1 INTRODUCTION

WEB VERSION

There are two meters in the VerifEye® series: the VerifEye 7000 and the VerifEye 7100.
These meters monitor the voltage, current, power, energy, and many other electrical
parameters on single and three-phase electrical systems. A VerifEye meter uses direct
connections to each phase of the voltage and current transformers to monitor each
phase of the current. Information on energy use, demand, power factor, line frequency,
and more are derived from these voltage and current inputs.

The VerifEye meter is not meant to be a standalone energy recorder; rather it is
connected as a slave device to a data logger, Remote Terminal Unit (RTU), or Building
Management host network. The VerifEye meter communication interfaces include
Ethernet (LAN), or RS-485 serial. BACnet MS/TP and Modbus RTU are the two
communication protocols that operate over an RS-485 serial network and BACnet IP and
Modbus TCP are supported over Ethernet. A USB port is also provided as the preferred
connection for on-site configuration and can be run concurrently with an RTU.

1.1 Unpacking the Unit

2 PLANNING FOR FIELD INSTALLATION

WEB VERSION

2.1 Project Manager Aspects

Meter installation often includes coordination between individuals or groups of

people with different responsibilities. Spend a few minutes considering who will
be executing each portion of the installation and what tools are needed at each
stage. Things to consider include determining how to communicate with the
meter, setting address configuration, installing S7 Configuration Utilities, access
to PIN numbers, etc. The more tasks completed before installation the fewer
tasks will be needed in the field. The following section gives an overview of
typical process activities followed by details in the next section.

2.1.1 Configuration & Data Viewing Options

The VerifEye meter has three methods for configuration and data viewing. The

most powerful interface is a Microsoft Windows application (S7 Configuration
Utilities ) that runs on PCs or tablets. S7 Configuration Utilities is encouraged
for complex installations and is required for configuring advanced functions like
alarms. The second interface is the VerifEye Web App and is intended for smart
phones or tablets that can connect over USB, or Ethernet. The third interface is
an optional LCD display which is intended for intermittent end-user observation
and is restricted in capability. The RTU can also be used for configuration
if communication settings are already established. The feature set of each
interface is summarized next.

require that a valid network connection exists between the VerifEye meter and
configuration PC.

Dynamic Host Configuration Protocol (DHCP):

VerifEye meters are shipped in DHCP mode to prevent IP conflicts with other

equipment. The meter is expecting to receive an IP address from a DHCP
service provided by a router, Layer 3 switch, or a server providing DHCP
service. Under this configuration, as long as the VerifEye meter and the host PC
are requesting an IP address from the same DHCP service provider, they will
be able to communicate. Upon powering up, the VerifEye meter will indicate the
IP address on the LCD display (if equipped) or can be found using the Network
Scan function.

3 METER CONFIGURATION

WEB VERSION

Network Scan

Network Scan is a feature for monitoring previously installed and configured

VerifEye meters over an Ethernet network. Network Scan will broadcast a UDP
discovery packet on the same network as the PC running the S7 Configuration
Utilities application. Normally this will be performed on a corporate network
running DHCP. Any VerifEye meter that responds will be displayed in a table
that includes the system description register, IP address, serial number, and
communication configuration.

Highlight the desired meter and select OK, Test or Setup. Note that the

effectiveness of this technique is highly dependent on the configuration of the
PC running S7 Configuration Utilities (which may have more than one network
card) and the network configuration. Rescans can be used to make multiple
attempts to locate a particular meter on busy networks (UDP has no built-in
retry provisions).

Launch Configurator

The final option in the S7 Configuration Utilities Connect to Meter pop-up

window is Launch Configurator. This option allows for the creation of a meter
setup or alarm table for future use without connecting to a meter. After prompting
the user for a meter model, the S7 Configuration Utilities application launches
under a mode with restricted functionality. This mode operates on files only.

3.2.4 Configuring Alarms in S7 Configuration Utilities

The VerifEye power meter has the ability to set alarms for over and under

conditions for voltage and current on any meter channel.

Configuration Input Methods

S7 Configuration Utilities uses dynamic entry for the specification of Alarm

settings. Whichever text entry field is selected becomes the forcing condition
and the other related fields are updated by calculation to reflect a consistent
set of conditions. The text entry fields in grey are Configuration and are NOT
retained by the meter. Only the fields with a black background are stored in the
meters memory or in configuration files

Nominal Values

Entering alarm thresholds based on “percent of nominal” values is helpful

Absolute Values

Entering alarms based on absolute value is a matter of entering the

when alarm conditions are desired to be centered around electrical
components or industry standard conditions. For example, an over current
alarm may be set to 80% of an installed circuit breaker to alert when that
breaker exceeds NEC recommendations.

WEB VERSION

3.2.5 Setting the Real Time Clock

The VerifEye meter includes a Real Time Clock. The clock is used only to time

stamp Interval Data in the log, it is not used for calculation within the meter.
For those customers using the IDR function of the meter, it is helpful (but not
strictly necessary) to set the real time clock so that data records can be uniquely
identified. The time can be set using S7 Configuration Utilities, under the
Advanced Tab, by clicking on the small time icon in the bottom right corner of
the clock.

The clock icon launches the Window Calendar and allows the user to choose

desired date and time. Set Time to Now populates the current time. Click OK to
commit this time to the RTC chip onboard the meter.

Real Time Clock Power Source

The RTC integrated circuit is a stand alone low power circuit within the VerifEye

meter. Time is kept in the absence of a connected external power source (AC or
USB power) by a super capacitor. The capacitor can keep the RTC running over
normal power outages (days to weeks) but is not expected to keep time while
the meter is being stored or shipped.

NOTE: It is recommended that users desiring to use the Interval Data

Recording capability of the VerifEye meter ensure the Real Time Clock is set
as part of the commissioning process.

WEB VERSION

3.2.6 Retrieving Interval Data

The VerifEye meter maintains an internal log of the energy data (Net kWh) for

each channel in the meter. This log is updated every 15 minutes and is always
active. The meter stores 63 days’ worth of 15 minute data in its memory. This
data can be retrieved by users looking to restore gaps in data collection where
RTUs may have been offline or communication has been interrupted. The
Interval Data Recording (IDR) is assessed through S7 Configuration Utilities in
the Advanced menu.

Click Download

By default, the name of the data file will include the Serial Number of the Meter

and the System Description followed by – Datalog.

After clicking OK the entire data path will be displayed

The data log is a Comma Separated Values (CSV) file that can be opened

in Excel or another program. The data will be listed in Chronological Order
according to an internal 32 bit sequence counter. The sequence counter can be
used to merge separate files together if necessary.

listed, choose SINGLE PHASE service from the drop down menu and configure
each channel individually. The three phase loads that are illustrated on the left
and split phase loads on the right are shown as examples only. Elements are
fully interchangeable on the meter.

NOTE: Current and voltage inputs must be installed ‘in phase’ for accurate

readings (e.g. CT1 on Line 1, CT2 on Line 2) Orientation is critical. Ensure
that all CTs are properly oriented with the line and load, as marked.

CAUTION: Failure to install CTs in the correct orientation and on the correct

5 COMMUNICATION & VERIFICATION

WEB VERSION

This section is intended to support the commissioning of the meter by an instrumentation
technician. In many cases, the electrical installation is conducted ahead of the availability
of the RTU or was performed by a different installer. Often the technician is working in
concert with a remote programmer who is confirming the connectivity with a remote host
system. A Digital Multimeter (DMM) can be used to confirm measurements at the board
terminals, if necessary.

WARNING: It is assumed that the meter is now powered up from the line voltage.
ONLY IF THE INTERNAL HIGH VOLTAGE COVER IS INSTALLED is it safe to touch

the meter (including the user buttons) with the top cover removed.

NOTE: Communications settings and real-time data values can be confirmed quickly
using the LCD interface if equipped. When significant setup modifications are
anticipated, a computer interface is recommended.

• Termination Resistors — These are NOT included on the VerifEye meter.

If the VerfiEye meter is at the end of a daisy-chain, then connect a 120-ohm
leaded resistor between the + and – terminal at the connector.

• Bias Resistors — These are NOT included on the VerifEye meter. Bias

resistors are needed if the idle conditions of the bus are in an indeterminant
logic voltage. Bias resistors are usually located at the master node and are
usually 680 ohms for a RS-485 network.

• Network Topology — RS-485 is designed to be implemented as a daisy

chain (series connections) rather than star or cascade topologies.

• Signal Names — Some RS-485 devices use the terminology A/B while

others use +/-. Note that A is (-) and B is (+). Many manufacturers incorrectly
label the terminals.

• Bus Loading — The VerifEye meter is a 1/8th unit load allowing up to 256

like devices in parallel.

5.2 Communication Verification

NOTE: Verification includes confirmation of BOTH the physical interface settings

(Serial or Ethernet) and the protocol (Modbus or BACnet) settings.

The LCD User interface can be used to quickly confirm the settings required for

each combination of interface and protocol. The interface is intuitive and groups
together commonly associated registers. Arrows indicate how to move from
one menu display to the next. The active menu item is indicated by a blinking
character on the LCD. The ENTER button is used to select a property and up /
down buttons are used to select among the values supported by the meter.

NOTE: Changes to the meter configuration are limited to the communication

interface using the LCD. If additional changes (such as CT type) are required
they must be made using a software interface.

5.3 Physical Interface Verification

Serial Setup Verification

In a multidrop serial network, the host data format settings are typically known or

specified and the slave is adjusted to match. In some cases (long wiring runs,
etc.), it may be necessary to experiment in determining the fastest allowable
baud rate for a given wiring configuration by changing BOTH the host and slave
devices. Configurations other than 8N1 are rare and it is advised to use this
configuration for Data Bits, Parity, and Number of Stop bits, if possible.

LAN Ethernet Network Verification

The VerifEye meter communicates using IEEE 802.3 Ethernet connectivity

running at a 10/100 Mbps. Verification of the meter settings over Ethernet
includes ensuring that the IP address of the meter is within a range that allows
communication with a host (if static) or is set for DHCP, allowing the meter to be
assigned an address by a DHCP server as described below.

DHCP

If the VerifEye meter is configured for DHCP when the meter is powered on,

or the Ethernet cable is inserted, the meter is assigned an IP address by the
DHCP server. This address appears on the meter LCD or can be found through
connection with S7 Configuration Utilities or the VerifEye Web App. The IP
address assigned to the meter should be regarded as a temporary address as
the address may change between power cycles making it difficult for the host
system to know how to find the meter on the network. One common approach
is to set the VerifEye for DHCP so that the address can be assigned by a DHCP
server and then change that IP address to static once the connection is made.
VerifEye meters are set to use DHCP as a default setting to facilitate
this approach.

Static IP

If the VerifEye meter is set to a static IP then its address should be assigned by

an IT department to avoid multiple devices on the same network. This scheme is
usually used when an RTU is expecting to find the meter at a specific
IP address.

5.4 Protocol Verification

The network protocol is typically specified as part of the installation. BACnet MS/

TP and Modbus RTU are the two communication protocols that operate over an
RS-485 serial network and BACnet IP and Modbus TCP are the protocols over
Ethernet. Each combination of interface and protocol require specific registers
settings described below. The scope of this section is to use either the LCD
interface or software tools to quickly confirm or change settings to match an
existing specification. Further information and optimization tips are covered in
the section on RTU programming.

5 COMMUNICATION & VERIFICATION

WEB VERSION

5.5 Modbus Settings

Modbus RTU Settings

Device Address: In a Modbus network each device must be assigned a unique

slave address. Valid Modbus addresses are 1-240 (the VerifEye 48 channel
meter requires 15 addresses beyond Element A). The slave address of the
power meter sets the register address for Element A. Adjacent elements B, C, D,
etc. are accessed by incrementing the slave address by 1. The slave address
of the VerifEye meter needs to be set to match the address expected by the
RTU and is normally part of the network specification. The default address for
element A is 1.

Modbus TCP Settings

Modbus Port: The VerifEye meter uses the industry standard Port 502 for

Modbus. This port number can be changed, although this is considered an
advanced setting and should be left at 502 unless this generates a conflict
on the host system. The port number can only be changed through the S7
Configuration Utilities software interface.

5.6 BACnet Settings

BACnet Device ID: In a BACnet network, each device must be assigned

a unique Device ID and is common to BACnet MS/TP and BACnet IP
protocols. Besides the standard ability to change this from a BACnet explorer

tool it may be changed via S7 Configuration Utilities, VerifEye Web App, or LCD.

BACnet MSTP

Device Address: VerifEye meters are Master devices and as such must use

MS/TP addresses in the range from 0-127. This address must be unique on
the network.

Max Masters: The default setting is 127 and does not usually need to

be changed.

Max Info Frame: The default setting is 1 and does not usually need to

be changed.

BACnet IP

BACnet Port: The BACnet default port is 47808 and does not usually need to

be changed.

BBMD: The BACnet/IP Broadcast Management Device is set to 0.0.0.0 at

default and can be changed through a software tool to allow discovery
across networks.

5.7 Pulse Inputs

Series 7000/7100 meters are equipped with 2 pulse inputs.

Pulse counting supports accumulation of consumption data
from any external meter using a dry contact (Form A Relay)
or open collector outputs. The pulse inputs are compatible
with “low speed” meters. The pulse duration must exceed
50mS in both the logic low and high state allowing for a
maximum input frequency of 10 Hz.

Pulse scaling, resetting and accumulated values are accessed through registers

and are “system” in scope.

Refer to the register list or S7 Configuration Utilities for more information.

5.8 Alarms (SPDT)

The VerifEye meter supports user-configurable alarms for over-current, under-

current, over-voltage, and under-voltage. S7 Configuration Utilities helps users
set these values by allowing for values to be entered using direct entry mode or
specifying the limits as a percentage of nominal.

Alarm persistence settings are used to allow for temporary conditions, such as a

motor starting, that are beyond trigger limits.

EXAMPLE: In the case of meter upset from ESD events, short persistence

settings may lead to false alarm triggers. When any alarm condition has been
satisfied throughout the persistence interval, the VerifEye trips the Master Alarm
relay, which is an electromechanical relay on the PCB.

Once tripped, the relay can only be reset by clearing the alarm through Modbus

register/ BACnet object 2451.

The Master Alarm relay can be hard wired to an interrupt or polling circuit in a

host system allowing for a more rapid response than the data polling frequency,
if desired. The status of each alarm is determined by reading status registers.

Refer to the register list or S7 Configuration Utilities for more information.

NOTE: The Master Alarm relay is intended for low voltage DC connections.

The user must protect the switch from over-current conditions when closed.

5.9 12 Volt Auxillary Power

The VerifEye meter provides an auxiliary 12 volt output that is derived from an

auxiliary winding on the VerifEye meter’s line-connected power supply. The 12
volt supply voltage is unregulated but protected by a self-resetting fuse. The
purpose of the supply is to power external radio equipment or provide supply
voltage for analog sensors, such as 4-20 mA current loop devices. If full-rated
current is drawn from this terminal, the minimum operating voltage of the L1-L2
power supply is 100 VAC.

5.10 Access Restriction Limitations

If security levels have been set up in the meter, no data is accessible through

the LCD user interface or VerifEye Web App without entering the
PIN credentials.

NOTE: Protocols such as Modbus DO NOT SUPPORT ANY LEVEL OF security

such that any network traffic acting as a master can retrieve and write data from
the registers. Generally, this will require knowledge of the IP address or slave ID
and the register list which discourages casual intrusion.

5.11 Security PIN Protection

VerifEye meters have two levels of PIN protection that users can choose to

assign for restricting access to meter information. The PIN logic is described in
the figure below. The default user entry (on power up or time-out) is 0000 which
satisfies both the Read Only and the Read / Write default register settings.

Using the Permission Registers

The VerifEye meter uses both a Read Only register and a Read/Write register

to compare against user entries from the LCD keypad or VerifEye Web App
form entry. Both internal permission registers have a default value of [0000].
A consequence of this is that both PIN registers need to be configured (i.e.
changed from defaults) to implement a read only PIN, otherwise the situation
may occur where a user intends to restrict access to Read Only by setting only
this PIN unaware of the fact that the default PIN still matches the criteria for
Read/Write which will accidentaly promote the user. S7 Configuration Utilities
and the VerifEye Web App disallow this condition, but remote programmers
using direct register access may create this condition.

5 COMMUNICATION & VERIFICATION

WEB VERSION

Read Only Permission Register

Configuring the meter for a Read Only user allows data or configuration items

to be viewed, but not changed. This level of authorization might be appropriate
for general end-users such as building owners who may not be aware of the
details of the installation. It is recommended to use S7 Configuration Utilities to
configure permissions, although it is also possible to set up a Read Only PIN
using the VerifEye Web App if a Read/Write PIN has already been entered
(either through the LCD or the VerifEyev Web App itself).

Read/Write Permission Register

Read/Write permissions allow users to read and write configuration items and to

reset the PINs. This level of authorization will be required by any technician or
user who needs the ability to correct setup errors in the meter. The default PINs
(0000) allow new users to reset the Read/Write PIN from either the VerifEye web
app or S7 configuration utilities. Permissions cannot be set through the
LCD interface.

Reading PINs Over Modus or BACnet

S7 Configuration Utilities can be used to directly report the Read Only and

Read/Write PINS under the Advanced Tab (passwords). The value reported by

S7 Configuration Utilities is the value as entered in the web page or
LCD interface.

PINs are also accessible as registers, but are encoded so that reading the value

of the register through an RTU does not inform a user what the password is.
This feature allows Leviton Manufacturing to support looking up forgotten PINs,
if network access is available.

S7 Configuration Utilities - Unrestricted Access

The S7 Configuration Utilities software tool can be used to read & write

configuration information to the meter without entering credentials.

NOTE: S7 Configuration Utilities is the recommended tool for setting up access

restrictions. It allows users to test the function of the PINs without locking
themselves out from the ability to change the PIN.

5.12 Verification of Installation

Once the VerifEye meter is configured and communicating with the RTU, it is a

good idea to perform some simple checks to ensure that all the CTs are on the
correct voltage phases and that the CTs are facing the correct direction. The
following are recommendations that work for typical installations. Special circuit
conditions, like unloaded motors, may indicate an installation error when none
exists. A Digital Multimeter (DMM) can be used to confirm these cases.

5.12.1 Installation Phase Verification

The VerifEye meter includes a PhaseChek™ algorithm that identifies any

element that the meter suspects may be incorrectly phased (i.e., the CT is
associated with the wrong voltage source or is physically on the wrong wire)
based on power factors below 0.55. This feature is accessed using the LCD
interface by navigating to [VERIFY INSTALLATION] and pressing [ENTER].
The LCD display will list the elements having at least one channel with a low
power factor.

CHECK ELEMENTS

A EF

Use the navigation buttons to highlight a specific element and hit enter or just

hit enter and move from element to element using the <- / -> keys. Within each
element (identified on the top line of the display) the status of each channel is
identified as good (PF > 0.55) or bad (PF < 0.55).

ELEMENT F

CH1 Good

CH2 Bad

CH3 Bad

Two “Bad” channels are often an indication that two CTs are inadvertently

swapped. When the power factor for all enabled channels is greater than 0.55,
the meter reports:

CHECK ELEMENTS

ALL CHANNELS GOOD

NOTE: PhaseChek is only applied for elements that are enabled. [VIEW METER

SETUP] on the LCD screen can be used to ensure that all intended elements
are active. PhaseChek is advisory only. It is possible that the power factor for a
particular load is truly less than 0.55, as may be observed in a free
running motor.

The S7 Configuration Utilities and the VerifEye Web App run PhaseChek

continuously on all enabled elements and report low power factor in the real time
values table by turning the text RED or by a using a red indicator.

5 COMMUNICATION & VERIFICATION

WEB VERSION

5.12.2 Phase Checking by Phasor Plot

When a CT is installed on the incorrect phase, the indicated current vector is

pointing either 180 degrees away (a split phase system) or 120 degrees away
(a three-phase system) from the true displacement angle. In the latter case, this
usually causes a significant decrease in the reported power factor, even if the CT
is also on backwards. When the absolute displacement power factor of a load
is below 0.55 (an angle greater than 57 degrees between voltage and current),
the VerifEye meter will flag it as a phasing error. S7 Configuration Utilities has a
Phasor Plot feature that can be used to study the voltage and current vectors of
a given meter element.

5.12.3 CT Orientation Check

The VerifEye meter reports power and energy in each electrical quadrant under

a different register. When CTs are installed backwards, the indicated current
vector is oriented 180 degrees away from the true displacement angle. In
accordance with standard definitions, the Wattage and VARs of the effected
channel report with a sign opposite from what is expected. Often this means that
the import registers will be reading zero while the export registers are showing
a value.

NOTE: Backward CTs have no impact on the amplitude of the power factor.

A moderate power factor (>0.7) in concert with a negative power is a clue that
the CT is on backwards, but is on the correct phase. If a CT is discovered to be
on backwards after the installation is complete, the direction of the CT can be
reversed through a user configuration register designed for this purpose, called
the Flipper, located at 2226, 2234, and 2235 or use the meter setup within S7
Configuration Utilities’ meter setup.

5.13 Power Factor Convention

Power Factor is the ratio of a signed number (true power) and an unsigned

number (apparent power). This discrepancy has led to some customer
confusion. The VerifEye meter allows users to select between two conventions
(ANSI & IEEE).
In the IEEE convention the sign of PF follows the sign of power itself. In the
ANSI convention a [+] PF indicates a lagging current (inductive load) while a
[–] PF indicates a leading current (capacitive load). The sign relationships are
shown below for these conventions in each electrical quadrant.

In many circumstances users are interested in the harmonic content of current.

In cases where the voltage is very sinusoidial, the T measurement is a good
estimate of both power and current. However, if the voltage waveform is
distorted, the reported T in power can be misleading. S7 Configuration Utilities
can provide additional analysis of harmonic content in voltage and current by
sampling the VerifEye raw data and performing digital signal processing on the
signal. Using this method, the individual harmonics levels can be observed. The
results are presented in a bar graph.

5.15 Pre-Processing Aids

The meter has several registers that can aid in pre-processing or post-

processing data that otherwise may need seconday operations.

Snap Thresholds

The signal to noise ratio of the meter is above 80 db at full scale (1 part in

10,000). When the signal amplitude becomes so small that it is indistinguishable
from noise it is often better to record 0 than a small random value. Snap
Threshold registers (Advanced tab in S7 Configuration Utilities) tell the meter
when to record 0 instead of the measurement result. The factory defaults for
CT’s are expressed in percent and have a default value of 0.04% Full Scale. The
voltage thresholds are in absolute value, the recommended minimum voltage
is 1.0 volt

Multipliers

The meter has registers that allow potential transformers and series current

transformers to be used with the VerifEye meter. These registers allow for
transformer winding ratios or other scaling adjustments to be included in the
meter processing to eliminate post process scaling. Adjustments for voltage
are global to the meter while CT’s can be adjusted on a channel by channel
basis. The multiplier is a floating-point number and can also be used for post
installation calibration if desired. Default values are 1.0

CT Phase Shifts

Current transformers like all other transformers experience a small magnetizing

current that is out of phase with the measurement current. Phase shift registers
are available on a per channel basis and allow corrections of +/- 3 degrees. S7
Configuration Utilities loads the default phase shift for the CT types available in
the picker list. If no phase shift information is available then enter the accuracy
class in degrees (i.e. 1% = 1.0 degree).

Demand

VerifEye meters keep track of electrical demand using a 15 minute sliding

window. The Peak Demand and Present Demand registers contain the highest
average power consumption in any 15 minute interval and the average power
consumption in the last 15 minute interval respectively. The Clear Peak Demand
register is used to reset the peak demand detector.

6 RTU PROGRAMMING & SCRIPTING

WEB VERSION

This section is intended for the programmer of the RTU or host system and includes
details about meter and element addressing, register locations, data formats and
protocol examples.

6.1 Register Organization

The VerifEye meter communicates through the reading and writing of registers.

Registers are organized into functional groups and are compliant with the
SunSpec Modbus interface model.

• SunSpec Common Registers

• SunSpec TCP Network Stack Registers

• SunSpec Serial Interface Registers

• SunSpec Energy Meter

The complete register set is included as an Excel file on the supplied thumb

drive or at:

https://www.leviton.com and go to the S7000/7100 product page's

Support/Downloads section.

6.2 Element vs. System Scope

Element

The term “element” is used in two contexts. Physically the term Element is

used to describe groups of three channel sections identified by alphabetic letter
on the silk screen of the PCBA (ie A,B,C,D). In a three phase power system
these correspond to electric circuits. Logically the term Element describes the
scope of a data item, register or point (Modbus register or BACnet object). Each
Element based point is accessed by choosing the appropriate Modbus address,
BACnet object range, or BACnet structured view. Elements in turn have points
that refer to individual channels or to SUMS or AVERAGES of those channels.
Registers that contain data inclusive of more than one channel are identified as
being either SUMS or AVERAGES of the enabled channels within an element.
In a BACnet structured view an Element represents a level of organization for
related points.

Channel

Channels are identified on the circuit board as CH1, CH2, or CH3 and represent

physical CT inputs. In three phase system configurations, these correspond to a
current load on a corresponding line voltage. In single phase configurations, they
are just used to identify a CT location. Registers providing data for an individual
channel are also described as elements in their scope as a unique value exists
for each Slave Address or BACnet object instance.

System

The term “System” refers to registers defining the characteristics of the entire

circuit board. System registers report the same value independent of the slave
address. Under BACnet structured view the system points are
grouped together.

6.3 Configuring Element and Channel Register for Service Types

The S7 Configuration Utilities software enforces all element configurations to

form a valid electrical system. Configurations performed by remote systems
may produce unexpected results if configurations are internally inconsistent.
The following tables document how to configure element and channel registers
for each service type. Every register should be explicitly written.

RED Text indicates Required Values, PURPLE Text indicates Suggested

Defaults, if this data is not known.

6.5 Modbus Protocol Commands

If configured for Modbus, the Verifeye networked power meter family follows the

Modbus RTU protocol and supports the following command set.

Supported Modbus Commands

Command Name Command Number

Read Holding Registers

Write Single Register 06 Used to write a single holding register to a VerifEye meter

Report Slave ID 11 Used to read information from the identified VerifEye meter

Slave Address

For Modbus/TCP the base slave address (or unit address as the Modbus TCP

spec. calls it) is fixed at 1.

Refer to the section Serial Protocols for additional information on setting the

Slave Address and finding the address of a specific meter element.

Modbus String Entry

Registers that are identified as strings are handled uniquely by the VerifEye

power meter. Each register in the string block must be written to sequentially
without interruption either by using a write multiple command or by sending
single register commands back to back. The final character in the string MUST
be a NUL character (ASCII 0). The meter will process the entire string only
if these two conditions are met, otherwise the data is ignored. This special
processing has been implemented to protect partial updates for
network settings.

Commands Requiring a Processor Reset

Register manipulation of communication protocols or addressing require that

the VerifEye meter performs a soft reset in order to take effect. Register 2100
can receive a user command to facilitate this process. BACnet users write a [1]
and Modbus users write [1234] to effect a soft reset. The meter reboot time is
approximately 10 seconds.

See the Modbus examples document on the Leviton Manufacturing web

site or included with your electronic documentation for additional support on
programming Modbus.

6.6 BACnet

Building Automation and Control Network (BACnet) protocol was developed under

the auspices of the American Society of Heating, Refrigerating and Air-Conditioning
Engineers (ASHRAE) and is recognized as an American National, European, and
ISO global standard.

BACnet Device ID: All device IDs on a BACnet network must be unique. Refer to

the section Serial Protocols and refer to the Register List for additional information.

Serial: The VerifEye Serial version supports writable max_master, MS/TP address,

max_info_frames properties in the device object for MS/TP networks. For best
network performance, the max_master should be set to the highest MS/TP MAC
address on the network. The MS/TP address (object 1069) must be unique on the
MS/TP network. The max_info_frames does not need to be changed in
most installations.

Ethernet: Ethernet versions can register as Foreign Devices to a BBMD. BBMD

stand for BACnet/IP Broadcast Management Device. The BBMD IP address can be
set from S7 Configuration Utilities or through character string object 2264. A value of

0.0.0.0 disables foreign device registration. This process requires a processor
soft reset.

BACnet Structured View

The VerifEye meter supports the Structured View (SV) object container. If this option

is supported in the BACnet exploring tool, objects will be grouped logically into
elements which can be named to reflect electrical or physical locations, followed by
system objects, as shown below for a VerifEye 12 having elements A-D.

Within each element, Structured View lists the BACnet objects by Object Type
and then by numeric number as shown below. In addition objects for elements are
grouped in a “hotel room” scheme. That is Element A (and system objects) have a
range from 0-9999, Element B 10000-19999, Element C 20000-29999, to Element P
on the VerifEye 48 circuit meter 150000-15999. Some BACnet explorer tools have
additional sorting capabilities.
