1 GENERAL

This docume nt specifies a subs et of the Modbus ser ial com munications protocol used to transfe r data between a master comp uter sta tion and the PM171. T he docum ent pr ovides the com plete infor matio n necessary to develop a third-party comm unicat ions sof tware capable of com m unic ation with the Series PM171 Powermeters. Additional information concerning communications operation, configuring the communications parameters, and communications connections is found in "Series PM171 Powermeters, Installation and Operation Manual".

IMPORTANT

1. The voltage parameters throughout the protocol can represent line-to-neutral or line-to-line voltages depending on the wiring mode selected in the instrument. 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. In 4LN3, 4LL3, 3LN3 and 3LL3 wiring modes, harmonic voltages will represent line-to-neutral voltages. In a 3-wire direct connection, harmonic voltages will represent line-to-neutral voltages as they appear on the instrument's input transformers. In a 3-wire open delta connection, harmonic voltages will comprise L12 and L23 line-to-line voltages.

2. 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.

3. Most of the inst rument 's advanc ed fe atures a re configu red usi ng multi ple setu p parame ters that can be accessed in certain 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.

2 MODBUS FRAMING

2.1 Transmission Mode

The protocol us es t he M odbus Remote Terminal Unit ( RT U) t rans mission mode. In RTU m ode, dat a is sent in 8-bit binary character s. The 8 bit even parity or 8 bit no parity data format mu st be selected when configuring the instrument communicat ions. The data format is shown in the following table.

Table 2-1 RTU Data Format

Field No. of bits

Start bit 1 Data bits  8 Parity (optional) 1 Stop bit 1



Least significant bit first

2.2 The RTU Frame Format

Frame synchronization is maintained in RTU transmission mode by simulating a synchronization message. T he receiving device m onitors the elaps ed time between receptions o f 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 def ined 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. I n the PM171, the broadcast mode is supporte d only for register address es 287- 294 and 301-302 ( reset ener gies and m ax imum dem and s), 3404- 3415 (reset/clear registers), and 4352-4358 (real-time clock registers).

2.4 Function Field

The function field contains a f unction code that tells the instr ument what action to perf orm. Function codes used in the protocol are shown below in Table 2-2.

Meaning in Modbus Action

2.5 Data Field

The data field c ontains information needed by the instrum ent to perform a spec ific 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 c heck f ield contains the Cyclical Redundancy Check (CRC) word. T he start of the m essage 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 num ber whose m ost significant bit (MSB) is transmit ted first. The m essage is premultiplied by x 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 m essage (MSB fir st) as the two CRC c heck bytes. The r esulting messa ge including CRC, when divided by the same polynomial (x remainder if no error s have oc curred. (The receiving unit rec alculates th e CRC and comp ares it to the transmitted CRC). All arithmetic is performed modulo two (no carries).

The device used to serialize the data f or trans mission will s end the conventiona l LSB or right-most bit of each char acter first. In generating the CRC, the firs t bit transmitted is defined as the MSB of the dividend. For convenien ce, and since ther e are no carries used in t he arithmetic, let's ass ume while computing the CRC that the MSB is on the right. To be consistent, the bit order of the generating polynomial must be r eversed. The MSB of the polynomial is drop ped since it affe cts only the quotient and not the rem ainder. T his yields 101 0 0000 0000 000 1 (Hex A001). Not e that th is reversal of the bit order will have no effect whatever on the int erpretation or bit order of cha racters ext ernal 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 byt e of the 16-b it regist er, putti ng the resu lt in the 16- bit

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

4a. If the bit shi fted out to the right (flag) i s one, exclusive OR the generating polyno mial 1010 000 000 00 01

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. W h en 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 Mod bus Pr otocol Reference Guide.

4 PROTOCOL IMPLEM ENTATION

4.1 Modbus Register Addresses

The PM171 Modbus register s are referred to by using addresses in the range of 0 to 65535. From within the Modbus applications, the PM171 Modbus r egisters can be access ed by simulating holding registers of th e Modicon 584, 88 4 or 984 Program mable Cont roller, using a 5-digit “4XX XX” or 6-digit “4XXXXX” addressing scheme. To map the PM171 register address to the range of the Modbus holding registers, add a value of 40001 to the PM171 register address. When a register address exceeds 9999, use a 6-digit addr essing scheme by adding 400001 to the PM171 register ad dr ess.

4.2 Data Formats

The PM171 uses thr ee data f ormats to pass data b etween a mast er application and the instru ment: 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 tr ansmitted in a single 16- bit Modbus register as unsigne d or signed integer (whole) numbers without co nversion or using p re-scaling to a ccomm odate large-sca le and fractional num bers to a 16-bit r egister format. Scaling can be made using either the LIN 3 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 instrumen t. The value range for unsigned data is 0 to 65535; for signed data the range is -32768 to 32767.

LIN3 (Linear) Scal i ng

This convers ion m aps the r aw data rece ived by the com munic ations pro gram in the rang e of 0 - 9999 onto the user-defined LO scale/HI scale range. The conversion is carried out according to the f or mula:

Y = (X / 9999) × (HI - LO) + LO

where: Y - the true value in en gi neering units X - the raw input data i n the range of 0 - 9999 LO, HI - the data low and high scales in engineering units

When data convers ion is nece ssary, the HI and LO sc ales, and data convers ion metho d are indicated for the corresponding r egisters.

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 vo l tage 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 convers ion is carried out in reverse to produce the written value in the range of 0 - 9999:

X = 9999 × (Y - LO) / (HI - LO)

Decimal Scaling

Decimal pre-s caling can be used to accom modate fractional numbe rs to an integer register forma t. Fractional num bers pre-mu ltiplied by 10 in power N, where N is the num ber of digits in the fractional part. For example, the frequency reading of 50.01 Hz is transmitted as 5001, having been premultiplied by 100. W henever a data register c ontains a fractional num ber, the register m easurement unit is given with a m ultiplier ×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 g iven multiplier. To write a f r act ional nu m b er into the reg ister , divide the number by the given multiplier.

4.2.2 32-bit Modulo 10000 Format

The short energ y registers 287-294, a nd 301-302 are transm itted in two contiguous 16-bit r egisters in modulo 10000 f ormat. The firs t (low order) register contains the value m od 10000, and the second (high order) register c ontains the value/10000. T o get the tru e energy reading, the high order regis ter 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 inte ger f orm at, dat a is transm it ted in two adjac ent 16-b it Modbus regis ters as uns igne d or signed long integer (whole) numbers. The first register contains the low-order word (lower 16 bits) and the second reg ister contains the high or der word (higher 16 bits) of the 32-bit long num ber. The low-order word always starts at an even M odbus address. T he value range for unsigned d ata is 0 to 4,294,967,295; f or signed data the range is -2,147,483,648 to 2,147,483,647.

A 32-bit data can be transmit ted without convers ion as is, or by using decimal pre-sc aling to transfor m fractional num bers to an integer format as described above (see Decimal Scaling in Section 4.2.1).

4.3 User Assignable Registers

The PM171 contains th e 120 user assignable registers in t he address range of 0 to 119 (see Table 4-1), any of which you can map to either re gister address access ible in the instr ument. Reg isters 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 u ser as signable registe r map (s ee Table 4-2) . This m ap occupies addr esses f rom 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 address es and the map register addresses may not be re-mapped.

To build your own register m ap, write to m ap registe rs (120 to 239) the actual ad dresses 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. Fo r example, if you want to re ad register s 7136 (real -time voltage of phase A, word) and 757 6/7577 (kWh import, long word) via registers 0-2, then do the following:

- write 7576 to register 120

- write 7577 to register 1 21

- 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 o nboar d data lo gging, alloca te a se para te log par tition f or each spec ific data you want to be recorded in your instrum ent. The PM171E provides conc urrent recording data in 9 dif ferent memory partitions, one of which is intended to record event log data and the others to store 8 different data logs using different sets of data parameters. Refer to Section 5.18 for information on how to allocate a memory partition for your sp ecific dat a. Refer to Sectio n 5.19 on how to conf igure a set of param eters to be recorded to each data log.

Each memor y partition you allocated for logging is or ganized 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.

Accessing Log Files

Each log file has a separa te file read pointer which always points to the current file record that will be read next, a nd a s eparate re gister window whic h gives acc ess t o the rec ord pointe d to by this point er. Initially, the read pointer is as sociated with the oldest rec ord in the file. Reading a re cord via the file window returns the cu rrent record data, and t hen the pointer automat ically advances to the following record in the file. Consequen t requests add ress ed to the f ile window will return a new record each time in the direction from the oldest record t o the more recent recor ds. Because the f ile 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.

The instrum ent provides sequential readin g of a file records unt il the end of a file is reac hed. W hen a record is requested after the end of a file, the re sponse message will contain a zero record with an exception code indicating th e end of a log file. Refer to Sections 5.20 and 5.21 f or inform ation on rea d requests you can use to access your log files .

You can also use the instrum en t res et regist ers ( see Section 5. 5) to rest ore t he file read po inter t o the oldest record in your log file if you want to re-read the file fr om the be ginning. Tak e into consideratio n the fact that in a wr ap- aro und ( c ircu lar) log par tition, the oldes t recor ds may be overwritten by the most recent records s ince you have read them.

The self-chec k alarm regist er indicates p ossible problem s with the instrumen t hardware or setup config uration. The hardware problems are indicated by the appropriate bits which are set whenever the instrument fails self-test diagnostics or in the event o f loss of power. The setu p config uration problems are indicat ed by the dedi cated bi t 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 res et by writing zero to the sel f-check alarm re gister . The config uration corrupt s tatus bit and RTC synchronization bit are also reset automatically when you change setup or update RTC either via the front panel or through communications.

5.9 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 reques t. 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 un its, or as 32-bit long signed or unsigned integer numbers with scaling usi ng multipli ers to transm it fraction al numbers . Note that in both cases, pulse and energy counters are transmitted as 32-bit unsigned long intege rs.

Along with the reg ister address, the table shows for each d ata item its data id entifier (ID). This is a on e word containing a data group ID in the high byt e and the parameter off set in a group in the low byte. Data IDs are use d 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.

2. For bi-dir ection al an alog ou tput (±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 (bidirectional) values, such as powers and signed power factor, the scale is always symmetrical with regard to 0 m A, and the full scale c orresponds to +1 mA output for positive read ings 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.

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 fr om 1. 000 to +0 (n ote tha t -1.0 00 ≡ +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.

this register.

2. When writing the setpoint registers (except the event when the setpoint is to be disabled), it is

recommended to write all the setpoin t registers using a sing le request, or disable the setp oint 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.

5.16 Relay Operation Control Registers

These registers allow the user to manually override setpoint relay operations. Either relay may be manually operated or released using commands sent via communications.

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 alloca ting a par titio n, it is recom men ded to che ck t he avail able m emor y by readin g the extend ed memo ry status registers. To help you in planning memory, Table 5-41 shows the rec ord size for each partition .

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.

When allocating a memory partiti on, all partitio n registers must be written a t once using a sing le 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 Kbyte of memory.

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

5.20 Event Log Registers

These registers allow you to read the packet of consequent records from the event log partition. From 1 to 10 event log records can be read at a time via the event log windows, which comprise registers 3916 through 4035. Reading from eith er event log window always ret urns the ne xt logg ed even t. Al l reg iste rs within on e wind ow must be read at once using a single request. After reading each record, the partition queue pointer is shifted forward until the last logged record has been read. After that, the exception code 98 is returned in the window register at offset +0. It should be c hecked befo re accept ing the recor d. To restore the queue to the orig in, a zero must be written to the event lo g queue reset register (se e Section 5.5).
