7 General This document specifies the SATEC ASCII serial communications protocol used to transfer data between a master computer station and the PM. The document provides the complete information necessary to develop third-party communications software capable of communication with the Series PM instruments. For additional information concerning operating the device, configuring the communication parameters, and communication connections see the PM PLUS Installation and Operation Manual. The document is applicable to PMA, PMP, PME and PMEH meters. IMPOTANT In -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 are provided. Most of the advanced features are configured using multiple setup parameters that can be accessed in a number of contiguous registers. hen 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. Designations used in the guide: E - available in the PME and PMEH EH - available in the PMEH

8 ASCII Protocol Description. ASCII Framing.. ASCII Message Frame The following specifies the ASCII message frame: Field No Contents SYN C Message length Slave addres Messag e type Message body Checksum Trailer (C LF) (!) s Length, char to 46 SYNC Synchronization character: one character '!' (ASCII ), used for starting synchronization. Message length The length of the message including only number of bytes in fields #, #, #4 and #5. Contains three characters between '6' and '5'. Slave address Contains two characters from '' to '99'. The instrument with address '' responds to requests with any incoming address. For S-4S-485 communications (multi-drop mode), this field must NEVE be zero. Message type Consists of one character representing the type of a host request. A list of the message types is shown in Tables - and -. Note that they are case-sensitive. Message body Contains the message parameters in ASCII representation. All parameter fields have a fixed format. The data fields vary in length depending on the data type. Unless otherwise indicated, the parameters should be right justified and left-padded with zeros. Most parameters are represented in ASCII hexadecimal notation, and in some cases (to provide compatibility with old devices) a decimal representation is preserved. For data formats, see Section.. Checksum Arithmetic sum, calculated in a -byte word over fields #, #, #4 and #5 to produce a onebyte check sum in the range of x to xe (hexadecimal) as follows: [ (each byte x)] mod x5c + x Trailer The message termination consisting of two ASCII characters C (ASCII ) and LF (ASCII ). NOTE Fields # and #4 of the instrument response are always the same as those in the host request. 8

Exception esponses The instrument will send the following error codes in the message body in response to incorrect host requests: XK - the meter is in programming mode XM - invalid request type or illegal operation XP - invalid data address or data value, or data is not available NOTE hen a check or framing error is detected, the meter will not act on or respond to the master's request.. Protocol Implementation.. ASCII Specific and Direct equests The ASCII protocol provides two different types of messages to transfer data between a master application and the meter: specific requests and direct readwrite requests. Specific ASCII requests use different formats for accessing different data locations. The message body differs depending on the request type. Each data field has a fixed position in the ASCII string. Section describes specific ASCII requests and their message body formats. Direct readwrite requests use a universal message body format, described in Section.4. These requests allow a master application to access different data locations (registers) in the instrument by specifying a direct register index. A number of consequent registers can be read or written by a single request by specifying an arbitrary start register and the number of registers to be accessed. Section 4 gives a register map for direct readwrite requests and their contents. All measurement data in your instrument can be accessed using direct read requests, and some data can be read via specific ASCII requests. In all cases, a direct register read offers you more precise data with extended resolution. Setup data can be partially accessed using both specific and direct requests, and partially via either specific or direct requests. 9

10 .. Data Formats Specific ASCII requests use both decimal and hexadecimal notation. Direct requests transfer ASCII data only in a hexadecimal format. Using a decimal notation, data is transmitted in a decimal representation as is, i.e., no conversion is needed. Negative numbers are transmitted with a sign at the left. Fractional numbers are represented with a decimal point. hen the value exceeds the field width, it is truncated to the right. In a hexadecimal notation, each data byte is transferred by two hexadecimal characters in ASCII representation (i.e., ASCII printable characters -9, A-F are used to represent hexadecimal digits x-x9, xa-xf). All data is transferred as -character (8-bit unsigned byte), 4-character (6-bit unsigned or signed integer) or 8-character (-bit unsigned or signed long integer) whole numbers. Negative numbers are transmitted in - complement code. Each data byte is transmitted high order digit first. Each integer or long integer register is transmitted high order bytes first. Fractional numbers are transmitted being scaled by in power N, where N is the number of digits in the fractional part. For example, the frequency reading of 5. Hz is transmitted as 5 being pre-multiplied by. henever a data register contains a fractional number, the register measurement unit is given with a multiplier.,. or., 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 Direct eadrite equest.4. General In direct readwrite requests, data registers are addressed by point ID s that are given in a 4-digit hexadecimal format. All data is transmitted in ASCII hexadecimal notation as -character (UINT8, 8-bit unsigned byte), 4-character (6-bit unsigned UINT6 or signed INT6 integer) or 8-character (-bit unsigned or signed INT long integer) numbers. Negative numbers are transmitted in -complement code. egister type in the tables below shows an actual data size for data accessed using variable-size direct readwrite requests. hen long-size direct readwrite request is used, an actual data size is ignored and all registers are transmitted in an 8-character format as long signed (INT) or unsigned () integers..4. Long-Size Direct eadrite In long-size direct readwrite messages, all data items are read and written as long unsigned () or signed (INT) integers, which are represented in messages by 8-digit hexadecimal numbers, regardless of the actual data size. Up to contiguous points can be read in one message once. A write request allows for writing only one data location at a time.

Points that reside in different locations may be accessed by a single request by re-mapping them to adjacent points in the user assignable registers area.

12 The actual point ID s of the assignable registers, which are accessed via addresses x8 through x8, are specified in the register map through points x8-x8, where point x8 contains the actual point ID of the register accessed via point x8, point x8 contains the actual point ID of the register accessed via point x8, 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 (points x8-x8) the actual point ID s of the registers you want to read from or write to via the assignable points x8-x8. For example, if you want to read points xc (real-time voltage of phase A) and x (kh import) through points x8-x8, do the following: - write xc to point x8 - write x to point x8 eading from points x8-x8 will return the voltage reading through point x8, and the kh reading through point x8..5 Password Protection The PM 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 via the front display. For details, refer to your instrument Installation and Operation Manual. hen password protection is enabled, the user password you set in your instrument should be written into the device authorization register (point xff) 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 XM (illegal operation). It is recommended to clear the password register after you have completed your changes in order to activate password protection..6 Data ecording and File Transfers.6. Log File Organization Historical files are stored to the non-volatile memory. Memory is allocated for each file statically when you set up your files and will not change unless you re-organize the files. The PM automatically performs de-fragmentation of the memory each time you re-organize your files. This helps keep all free memory in one continuous chunk and thus prevents possible leakage of memory caused by fragmentation. 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 6556 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. If a file has a wrap-around attribute (circular file), the most recent records can overwrite 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 PM 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.

13 Multi-tion Files Log files can have one or more (up to 8) tions for multi-channel recording. An ordinal file consists of a single tion. A daily profile log file is arranged as a multi-tion file. A multi-tion file is subdivided into multiple tions of the same structure, one tion per recording channel. The number of tions in each file is defined at the time you set up your files and may not change unless you re-organize the file. Each tion within a multi-tion file can be addressed through a particular register window related to the tion. A multi-tion file has a single write position pointer for all tions and stores data in all tions simultaneously. This means that records with the same sequence number in all tions are associated with the same event. A multi-tion file has also a single read position pointer for all tions. Data Log Files Data log files can store up to 9 measured parameters per a record. Any data measured by the device can be stored in the log file. 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 files can be triggered through the setpoints, either on a time basis using the meter clock or periodic timers, or upon any event detected by setpoints. Profile Data Log File Data log file #6 can be configured for a daily profile log of the energy usage and maximum demand registers. A profile log file is organized as a multi-tion file that has a separate tion 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 SummaryTOU register. See Section 4.8 for information on the file record structure. The number of tions is taken automatically from the SummaryTOU egisters setup. Since each SummaryTOU energy register has a shadow maximum demand register, the number of tions in the file can be twice the number of the allocated SummaryTOU registers. Always configure the SummaryTOU registers before you allocate memory for your profile log file. New records are added to the file automatically every day at midnight. You can review the list of parameters that are recorded to the file through the Data log #6 setup. It is preset automatically by the meter and shows the recorded data for the first file tion, which represents the first configured energy usage register. eal-time aveforms eal-time waveforms are read as a multi-tion file that stores data for each recording channel in a separate tion. A real-time waveform contains six AC channels - three voltage and three current waveforms, which are recorded in successive tions. A single waveform record for a channel contains 5 points of the sampled input signal. efer to the line frequency field in the channel header record to correctly set up the time scale for the waveforms..6. File Transfers File transfer protocol provides both data transfer and information services. File transfer is performed through blocks of registers separate for each file and file tion. File transfer control registers allow changing the file or tion position in order to point to the desired record. The information service uses separate statuscontrol registers for each file. The extended file information is available including current file pointers positions, the number of records in the file, allocated file size, and more. See Section 4. File Transfer egisters for information on register locations.

14 Common File Transfer Log files can be read either in a sequence record-by-record, or in a random order. Each read request fills the corresponding register block with the data of the record pointed to by the file (or tion) 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 writing the desired sequence number into the file transfer control register. If you want to read a file from the beginning, you can simply write a corresponding command to the file command register 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 a sequence after you have uploaded the current record. Instead, continue reading the file through the file transfer block. For the event log files, the file transfer block can contain up to 6 records that can be read at once: the file position automatically moves to the record following the last one you have just read in the file transfer block. 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 read 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, 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 want to begin reading a file from a particular record or from the first record, either set the file position to the desired record sequence number, or preset the file position to point to oldest record.. ead the record data through the corresponding file transfer block. The file pointer will be automatically moved to the next file record.. epeat steps - until all the file records are read, i.e., until either bit or bit is set in the record status word. eading a Daily Profile Log File eading a multi-tion profile log file does not differ from reading ordinal files with the only exception that each file tion is accessed through a separate transfer block. If you want to know which registers are recorded to the file tions before reading them, check the daily profile log tions map through point xaf4 (see Section 4., File Transfer egisters). This is a bitmap that contains one in a bit position if a designated register is recorded to the file, and contains zero if it is not. The following gives a summary of steps for a multi-tion file:. If you want to begin reading a file tion from a particular record or from the first record, either set the file tion position to the desired record sequence number, or preset the file tion position to point to oldest record.. ead the record data through the corresponding file tion transfer block. The file pointer automatically moves to the next file record.. epeat steps - until all the file tion records are read, i.e., until either bit or bit is set in the record status word. eading eal-time aveforms Each waveform record consists of six channel records that are read in sequence always starting with channel V. Each channel s data is read in two stages. The channel header record is read first through a separate transfer block followed be reading the channel sample series. Each time you read the V channel header record, the meter captures new waveforms 4

15 to the buffer so that you can then read all of them through the waveform transfer blocks. The following gives a summary of steps for reading real-time waveforms:. ead the V channel header data through the corresponding real-time waveform header transfer block. The captured waveform s data is moved to the port s communication buffer.. ead the V channel sample series through the waveform series transfer block.. ead the next channel s header data through the corresponding waveform header transfer block. 4. ead the sample series for the selected channel through the waveform series transfer block. 5. epeat steps, 4 until all channels records are read. 5

Total harmonics are only available in PMEH meters. Voltage and voltage harmonics readings: when the 4LN, LN or BLN wiring mode is selected, the voltages will be line-to-neutral; for any other wiring mode, they will be line-to-line voltages. All analog registers except of harmonics are -ond average values. For volts, amps and power scales and units, refer to Section 5 Data Scales and Units. hen ASCII compatibility mode is disabled (see Section 5.5), voltages, currents and powers are transmitted with a decimal point in units defined in the table. hen the value is greater than the field width, the right most digits of the fractional part are truncated. hen ASCII compatibility mode is enabled, the meter provides a fully downward-compatible response using a lower resolution for voltages, currents and powers - the value is transmitted as a whole number until the field is filled up, and then it is converted to higher units and transmitted with a decimal point. If the value is greater than the field width, the right most digits of the fractional part are truncated. Voltages are transmitted in volts as whole numbers or in kilovolts with a decimal point, currents in amperes as whole numbers, and powers in kilowatts as whole numbers or in megawatts with a decimal point. Energy readings are transmitted in Mh, Mvarh and MVAh units with a decimal point. If the energy value exceeds the field width, the right-most digits are truncated. If you use these request for energy readings, then, to avoid overflow, limit the energy roll value (see Device Options Setup) to digits if you use kvarh net reading or to 8 digits if you do not use it. 4 For negative power factor, the minus sign is transmitted before a decimal point as shown in the table. 5 In LL wiring mode the Harmonics calculations are not supported.
