This protocol analyzes the files containing data about measurement according to international standard IEC 62056.
Communication line configuration parameters File I/O:
In case of analyzing the particular file, its size is tested with a period 1 sec. If file does not increase during two consecutive periods, it is processed.
If directory is entered (in case of a platform Win32 with reverse solidus (\) at the end), all files that match the mask are processed (see station protocol parameters).
Dialog window communication line configuration - tab Protocol parameters, select the protocol "IEC62056-21:2002 File I/O".
Table 1
| Parameter | Description | Unit | Default value |
|---|---|---|---|
| Analyzed profile. | - | P.01 | |
| Gorlitz PRM62 Module | Files from device Gorlitz PRM62 are analyzed. | YES/NO | NO |
| Mask for generation of subdirectories in main archive directory according to time of file processing or time stamp of file (the Input file is the entered directory). | - | rrrrmmdd | |
| Numerical addresses of I/O tags are used according to specification of standard IEC62056-21, Annex C. | YES/NO | NO | |
| Complete path to periodically called external command file (.cmd). It is used only if non-empty value has been configured. It is possible to configure two independently executed command files with different periods. | - | - | |
| Call period of the external command file 1 or 2. | mi:ss | 1:00 | |
| Call external command file 1 or 2 synchronously. | YES/NO | YES | |
| Complete path to the external command file wich is launched at change of redundancy status to HS. It is called only once and always synchronously. It is used only if non-empty value has been configured. | - | - | |
| Show debug information about processed files. | YES/NO | YES | |
| Show debug information with the content of processed files. | YES/NO | YES | |
| Show debug information with measured values of the measure points. | YES/NO | YES | |
| Period of input directory content check (if the input file is a directory). | mi:ss | 1:00 | |
| File, where unknown files are saved (if the input file is directory). If it is not written, the files will be cancelled. The unknown files are the files inconvenient to mask (see station protocol parameters) or the station with required device number was not found. | - | - | |
| Time data filter. If the time stamp of acquired values is different from current time more than stated number of hours in future, they are ignored. Enter 0 (zero) to ignore time filter. | hours | 24 | |
| Time data filter. If the time stamp of acquired values is different from current time more than stated number of hours in past, they are ignored. Enter 0 (zero) to ignore time filter. | days | 31 | |
| Directory where the files with ignored data by time filter will be saved (Future Data Filter and History Data Filter). | - | - | |
| Timeout, it is inserted after the file was analyzed. | ss.mss | 0.100 | |
| Error file to write information about errors during processing (unknown file in directory, too old or too new values). Empty value means that this error file will not be created. | - | - |
Dialog window station configuration -
tab Protocol parameters.
They influence some optional protocol parameters. The following station protocol parameters can be entered:
Table 2
| Parameter | Description | Unit | Default value |
|---|---|---|---|
| If the input file is a particular file, after this timeout passes without a file being processed, then the station value is transferred to communication error. | min | 45 | |
| Mask for the name testing of the processed files. The following
digit placeholder can be used: {N} - electrometer number, beware of number of figure, e.g.{NNNNNNNN}, {yy} or {yyyy} - year, {mm} - month, {dd} - day, {hh} - hour, {mi} - minute, {ss} - second. Exmple of mask: "Meter_{NNNNNNNN}{yy}{mm}{dd}{hh}{mi}.abl". Time stamp gained from the file name (if it is possible) is used at file saving to archive directory (see communication line protocol parameters Archive subdirectory time mask). If the electrometer number is gained, it is used for searching the proper station. In case of not using the mask, the parameter should be empty. The station is, then, searched by acquired object value 0.0.0, C.1.0 or ZNR1 in case of Gorlitz PRM62. |
- | - | |
| Complete path to periodically called external command file (.cmd). The command file is called before accessing the input file. It is used only if non-empty value has been configured. | - | - | |
| Call period of the external command file. | mi:ss | 1:00 | |
| Call external command file synchronously. | YES/NO | YES |
Supported value types of I/O tags: Ai, Ci, TxtI.
Address of I/O tag corresponds to standard IEC 62056-61:2002 Object Identification system (OBIS), "Annex A - Code presentation".
Shortened address format is supported: C.D[.E][*F]
where is
A special I/O tag with address "$SW" acquires the value of profile status word.

where is:
P.01 - profile
(041022094500) - the time stamp of the first row with values
(00000000) - the profile status word
(15) - period of measurement in minutes
(4) - number of channels
(1.5) - first channel, 1 = Value Group C = Reactive power+, 5 = Value Group D = Last average 1
(MW) - unit of the first channel
etc.
Next rows contain the values of measurement.
