E31E Series
Branch Circuit Power Meter with
Ethernet Communication
Product Overview
The E31E Series panelboard monitoring system is designed to measure the current, voltage, and energy
consumption of up to 92 circuits (84 branch circuits, 2 3-phase mains, 2 neutrals), enabling users to monitor two
panelboards or an entire data center PDU with a single product.
*
*The CE mark indicates RoHS2 compliance. Please refer to the CE Declaration of
Conformity for additional details.
The E31E consists of a data acquisition module, up to four current sensor adapter boards, and up to 84 split-core
branch current sensors (50A, 100A, or 200A), with eight auxiliary inputs. Each conductor passes through the
appropriate branch current sensor before terminating at the breaker. Each sensor transmits the current data to
the data acquisition board. The E31E measures both current and power for the mains and branch circuits. The
E31E can easily accommodate different panel configurations, including any combination of multi-phase breaker
positions, voltage phase mapping, and breaker sizes. To configure the E31E for operation, download the NetConfig
configuration software tool and the E3x Commissioning Guide from the Veris website at
www.veris.com /modbus_downloads.
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-defined thresholds, the E31E activates the alarm
indicators. The communication interfaces and protocols require configuration at the time of installation.

Data Outputs
Z206855-0C

TM
The E31E 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 specified time interval. The time interval (typically
15 minutes) can be set from 10 seconds to more than a day. The demand calculation can be configured 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 specific 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 configured 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.
• 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 alarms. Alarms are reported as both non-latched
events and latched events. Non-latching alarms are active while the current exceeds the threshold, but go inactive if
the current returns to a level within the specific thresholds. Latching alarms become active when the current exceeds
the threshold for a time period greater than the specified delay and remain active until they are cleared remotely.
Alarm status can be polled via any protocol. Via BACnet, Subscribe_COV can be used to generate alarm notifications.
Via SNMP, alarms drive SNMP event notifications.
Advanced Features - The E31E supports a number of advanced features. Some are always active, and others are configured
manually via Modbus register 62017, BACnet object AV164, or SNMP MIB variable “spanels/panel1/p1Configuration/p1Setup/
p1UserDefinedSettings” (OID .1.3.6.1 .4.1.40845.1.30.1.1.6.3.4.0). For models with 42 channels or more, these features are
configured independently for each panel.
• Logical meter support: The E31E can be configured 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 E31E can be configured 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 E3x models with a firmware 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 E31E 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 influenced by current
phase changes vs. harmonic distortion. Phase angle measurements are instantaneous and always active.
• User CT phase assignment: In the default mode, the E31E 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 selfassignment paradigm with a mode that allows explicit specification of the phase assignment for each channel. The
explicit assignments set by the user are stored by the E31E in non-volatile memory.
• Phase angle reference: The E31E 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 specific current input channel.
• Signed power: Users can configure the E31E 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) 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).

Data Outputs (cont.)
• Signed power factor: By default the E31E 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 E31E 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 specific date and time to synchronize
the results with a larger system. The RTC must first 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).

Installation
Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
Disconnect power to the panel before beginning the installation.
1. Determine where you will mount the E31E measurement unit. The preferred location is inside the enclosure of the panelboard
being monitored. If sufficient space is not available there, then mount the unit in an appropriate enclosure nearby. Decide
whether to mount the E31E vertically or horizontally. The E31E 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 ends of the E31E that
hold the brackets in place (do not fully remove the screws from the E31E housing). Loosen the screws on the two ends of the
housing (do not fully remove the screws from the E31E housing), and set the brackets into their new positions. Tighten all
screws.
Vertical Mounting
Horizontal Mounting
2. Install the E31E in the panel (hardware not provided). A grounding connection is located on the housing (see below). Use this
stud to ground the device when it is mounted on a nonconductive surface.
The protective ground connection on the housing (item 4 in the Product Diagram) should
be used if the E31E will not be mounted to a suitably grounded surface. Assure conductivity to
the protective ground.

3. Choose a location to mount the adapter boards. If space permits, mount them in the panelboard being monitored. There are
two channel numbering configurations 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 configuration that best fits 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 configuration during commissioning by writing to Modbus
Register 6 or use the free NetConfig configuration software at www.veris.com.
A. DIN Rail: Use the supplied screws to secure the plastic DIN clips to the adapter board. Snap the DIN clips onto the DIN rail.
DIN Option 1: Vertical Mount
DIN Option 2: Horizontal Mount
B. SNAPTRACK: Secure the SNAPTRACK to the mounting surface. Click the adapter board into place.

numbering, use the row designated ODD or EVEN. Odd/even numbering is used with panelboards that have odd numbers on
one side (usually the left side) and even numbers on the other. For applications that require sequential numbering, use the
number row marked SEQ. 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.

120 V/240 V Delta High Leg (where the center tap of one of the three phase-to-phase transformers is grounded): the E3x supports
these 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 configurations).
In 3-wire (ungrounded) Delta applications, the E3x 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-toline) 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 floating, the solid-core CT strips, split-core CT adapter boards and all CTs will float 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 E3x will provide measurements
in this application with the accuracy specified, 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 E3x does not support these applications at any voltage level.
The E3x supports measurement of all 4-wire Wye, 3-wire split-phase and 2-wire single phase and configurations that operate
between 90 and 300 Vac line-to neutral.

4. Mechanically secure the RS-485 cable(s) where they enter the electrical panel.
5. If using Modbus RTU or BACnet MS/TP protocol, connect serial cable(s) from the RS-485 loop to the serial connector on the
E31E. Connect all RS-485 devices in a daisy-chain, and properly terminate the chain. 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 E31E does not implement any RS-485
line polarization/bias or termination internally. For the RS-485 cable, use shielded, twisted-pair wire 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).

Accessing the Graphical User Interface (GUI)
If the E31E IP address parameters are already configured to work on the network and is being accessed from a PC on that same
network, open a web browser and enter the IP address of the E31E into the address/URL field on the browser. Press Enter. The
GUI launches and appears, as shown, in the browser window. Note that the screen captures in this example were taken using
Windows 7; other operating systems will look different.
If the E31E IP address parameters are not configured for the network you can either use a PC-based tool called the Veris Toolbox,
which can be downloaded from the Veris website at www.veris.com (see “Using the Veris Toolbox to Set Up the IP Address for Use
on Your Network” on page 17 or, connect a PC directly and access the GUI as described in the section “Using the GUI to Set Up
the IP Address for Use on Your Network” on page 19.
Using the Veris Toolbox to Set Up the IP Address for Use on Your Network
1. Download the Veris Toolbox software onto a PC from www.Veris.com/BACnet.
2. Extract the software from the zip file.
3. Run the Setup.exe file and follow the installation instructions.
4. Either connect the E31E Ethernet interface to the same network subnet as your PC or connect a cable between them directly.
You will not need to change any network settings on the PC for the Toolbox software to find the E31E.
5. Apply power to the E31E.
6. Launch the Veris Toolbox software. It will discover the E31E, regardless of its IP settings.

in any field, 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 finished 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 first selection in the GUI is Operating_Mode, which has two choices:
1. Locked: used for all normal product operation. It is provided as a tool for high-level technical support. The gateway retains
its current profile configuration when powered.
2. Discovery mode (default): deletes profiles and rediscovers them when the device is powered again. The results are the same,
unless the profile configuration is intentionally altered. Profile 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 E31E supports five protocols, some of which can operate simultaneously. The table below shows which protocols are
supported in each mode.
Protocol Mode
Primary Protocol

To select a primary protocol mode, enter the corresponding number into the text field adjacent to the Primary Protocol option and
click the Submit button to the right of the text field. A prompt appears at the top of the screen instructing the user to restart the
system. When finished, the screen refreshes itself with the appropriate fields 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 E31E 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 field.
The following sections show the field selections (with factory default values) specific to each of the four Protocol_Modes.

1. BACnet MS/TP mode
The first 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 first 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 E31E 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 E31E products are added anywhere in the enterprise, each one must have a unique
network number. Failure to set an exclusive value in this field causes communication conflicts in the BACnet system.
Enter a non-conflicting 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 first used at the next power-up or system restart. If using an external BACnet
router to connect the E31E as an MS/TP device, it is recommended that the router also be restarted after the E31E has completed
discovery, when the network number is changed.
The next field 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 E31E. 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 E31E’s virtual router.
The next field for the BACnet MS/TP protocol mode is the MSTP_MAC_Addr, which sets the MAC address for the virtual router.
The E31E panel(s) are devices on the internal BACnet network and are not directly addressable as MAC addresses on the MS/TP
network.
The final field 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.
2. BACnet IP mode
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 field called BBMD_Enable. See the section “BBMD Support” on page 29 for a full description of
how to enable and use BBMD support.
3. SNMP mode
SNMP mode uses four unique parameters. The SNMP_Community strings are used to control access to the device. Whatever
values are entered here must also 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 notifications.
The last parameter, SNMP_Notif_IP is used to set the IP address of the client that will be used to receive SNMP event notifications,
such as alarms.
Operating the E31E
Restart the E31E 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.

BACnet Network Management – Important Steps to Avoid Conflicts
BACnet configuration 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 conflict (whether using BACnet/IP or MS/TP). Within each
segment, every device is physically identified 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 E31E creates a virtual BACnet
router that presents multiple BACnet devices using a single (its own) MS/TP MAC address. Each E31E 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
“General BACnet Programming Information” on page 29 for instructions on changing configuration 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 E31E 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 conflict with existing devices in the system, or if the system
includes multiple E31E Series, change the Device_ID numbers before connecting the E31E to the system. This can be managed
one of two ways:
i. Connect to the E31E directly (offline from the system) with the devices (meters). After the E31E 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 E31E 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 “General BACnet Programming Information” on page
29 for instructions on changing configuration settings using the GUI). The E31E retains this offset value and uses it to
assign Device_ID numbers every time power is cycled if the E31E 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 to 247), any Offset values entered in the GUI must be less than 4194057.

E31E Series Installation Guide
General BACnet
Programming
Information
TM
The E31E 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 E31E 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 E31E 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_Identifier is overwritten, changes to the ID Offset no longer affect that
Object_Identifier, even in Discovery mode. Make further changes to the value by writing the Object_Identifier 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 E31E supports Subscribe_COV, with default COV increment values assigned as shown in the data object tables. If these values
are not appropriate for a specific 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 E31E refreshes its data (this may take several seconds).
BBMD Support
When the E31E is in BACnet IP mode, it can be configured as a BACnet Broadcast Management Device (BBMD) by entering “BBMD”
in the Enable BBMD Support field in the GUI, adding devices to a comma separated value text file named bdt.ini, and loading it
onto the device. The example below shows the syntax required for the bdt.ini file. All lines beginning with two forward slashes are
interpreted as comments. Use exactly one line per device added, separated by commas (no spaces). The file must include an entry
(line) for each BBMD device in the BACnet enterprise, including the E31E 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 file 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: “Veris E3x Series Gateway/Setup/File Transfer.” Select the “General” tab (this is important - using the wrong
tab can overwrite critical files). Click the <Browse> button and select your bdt.ini file. Then click <Submit>. The GUI quickly
indicates “The file was updated successfully.” Click the <System Restart> button, click <OK> on the confirmation dialog and wait
for the gateway to reinitialize (takes about 30 seconds). BBMD changes are made by uploading a new btd.ini file. After setting the
GUI to enable BBMD support and transferring a new or revised bdt.ini file, restart the E31E to load the file. BBMD support can be
disabled in the GUI by entering “-” (a hyphen) in the Enable BBMD Support field in the GUI.
// Bdt.ini
// The format of this table must be (without the forward slashes - they are comment indicators):
//
//BBMD IP_Address , BBMD port , BBMD subnet Mask

General SNMP
Programming
Information
TM
The E31E can be configured to support the SNMP V2c protocol over Ethernet. The SNMP community string and the IP address for
the client receiving SNMP V2c event notifications can be set via the GUI. MIB files are available for download at
www.veris.com/SNMP.aspx to enable accessing the E31E from an MIB browser.
The E31E OID structure organizes the data under two “panels” representing the two breaker panels that can be monitored by a
fully populated E31E. 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 identified 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 identified as Node_2 in
the GUI.
For each panel, data is arranged under six tree branches.
• The Configuration branch contains all writable configuration parameters.
• The Alarms branch contains all the alarm notification traps, the global alarm status registers and counters and tables
of the alarm 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.
