6 General This document specifies a subset of the Modbus serial communications protocol used to transfer data between a master computer station and the BFM66. The document provides the complete information necessary to develop third-party communications software capable of communication with the Series BFM66 instruments. For additional information concerning communications operation, configuring the communications parameters, and communications connections see the BFM66 Installation and Operation Manual. 6

7 Modbus Protocol Implementation For detailed information about Modbus protocol, Modbus message framing and error checking, refer to the Modbus Protocol eference Guide. It can be downloaded from the ebsite. The following paragraphs outline some issues concerning the implementation of the Modbus protocol in the BFM66.. Transmission Modes The BFM66can be set up to communicate on a serial Modbus network using either TU, or ASCII serial transmission mode, and via the Internet using ModbusTCP mode. efer to the BFM66 Installation and Operation Manual for information on selecting the transmission mode in your meter.. Address Field The address field contains a device submeter address (-7) on a Modbus network. The user assigned device address (see Communication Ports Setup in Section.7) is used as a reference address of the first device submeter. See Submeter Addressing in Section.6 for more information on device addressing. Broadcast mode using address is not supported.. Function Field The Modbus functions implemented in the BFM66 are shown in Table -. Function can be used in the same context as function. Table - Modbus Function Codes Code Meaning in Modbus Action (decimal) ead holding registers ead multiple registers ead input registers ead multiple registers 6 Preset single register rite single register 6 Preset multiple registers rite multiple registers 8 Loop-back test Communications test The BFM66 supports only diagnostic code - return query data.. Exception esponses The instrument sends an exception response when an error is detected in the received message. To indicate that the response is notification of an error, the high order bit of the function code is set to. Implemented exception response codes: - Illegal function - Illegal data address - Illegal data value - Device failure hen the character framing, parity, or redundancy check detects a communication error, processing of the master's request stops. The instrument will not act on or respond to the message.. Modbus egister Addresses The BFM66 Modbus registers are numbered in the range of to 6. From Modbus applications, the BFM66 Modbus registers can be accessed by simulating holding 7

8 registers of the Modicon 8, 88 or 8 Programmable Controller, using a -digit XXXX or 6-digit XXXXX addressing scheme. To map the BFM66 register address to the range of the Modbus holding registers, add a value of to the device register address. hen a register address exceeds, use a 6-digit addressing scheme by adding to the BFM66 register address..6 Submeter Addressing Each active submeter in the BFM66 is assigned a unique communication address that allows accessing its private registers and setups. A separate Modbus address is engaged for each submeter for which at least one current input is allocated in the Channel Assignments Setup (see Section.7), and for each additional submeter, which is allocated as a target in the BillingTOU egisters Source Setup (see Section.7). The BFM66 can occupy up to contiguous addresses starting with the device reference address. All submeter addresses are assigned automatically in a sequential order starting from the device base address that is programmed through the device Communication Setup. The following table illustrates submeter addressing in the device with the base address N. Device Base Submeter Number Submeter Address Address N SM N SM N+ SM 6 N+ SM 7 N+6 SM N+ Your device is factory preset to address and occupies the range of addresses through, configured for three-phase submeters. NOTE Device setup settings, excluding the alarm setpoints and data log setup, are shared across all submeters. Though you can readwrite them using any submeter address, your changes affect all submeters in the device. Note that the communication port setup may only be changed via the device base address. Select your submeters (both metering and totalization) in a sequence without gaps so that your device would not occupy unnecessary network addresses. If you connect a number of devices to a serial network, allocate a range of addresses for each device so that they do not overlap. For example, if you use three devices with submeters in each one, assign the base address to the first device, the address to the second, and the address to the third device so that they will occupy three non-overlapped address ranges through, through, and through 6..7 Data Formats The BFM66 uses two data formats to pass data between a master application and the instrument: 6-bit short integer and -bit long integer formats. Binary values and counters are always transmitted in -bit registers, while analog values can be read both in -bit and in 6-bit scaled registers bit Scaled Integer Format 6-bit scaled analog data is transmitted in a single 6-bit Modbus register being scaled to the range of to. To get a true reading, a reverse conversion should be done using the following formula: X (HI LO) Y = + LO 8

9 where: Y - True reading in engineering units X - aw input data in the range of to LO and HI - Data low and high scales in engineering units The engineering scales are indicated for every scaled 6-bit register. efer to Section Data Scales and Units for applicable data scales and measurement units. CONVESION EXAMPLES. Voltage readings Voltage engineering scales (see Section ): HI = Vmax = 6.V LO = V If the raw data reading is then the voltage reading in engineering units will be as follows: Volts reading = (6. - )( - ) + = 86.V. Current readings Assume device settings: CT primary current = A. Current engineering scales (see Section ): HI = Imax = CT primary current =. =.A LO = A If the raw data reading is then the current reading in engineering units will be as follows: Amps reading = (. - )( - ) + =.A. Power readings a) Assume device settings: CT primary current = A. Active Power engineering scales (rounded to whole k, see Section ): HI = Pmax = Vmax Imax = (6. ) (. ) =, = k LO = -Pmax = - k If the raw data reading is then the power reading in engineering units will be as follows: atts reading = ( - (-))( - ) + (-) =.k If the raw data reading is then the power reading in engineering units will be as follows: atts reading = ( - (-))( - ) + (-) = -.k. Power Factor readings Power factor engineering scales: HI =.. LO = -.. If the raw data reading is 8 then the power factor in engineering units will be as follows: Power factor reading = 8 (. - (-.))( - ) + (-.) = bit Long Integer Format -bit long integer data is transmitted in two adjacent 6-bit Modbus registers as unsigned (UINT) or signed (INT) whole numbers. The first register contains the low-order word (lower 6 bits) and the second register contains the high order word (higher 6 bits). The low-order word always starts at an even Modbus address. The value range for unsigned data is to,,67,; for signed data the range is -,7,8,68 to,7,8,67.

10 If your Modbus driver does not support a -bit long integer format, you can read the two 6-bit registers separately, and then convert them into a -bit value as follows (using C notation): -bit value = (signed short)high_order_register 66L + (unsigned short)low_order_register Fractional -bit data is transmitted using decimal scaling to pass fractional numbers in integer format. Fractional numbers are pre-multiplied by to the power N, where N is the number of digits in the fractional part. For example, the frequency reading of. Hz is transmitted as, having been pre-multiplied by. henever a data register contains a fractional number, the register measurement unit is given with a multiplier.,. or., showing the weight of the least significant decimal digit. To get an actual fractional number with specified precision, multiply the register value by the given multiplier. To write a fractional number into the register, divide the number by the given multiplier..8 User Assignable egisters The BFM66 contains user assignable registers in the address range of to, any of which you can map to any register address accessible in the instrument. egisters 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 through, are specified in the register map (registers through ), where register contains the actual address of the register accessed via register, register contains the actual address of the register accessed via register, and so on. The assignable registers and the map registers themselves may not be re-mapped. To build your own register map, write to map registers to the actual addresses you want to read from or write to via the assignable area (registers to ). -bit long registers should always be aligned at even addresses. For example, if you want to read registers 67 (-second V voltage, scaled short integer) and 7-7 (kh Import, long integer) via registers -, do the following: - write 7 to register - write 7 to register - write 67 to register eading from registers - will return the kh reading in registers (low 6 bits) and (high 6 bits), and the voltage reading in register.. Password Protection The BFM66 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 through communications or from the front panel display. For details, refer to your instrument Operation Manual. hen password protection is enabled, the user password you set in your instrument should be written into the device authorization register (78-7) before another write request is 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 (illegal operation). It is recommended to clear the password register after you have completed your changes in order to activate password protection.

11 . Data ecording and File Transfer.. Log File Organization Historical files are stored to the non-volatile memory. The device memory is automatically partitioned between files and does not require additional settings. Each submeter has individual historical files. Data records in a file are arranged in the order of their recording. Each record has a unique 6-bit sequence number that is incremented modulo 66 with each new record. The sequence number can be used to point to a particular record in the file, or to check the sequence of records when uploading files from the device. Each file has a write position pointer that indicates the place where the next record will be recorded, and a read position pointer that indicates the place from where the current record will be read. Both pointers show sequence numbers of the records they point to rather than record offsets in the file. After acknowledging a record you have read, the read pointer automatically advances to the next record in the file. hen the read pointer gets to the record to which the file write pointer points, the end-of-file (EOF) flag is set. It is automatically cleared when a new record is added to the file, or when you explicitly move the read pointer to any record within a file. Each file has a wrap-around attribute (circular file), the most recent records overwrites the oldest records. hen this happens at the current read position, the read pointer automatically advances forward in order to point to the oldest record in the file. The BFM66 keeps a separate read pointer for each communication port so that access to the same file through a different port will not affect current active sessions for other ports. Data Log File Data log file of each submeter can store up to 6 measured parameters per a record. The number of parameters that each record will hold and the list of parameters you want to be recorded in the file can be selected through the Data log setup registers for a particular file. ecording data to the data log file can be triggered through the setpoints on a time basis using the meter clock. BillingTOU Profile Log File Data log file #6 is automatically configured for a daily profile log of the energy usage and maximum demand registers. A profile log file is organized as a multi-section file that has a separate section for each energy and maximum demand register. A file record stores the summary data (total of all tariffs) and all tariff data for each configured BillingTOU register. See Section. for information on the file record structure. The number of sections is taken automatically from the BillingTOU egisters setup. Since each BillingTOU energy register has a shadow maximum demand register, the number of sections in the file can be twice the number of the allocated BillingTOU registers. Sections within a file can be addressed by a section number, or by a section channel. A multi-section file has a single write position pointer for all sections and stores data in all sections simultaneously. This means that records with the same sequence number in all sections are associated with the same event. A multi-section file has also a single read position pointer for all sections. You can review the list of parameters recorded to the file through the file info requestresponse blocks using info requests with variation (see Section.8), or through the Data log #6 setup - it shows the list of parameters for the first file section, which represents the first configured energy usage register... File Transfers File transfer protocol provides both data transfer and information services. File transfer is performed through two blocks of registers: a -word master request block and a 68-word read-only file response block. After a master application has written the request into the file

12 request block, the requested data is available for a read through the file response block registers. File transfer functions allow changing the file or section position in order to point to the desired record. The information service uses separate 8-word file info request and -word file info response blocks. The extended file information is available including current file pointers positions, file contents, the number of records in the file, allocated file size, time of the last file update, and more. See Section.8 for information on register locations. Common File Transfer Log files can be read either in a sequence record-by-record, or in a random order. Each ead-file request fills the file response block with the data of the record pointed to by the file (or section) read pointer. If you want to begin reading a file from a particular record, which sequence number is known, you can change the pointer position by issuing the Set-File- Position request with the desired sequence number. If you want to read a file from the beginning, send the eset-file-position request that moves the pointer to the oldest file record. If you do not change the file position, then you will continue reading the file from the record following the one you have read the last time you accessed the file. You need not explicitly move the file position to the following record if you want to continue reading a file in sequence after you have uploaded the current record. Instead, issue an acknowledgment request that automatically advances the file pointer to the next record, and then read the record data through the file response block. The file response block can contain more than one record. The number of records available in the block and the file record size in words are always reported in the block heading. There are no special rules on how to read records from the file transfer block. You can read a single record or all records together, or begin reading from the last record and end with the first record. However, you should remember: ) after an acknowledgment, the file position moves to the record following the last one you have accessed in the file transfer block; and ) data in the file transfer block does not change until you either issue an acknowledgment, or explicitly change the file position by the Set-File-Position or eset-file-position requests. The file transfer is completed after you have read the last record of the file. Before storing a file record to your database, always check bit in the record status word, which contains the end-of-file (EOF) flag. This bit set to indicates that the file read pointer does not point to any record within the file, and you should not store any record that has this bit set. The EOF flag is set only after you have acknowledged the last record of the file, so that testing for end-of-file requires one extra read. If you wish to stop the transfer just after storing the last file record, acknowledge the record and check bit in the record status word. Bit is set to only once when you read the last record of the file. The following gives a summary of steps you should do to read an ordinal log file:. If you wish to begin reading a file from a particular record or from the first record, use either the Set-File-Position request with the desired record sequence number, or the eset-file-position request. Preset a section number and channel to zero.. rite the ead-file request with a section number and channel set to zero.. ead the record data from the file response block.. rite an acknowledgment for the file. You need not fill all the request fields: only the file function is required. The file pointer will be moved to the next file record.. epeat steps - until all the file records are read. eading Multi-section Profile Files In a multi-section data profile file, all user requests including an acknowledgment; the ead- File, Set-File-Position and eset-file-position requests, relate to a particular file section rather than to the file itself. A file section can be requested either by a section number, or by a section channel. If you use a channel, preset the section number field to xffff. If a section number is specified, the channel field will not be checked. The BFM66 returns both fields in the response block heading, so you can always identify what channel data is being read from the present

13 file section. If you want to know which channels are recorded to the file sections, check the file channel mask in the file info block. This is a bitmap that contains one in a bit position if a channel with an equal to the bit number is recorded to the file, and contains zero if it is not. The following gives a summary of steps for reading a multi-section data log file:. If you wish to begin reading a file section from a particular record or from the first record, use either the Set-File-Position request with the desired record sequence number, or the eset-file-position request. Specify either a section number, or the channel for the section from where you want to read data. If you use a channel, preset the section number field to xffff.. rite the ead-file request with the section number and channel as shown in the previous step.. ead the record data from the file response block.. rite an acknowledgment for the file. The file section pointer will be moved to the next record.. epeat steps - until all the section records are read.. TCP Notification Client The TCP notification client can establish connections with a remote ModbusTCP server and send notification messages either on events, or periodically on a time basis. Notification messages are sent via a block of 6 Modbus registers using write function 6. The following table shows the message exchange structure. Modbu s egist er Description Type Comment +- Device serial number UINT +- Device MAC address CHA 6 + Device address UINT Device IP address UINT +8 Event type UINT 6 + Event sequence number UINT 6 +- Event timestamp, seconds UINT +- Event timestamp, seconds fraction, in microseconds UINT +- eserved UINT Submeter address Network byte order See F in Section Local time since Jan, 7 ritten as After receiving a write acknowledgement from a server, a TCP connection is still open for seconds ( seconds via GPS) to give the server an opportunity to access meter registers through an open socket. It may help you access the meter from outside your local network when the server is located on another network, or when using wireless GPS communications. The notification client will respond to all server requests as if it were a regular incoming connection. If the server does not close a connection, it will be closed in seconds if there is no activity on the socket. In the event a connection attempt was unsuccessful, the notification client retries two more times before announcing a connection failure.

14 The server s IP address, port number and starting Modbus register address are programmable in the meter. See TCP Notification Client Setup for more information on the client setup. To configure and enable the notification client in your meter via PAS, select Communication Setup in the Meter Setup menu, and click on the TCP Notification Client Setup tab. Client connections are triggered via programmable setpoints. To send event notifications to a server, configure a setpoint to respond to desired triggers or to periodic time events and add the "Send notification" action to the end of the setpoint actions list.
