Using the IQ 250/260 IQ 250/260 Meter
Performing Watt-Hour Accuracy Testing (Verication)
To be certied for revenue metering, power providers
and utility companies must verify that the billing energy
meter performs to the stated accuracy. To conrm the
meters performance and calibration, power providers use
eld 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.
• Refer to Figure 6.5 for an example of how this process works.
• Refer to Table 6.1 for the Wh/Pulse Constants for Accuracy Testing.

8 Programming the IQ 250/260
Overview
The IQ 250/260 Meter can be congured using either the meter Face Buttons (Menu, Enter, Down and Right) or
Eaton Meter Conguration Software. To connect to the meter for software conguration, use the RS485 port (Com
2) on the back panel of the meter.
The 250/260T must be congured with the Eaton Meter Conguration Software, using the RS485 port, since it does
not have a front panel.
This chapter contains instructions for programming the IQ 250/260 Meter and Transducer using the Eaton Meter
Conguration Software.
Connecting to the IQ 250/260
1. Open Eaton Meter Conguration Software.
2. Click the Connect icon on the Title bar or Connection>Quick Connect.
3. If you are connecting to the IQ 250/260 through your PC:
a. Make sure the Serial Port radio button is selected.
b. Enter Device Address (1-247).
c. Select Baud Rate from the pull-down menu.
d. Select the port you are using from the pull-down menu. The
Available Ports/All Ports radio buttons determine which port selections
the menu displays.
e. Select Modbus RTU from the Protocol pull-down menu.
f. Select Flow Control: None or Hardware.
g. Select Echo Mode: No Echo or Static Echo.
If you are connecting to the Meter through the Power Xpert® Gateway:
a. Make sure the Network radio button is selected.
b. Enter Device Address (1-247).
c. Enter the Gateway’s IP Address.
d. Enter Network Port.
e. Protocol defaults to Modbus TCP.
4. Click the Connect button. You will see the Device Status
screen, shown on the right.
NOTE for IQ 250/260 Transducer:
When the IQ 250/260T is powered up, for 10
seconds you can connect to the meter using the
Factory Initial Default Settings (even if the Device
Prole has been changed). After 10 seconds,
the Device Prole reverts to the actual Device Prole
in use.

Chapter 8:
Programming the IQ 250/260 IQ 250/260 Meter
Conguring Energy, Power Scaling, and Averaging
Use this setting to congure:
• 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 congure 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 dene (usually 5, 15 or 30 minutes).
Sliding demand functions like multiple, overlapping Fixed demand. You dene 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.
Chapter 8:

From the Tree Menu, click Energy Settings> Energy, Power Scaling, and Averaging.
The screen elds and acceptable entries are as follows:
Energy Settings
Energy Digits: 5; 6; 7; 8
Energy Decimal Places: 0 - 6
Energy Scale: unit; kilo (K); Mega (M)
For example: a reading for Digits: 8; Decimals: 3;
Scale: K would be formatted: 00123.456k
NOTES:
v Your selection in the Energy Settings elds
determines the precision of energy stored for
display and polling. Refer to the Functional
Overview at the beginning of this section for more
information.
v If you are changing the energy settings, we
recommend you rst reset the Energy Accumulators,
in order to prevent erroneous counts. See instructions
for resetting the meter’s Energy Accumulators, later in
this chapter.
Power Settings:
Power Scale: Auto; unit; kilo (K); Mega (M)
Apparent Power (VA) Calculation Method: Arithmetic Sum or Vector Sum
Demand Averaging:
Type: Fixed or Sliding
Interval (Fixed demand) or Sub-Interval (Sliding demand) in minutes: 5; 15; 30; 60
Number of Subintervals: 1; 2; 3; 4
Interval Window: This eld is display only. It is the product of the values entered in the Sub-Interval and Number
of Subintervals elds.
NOTE: You will only see the Number of Subintervals and Interval Window elds if you select Sliding Demand.
NOTE: If you have set an Input to trigger End of Interval (EOI) demand averaging (using either a Relay Output/
Digital Input or a Pulse Output/Digital Input Option card) any entry you make in the Demand Averaging eld will be

Conguring Limits (IQ 260 Only)
Use this screen to assign Limits for the meter.
v Functional Overview for Limits:
Limits are transition points used to divide acceptable and unacceptable measurements. When a value goes
above or below the limit, an out-of-limit condition occurs. You can set and congure up to eight Limits for the
IQ 260 meter.
Once they are congured, you can view the out-of-Limits (or Alarm) conditions in the Limits Polling screen.
You can assign the eight limits to readings from three groups of parameters:
Readings (Instantaneous Voltage; Instantaneous Current; Total and Per Phase Power and Power Factor;
Frequency; and Neutral Current)
Demand (Current; Per Phase, Total Power and Power Factor)
THD (For IQ 260, voltage and current)
From the Tree Menu, click Power Quality and Alarm Settings>Limits.
The current settings for Limits are shown in the
screen.
The bottom of the screen shows the Full Scale values
for:
• Voltage

To Congure a Limit:
Double-click on the Field to set the following values:
Above and Below Set Point: % of Full Scale (the point at which the reading goes out of limit)
Examples: 100% of 120V Full Scale = 120V
90% of 120V Full Scale = 108V
Above and Below Return Hysteresis: (the point at which the reading goes back within limit)
Examples: Above Set Point = 110% Below Set Point = 90%
(Out of Limit above 132V) (Out of Limit below 108V)
Above Return Hysteresis = 105% Below Return Hysteresis = 95%
(Stay Out of Limit until below 126V) (Stay Out of Limit until above 114V)
The Primary elds are display only. They show what the set point and return hysteresis value are for each limit.
NOTES:
• If you are entering negative limits, be aware that the negative value affects the way the above and below limits
function, since negative numbers are processed as signed values.
• If the Above Return Hysteresis is greater than the Above Set Point, the Above Limit is Disabled; if the Below
Return Hysteresis is less than the Below Set Point, the Below Limit is Disabled. You may want to use this feature
to disable either Above or Below Limit conditions for a reading.

Chapter 8:
IQ 250/260 Meter Programming the IQ 250/260
www.eaton.com IB02601006E 8-15
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.
NOTE: There are two display elds at the bottom of the Historical Log Prole screen. They show the Total Bytes
Used and the Bytes Remaining for this historical log. These elds are updated as you make selections on the

www.eaton.com IB02601006E 8-25
Conguring 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 specications 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 op-
tions for the card’s Relay Outputs. From the Relay Assignments screen, you can:
• Congure 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 elds 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 eld you want to change, and enter a new label. The elds that can be changed
are:
Output Label – Label ID
Open Label – Open state ID
Closed Label – Closed state ID
8-26 IB02601006E www.eaton.com
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 congure 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 eld.
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 conguration: the Pulse Output Settings screen
and the Digital Input Settings screen.
1. Click Pulse Output Settings.

The formula to interpret a Floating Point Value is: -1sign x 2 exponent-127x1.mantissa = 0x0C4E11DB9
-1sign x 2 137-127 x 1· 1000010001110110111001
-1 x 210 x 1.75871956
-1800.929
Formula Explanation:
C4E11DB9 (hex) 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.

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 Description
0008 – 000F 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 Description
9 – 16 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.
Data Formats
Timestamp: Stores a date from 2000 to 2099. Timestamp has a Minimum resolution of 1 second.
Byte 0 1 2 3 4 5
Value Year Month Day Hour Minute Second
Range 0-99 (+2000) 1-12 1-31 0-23 0-59 0-59
Mask 0x7F 0x0F 0x1F 0x1F 0x3F 0x3F
The high bits of each timestamp byte are used as flags to record meter state information at the time of the
timestamp. These bits should be masked out, unless needed.
IQ 250/260 Meter Logs
The IQ 250/260 meter has 2 logs: System Event and 1 Historical log. Each log is described below.
1) System Event ( 0 ) : The System Event log is used to store events which happen in, and to, the
meter. Events include Startup, Reset Commands, Log Retrievals, etc.
The System Event Log Record takes 20 bytes, 14 bytes of which are available when the log is
retrieved.
Byte 0 1 2 3 4 5 6 7 8 9 10 11 12 13
Value timestamp Group Event Mod Chan Param1 Param2 Param3 Param4
2) Historical Log ( 2 ) : The Historical Log records the values of its assigned registers at the
programmed interval.
NOTE: See Block Definitions (on the next page) for details on programming and interpreting the
log.

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 1-
based 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. Header:
Registers: 0x7917 – 0x7918
Size: 2 registers
Byte 0 1 2 3
Value # Registers # Sectors Interval
# 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:
Appendix B:
Modbus Mapping for IQ 250/260 IQ 250/260 Meter
B-6 IB02601006E www.eaton.com
0x01 1 minute
0x02 3 minute
0x04 5 minute
0x08 10 minute
0x10 15 minute
0x20 30 minute
0x40 60 minute
0
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: 0x7919 – 0x798D
Size: 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: 0x798E – 0x79C8
Size: 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
1 Bitmap: A collection of bit flags
2 Signed Integer: A 2’s
Complement integer
3 Float: An IEEE floating point
4 Energy: Special Signed Integer, where the value is
adjusted by the energy settings in the meter’s
Programmable Settings.
Appendix B:
IQ 250/260 Meter IQ 250/260 Modbus Map
www.eaton.com IB02601006E B-7
}
5 Unsigned Integer
6 Signed Integer 0.1 scale: Special Signed Integer, where
the value is divided by 10 to give a 0.1 scale.
7-14 Unused
15 Disabled: used as end list marker.
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.
Register Items Descriptors
0x03C7 Float, 4 byte
0x03C8
0x1234 Signed Int, 2 byte
NOTE: The sum of all descriptor sizes must equal the number of bytes in the
data portion of the Historical Log record.
2) Log Status Block:
The Log Status Block describes the current status of the log in question. There is one header block
for each of the logs. Each log’s header has the following base address:
Log Base Address
System: 0xC747
Historical 1: 0xC757
Bytes Value Type Range # Bytes
0 - 3 Max Records UINT32 0 to 4,294,967,294 4
4 - 7 Number of Records Used UINT32 1 to 4,294,967,294 4
8 - 9 Record Size in Bytes UINT16 4 to 250 2
10 - 11 Log Availability UINT16 2
12 - 17 Timestamp, First Record TSTAMP 1Jan2000 - 31Dec2099 6
18 - 23 Timestamp, Last Record TSTAMP 1Jan2000 - 31Dec2099 6
24 - 31 Reserved 8
Max Records: The maximum number of records the log can hold given the record
size, and sector allocation. The data type is an unsigned integer from 0 – 2^32.
# Records Used: The number of records stored in the log. This number will equal
the Max Records when the log has filled. This value will be set to 1 when the log is
reset. The data type is an unsigned integer from 1 – 2^32.
Appendix B:
Modbus Mapping for IQ 250/260 IQ 250/260 Meter
B-8 IB02601006E www.eaton.com
NOTE: The first record in every log before it has rolled over is a “dummy” record,
filled with all 0xFF’s. When the log is filled and rolls over, this record is overwritten.
Record Size: The number of bytes in this record, including the timestamp. The data
type is an unsigned integer in the range of 14 – 242.
Log Availability: A flag indicating if the log is available for retrieval, or if it is in use
by another port.
0 Log Available for retrieval
1 Not used
2 In use by COM2 (RS485)
3 In use by COM3 (Option Card 1)
4 In use by COM4 (Option Card 2)
0xFFFF Log Not Available - the log cannot be retrieved. This
indicates that the log is disabled.
NOTE: To query the port by which you are currently connected, use the
Port ID register:
Register: 0x1193
Size: 1 register
Description: A value from 1-4, which enumerates the port that the
requestor is currently connected on.
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.
Registers: 0xC34E – 0xC34E
Size: 1 register
0 No Session Active
1 Not used
2 COM2 (RS485)
3 COM3 (Communications Capable Option Card 1)

i. The Log Retrieval Header is used to program the log to be retrieved, the record(s) of
that log to be accessed, and other settings concerning the log retrieval.
Registers: 0xC34F 0xC350
Size: 2 registers
Log Number: The log to be retrieved. Write this value to set which log is being
retrieved.
0 System Events
1 Alarms
2 Historical Log
Enable: This value sets if a log retrieval session is engaged (locked for retrieval)
or disengaged (unlocked, read for another to engage). Write this value with
1(enable) to begin log retrieval. Write this value with 0(disable) to end log
retrieval.
0 Disable
1 Enable
Scope: Sets the amount of data to be retrieved for each record. The default
should be 0 (normal).
0 Normal
1 Timestamp Only
2 Image
Normal [0]: The default record. Contains a 6-byte timestamp at the
beginning, then N data bytes for the record data.
Timestamp [1]: The record only contains the 6-byte timestamp. This is most
useful to determine a range of available data for non-interval based logs,
such as System Events.
Image [2]: The full record, as it is stored in memory. Contains a 2-byte
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.

Number of Repeats: Specifies the number of repeats to use for the Modbus
Function Code 0x23 (35) (See next page for more information on this Function
Code). Since the meter must pre-build the response to each log window request,
this value must be set once, and each request must use the same repeat count.
Upon reading the last register in the specified window, the record index will
increment by the number of repeats, if auto-increment is enabled.
0 Disables auto-increment

ii. The Log Retrieval Window block is used to program the data you want to retrieve from
the log. It also provides the interface used to retrieve that data.
Registers: 0xC351 - 0xC3CD
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.
Log Retrieval Data Window: The actual data of the records, arranged
according to the above settings.
Appendix B:

Log Retrieval
Log Retrieval is accomplished in 3 basic steps:
1. Engage the log.
2. Retrieve each of the records.
3. Disengage the log.
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.
Modbus Function Code 0x23
QUERY
Field Name Example (Hex)
Slave Address 01
Function 23
Starting Address Hi C3
Starting Address Lo 51
# Points Hi 00
# Points Lo 7D
Repeat Count 04
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 Meter IQ 250/260 Modbus Map
www.eaton.com IB02601006E B-13
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.

www.eaton.com IB02601006E B-15
-Register Address: 0xC350
-# Registers: 3, 6 bytes
Data:
-Records per Window: 13. Since the window is 246 bytes, and the record is 18
bytes, 246\18 = 13.66, which means that 13 records
evenly fit into a single window. This is 234 bytes, which
means later on, we only need to read 234 bytes (117
registers) of the window to retrieve the records.
-# of Repeats: 1. We are using auto-increment (so not 0), but not
function code 0x23.
-Window Status: 0 (ignore)
-Record Index: 0, start at the first record.
------------------------------
Receive: 0110C3500003 (command ok)
NOTES:
This sets up the window for retrieval; now we can start retrieving the records.
As noted above, we compute the records per window as 246\18 = 13.66, which is
rounded to 13 records per window. This allows the minimum number of requests to
be made to the meter, which increases retrieval speed.
5) Read [0xC351, 125 reg], first 2 reg is status/index, last 123 reg is window data. Status
OK.
Send: 0103 C351 007D

06071710160042FAAACF42FAAD1842FAA9A8 . . .
Data:
-Window Status: 0x00 = the window is ready.
-Index: 0x00 = 0, The window starts with the 0’th record, which
is the oldest record.
-Record 0: The next 18 bytes is the 0’th record (filler).
-Timestamp: 0x060717101511, = July 23, 2006, 16:21:17
-Data: This record is the “filler” record. It is used by the meter
so that there is never 0 records. It should be ignored. It
can be identified by the data being all 0xFF.
NOTE: Once a log has rolled over, the 0’th record will be
a valid record, and the filler record will disappear.
-Record 1: The next 18 bytes is the 1’st record.
-Timestamp: 0x060717101600 July 23, 2006, 16:22:00
-Data:
-Volts AN: 0x42FAAACF, float = 125.33~
-Volts BN: 0x42FAAD18, float = 125.33~
-Volts CN: 0x42FAA9A8, float = 125.33~
. . . 13 records
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.
Appendix B:
Modbus Mapping for IQ 250/260 IQ 250/260 Meter
B-16 IB02601006E www.eaton.com
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].
Send: 0110 C351 0002 04 00 00000D
Command:
-Register Address: 0xC351
-# Registers: 2, 4 bytes
Data:
-Window Status: 0 (ignore)
-Record Index: 0x0D = 13, start at the 14th record.
------------------------------
Receive: 0110C3510002 (command ok)
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
Appendix B:

www.eaton.com IB02601006E B-17
index). In this example, this occurs when current index is 91 (the 8’th window). There
are now 9 records available (100-91), so make Records per Window equal 9.
11) Repeat step 5 through 10.
NOTES:
Go back to step 5, where a couple of values have changed.
Pass CurIndex FirstRecIndex RecPerWindow
0 0 0 13

6 78 78 13
7 91 91 9
8 100 -- ---- -- -----
At pass 8, since Current Index is equal to the number of records (100), log retrieval
should stop; go to step 12 (see step 9 Notes).
12) No more records available, clean up.
13) Write 0x0000 -> [0xC34F, 1 reg], disengage the log.
Send: 0106 C34F 0000
Command:
-Register Address: 0xC34F

------------------------------
Receive: 0106C34F0000 (echo)

This disengages the log, allowing it to be retrieved by other COM ports.
The log will automatically disengage if no log retrieval action is taken for 5 minutes.

occurred: 1 = acquire sector, 2 = startup, 3 = empty sector, 4 = release sector, 5 = write
data

o Flash error counters are reset to zero in the unlikely event that both copies in EEPROM
are corrupted.
o 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.
o Logging of diagnostic records may be suppressed via a bit in programmable settings.
2. Historical Log Record:
Byte 0 1 2 3 4 5 6 . . N
Value timestamp values . . .
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.

1.Use the settings from Programmable settings for scale
and decimal point location. (see User Settings Flags)
2. Per phase power and PF have values
only for WYE hookup and will be
zero for all other hookups.
3. If the reading is 10000 that means that the value is out
of range. Please adjust the programmable settings in
that case. The display will also show '----' in case of over
range.

THD Block (Note 13)
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.
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.
Convert individual samples to volts or amps:
V or A = (sample * scale factor) / 1,000,000
Samples update in conjunction with THD and harmonics;
samples not available (all zeroes) if THD not available.
