1 GENERAL

This document specifies a subset of the Modbus serial communications protocol used to
transfer data between a master computer station and the PM130. The document provides the
complete information necessary to develop a third-party communications software capable of
communication with the Series PM130 Powermeters. Additional information concerning
communications operation, configuring the communications parameters, and communications
connections is found in "Series PM130 Powermeters, Installation and Operation Manual".

IMPORTANT

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.
Most of the instrument 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.

Specification changes

The following indicates specification changes which apply to PM130 instruments with firmware
version 3.54 or later:
Added 32-bit long integer format for extended data registers (see Sections 4.2 and 5.8).

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 c 8
Parity (optional) 1
Stop bit 1

Least significant bit first

c

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 PM130, the
broadcast mode is supported only for register addresses 287-294 and 301-302 (reset energies
and maximum demands), 3404-3415 (reset/clear registers), and 4352-4358 (real-time clock
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.

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.

2.6 Error Check Field

The error check field contains the Cyclical Redundancy Check (CRC) word. The start of the
message is ignored in calculating the CRC. The CRC-16 error check sequence is implemented
as described in the following paragraphs.

The message (data bits only, disregarding start/stop and optional parity bits) is considered one
continuous binary number whose most significant bit (MSB) is transmitted first. The message is
pre-multiplied by x
binary number (11000000000000101). The integer quotient digits are ignored and the 16-bit
remainder (initialized to all ones at the start to avoid the case of all zeros being an accepted
message) is appended to the message (MSB first) as the two CRC check bytes. The resulting
message including CRC, when divided by the same polynomial (x
receiver will give a zero remainder if no errors have occurred. (The receiving unit recalculates
the CRC and compares it to the transmitted CRC). All arithmetic is performed modulo two (no
carries).

The device used to serialize the data for transmission will send the conventional LSB or right­most bit of each character first. In generating the CRC, the first bit transmitted is defined as the
MSB of the dividend. For convenience, and since there are no carries used in the arithmetic,
let's assume while computing the CRC that the MSB is on the right. To be consistent, the bit
order of the generating polynomial must be reversed. The MSB of the polynomial is dropped
since it affects only the quotient and not the remainder. This yields 1010 0000 0000 0001 (Hex
A001). Note that this reversal of the bit order will have no effect whatever on the interpretation
or bit order of characters external to the CRC calculations.

The step by step procedure to form the CRC-16 check bytes is as follows:

1. Load a 16-bit register with all 1's.

2. Exclusive OR the first 8-bit byte with the low order byte of the 16-bit register, putting the
result in the 16-bit register.

3. Shift the 16-bit register one bit to the right.

4a. If the bit shifted out to the right (flag) is one, exclusive OR the generating polynomial 1010

000 000 0001 with the 16-bit register.

4b. If the bit shifted out to the right is zero, return to step 3.

5. Repeat steps 3 and 4 until 8 shifts have been performed.

6. Exclusive OR the next 8-bit byte with the 16-bit register.

7. Repeat step 3 through 6 until all bytes of the message have been exclusive ORed with the
16-bit register and shifted 8 times.

8. When the 16-bit CRC is transmitted in the message, the low order byte will be transmitted
first, followed by the high order byte.

For detailed information about CRC calculation, refer to the Modbus Protocol Reference Guide.

4 PROTOCOL IMPLEMENTATION

4.1 Modbus Register Addresses

The PM130 Modbus registers are referred to by using addresses in the range of 0 to 65535.
From within the Modbus applications, the PM130 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 PM130 register address
to the range of the Modbus holding registers, add a value of 40001 to the PM130 register
address. When a register address exceeds 9999, use a 6-digit addressing scheme by adding
400001 to the PM130 register address.

4.2 Data Formats

The PM130 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 or signed 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:

Y = (X / 9999) × (HI - LO) + LO

where:
Y - the true value in engineering units
X - 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.

EXAMPLE
Suppose you have read a value of 5000 from register 256 that contains a voltage reading (see
Table 5-1). If your instrument has the 144V input option, and you use potential transformers

with the ratings of 22,000V : 110V = 200, then the voltage high scale is HI = 144×200 = 28,800,

and in accordance with the above formula, the voltage reading in engineering units will be as
follows:

5000 × (28800 - 0)/9999 + 0 = 14401V

When a value is written to the instrument, the conversion is carried out in reverse to produce
the written value in the range of 0 - 9999:

X = 9999 × (Y - LO) / (HI - LO)

10

Decimal Scaling
Decimal pre-scaling can be 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.

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 or signed 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 PM130 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.

zero to this location will simulate an external synchronization pulse denoting the start of the next
demand interval. The synchronization requests should not follow in intervals of less than 30
seconds, or the request will be rejected.

2) If the power demand period is specified in minutes, writing a zero to this location provides
synchronization of the instrument’s internal timer with the time of reception of the master’s request. If the
time expired from the beginning of the current demand interval is more than 30 seconds, the new demand
interval starts immediately, otherwise synchronization is delayed until the next demand interval.

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 is also reset automatically when you change setup either via the
front panel or through communications.

5.8 Extended Data Registers

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 2.9 for information on the user assignable
registers.

Along with the register address, the table shows for each data item its data 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, for example, when selecting analog output parameters or
reading Min/Max log records.

The setpoint is disabled when its trigger parameter is set to NONE. To disable the setpoint,
write zero into this register.
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.
Operate and release limits for the trigger parameters and their conversion scales are indicated
in Table 5-18. 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.
Limits indicated in Table 5-18 by a N/A mark are read as zeros. When writing, they can be
omitted or should be written as zeros.
When a setpoint action is directed to a relay allocated to output energy pulses, an attempt to re­allocate it for a setpoint will result in a negative response.

5.11 Relay Operation Control

These registers allow the user to manually override a relay operation that is normally operated
via alarm setpoints.

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.

5.12 Min/Max Log

The Min/Max log registers are supported only for compatibility with other models of instruments.
Because the Min/Max log is not time stamped in the PM130, reading these registers returns you
only values of the Min/Max log parameters which you can read directly via extended data
registers (see Table 5-15).

type. For the value length and conversion scales, refer to Table 5-15. The time stamp is not
available in the PM130 and is read as zeros.

ID for window #1

From 1 to 12 adjacent Min/Max log records can be read at a time via the Min/Max log windows. The
starting window #1 can be mapped to any Min/Max log parameter listed in Table 5-15 by writing the
parameter ID to the Min/Max log mapping register. This must be written before reading the Min/Max log
windows. Note that through Min/Max log windows, you can read only adjacent parameters within the same
Min/Max log data group. Reading parameters outside of the selected Min/Max log data group will return
zero.
