the conguration during commissioning by writing to Modbus Register 6

In 3-wire (ungrounded) Delta applications, the BCPMSCE 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.

Z206857-0C 04/2020

Branch Circuit Power Meter with Ethernet Communication

Wiring

All of the CT inputs (both branches and Aux inputs) are neutralreferenced. 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 BCPMSCE will provide measurements in this application with the

accuracy specied, with the exception of line-to-neutral voltages, which

will be calculated and reported, based on a derived virtual neutral voltage, even though they are not relevant.

Corner-grounded delta: the BCPMSCE does not support these applications at any voltage level.

The BCPMSCE supports measurement of all 4-wire Wye, 3-wire split-phase

and 2-wire single phase and congurations that operate between 90 and 300

Vac line-to neutral.

Two sets of connections are provided to simplify daisy-chain connections and enable retention of each wire.

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 BCPMSCE 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).

5. Connect an Ethernet cable to a local PC if not already connected. Secure a

ferrite lter (included) around the Ethernet cable to ensure the device meets emission requirements. Use the PC to congure the gateway (next section

of this document).

Note: 100 to 277 Vac must be applied to control power inputs to supply

power to the gateway during conguration.

The home screen on the GUI provides elds for conguration of the BCPMSCE.

The BCPMSCE 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 prole conguration when powered.

b. Discovery mode (default): deletes proles and rediscovers them when the device is powered again. The results are the same, unless the prole conguration is intentionally altered. Prole 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 BCPMSCE

supports ve protocols, some of which can operate simultaneously. The table

below shows what protocols are supported in each mode.

Protocol Mode Primary Protocol Ethernet Protocol RS-485 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_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) specic to each of the four Protocol_Modes.

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 1-247), the Offset values entered in the GUI must be no larger than 4194057.

The BCPMSCE 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 BCPMSCE 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 conicts in the BACnet system.

Enter a non-conicting 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 BCPMSCE as an MS/TP device, it is recommended that the router also be restarted after the BCPMSCE has completed discovery, when the network number is changed.

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 BCPMSCE. 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 BCPMSCE’s virtual router.

The nal eld is the MSTP_MAC_Addr, which sets the MAC address for the

virtual router. The BCPMSCE panel(s) are devices on the internal BACnet network and are not directly addressable as MAC addresses on the MS/TP network.

2. BACnet IP mode

Branch Circuit Power Meter with Ethernet Communication

Gateway Configuration

BACnet IP mode uses the same DeviceID_Offset and Virt_Router_Net 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.

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 notications.

The last parameter, SNMP_Notif_IP will be used to set the IP address of the

client that used to receive SNMP event notications for over-threshold events.

Restart the BCPMSCE 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 BCPMSCE for operation using ION Setup software. See the

ION Setup Conguration Guide for instructions.

BACnet conguration 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 conict (whether using BACnet/IP or MS/TP). Within each segment, every device is physically identied by the combination of its 8-bit

MAC address and the 16-bit network ID number.

Z206857-0C 04/2020

Branch Circuit Power Meter with Ethernet Communication

BACnet PICS (Protocol Implementation Conformance Statement)

To support multiple meter panels (panel 1 and panel 2 are separate) with a single gateway, the BCPMSCE creates a virtual BACnet router that presents multiple BACnet devices using a single (its own) MS/TP MAC address. Each BCPMSCE 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 conguration 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 BCPMSCE 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 conict with existing

devices in the system, or if the system includes multiple BCPMSCEs, change the Device_ID numbers before connecting the BCPMSCE to the system. This can be managed one of two ways:

i. Connect to the BCPMSCE directly (ofine from the system) with

the devices (meters). After the BCPMSCE 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 BCPMSCE 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 conguration settings using

the GUI). The BCPMSCE retains this offset value and uses it to assign Device_ID numbers every time power is cycled if the BCPMSCE 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.

General BACnet Programming Information

The BCPMSCE 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 BCPMSCE is re-started, either from the GUI or by cycling the power.

Z206857-0C 04/2020

Branch Circuit Power Meter with Ethernet Communication

General BACnet Programming Information

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 BCPMSCE 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.

All Device_IDs are writable. Once a device’s Object_Identier is overwritten, changes to the ID Offset no longer affect that Object_Identier, even in

Discovery mode. Make further changes to the value by writing the Object_

Identier 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 BCPMSCE supports Subscribe_COV, with default COV increment values assigned as shown in the data object tables. If these values are not appropriate

for a specic 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.

BBMD Support

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 BCPMSCE refreshes its data (this may take several seconds).

When the BCPMSCE is in BACnet IP mode, it can be congured as a BACnet

Broadcast Management Device (BBMD) by 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. All lines beginning with two forward slashes are interpreted as comments. Use exactly one line per device,

separated by commas (no spaces). 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 should quickly indicate "The le was

updated successfully." Click the <System Restart> button, click <OK> on the

conrmation dialog and wait for the gateway to reinitialize (takes about 30 seconds). BBMD changes are made by uploading a new btd.ini le.

Branch Circuit Power Meter with Ethernet Communication General SNMP Programming Information

General SNMP Programming Information

The BCPMSCE can be congured to support the SNMP V2c protocol over

Ethernet. The SNMP community string and the IP address for the client

receiving SNMP V2c event notications 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 BCPMSCE OID structure organizes the data under two “panels” representing the two breaker panels that can be monitored by a fully populated BCPMSCE. Panel 1 corresponds to the CT strips connected to the “Panel 1A” and “Panel 1B” connectors and to the data set under Modbus address 1 or

BACnet device identied as Node_1 in the GUI. Panel 2 corresponds to the CT

strips connected to the “Panel 2A” and “Panel 2B” connectors and to the data

set under Modbus address 2 or BACnet device identied as Node_2 in the GUI.

For each panel, data is arranged under six tree branches.

WARNING

POTENTIAL COMPROMISE OF SYSTEM AVAILABILITY, INTEGRITY, AND CONFIDENTIALITY

• Change default passwords to help prevent unauthorized access to device settings and information.

• Disable unused ports/services and default accounts, where possible, to minimize pathways for malicious attacks.

• Place networked devices behind multiple layers of cyber defenses (such as firewalls, network segmentation, and network intrusion detection and protection).

• Use cybersecurity best practices (for example: least privilege, separation of duties) to help prevent unauthorized exposure, loss, modification of data and logs, interruption of services, or unintended operation.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

Use a layered network approach with multiple security and defense controls in your IT and control system to minimize data protection gaps, reduce singlepoints-of-failure and create a strong cybersecurity posture. The more layers of security in your network, the harder it is to breach defenses, take digital assets or cause disruption.

Device security capabilities

Protected environment assumptions

Z206857-0C

04/2020

This section describes the security capabilities available with your device.

User accounts

These security capabilities help enforce authorizations assigned to users, segregation of duties and least privilege:

• User authentication is used to identify and authenticate software processes and devices managing accounts.

• Device conguration and security communications conguration.

Hardening

These security capabilities help prohibit and restrict the use of unnecessary functions, ports, protocols and/or services:

• Least functionality can be applied to prohibit and restrict the use of unnecessary functions, ports, protocols and/or services.

• 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,

routers, rewalls and encrypted tunnels.

Potential risks and compensating controls

Area Issue Risk Compensating controls

User accounts Default account settings

are often the source of unauthorized access by malicious users.

Secure protocols Modbus TCP, BACnet/IP and

SNMP protocols are unsecure.

The device does not have the capability to transmit encrypted data using these protocols.

Branch Circuit Power Meter with Ethernet Communication

• 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 communications.

Change the default password to help reduce unauthorized access.

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.
