Overview
and Specifications
IQ 250/260 Overview
The IQ 250/260 is a multifunction power and energy meter designed to be
used in electrical substations, panel boards, and as a primary revenue
meter, due to its high performance measurement capability. The unit provides multifunction measurement of all electrical parameters and makes
the data available in multiple formats via display, communication systems,
and through analog signal transmission. In addition, the IQ 250/260 meter
has optional data logging capability.
The IQ 250/260 meter is designed with advanced meaurement capabilities, allowing it to
achieve high performance accuracy. It is specified as a 0.2% class energy meter for billing
applications as well as a highly accurate panel indication meter.
The IQ 250/260 provides additional capabilities, including standard RS485, Modbus and DNP
3.0 Protocols, and Option cards that can be added at any time.
Figure 2.1: IQ 250/260 Meter
Features of the IQ 250/260 include:
• 0.2% Class revenue certifiable energy and demand metering
• Meets ANSI C12.20 (0.2%) and IEC 687 (0.2%) classes
• Multifunction measurement including voltage, current, power, frequency, energy, power
factor, etc.
• Power quality measurements (%THD and Alarm Limits) IQ 260
• Optional 128 kiloBytes of memory for data logging - IQ 250/260 with L option
• Percentage of Load Bar for analog meter reading
• Easy to use faceplate programming
• RS485 communication
• Optional I/O Cards - field upgradeable without removing installed meter
In addition to the IQ 250/260M - meter with integral
display/transducer configuration, an IQ 250/260T transducer
configuration is available. The IQ 250/260T is a digital transducer
only unit (without a display), providing RS485 communication
via Modbus RTU, Modbus ASCII or DNP 3.0 protocols. The IQ 250/260T is designed to install using DIN Rail
mounting. (See Chapter 3 of this manual for IQ 250/260T
mounting information.) www.eaton.com

Overview and Specifications
IQ 250/260 Meter
Voltage and Current Inputs
Universal Voltage Inputs
Voltage Inputs allow measurement up to 480VAC (Phase to Reference) and 600VAC (Phase to
Phase). This insures proper meter safety when wiring directly to high voltage systems. One unit will
perform to specification on 69 Volt, 120 Volt, 230 Volt, 277 Volt, and 347 Volt power systems.
NOTE: Higher voltages require the use of potential transformers (PTs).
Current Inputs
The unit supports a 5 Amp or a 1 Amp secondary for current measurements.
NOTE: The secondary current must be specified and ordered with the meter.
The IQ 250/260 Current Inputs use a unique dual input method:
Method 1: CT Pass Through
The CT passes directly through the meter without any physical termination on the meter. This
insures that the meter cannot be a point of failure on the CT circuit. This is preferable for utility
users when sharing relay class CTs. No Burden is added to the secondary CT circuit.
Method 2: Current “Gills”
This unit additionally provides ultra-rugged Termination Pass Through Bars that allow CT leads to be
terminated on the meter. This, too, eliminates any possible point of failure at the meter. This is a
preferred technique for insuring that relay class CT integrity is not compromised (the CT will not
open in a fault condition). 2-2

Overview and Specifications
Utility Peak Demand
The IQ 250/260 provides user-configured Fixed Window or Sliding Window Demand modes. This
feature enables you to set up a customized Demand profile. Fixed Window Demand mode
records the average demand for time intervals that you define (usually 5, 15 or 30 minutes). Sliding Window Demand mode functions like multiple, overlapping Fixed Window Demands. You
define the subintervals at which an average of demand is calculated. An example of Sliding
Window Demand mode would be a 15-minute Demand block using 5-minute subintervals, thus
providing a new demand reading every 5 minutes, based on the last 15 minutes.
Utility Demand Features can be used to calculate Watt, VAR, VA and PF readings. Voltage provides
an Instantaneous Max and Min reading which displays the highest surge and lowest sag seen by the
meter. All other parameters offer Max and Min capability over the selectable averaging period. Specifications

Considerations When Installing Meters
Installation of the IQ 250/260 Meter must be performed only by qualified personnel who follow
standard safety precautions during all procedures. Those personnel should have appropriate
training and experience with high voltage devices. Appropriate safety gloves, safety glasses and
protective clothing is recommended.
During normal operation of the IQ 250/260 Meter, dangerous voltages flow through many parts of the meter, including: Terminals and any connected CTs (Current Transformers) and PTs (Potential Transformers), all I/O Modules
(Inputs and Outputs) and their circuits. All Primary and Secondary circuits can, at times, produce lethal voltages
and currents. Avoid contact with any current-carrying surfaces.
Do not use the meter or any I/O Output Device for primary protection or in an energy-limiting capacity. The meter
can only be used as secondary protection. Do not use the meter for applications where failure of the meter may
cause harm or death. Do not use the meter for any application where there may be a risk of fire.
All meter terminals should be inaccessible after installation.
Do not apply more than the maximum voltage the meter or any attached device can withstand. Refer to meter and/
or device labels and to the Specifications for all devices before applying voltages. Do not HIPOT/Dielectric test any
Outputs, Inputs or Communications terminals.
Eaton recommends the use of Shorting Blocks and Fuses for voltage leads and power supply to prevent hazardous voltage conditions or damage to CTs, if the meter needs to be removed from service. CT grounding is optional.
NOTES:
• IF THE EQUIPMENT IS USED IN A MANNER NOT SPECIFIED BY THE MANUFACTURER, THE
PROTECTION PROVIDED BY THE EQUIPMENT MAY BE IMPAIRED.
• THERE IS NO REQUIRED PREVENTIVE MAINTENANCE OR INSPECTION NECESSARY FOR
SAFETY. HOWEVER, ANY REPAIR OR MAINTENANCE SHOULD BE PERFORMED BY THE
FACTORY.
DISCONNECT DEVICE: The following part is considered the equipment disconnect device.
A SWITCH OR CIRCUIT-BREAKER SHALL BE INCLUDED IN THE END-USE
EQUIPMENT OR BUILDING INSTALLATION. THE SWITCH SHALL BE IN CLOSE
PROXIMITY TO THE EQUIPMENT AND WITHIN EASY REACH OF THE OPERATOR. THE
SWITCH SHALL BE MARKED AS THE DISCONNECTING DEVICE FOR THE EQUIPMENT.

CT Leads Terminated to Meter
The IQ 250/260 is designed to have Current Inputs wired in one of three ways. Diagram 4.1 shows the most typical
connection where CT Leads are terminated to the meter at the Current Gills. This connection uses Nickel-Plated
Brass Studs (Current Gills) with screws at each end. This connection allows the CT wires to be terminated using
either an “O” or a “U” lug. Tighten the screws with a #2 Phillips screwdriver.
Other current connections are shown in Figures 4.2 and 4.3. Voltage and RS485/KYZ Connection is shown in
Figure 4.4.

CT Leads Pass Through (No Meter Termination)
The second method allows the CT wires to pass through the CT Inputs without terminating at the meter. In this
case, remove the Current Gills and place the CT wire directly through the CT opening. The opening will accomodate up to 0.177” / 4.5mm maximum diameter CT wire.

IQ 250/260 485 Connection
Figure 5.2: 2-wire RS485 Connection
NOTES:
For All RS485 Connections:
• Use a shielded twisted pair cable 22 AWG (0.33 mm2) or thicker, and ground the shield, preferably at one location
only.
• Establish point-to-point configurations for each device on a RS485 bus: connect (+) terminals to (+) terminals;
connect (-) terminals to (-) terminals.
• You may connect up to 31 meters on a single bus using RS485. Before assembling the bus, each meter must have
a unique address: refer to Chapter 8 for instructions.
• Protect cables from sources of electrical noise.
• Avoid both “Star” and “Tee” connections (see Figure 5.4).
• No more than two cables should be connected at any one point on an RS485 network, whether the connections
are for devices, converters, or terminal strips.
• Include all segments when calculating the total cable length of a network. If you are not using an RS485 repeater,
the maximum length for cable connecting all devices is 4000 feet (1219.20 meters).
• Connect shield to RS485 Master and individual devices as shown in Figure 5.3. You may also connect the shield
to earth-ground at one point.
• Termination Resistors (RT) may be needed on both ends for longer length transmission lines. However, since
the meter has some level of termination internally, Termination Resistors may not be needed. When they are used,
the value of the Termination Resistors is determined by the electrical parameters of the cable.

Performing Watt-Hour Accuracy Testing (Verification)
To be certified for revenue metering, power providers
and utility companies must verify that the billing energy
meter performs to the stated accuracy. To confirm the
meter’s performance and calibration, power providers use
field test standards to ensure that the unit’s energy
measurements are correct. Since the IQ 250/260 is a
traceable revenue meter, it contains a utility grade test pulse
that can be used to gate an accuracy standard. This is an
essential feature required of all billing grade meters.

Current and Potential Transformers are used mainly for the following reasons:
• To insulate, and as a result isolate, the meter from high-voltage circuits
• To change the primary voltage and current to standard values and sizes that the meter can measure.
The CT and PT transformers deliver fractions of the primary voltage and current to the meter. With properly set ratios
and multipliers, the readings of the meter can be used to determine the energy, voltage, current, or power of the
system.
From the Tree Menu, click General Settings>CT, PT, Ratios and System Hookup.
The screen fields and acceptable entries are as follows:
CT Ratios

Configuring Energy, Power Scaling, and Averaging
Use this setting to configure:
• The display of Power in the meter
• The display and storage of Energy in the meter
• The interval over which Average values are computed.
v Functional Overview of Energy Settings and Averaging:
n
Energy Scaling
Energy Setting includes:
• Digits (the number of digits in the reading)
• Decimals (the number of decimal places in the reading)
• Energy Scale: the scale of the reading – unit; kilo (number times 1000); Mega (number times 1 million).
Energy settings allow you to balance the resolution (or accuracy) of the energy stored, with the interval over which
energy rollover occurs. For example, the maximum resolution for a k scale reading is: 99999.999k.
To calculate the speed at which the energy will rollover, you must know the Energy Full Scale, which is computed
from the CT and PT Full Scale values (see Section 9.2.4.1). The formula for calculating Energy Full Scale is:
Wye system: CT Full Scale x PT Full Scale x 3
Delta system: CT Full Scale x PT Full Scale x 3 x √3
For example, for a CT Full Scale of 2000, PT Full Scale of 14400, Wye system:
2000 x 14400 x 3=86400000
In this example, the energy will increment at 86400000 Watts per hour, or 24000 Watts per second.
This value allows you to determine the number of digits, decimal places, and energy scale you want to configure for
the Energy settings, when you take into account the rollover time. To determine the number of hours before rollover,
use this formula:
[Max Resolution]/[Full Scale] = #Hours, where Max Resolution = maximum digits and decimals for the Energy scale
in use.
Using the example from above, with an energy scale of Mega, the formula would be:
99999.999 M/86.4 M = 1157.4074 hours or about 48 days until rollover.
NOTE: To increase the number of days until rollover, you can:
• Increase the number of digits (to 8)
• Decrease the number of decimal places (to 0)
• Increase the Energy Scale (to M).
n Demand
Averaging
Demand is the average rate of energy use over time. The IQ 250/260 supports two types of demand averaging:
Fixed demand and Sliding demand:
• Fixed demand records the average demand for time intervals that you define (usually 5, 15 or 30 minutes).
• Sliding demand functions like multiple, overlapping Fixed demand. You define the subintervals at which an
average of demand is calculated. An example of Sliding demand would be a 15-minute Demand block using
5-minute subintervals, thus providing a new demand reading every 5 minutes, based on the last 15 minutes.

NOTES:
• Only one Option Card input or output can be set to trigger an EOI pulse.
• The maximum rate for EOI Pulse used to trigger a log is once per minute.
• When you choose EOI Pulse, the meter takes a snapshot on the End of Interval Pulse condition, rather than on
a time interval. Below are two examples of using EOI Pulse for log recording.
Examples of EOI Pulse Recording:
• A Relay Option Card is installed in your meter and set to trigger on a state change. You can use EOI pulse to
take a snapshot upon that state change.
• An IQ 260 meter is connected on each side of a load. You want to take a snapshot of both sides of the load at
the same time. You can do this by connecting a Relay card in each of the meters to a device that will trigger
them. Then set the EOI pulse to take a snapshot when the devices are triggered.

Chapter 8:
Programming the IQ 250/260
Configuring a Relay Output/Digital Input Card (IQ250/260-IO1):
The Relay Output/Digital Input Option Card has:
· Two relay contact outputs for load switching
· Two wet/dry contact sensing digital inputs.
Accumulators in the software count the transitions of the Inputs and Outputs.
For technical specifications and hardware installation, refer to Chapter 7 of this manual.
NOTE: When installing a Relay Output/Digital Input card, we recommend you reset the accumulators for the card,
in order to prevent erroneous counts. See instructions on using the Reset Device Information screen to reset card
accumulators, later in this chapter.
An example use of the optional Relay Card is in monitoring the status of circuit breakers or relays in your electrical
system. The two status inputs could be used to monitor two circuit breakers, and the two relay outputs could be used
to sound an alarm upon the occurrence of a programmed out of limit condition (IQ 260, only). Relay outputs on IQ
250/260 can be manually triggered: see the “Performing Manual Relay Control” section, later in this chapter.
Click Relay Assignments to set the limits/alarm conditions (IQ 260, only) and labeling and compression options for the card’s Relay Outputs. From the Relay Assignments screen, you can:
• Configure up to 8 limits for each of the two Relay
Outputs (IQ 260)
• Set a Delay and Reset Delay for the Outputs (IQ 260)
• Assign each Output an Output Label, Open Label,
and Closed Label
• Assign an Accumulation Compression Factor for
each output
IMPORTANT! First use the Limits screen to set up the
limits you want to assign to an Output. See
instructions earlier in this chapter.
NOTE: The Limits functionality is only available for
the IQ 260. If you are connected to an IQ 250, you
will only see the Label and Accumulation
Compression Factor fields in this screen.
1. The available Limits appear in the Limit ID column.
To assign a Limit to an Output Relay:
Select the Alarm trigger from the pull-down menu next to the Limit ID. The options are:
• Above Limit (the Output is triggered when the Above Limit condition occurs)
• Below Limit (the Output is triggered when the Below Limit condition occurs).
You can assign the limit to one or both (or neither) of the Relay Outputs.
NOTE: A Relay operates when any one assigned Limit is tripped, and stays in the Set condition as long as one
Limit is in the Alarm state.
2. You can enter Set Delay and/or Reset Delay. These values are the delay before the Output is changed: Set is
when the common is shorted to Normal Open (this is the Set Condition).
3. The current Output Labels are displayed in the screen. These labels are used for Logging. To change the
Output labels, click in the Labels field you want to change, and enter a new label. The fields that can be changed
are:
• Output Label – Label ID
• Open Label – Open state ID
• Closed Label – Closed state ID

Chapter 8:
Programming the IQ 250/260
IQ 250/260 Meter
4. You can specify an Accumulation Compression Factor. The Compression Factor is used to adjust how high an
accumulator will go before rolling over. Because of this, it is useful in delaying rollover.
For example, if you select a Compression Factor of 10, each time 10 Pulse/State changes occur, the accumulator
count will increment by 1. The available Compression Factors are: 1, 10, 100, 1000, 10000, and 100000. The
default Compression Factor is 1.
5. To configure the Relay Inputs, click Digital Input Settings. Use this screen to set up Accumulators and Input
Labels.
• You can set up to two Input IDs for your Relay
Card, and assign a Label, Open Label, and
Closed Label for each.
• You can assign labels and other information for
Accumulators for the Inputs.
a. Make a selection in the Assigned to field.
The available selections are:
• Status Only
• EOI Pulse, Trigger on Contact Closing
• EOI Pulse, Trigger on Contact Opening
• EOI Pulse, Trigger on Contact Change
• Accumulator, Increment on Contact
Closing
• Accumulator, Increment on Contact Opening
• Accumulator, Increment on Contact Change
NOTES on End of Interval (EOI):
• EOI is triggered when the selected condition is met.
• EOI is used as a trigger for demand averaging: when the selected condition is met, the EOI delineates
an interval that results in demand averaging being performed.
• The minimum interval between EOI Pulses used to trigger demand averaging should be 5 minutes.
• Only one Option Card input or output can be set to trigger an EOI pulse.
b. Enter Units/Count. The Units/Count is the output ratio from the device that is being input into the meter.
For example, if you have a KYZ module that is outputting a pulse every 1.8 kWh, with the input set to
Accumulator, Increment on Contact Opening, you would set the Units/Count to be the value of the KYZ; in
this case either 1.8 or a ratio of that number.

NOTE: When installing a Pulse Output/Digital Input card, we recommend you reset the accumulators for the
card, in order to prevent erroneous counts. See instructions on using the Reset Device Information screen to reset
card accumulators, later in this chapter.
An example use of the Pulse Output/Digital Input Card is in a sub-metering application where a pulse output is
needed. The Input Accumulators allow you to count the pulses from another device, for example, a KYZ module or
another meter. The Output Accumulators allow you to count the pulses being output by the card.
The Pulse Output and Digital Input Card has two screens for configuration: the Pulse Output Settings screen

11000100 11100001 00011101 10111001 (binary)
The sign of the mantissa (and therefore the number) is 1, which represents a negative
value.
The Exponent is 10001001 (binary) or 137 decimal.
The Exponent is a value in excess 127. So, the Exponent value is 10.
The Mantissa is 11000010001110110111001 binary.
With the implied leading 1, the Mantissa is (1).C23B72 (hex).
The Floating Point Representation is therefore -1.75871956 times 2 to the 10.
Decimal equivalent: -1800.929
NOTES:
• Exponent = the whole number before the decimal point.
• Mantissa = the positive fraction after the decimal point.

IQ 250/260 Modbus Map
Important Note Concerning the IQ 250/260 Meter’s Modbus Map
In depicting Modbus Registers (Addresses), the IQ 250/260 meter’s Modbus map uses Holding Registers
only.
Hex Representation
The representation shown in the table below is used by developers of Modbus drivers and libraries, SEL
2020/2030 programmers and Firmware Developers. The IQ 250/260 meter’s Modbus map also uses this
representation.
Hex
0008 – 000F
Description
Meter Serial Number
Decimal Representation
The IQ 250/260 meter’s Modbus map defines Holding Registers as (4X) registers. Many popular SCADA
and HMI packages and their Modbus drivers have user interfaces that require users to enter these
Registers starting at 40001. So instead of entering two separate values, one for register type and one for
the actual register, they have been combined into one number.
The IQ 250/260 meter’s Modbus map uses a shorthand version to depict the decimal fields -i.e., not all of
the digits required for entry into the SCADA package UI are shown.
For Example:
You need to display the meter’s serial number in your SCADA application. The IQ 250/260 meter’s
Modbus map shows the following information for meter serial number:
Decimal
9 – 16
Description
Meter Serial Number
In order to retrieve the meter’s serial number, enter 40009 into the SCADA UI as the starting register, and
8 as the number of registers.


In order to work with SCADA and Driver packages that use the 40001 to 49999 method for
requesting holding registers, take 40000 and add the value of the register (Address) in the
decimal column of the Modbus Map. Then enter the number (e.g., 4009) into the UI as the
starting register.
For SCADA and Driver packages that use the 400001 to 465536 method for requesting
holding registers take 400000 and add the value of the register (Address) in the decimal
column of the Modbus Map. Then enter the number (e.g., 400009) into the UI as the starting
register. The drivers for these packages strip off the leading four and subtract 1 from the
remaining value. This final value is used as the starting register or register to be included
when building the actual modbus message.

Retrieving Logs Using the IQ 250/260 Meter with Option L’s Modbus Map
This section describes the log interface system of the IQ 250/260 meters with the logging option from a
programming point of view. It is intended for Programmers implementing independent drivers for Log
Retrieval from the meter. It describes the meaning of the meter’s Modbus Registers related to Log
Retrieval and Conversion, and details the procedure for retrieving a log’s records.
NOTES:


All references assume the use of Modbus function codes 0x03, 0x06, and 0x10, where each
register is a 2 byte MSB (Most Significant Byte) word, except where otherwise noted.
The caret symbol (^) notation is used to indicate mathematical “power.” For example, 2^8
means 28; which is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2, which equals 256.

Block Definitions
This section describes the Modbus Registers involved in retrieving and interpreting an IQ 250/260 meter’s
log. Other sections refer to certain ‘values’ contained in this section. See the corresponding value in this
section for details.
NOTES:


Register is the Modbus Register Address in 0-based Hexadecimal notation. To convert it to 1based decimal notation, convert from hex16 to decimal10 and add 1.
For example: 0x03E7 = 1000.
Size is the number of Modbus Registers (2 byte) in a block of data.
1) Historical Log Programmable Settings:
The Historical log is programmed using a list of Modbus Registers that will be copied into the
Historical Log record. In other words, the Historical Log uses a direct copy of the Modbus
Registers to control what is recorded at the time of record capture.
To supplement this, the programmable settings for the Historical Logs contain a list of descriptors,
which group registers into items. Each item descriptor lists the data type of the item, and the
number of bytes for that item. By combining these two lists, the Historical Log record can be
interpreted.
For example: Registers 0x03E7 and 0x03E8 are programmed to be recorded by the Historical
log. The matching descriptor gives the data type as float, and the size as 4 bytes. These
registers program the log to record “Primary Readings Volts A-N.”
Historical Log Blocks:
Start Register:
0x7917 (Historical Log 1)
Block Size:
192 registers per log (384 bytes)
The Historical log programmable settings are comprised of 3 blocks. Each Historical log block
is composed of 3 sections: The header, the list of registers to log, and the list of item
descriptors.
i.


# Registers: The number of registers to log in the record. The size of the record
in memory is [12 + (# Registers x 2)]. The size during normal log retrieval is [6 +
(# Registers x 2)]. If this value is 0, the log is disabled. Valid values are {0-117}.

# Sectors: The number of Flash Sectors allocated to this log. Each sector is
64kb, minus a sector header of 20 bytes. If this value is 0, the log is disabled.
Valid values are {0-15}.

Interval: The interval at which the Historical log’s Records are captured. This
value is an enumeration:

End of Interval (EOI) Pulse: Setting the interval to EOI causes a record to be logged whenever an
EOI pulse event is generated. This is most commonly used in conjunction with the Digital I/O Option
Cards.

NOTE: The interval between records will not be even (fixed), and thus should not be used with
programs that expect a fixed interval.
ii.
Register List:
Registers:
Size:
0x7919 – 0x798D
1 register per list item, 117 list items
The Register List controls what Modbus Registers are recorded in each record of the
Historical log. Since many items, such as Voltage, Energy, etc., take up more than 1
register, multiple registers need to be listed to record those items.
For example: Registers 0x03E7 and 0x03E8 are programmed to be recorded by the
historical log. These registers program the log to record “Primary Readings Volts A-N.”

Each unused register item should be set to 0x0000 or 0xFFFF to indicate that it
should be ignored.
The actual size of the record, and the number of items in the register list which are
used, is determined by the # registers in the header.
Each register item is the Modbus Address in the range of 0x0000 to 0xFFFF.


iii. Item Descriptor List:
Registers:
Size:
0x798E – 0x79C8
1 byte per item, 117 bytes (59 registers)
While the Register List describes what to log, the Item Descriptor List describes how to
interpret that information. Each descriptor describes a group of register items, and what
they mean.
Each descriptor is composed of 2 parts:

Type: The data type of this descriptor, such as signed integer, IEEE floating
point, etc. This is the high nibble of the descriptor byte, with a value in the range
of 0-14. If this value is 0xFF, the descriptor should be ignored.
ASCII: An ASCII string, or byte array


Size: The size in bytes of the item described. This number is used to determine
the pairing of descriptors with register items.
For example: If the first descriptor is 4 bytes, and the second descriptor is 2
bytes, then the first 2 register items belong to the 1st descriptor, and the 3rd
register item belongs to the 2nd descriptor.
NOTE: As can be seen from the example, above, there is not a 1-to-1 relation
between the register list and the descriptor list. A single descriptor may refer to
multiple register items.

NOTES:
 When Log Retrieval is engaged, the Log Availability value will be set to
the port that engaged the log. The Log Availability value will stay the
same until either the log has been disengaged, or 5 minutes have
passed with no activity. It will then reset to 0 (available).
 Each log can only be retrieved by one port at a time.
 Only one log at a time can be retrieved.

First Timestamp: Timestamp of the oldest record.

Last Timestamp: Timestamp of the newest record.
3) Log Retrieval Block:
The Log Retrieval Block is the main interface for retrieving logs. It is comprised of 2 parts: the
header and the window. The header is used to program the particular data the meter presents
when a log window is requested. The window is a sliding block of data that can be used to
access any record in the specified log.
 Session Com Port: The IQ 250/260 meter’s Com Port which is currently retrieving
logs. Only one Com Port can retrieve logs at any one time.

useful to determine a range of available data for non-interval based logs,
such as System Events.


checksum, 4-byte sequence number, 6-byte timestamp, and then N data
bytes for the record data.
Records Per Window: The number of records that fit evenly into a window.
This value is settable, as less than a full window may be used. This number tells
the retrieving program how many records to expect to find in the window.
(RecPerWindow x RecSize) = #bytes used in the window.
This value should be ((123 x 2) \ recSize), rounded down.

the log. It also provides the interface used to retrieve that data.
Registers:

Size:
125 registers

Window Status: The status of the current window. Since the time to prepare a
window may exceed an acceptable modbus delay (1 second), this acts as a state
flag, signifying when the window is ready for retrieval. When this value indicates
that the window is not ready, the data in the window should be ignored. Window
Status is Read-only, any writes are ignored.
0
Window is Ready
0xFF
Window is Not Ready

Record Number: The record number of the first record in the data window.
Setting this value controls which records will be available in the data window.


When the log is engaged, the first (oldest) record is “latched.” This means
that record number 0 will always point to the oldest record at the time of
latching, until the log is disengaged (unlocked).
To retrieve the entire log using auto-increment, set this value to 0, and
retrieve the window repeatedly, until all records have been retrieved.
NOTES:
 When auto-increment is enabled, this value will automatically increment so
that the window will “page” through the records, increasing by
RecordsPerWindow each time that the last register in the window is read.
 When auto-increment is not enabled, this value must be written-to
manually, for each window to be retrieved.

Auto-Increment


In the traditional Modbus retrieval system, you write the index of the block of data to retrieve, then
read that data from a buffer (window). To improve the speed of retrieval, the index can be
automatically incremented each time the buffer is read.
In the IQ 250/260, when the last register in the data window is read, the record index is
incremented by the Records per Window.

Function Code 0x23 is a user defined Modbus function code, which has a format similar to
Function Code 0x03, except for the inclusion of a “repeat count.” The repeat count (RC) is
used to indicate that the same N registers should be read RC number of times. (See the
Number of Repeats bullet on the previous page.)
NOTES:


By itself this feature would not provide any advantage, as the same data will be
returned RC times. However, when used with auto-incrementing, this function
condenses up to 8 requests into 1 request, which decreases communication
time, as fewer transactions are being made.
In the IQ 250/260 meter repeat counts are limited to 8 times for Modbus RTU,
and 4 times for Modbus ASCII.
The response for Function Code 0x23 is the same as for Function Code 0x03, with the data
blocks in sequence.
IMPORTANT: Before using function code 0x23, always check to see if the current connection
supports it. Some relay devices do not support user defined function codes; if that is the
case, the message will stall. Other devices don’t support 8 repeat counts.

Log Retrieval Procedure
The following procedure documents how to retrieve a single log from the oldest record to the newest
record, using the “normal” record type (see Scope). All logs are retrieved using the same method.
See following section for a Log Retrieval example.
NOTES:




This example uses auto-increment.
In this example, Function Code 0x23 is not used
You will find referenced topics in the Block Definitions section.
Modbus Register numbers are listed in brackets.
1. Engage the Log:
a) Read the Log Status Block.
i. Read the contents of the specific logs’ status block [0xC737+, 16 reg] (see Log
Headers).
ii. Store the # of Records Used, the Record Size, and the Log Availability.
iii. If the Log Availability is not 0, stop Log Retrieval; this log is not available at this time.
If Log Availability is 0, proceed to step 1b (Engage the log).
This step is done to ensure that the log is available for retrieval, as well as
retrieving information for later use.
b) Engage the log.
Write log to engage to Log Number, 1 to Enable, and the desired mode to Scope (default
0 (Normal)) [0xC34F, 1 reg]. This is best done as a single-register write.
This step will latch the first (oldest) record to index 0, and lock the log so that only
this port can retrieve the log, until it is disengaged.
c) Verify the log is engaged.
Read the contents of the specific logs’ status block [0xC737+, 16 reg] again to see if the
log is engaged for the current port (see Log Availability).
If the Log is not engaged for the current port, repeat step 1b (Engage the log).
d) Write the retrieval information.
i. Compute the number of records per window, as follows:
RecordsPerWindow = (246 \ RecordSize)
 If using 0x23, set the repeat count to 2-8. Otherwise, set it to 1.
 Since we are starting from the beginning for retrieval, the first record
index is 0.
ii. Write the Records per window, the Number of repeats (1), and Record Index (0)
[0xC350, 3 reg].
This step tells the meter what data to return in the window.
2. Retrieve the records:
a) Read the record index and window.
Read the record index, and the data window [0xC351, 125 reg].
 If the meter Returns a Slave Busy Exception, repeat the request.
 If the Window Status is 0xFF, repeat the request.
 If the Window Status is 0, go to step 2b (Verify record index).
NOTES:
 We read the index and window in 1 request to minimize communication time, and
to ensure that the record index matches the data in the data window returned.

Appendix B:
IQ 250/260 Modbus Map
Space in the window after the last specified record (RecordSize x
RecordPerWindow) is padded with 0xFF, and can be safely discarded.
b) Verify that the record index incremented by Records Per Window.
The record index of the retrieved window is the index of the first record in the window.
This value will increase by Records Per Window each time the window is read, so it
should be 0, N, N x 2, N x 3 . . . for each window retrieved.
 If the record index matches the expected record index, go to step 2c (Compute
next expected record index).
 If the record index does not match the expected record index, then go to step 1d
(Write the retrieval information), where the record index will be the same as the
expected record index. This will tell the meter to repeat the records you were
expecting.
c) Compute next Expected Record Index.
 If there are no remaining records after the current record window, go to step 3
(Disengage the log).
 Compute the next expected record index by adding Records Per Window, to the
current expected record index.
If this value is greater than the number of records, resize the window so it only
contains the remaining records and go to step 1d (Write the retrieval information),
where the Records Per Window will be the same as the remaining records.
3. Disengage the log:
Write the Log Number (of log being disengaged) to the Log Index and 0 to the Enable bit
[0xC34F, 1 reg].
Log Retrieval Example
The following example illustrates a log retrieval session. The example makes the following assumptions:











Log Retrieved is Historical Log (Log Index 2).
Auto-Incrementing is used.
Function Code 0x23 is not used (Repeat Count of 1).
The Log contains Volts-AN, Volts-BN, Volts-CN (12 bytes).
100 Records are available (0-99).
COM Port 2 (RS-485) is being used (see Log Availability).
There are no Errors.
Retrieval is starting at Record Index 0 (oldest record).
Protocol used is Modbus RTU. The checksum is left off for simplicity.
The IQ 250/260 meter is at device address 1.
No new records are recorded to the log during the log retrieval process.

rounded to 13 records per window. This allows the minimum number of requests to

NOTES:
 This retrieves the actual window. Repeat this command as many times as necessary
to retrieve all of the records when auto-increment is enabled.
 Note the filler record. When a log is reset (cleared) in the meter, the meter
always adds a first “filler” record, so that there is always at least 1 record in the log.
This “filler” record can be identified by the data being all 0xFF, and it being index 0.

IQ 250/260 Meter
If a record has all 0xFF for data, the timestamp is valid, and the index is NOT 0, then
the record is legitimate.
 When the “filler” record is logged, its timestamp may not be “on the interval.” The next
record taken will be on the next “proper interval,” adjusted to the hour.
For example, if the interval is 1 minute, the first “real” record will be taken on the next
minute (no seconds). If the interval is 15 minutes, the next record will be taken at :15,
:30, :45, or :00 - whichever of those values is next in sequence.
6) Compare the index with Current Index.
NOTES:
 The Current Index is 0 at this point, and the record index retrieved in step 5 is 0: thus
we go to step 8.
 If the Current Index and the record index do not match, go to step 7. The data that
was received in the window may be invalid, and should be discarded.
7) Write the Current Index to [0xC351, 2 reg].

NOTES:
 This step manually sets the record index, and is primarily used when an out-of-order
record index is returned on a read (step 6).
 The example assumes that the second window retrieval failed somehow, and we need
to recover by requesting the records starting at index 13 again.
8) For each record in the retrieved window, copy and save the data for later
interpretation.
9) Increment Current Index by RecordsPerWindow.
NOTES:
 This is the step that determines how much more of the log we need to retrieve.
 On the first N passes, Records Per Window should be 13 (as computed in step 4),
and the current index should be a multiple of that (0, 13, 26, . . .). This amount will
decrease when we reach the end (see step 10).
 If the current index is greater than or equal to the number of records (in this case 100),
then all records have been retrieved; go to step 12. Otherwise, go to step 10 to check
if we are nearing the end of the records.
10) If number records – current index < RecordsPerWindow, decrease to match.
NOTES:
 Here we bounds-check the current index, so we don’t exceed the records available.
 If the number of remaining records (#records – current index) is less than the Records
per Window, then the next window is the last, and contains less than a full window of
records. Make records per window equal to remaining records (#records-current

IQ 250/260 Meter
Flash error counters are reset to zero in the unlikely event that both copies in EEPROM
are corrupted.
A “babbling log” is one that is saving records faster than the meter can handle long term.
Onset of babbling occurs when a log fills a flash sector in less than an hour. For as long
as babbling persists, a summary of records discarded is logged every 60 minutes.
Normal logging resumes when there have been no new append attempts for 30 seconds.
Logging of diagnostic records may be suppressed via a bit in programmable settings.
2. Historical Log Record:

values . . .
N
Size: 6+2 x N bytes (12+2 x N bytes), where N is the number of registers stored.
Data: The Historical Log Record data is 2 x N bytes, which contains snapshots of the values of
the associated registers at the time the record was taken. Since the meter uses specific
registers to log, with no knowledge of the data it contains, the Programmable Settings need
to be used to interpret the data in the record. See Historical Log Programmable Settings
for details.

In each group of 40 registers, the first register represents
the fundamental frequency or first harmonic, the second
represents the second harmonic, and so on up to the
40th register which represents the 40th harmonic.
40
Harmonic magnitudes are given as % of the fundamental
magnitude. Thus the first register in each group of 40
will typically be 9999. A reading of 10000 indicates
invalid.

Relay Accumulators Scaling
UINT16

-------- 22221111
The nibble informs what should be the scaling of the
accumulator 0=no-scaling, 1=0.1, 2=0.01, 3= 1m,
4=0.1m, 5=0.01m, 6=1u, 7=0.1u; the value 15 disable
the accumulator.
Example: suppose that the internal input accumulator #1
is 12345, and its corresponding scaling setting is “0011”
(3 decimal). Then, the accumulator will be read as:
Scaling 3, means 1m or 0.001.
Scaled accumulator = 12345 * 0.001 = 12 (Twelve).

Value read from the source register at which High
nominal current will be output. Example: for the 4-20mA
card, if this register is programmed with 750, then the

Value read from the source register at which Low
nominal current will be output. Example: for the 4-20mA
card, if this register is programmed with 0, then the
current output will be 4mA when the value read from the
source register is 0.

accumulator 0=no-scaling, 1=0.1, 2=0.01, 3= 1m,
4=0.1m, 5=0.01m, 6=1u, 7=0.1u; the value 15 disable
the accumulator.
Example: suppose that the internal input accumulator #1
is 12345, and its corresponding scaling setting is “0011”
(3 decimal). Then, the accumulator will be read as:
Scaling 3, means 1m or 0.001.
Scaled accumulator = 12345 * 0.001 = 12 (Twelve).

When value 'nnn' is non-zero, it determines which of the

The polarity bit 'P' tells the event to be detected: 1=opento-close; 0=close-to-open. There is no “any-change”
detection mode.

Data Formats
ASCII
ASCII characters packed 2 per register in high, low order and without any termination characters.
SINT16 / UINT16
16-bit signed / unsigned integer.
SINT32 / UINT32
32-bit signed / unsigned integer spanning 2 registers. The lower-addressed register is the high order half.
FLOAT
32-bit IEEE floating point number spanning 2 registers. The lower-addressed register is the high order half (i.e., contains the exponent).
TSTAMP
3 adjacent registers, 2 bytes each. First (lowest-addressed) register high byte is year (0-99), low byte is month (1-12). Middle register high byte is day(1-31), low byte is hour (0-23 plus DST bit).
DST (daylight saving time) bit is bit 6 (0x40). Third register high byte is minutes (0-59), low byte is seconds (0-59). For example, 9:35:07AM on October 12, 2049 would be 0x310A, 0x0C49,
0x2307, assuming DST is in effect.
Notes
1
All registers not explicitly listed in the table read as 0. Writes to these registers will be accepted but won't actually change the register (since it doesn't exist).
2
Meter Data Section items read as 0 until first readings are available or if the meter is not in operating mode. Writes to these registers will be accepted but won't actually change the register.
3
Register valid only in programmable settings update mode. In other modes these registers read as 0 and return an illegal data address exception if a write is attempted.
4
Meter command registers always read as 0. They may be written only when the meter is in a suitable mode. The registers return an illegal data address exception if a write is attempted in an incorrect mode.
5
If the password is incorrect, a valid response is returned but the command is not executed. Use 5555 for the password if passwords are disabled in the programmable settings.
6
M denotes a 1,000,000 multiplier.
7
Each identifier is a Modbus register. For entities that occupy multiple registers (FLOAT, SINT32, etc.) all registers making up the entity must be listed, in ascending order. For example, to log phase A volts, VAs,
voltage THD, and VA hours, the register list would be 0x3E7, 0x3E8, 0x411, 0x412, 0x176F, 0x61D, 0x61E and the number of registers (0x7917 high byte) would be 7.
8
Writing this register causes data to be saved permanently in nonvolatile memory. Reply to the command indicates that it was accepted but not whether or not the save was successful. This can only be determined
after the meter has restarted.
Reset commands make no sense if the meter state is LIMP. An illegal function exception will be returned.
9
10
Energy registers should be reset after a format change.
11
Entities to be monitored against limits are identified by Modbus address. Entities occupying multiple Modbus registers, such as floating point values, are identified by the lower register address. If any of the 8 limits is
unused, set its identifier to zero. If the indicated Modbus register is not used or is a nonsensical entity for limits, it will behave as an unused limit.
12
There are 2 setpoints per limit, one above and one below the expected range of values. LM1 is the "too high" limit, LM2 is "too low". The entity goes "out of limit" on LM1 when its value is greater than the setpoint. It
remains "out of limit" until the value drops below the in threshold. LM2 works similarly, in the opposite direction. If limits in only one direction are of interest, set the in threshold on the "wrong" side of the setpoint.
Limits are specified as % of full scale, where full scale is automatically set appropriately for the entity being monitored:
current FS = CT numerator * CT multiplier
voltage FS = PT numerator * PT multiplier
3 phase power FS = CT numerator * CT multiplier * PT numerator * PT multiplier * 3 [ * SQRT(3) for delta hookup]
single phase power FS = CT numerator * CT multiplier * PT numerator * PT multiplier [ * SQRT(3) for delta hookup]
frequency FS = 60 (or 50)
power factor FS = 1.0
percentage FS = 100.0
angle FS = 180.0
13
THD not available shows 10000 in all THD and harmonic magnitude and phase registers for the channel. THD may be unavailable due to low V or I amplitude, delta hookup (V only), or meter model.
14
Option Card Identification and Configuration Block is an image of the EEPROM on the card.
15
A block of data and control registers is allocated for each option slot. Interpretation of the register data depends on what card is in the slot.
16
Measurement states: Off occurs during programmable settings updates; Run is the normal measuring state; Limp indicates that an essentail non-volatile memory block is corrupted; and Warmup occurs briefly
(approximately 4 seconds) at startup while the readings stabilize. Run state is required for measurement, historical logging, demand interval processing, limit alarm evaluation, min/max comparisons, and THD
calculations. Resetting min/max or energy is allowed only in run and off states; warmup will return a busy exception. In limp state, the meter reboots at 5 minute intervals in an effort to clear the problem.
17
Limits evaluation for all entites except demand averages commences immediately after the warmup period. Evaluation for demand averages, maximum demands, and minimum demands commences at the end of the
first demand interval after startup.

Depending on the meter model, there are 15, 29, or 45 flash sectors available in a common pool for distribution among the historical and waveform logs. The pool size, number of sectors for each log, and the number
of registers per record together determine the maximum number of records a log can hold.
S = number of sectors assigned to the log,
H = number of Modbus registers to be monitored in each historical record (up to 117),
R = number of bytes per record = (12 + 2H) for historical logs
N = number of records per sector = 65516 / R, rounded down to an integer value (no partial records in a sector)
T = total number of records the log can hold = S * N
.
20
Only 1 input on all digital input cards may be specified as the end-of-interval pulse.

Appendix C:
IQ 250/260 Meter Using DNP Mapping for IQ 250/260
App.C
Using DNP Mapping for IQ 250/260
Overview
This Appendix describes the functionality of the IQ 250/260 meter's version of the DNP protocol. A DNP
programmer needs this information to retrieve data from the meter. The DNP version used by the IQ
250/260 is a reduced set of the Distributed Network Protocol Version 3.0 subset 2; it gives enough
functionality to get critical measurements from the meter.
This DNP version supports Class 0 object/qualifiers 0,1,2,6, only. No event generation is supported. The
IQ 250/260 meter always acts as a secondary device (slave) in DNP communication.
Physical Layer
The IQ 250/260 meter’s DNP version uses serial communication. It can be assigned to Port 2 (RS485
compliant port) or any communication capable option board. Speed and data format is transparent: they
can be set to any supported value.
Data Link Layer
The IQ 250/260 can be assigned with a value from 1 to 65534 as the target device address for. The data
link layer follows the standard frame FT3 used by the DNP Version 3.0 protocol, but only 4 functions are
implemented: Reset Link, Reset User, Unconfirmed User Data, and Link Status, as depicted in following
table.

Table C.1: Supported Link Functions
.[dst] and [src] are the device address of the IQ 250/260 and Master device, respectively.
In order to establish optimal communication with the meter, we recommend that you perform the Reset
Link and Reset User functions. The Link Status is not mandatory, but can be performed as well. The intercharacter time-out for DNP is 1 second. If this amount of time, or more, elapses between two consecutive
characters within a FT3 frame, the frame will be dropped.
The inter-character time-out for DNP Lite is 1 second. If this amount of time, or more, elapses between
two consecutive characters within a FT3 frame, the frame will be dropped.

Appendix C:
Using DNP Mapping for IQ 250/260
IQ 250/260 Meter
Application Layer
The IQ 250/260 meter’s DNP version supports the Read function, Write Function, the Direct Operate
function and the Direct Operate Unconfirmed function.
 The Read function (code 01) provides a means for reading the critical measurement data from
the IQ 250/260 meter. This function should be posted to read object 60 variation 1, which will
read all the available Class 0 objects from the DNP register map. See register map in following
section. In order to retrieve all objects with their respective variations, the qualifier must be set to
ALL (0x06). See the DNP Message Layouts for an example showing a read Class 0 request data
from the IQ 250/260.

The Write function (code 02) provides a mean for clearing the Device restart bit in the Internal
Indicator register only. This is mapped to Object 80, point 0 with variation 1. When clearing the
restart device indicator use qualifier 0. The DNP Message Layouts section shows the supported
frames for this function.

The Direct Operate function (code 05) is intended for resetting the energy counters and the
demand counters (minimum and maximum energy registers). These actions are mapped to
Object 12, point 0 and point 2, that are seen as a control relay.
The relay must be operated (On) in 0 msec and released (Off) in 1 msec only. Qualifiers 0x17 or
x28 are supported for writing the energy reset. Sample frames are shown in the DNP Message
Layouts section.

The Direct Operate Unconfirmed (or Unacknowledged) function (code 06) is intended for
asking the communication port to switch to Modbus RTU protocol from DNP Lite. This switching
is seen as a control relay mapped into Object 12, point 1 in the IQ 250/260. The relay must be
operated with qualifier 0x17, code 3 count 0, with 0 millisecond on and 1 millisecond off, only.
After sending this request the current communication port will accept Modbus RTU frames only.
To make this port go back to DNP protocol, the unit must be power-recycled. The DNP Message
Layouts section shows the constructed frame to perform DNP to Modbus RTU protocol change.
Error Reply
In the case of an unsupported function, or any other recognizable error, an error reply will be generated
from the IQ 250/260 to the Primary station (the requester). The Internal Indicator field will report the type
of error: unsupported function or bad parameter.
The broadcast acknowledge and restart bit, are also signaled in the internal indicator but they do not
indicate an error condition.

Internal Indication Bits
Bits implemented in the IQ 250/260 meter are listed below. All others are always reported as zeroes.
Bad Function
Occurs if the function code in a User Data request is not Read (0x01), Write (0x02), Direct Operate
(0x05), or Direct Operate, No Ack (0x06).
Object Unknown
Occurs if an unsupported object is specified for the Read function. Only objects 10, 20, 30, and 60 are
supported.
Out of Range
Occurs for most other errors in a request, such as requesting points that don’t exist or direct operate
requests in unsupported formats.
Buffer Overflow
Occurs if a read request or a read response is too large for its respective buffer. In general, if the request
overflows, there will be no data in the response while if the response overflows at least the first object will
be returned. The largest acceptable request has a length field of 26, i.e. link header plus 21 bytes more,
not counting checksums. The largest possible response has 7 blocks plus the link header.
Restart
All Stations
These 2 bits are reported in accordance with standard practice.
