1 GENERAL
This document specifies a subset of the Modbus serial communications protocol used to transfer data between a
master computer station and the PM172EH. The document provides the complete information necessary to
develop third-party communications software capable of communication with the Series PM172EH Powermeters.
Additional information concerning communications operation, configuring the communications parameters, and
communications connections is found in "PM172EH Series Powermeter, Installation and Operation Manual".

IMPORTANT

1. In 3-wire connection schemes, the unbalanced current and phase readings for power factor, active
power, and reactive power will be zeros, because they have no meaning. Only the total three-phase
power values can be used.
2. In 4LN3, 4LL3, 3LN3 and 3LL3 wiring modes, harmonic voltages will be line-to-neutral voltages; in other
modes, they will be line-to-line voltages. In a 3-wire direct connection, harmonic voltages and waveforms
will represent line-to-neutral voltages as they appear on the instrument's input transformers. In 3OP2 and
3OP3 wiring modes, voltage harmonics and waveforms will be given only for phases L12 and L23.
3. Most of the advanced features are configured using multiple setup parameters that can be accessed in
some contiguous registers. When writing the setup registers, it is recommended to write all the registers
at once using a single request, or to clear (zero) the setup before writing into separate registers.

4
2 MODBUS FRAMING
2.1 Transmission Mode
The protocol uses the Modbus Remote Terminal Unit (RTU) transmission mode. In RTU mode, data is sent in 8-
bit binary characters. The 8 bit even parity or 8 bit no parity data format must be selected when configuring the
instrument communications. The data format is shown in the following table.

Table 2-1 RTU Data Format

Field No. of bits
Start bit 1
Data bits 1 8
Parity (optional) 1
Stop bit 1
1 Least significant bit first

2.2 The RTU Frame Format

Frame synchronization is maintained in RTU transmission mode by simulating a synchronization message. The
receiving device monitors the elapsed time between receptions of characters. If three and one-half character
times elapse without a new character or completion of the frame, then the device flushes the frame and assumes
that the next byte received will be an address. The frame format is defined below.

The maximum query and response message length is 256 bytes including check characters.
RTU Message Frame Format
T1 T2 T3 Address Function Data CRC Check T1 T2 T3
8 bits 8 bits N * 8 bits 16 bits

2.3 Address Field

The address field contains a user assigned address (1-247) of the instrument that is to receive a message.
Address 0 is used in broadcast mode to transmit to all instruments (broadcast mode is available only for functions
06 and 16). In this case all instruments receive the message and take action on the request, but do not issue a
response. In the PM172EH, the broadcast mode is supported only for register addresses 287-294 and 301-302
(reset energies and maximum demands) and 3404-3415 (reset/clear registers).

2.4 Function Field

The function field contains a function code that tells the instrument what action to perform. Function codes used in
the protocol are shown below in Table 2-2.
Table 2-2 Modbus Function Codes
Code Meaning in Modbus Action
(decimal)
03 Read holding registers Read multiple registers
04 Read input registers Read multiple registers
06 Preset single register Write single register
16 Preset multiple registers Write multiple registers
08 Loop-back test Communications test

NOTE Broadcast mode available only for functions code 06 and 16.

2.5 Data Field

The data field contains information needed by the instrument to perform a specific function, or data collected by
the instrument in response to a query.

IMPORTANT Fields composed of two bytes are sent in the order high byte first, low byte second.

5
2.6 Error Check Field
The error check field contains the Cyclical Redundancy Check (CRC) word. For detailed information about CRC
calculation, refer to the “Modicon Modbus Protocol Reference Guide”. It can be downloaded from the Modicon’s
Web site at www.modicon.com.

4 PROTOCOL IMPLEMENTATION
4.1 Modbus Register Addresses
The PM172EH Modbus registers are referred to by using addresses in the range of 0 to 65535. From within the
Modbus applications, the PM172EH Modbus registers can be accessed by simulating holding registers of the
Modicon 584, 884 or 984 Programmable Controller, using a 5-digit “4XXXX” or 6-digit “4XXXXX” addressing
scheme. To map the PM172EH register address to the range of the Modbus holding registers, add a value of
40001 to the PM172EH register address. When a register address exceeds 9999, use a 6-digit addressing
scheme by adding 400001 to the PM172EH register address.

4.2 Data Formats

The PM172EH uses three data formats to pass data between a master application and the instrument: a 16-bit
integer format, a 32-bit modulo 10000 format, and a 32-bit long integer format.

4.2.1 16-bit Integer Format

A 16-bit data is transmitted in a single 16-bit Modbus register as unsigned (UINT16) or signed (INT16) integer
(whole) numbers without conversion or using pre-scaling to accommodate large-scale and fractional numbers to a
16-bit register format. Scaling can be made using either the LIN3 linear conversion, or decimal pre-scaling to pass
fractional numbers in integer format.

Non-scaled data
The data will be presented exactly as retrieved by the communications program from the instrument. The value
range for unsigned data is 0 to 65535; for signed data the range is -32768 to 32767.

LIN3 (Linear) Scaling

This conversion maps the raw data received by the communications program in the range of 0-9999 onto the
user-defined LO scale/HI scale range. The conversion is carried out according to the formula:
Raw _ Data × (HI − LO)
Engineering _ Units _ Value = + LO
9999
where:
Engineering_Units_Value - the true value in engineering units
Raw_Data - the raw input data in the range of 0 - 9999
LO, HI - the data low and high scales in engineering units

When data conversion is necessary, the HI and LO scales, and data conversion method are indicated for the
corresponding registers.

CONVERSION EXAMPLES
1. Voltage readings
a) Assume device settings (690V input, direct wiring): PT ratio = 1.

Voltage engineering scales (see Note 1 to Table 5-1 ):

HI = Vmax = 828.0 × PT ratio = 828.0 × 1 = 828.0V
LO = 0V

If the raw data reading is 1449 then the voltage reading in engineering units will be as follows:
Volts reading = 1449 × (828.0 - 0)/9999 + 0 = 120.0V

b) Assume device settings (wiring via PT): PT ratio = 14,400V : 120V = 120.

Voltage engineering scales:

HI = Vmax = 144.0 × PT ratio = 144 × 120 = 17,280V
LO = 0V

If the raw data reading is 8314 then the voltage reading in engineering units will be as follows:
Volts reading = 8314 × (17,280 - 0)/9999 + 0 = 14,368V

9
2. Current readings
Assume device settings: CT primary current = 200A; current input overload = 120% (6A).

Current engineering scales:

HI = Imax = CT primary current × 1.2 = 200.00 × 1.2 = 240.00A
LO = 0A

If the raw data reading is 250 then the current reading in engineering units will be as follows:
Amps reading = 250 × (240.00 - 0)/9999 + 0 = 6.00A

3. Power readings
a) Assume device settings (690V input, direct wiring): wiring configuration 4LN3; PT = 1; CT primary current = 200A.

Active Power engineering scales:

HI = Pmax = Vmax × Imax × 3 = 828.0 × (200.00 × 1.2) × 3 = 596,160W = 596.160kW
LO = -Pmax = -596.160kW

If the raw data reading is 5500 then the power reading in engineering units will be as follows:
Watts reading = 5500 × (596.160 - (-596.160))/9999 + (-596.160) = 59.682kW

If the raw data reading is 500 then the power reading in engineering units will be as follows:
Watts reading = 500 × (596.160 - (-596.160))/9999 + (-596.160) = -536.538kW

b) Assume device settings (wiring via PT): wiring configuration 4LL3; PT = 120; CT primary current = 200A.

Active Power engineering scales:

HI = Pmax = Vmax × Imax × 2 = (144 × 120) × (200.00 × 1.2) × 2/1000 = 8294kW
LO = -Pmax = -8294kW

If the raw data reading is 5500 then the power reading in engineering units will be as follows:
Watts reading = 5500 × (8294 - (-8294))/9999 + (-8294) = 830kW

If the raw data reading is 500 then the power reading in engineering units will be as follows:
Watts reading = 500 × (8294 - (-8294))/9999 + (-8294) = -7465kW

4. Power Factor readings

Power factor engineering scales:
HI = 1.000.
LO = -1.000.

If the raw data reading is 8900 then the power factor in engineering units will be as follows:
Power factor reading = 8900 × (1.000 - (-1.000))/9999 + (-1.000) = 0.78

Decimal Scaling
Decimal pre-scaling is used to accommodate fractional numbers to an integer register format. Fractional numbers
pre-multiplied by 10 in power N, where N is the number of digits in the fractional part. For example, the frequency
reading of 50.01 Hz is transmitted as 5001, having been pre-multiplied by 100. Whenever a data register contains
a fractional number, the register measurement unit is given with a multiplier ×0.1, ×0.01 or ×0.001, showing an
actual register resolution (the weight of the least significant decimal digit). To get an actual fractional number with
specified precision, scale the register value with the given multiplier. To write a fractional number into the register,
divide the number by the given multiplier.

4.2.2 32-bit Modulo 10000 Format

The short energy registers 287-294, and 301-302 are transmitted in two contiguous 16-bit registers in modulo
10000 format. The first (low order) register contains the value mod 10000, and the second (high order) register
contains the value/10000. To get the true energy reading, the high order register value should be multiplied by
10,000 and added to the low order register.

10
4.2.3 32-bit Long Integer Format
In a 32-bit long integer format, data is transmitted in two adjacent 16-bit Modbus registers as unsigned (UINT32)
or signed (INT32) long integer (whole) numbers. The first register contains the low-order word (lower 16 bits) and
the second register contains the high order word (higher 16 bits) of the 32-bit long number. The low-order word
always starts at an even Modbus address. The value range for unsigned data is 0 to 4,294,967,295; for signed
data the range is -2,147,483,648 to 2,147,483,647.

A 32-bit data can be transmitted without conversion as is, or by using decimal pre-scaling to transform fractional
numbers to an integer format as described above (see Decimal Scaling in Section 4.2.1).

4.3 User Assignable Registers

The PM172EH contains the 120 user assignable registers in the address range of 0 to 119 (see Table 4-1), any of
which you can map to either register address accessible in the instrument. Registers that reside in different
locations may be accessed by a single request by re-mapping them to adjacent addresses in the user assignable
registers area.

The actual addresses of the assignable registers which are accessed via addresses 0 to 119 are specified in the
user assignable register map (see Table 4-2). This map occupies addresses from 120 to 239, where map register
120 should contain the actual address of the register accessed via assignable register 0, register 121 should
contain the actual address of the register accessed via assignable register 1, and so on. Note that the assignable
register addresses and the map register addresses may not be re-mapped.

To build your own register map, write to map registers (120 to 239) the actual addresses you want to read from or
write to via the assignable area (0 to 119). Note that long word registers should always be aligned at even
addresses. For example, if you want to read registers 7136 (real-time voltage of phase A, word) and 7576/7577
(kWh import, long word) via registers 0-2, then do the following:
- write 7576 to register 120
- write 7577 to register 121
- write 7136 to register 122
Reading from registers 0-2 will return the kWh reading in registers 0 (low word) and 1 (high word), and the voltage
reading in register 2.

4.4 Configuring and Accessing Log Files

Configuring Memory for Logging
To use the onboard data logging, allocate a separate log partition for each specific data you want to be recorded
in your instrument. The PM172EH provides concurrent recording data in 12 different memory partitions, one of
which is intended to record event log data, two partitions - for waveform recording, and the others to store 8
different data logs using different sets of data parameters. Additionally, the two last data logs #7 and #8 can be
configured to automatically record TOU monthly and daily profile data respectively using season TOU tariffs.
Refer to Section 5.19 for information on how to allocate a memory partition for your specific data. Refer to Section
5.20 on how to configure a set of parameters to be recorded to each data log.

11
Each memory partition you allocated for logging is organized as a sequential file of records where all data is
recorded in chronological order with a time and date stamp. When a partition is filled up, recording can be stopped
or can continue over the oldest records if you specified a partition with a wrap-around (circular) attribute. TOU
profile log partitions are automatically configured as wrap-around.

Each record within a log file has a unique sequence number that guards against missing or duplicated records
when reading the log file. This number is incremented (modulo 65536) with each log and will not be replicated
within the following 65535 logs. If a record is missing because of a communication problem, the read sequence for
the log can be restored from the record with the desired sequence number.
Accessing Log Files
Each log file has a separate file read pointer which always points to the current file record that will be read next,
and a separate register window which gives access to the record pointed to by this pointer. Initially, the read
pointer is associated with the oldest record in the file. Reading a record via the file window returns the current
record data, and then the pointer automatically advances to the following record in the file. Consequent requests
addressed to the file window will return a new record each time in the direction from the oldest record to the more
recent records. Because the file window advances automatically after the instrument responds to the master
request (regardless of the number of registers in the window being accessed), the entire window must be read at
once using a single request.

After the last record of the file has been read, the file read pointer is automatically shifted to the beginning of the
file. Using circular read requests always allows you to read the entire log file regardless of the current file status.
You can simply poll the file window registers just as you poll ordinal data in your SCADA applications, without the
need to manipulate the file pointer. Refer to Sections 5.29, 5.30 and 5.31 for information on read requests you can
use to access your log files.

A log file can be read both in an arbitrary order and in sequence as explained above. To access the log records in
a random order, the file read pointer can be re-written with the desired sequence number to point to the desired
record. Refer to Sections 5.5 and 5.6 for information on how to check the log file status and how to re-write the file
read pointer. Writing to the memory partition command register (see Section 5.6) allows you to force the file
pointer to point to the oldest record in the file or to the first new, unread record in the file. You can also use the
instrument reset registers (see Section 5.7) to restore the file read pointer to the oldest record in your log file if you
want to re-read the file from the beginning.

IMPORTANT: Take into consideration the fact that in a wrap-around (circular) log partition, the oldest records may
be overwritten by the most recent records since you have read either log status register. An attempt to point to the
particular record directly by using its sequence number may fail if the addressed record has just been overwritten.

4.5 Password Protection

The PM172EH has a password protection option allowing you to protect your setups, cumulative registers and
logs from being changed or cleared through communications. You can disable or enable password protection for
communications via the front panel. For details, refer to your instrument Installation and Operation Manual. When
password protection is enabled, the user password you set in your instrument should be written into the
communications password register (see Section 5.23) before another write request will be issued. If the correct
password is not supplied while password protection is enabled, the instrument will respond to all write requests
with the exception code 01 (illegal operation). It is recommended to clear the password register after you have
completed your changes in order to activate password protection.

1 The parameter limits are as follows:

 Imax (×120% over-range) = 1.2 × CT primary current [A]
Direct wiring (PT Ratio = 1):
Vmax (690 V input option) = 828.0 V
Vmax (120 V input option) = 144.0 V
Pmax = (Imax × Vmax × 3) [kW x 0.001] if wiring mode is 4LN3 or 3LN3
Pmax = (Imax × Vmax × 2) [kW x 0.001] if wiring mode is 4LL3, 3OP2, 3DIR2, 3OP3, 3LL3 or 2LL1
NOTE: Pmax is rounded to whole kilowatts. If Pmax is greater than 9,999,000 W, it is truncated to 9,999,000 W.
Wiring via PTs (PT Ratio > 1):
Vmax (690 V input option) = 144 × PT Ratio [V]
Vmax (120 V input option) = 144 × PT Ratio [V]
Pmax = (Imax × Vmax × 3)/1000 [MW x 0.001] if wiring mode is 4LN3 or 3LN3
Pmax = (Imax × Vmax × 2)/1000 [MW x 0.001] if wiring mode is 4LL3, 3OP2, 3DIR2, 3OP3, 3LL3 or 2LL1
2 When using direct wiring (PT Ratio = 1), voltages are transmitted in 0.1 V units, currents in 0.01 A units, and powers in
0.001 kW/kvar/kVA units. For wiring via PT (PT Ratio > 1), voltages are transmitted in 1V units, currents in 0.01 A units,
and powers in 0.001 MW/Mvar/MVA units.
3 Positive readings of kvarh net
4 Negative readings of kvarh net
5 To get block interval demand readings, specify the number of demand periods equal to 1 (see Table 5-19)
6 When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, they will be
line-to-line voltages.

NOTE: Writing a zero to one of registers 280-286 causes reset of all maximum demands. Writing a zero to one of registers
287-294 and 301-302 causes reset of all accumulated energies. This does not apply to the TOU system registers.

5.2 Extended Data Registers (16/32-bit)

The following table lists all registers containing the data measured by the instrument. Notice that these registers
are arranged into groups, which are not located at adjacent addresses. You can re-map these registers into
adjacent addresses to access multiple data from different data groups by using a single request. Refer to Section
4.3 for information on the user assignable registers. All data can be read either as 16-bit unsigned integer
numbers using LIN3 conversion to get true values in engineering units, or as 32-bit long signed or unsigned
integer numbers with scaling using multipliers to transmit fractional numbers. Note that in both cases, pulse and
energy counters are transmitted as 32-bit unsigned long integers.

Along with the register address, the table shows for each data item its point identifier (ID). This is a one word
containing a data group ID in the high byte and the parameter offset in a group in the low byte. Data IDs are used
to specify input or output parameters whenever a data parameter specification is needed.

1 For the parameter limits, see Note 1 to Table 5-1.
2 When using direct wiring (PT Ratio = 1), voltages are transmitted in 0.1 V units, currents in 0.01 A units, and powers in
0.001 kW/kvar/kVA units. For wiring via PTs (PT Ratio > 1), voltages are transmitted in 1V units, currents in 0.01 A units,
and powers in 1 kW/kvar/kVA units.
3 The actual frequency range is 45.00 - 65.00 Hz.
4 Absolute min/max value (lag or lead).
5 The exported energy registers are read as positive unsigned long (32-bit) integers.
6 When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, they will be
line-to-line voltages.
7 When the 4LN3, 4LL3 or 3LN3 wiring mode is selected, the harmonic voltages will be line-to-neutral; for any other wiring
mode, they will be line-to-line voltages. The line-to-line harmonic voltages in the 3DIR2, 3LL3 and 2LL1 wiring modes, and the
L31 harmonic voltage in the 3OP2 and 3OP3 wiring modes will be calculated accurately if the voltages are balanced.
8 Harmonic angles are referenced to the fundamental voltage harmonic H01 on the same phase.
(M) These parameters are logged to the Min/Max log

The setpoint alarm register stores the status of the operated setpoints by setting the appropriate bits to 1. The
alarm status bits can be reset all together by writing zero to the setpoint alarm register. It is possible to reset each
alarm status bit separately by writing back the contents of the alarm register with a corresponding alarm bit set to
0.

The self-check alarm register indicates possible problems with the instrument hardware or setup configuration.
The hardware problems are indicated by the appropriate bits which are set whenever the instrument fails self-test
diagnostics or in the event of loss of power. The setup configuration problems are indicated by the dedicated bit
which is set when either configuration register is corrupted. In this event, the instrument will use the default
configuration. The configuration corrupt bit may also be set as a result of the legal changes in the setup
configuration since the instrument might implicitly change or clear other setups if they are affected by the changes
made.

Hardware fault bits can be reset by writing zero to the self-check alarm register. The configuration corrupt status
bit and RTC synchronization bit are also reset automatically when you change setup or update RTC either via the
front panel or through communications.

Zero scale (0-4 mA) +1 UINT16 R/W see Table 5-26
Full scale (1/20 mA) +2 UINT16 R/W see Table 5-26

1. Except for the signed power factor (see Note 3 to Table 5-26), the output scale is linear within the value range. The
scale range will be inverted if the full scale specified is less than the zero scale.
2. For bi-directional analog output (±1 mA), the zero scale corresponds to the center of the scale range (0 mA) and the
direction of the current matches the sign of the output parameter. For signed (bi-directional) values, such as powers
and signed power factor, the scale is always symmetrical with regard to 0 mA, and the full scale corresponds to +1
mA output for positive readings and to -1 mA output for negative readings. For these, the zero scale (0 mA output) is
permanently set in the instrument to zero for all parameters except the signed power factor for which it is set to
1.000. In the write request, the zero scale is ignored. No error will occur when you attempt to change it. Unsigned
parameters are output within the current range 0 to +1 mA and can be scaled using both zero and full scales as in
the case of single-ended analog output.

2 When using direct wiring (PT Ratio = 1), voltages are transmitted in 0.1 V units, currents in 0.01 A units, and powers in
0.001 kW/kvar/kVA units. For wiring via PTs (PT Ratio > 1), voltages are transmitted in 1V units, currents in 0.01 A units,
and powers in 1 kW/kvar/kVA units.
3 The actual frequency range is 45.00 to 65.00 Hz.
4 The output scale for signed (bi-directional) power factor is symmetrical with regard to ±1.000 and is linear from -0 to
-1.000, and from 1.000 to +0 (note that -1.000 ≡ +1.000). Negative power factor is output as [-1.000 minus measured
value], and non-negative power factor is output as [+1.000 minus measured value]. To define the entire range for power
factor from -0 to +0, the scales would be specified as -0/0. Because of the fact that negative zero may not be transmitted,
the value of -0.001 is used to specify the scale of -0, and both +0.001 and 0.000 are used to specify the scale of +0. To
define the range of -0 to 0, you must send -0.001/0.001 or -0.001/0.
5 When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, they will be
line-to-line voltages.

2. When writing the setpoint registers (except the event when the setpoint is to be disabled), it is recommended to write
all the setpoint registers using a single request, or disable the setpoint before writing into separate registers. Each
value being written is checked for compatibility with the other setpoint parameters; if the new value does not conform
to these, the request will be rejected.

3. Operate and release limits for the trigger parameters and their conversion scales are indicated in Table 5-29. Each
limit value occupies two contiguous registers, the first of which (low word) contains the limit value, and the second
(high word) is reserved for long parameters. This register is always read as zero. When written, its value is ignored.

4. Limits indicated in Table 5-29 by a N/A mark are read as zeros. When writing, they can be omitted or should be
written as zeros.

5. When a setpoint action is directed to a relay allocated to output energy pulses, an attempt to re-allocate it for a
setpoint will result in a negative response.

2 When using direct wiring (PT Ratio = 1), voltages are transmitted in 0.1 V units, currents in 0.01 A units, and powers in
0.001 kW/kvar/kVA units. For wiring via PTs (PT Ratio > 1), voltages are transmitted in 1V units, currents in 0.01 A units,
and powers in 1 kW/kvar/kVA units.
3 The setpoint is operated when the actual phase sequence does not match the indicated phase rotation.
4 The actual frequency range is 45.00 - 65.00 Hz.
5 When the 4LN3 or 3LN3 wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, they will be
line-to-line voltages.
6 Operate limit for the voltage disturbance trigger specifies the voltage deviation allowed in percentage of the nominal
secondary line-to-line voltage. The tested voltage refers to line-to-line voltage in 3OP2 and 3OP3 wiring modes, and to line-
to-neutral voltage in other modes. See Section 5.8, Basic Setup, for information on setting the nominal voltage in your
meter.

NOTES
1. A relay allocated as a pulsing relay may not be manually operated or released. When a relay is allocated
for pulsing, it automatically reverts to normal operation.
2. A relay is energized when manually operated, and is de-energized when manually released.

These registers allow you to allocate a memory partition for logging and to specify the partition size and type. Before allocating
a partition, it is recommended to check the available memory by reading the extended memory status registers. To help you in
planning memory, Table 5-44 shows the record size for each partition.

42
Note that the existing partition may not be resized. To change the partition properties, you should first delete a partition and
then reallocate it with the desirable properties. To delete a partition, write zero into the first partition's register.

Data log partitions #7 and #8 can be configured as TOU monthly and daily profile log partitions respectively. Both will be set as
wrap-around partitions. Before you configure the partition as a profile partition, set up your TOU registers, daily profiles and
calendars. The memory for a profile log is allocated automatically in accordance with the number of TOU registers you defined
in the TOU setup. For each TOU energy and maximum demand register, a separate log sub-partition will be allocated within a
parent log partition. Each of these can be accessed and read individually (see Section 5.24). The number of log parameters in
the record should specify the maximum number of active season tariffs. The file record size will be set in accordance with this
number. If you specified it as less than the actual number of tariffs that may be in effect within a tariff season, then only part of
the tariff registers will be recorded to the profile.
When allocating a memory partition, all partition registers must be written at once using a single request. After reallocation of
memory, the instrument performs the memory optimization and will not respond to the host requests for approximately 1
second per 128 Kbytes of memory.

Writing into registers at offsets +3, +4 and +5 does not affect the register contents. No error will occur.

1. Parameters that can be selected for data log are listed in Table 5-2. Before setting up the parameters for any data log, the
memory partition must be allocated for the log (see Section 5.19). When writing the data log setup registers, only
parameters that are specified in the partition record setup will be written. When reading registers, those that are not defined
in the data log setup will be read as zeros.
2. If a partition has been allocated as a TOU profile log partition, the data log setup for the partition cannot be written. Write
requests will be ignored. A read request will return identifiers of the TOU season tariff energy registers 28672 to 28687.

5.29 Event Log Registers
These registers allow you to circularly read a packet of consequent records from the event log file. From 1 to 12
event log records can be read at a time via the event log windows, which comprise registers 29440 through
29559. Reading from either register window always returns the next logged event record. All registers within one
window must be read at once using a single request. After reading an event log window, the partition queue
pointer is shifted forward until the end of the log file. After the last record has been read, the file pointer is
automatically restored to the beginning of the log file so that the next read request will return the first (oldest)
event. To point to an arbitrary record, use the log partition status/control registers (see Section 5.6).

5.30 Data Log Registers

These registers allow you to circularly read consequent records from the event log file. Each data log file is
accessed via a separate register window. Reading from either register window always returns the next logged
record from the corresponding data log. All registers within one window must be read at once using a single
request. After reading a log window, the partition queue pointer is shifted forward until the end of the log file. After
the last record has been read, the file pointer is automatically restored to the beginning of the log file so that the
next read request will return the first (oldest) record. To point to an arbitrary record, use the data log partition
status/control registers (see Section 5.6).

point in the waveform record.

To convert digital samples to their analog equivalents in input measurement units (volts, amps), the following scaling should be
applied:
(DIGITAL _ SAMPLE − ZERO _ OFFSET ) × ANALOG _ SCALE × 2
ANALOG _ SAMPLE [ Volts / Amps ] =

Through these registers you can capture and read the real-time waveforms (4 cycles x 128 samples per cycle),
and the recorded historical waveform logs - the Waveform log #1 (16 cycles x 32 samples per cycle records), and
the Waveform log #2 (4 cycles x 128 samples per cycle records). The waveform samples are read via the register
window 6144-6655 (see Table 5-71) that can map a record for a single input channel (voltage or current waveform
on either phase). To reload this window with a sampled waveform, a corresponding waveform header window
should be accessed (see Table 5-69).

Real-time Waveform Capture

The real-time waveforms can be captured simultaneously on both voltage and current channels for a single phase.
To capture two waveforms on a selected phase, the first register (at offset +0) in the voltage waveform header
window for this phase (register 35456, 35472, or 35488) should be accessed by reading this register or by reading
the entire header window. Before responding to your request, the instrument reloads both the waveform header
and waveform samples window with data corresponding to the voltage waveform. Data in these windows does not
change until the first (command/status indication) register in either of the waveform header windows is read.

To reload the waveform header and samples windows with the current waveform data, read the first register in the
current waveform header window for the same phase.

To capture and read waveform data on another phase, repeat the above steps for the phase you want to access.

Historical Waveform Logs

The historical waveform logs contain waveform records sampled at high (128 samples per cycle in Waveform log
#2) or lower frequency (32 samples per cycle in Waveform log #1) that are captured and logged to a file on some
event triggers. Each record contains six waveforms of voltage and current on three phases.

Recorded waveforms are mapped and accessed through register windows in the same manner as the real-time
waveforms (see above). On log files organization and managing, see Section 4.4, Configuring and Accessing Log
Files. Before reloading waveform window registers with data for a selected channel, the required record must be
obtained from the log file to the communications buffer. This is made automatically when you reload the voltage
waveform on phase L1, i.e., when you read the register at offset +0 in the voltage waveform header on phase L1
for the corresponding log file (registers 35552, 35648). Data in this buffer does not change until you read this
register once again. Each time you access this register, the next record is read form the file and locked to the
communications buffer. To reload waveform windows with data for the current channel or with data for another
phase, read the command/status indication register in the voltage or current header window for the corresponding
channel.

Waveform log files are accessed in a circular manner. When the last record in the file is being read, bit 0 in the
status indication register in the waveform header windows is set to 1. If you continue reading after the end of a file,
the file pointer rolls over to the beginning of the file and the first (oldest) record is returned with bit 1 in the status
indication register being set to 1.
