IEC 62056-21:2002 File I/O
IEC62056-21:2002 File I/O communication protocol
Supported device types and versions
This protocol analyzes the files containing measurement data according to the IEC 62056 international standard.
Communication line configuration
Communication line category File I/O (communication via files).
File I/O communication line configuration parameters:
Input file - complete path to the file or directory with data.
In the case of analyzing a particular file, its size is tested with a 1-second period. If the file does not increase in size during two consecutive periods, it is processed.
If a directory is entered (in the case of a Win32 platform with a backslash (\) at the end), all files that match the mask are processed (see Station protocol parameters).
Archive directory -path to the directory, where the processed files are archived. If the directory is not specified, the processed files will be deleted.
Communication line protocol parameters
Dialog window communication line configuration - Protocol parameters tab, select the "IEC62056-21:2002 File I/O" protocol.
Table 1
Parameter | Description | Unit | Default value |
|---|---|---|---|
Profile | Analyzed profile. | - | P.01 |
Gorlitz PRM62 Module | Files from device Gorlitz PRM62 are analyzed. | YES/NO | NO |
Archive Subdirectory Time Mask | Mask for creating subdirectories in the main archive directory according to the time of file processing or timestamp of the file (if the Input file parameter specifies a directory). | - | rrrrmmdd |
Formatted Codes (Annex C) | Numerical addresses of I/O tags are used according to the specification of the IEC62056-21 standard, Annex C. | YES/NO | NO |
External Command File 1, 2 | The complete path to a periodically called external command file (.cmd). It is used only if a non-empty value has been configured. It is possible to configure two independently executed command files with different periods. | - | - |
External Command File Period 1,2 | Call period of the external command file 1 or 2. | mi:ss | 1:00 |
Call External Command File 1,2 Synchronously | Call external command files 1 or 2 synchronously. | YES/NO | YES |
Ext. Command File After Activation | The complete path to the external command file which is launched on change of redundancy status to HS. It is called only once and always synchronously. It is used only if a non-empty value has been configured. | - | - |
Debug Files Flow | Show debug information about processed files. | YES/NO | YES |
Debug Files Content | Show debug information with the content of processed files. | YES/NO | YES |
Debug Values | Show debug information with measured values of the measure points. | YES/NO | YES |
Files Checking Period | Period of input directory content check (if the Input file parameter specifies a directory). | mi:ss | 1:00 |
Unknown Files Backup Directory | File, where unknown files are saved (if the Input file is a directory). If it is not written, the files will be canceled. The unknown files are the files not-matching the configured mask (see Station protocol parameters) or the station with the required device number was not found. | - | - |
Future Data Filter | Time data filter. If the timestamp of acquired values is newer than the current time by more than the configured number of hours, they are ignored. Enter 0 (zero) to ignore the time filter. | hours | 24 |
History Data Filter | Time data filter. If the timestamp of acquired values is older than the current time by more than the configured number of hours, they are ignored. Enter 0 (zero) to ignore the time filter. | days | 31 |
Abnormal Timestamp Data Dir | Directory where the files with ignored data by time filter will be saved (Future Data Filter and History Data Filter). | - | - |
After Processing Timeout | A delay, which is inserted after the file was analyzed. | ss.mss | 0.100 |
Additional Error Logfile | Error file to write information about errors during processing (unknown file in directory, too old or too new values). An empty value means that this error file will not be created. | - | - |
Communication station configuration
Communication protocol "IEC62056-21:2002 File I/O".
Station address - the station address is ignored if the Input file is the particular file. If the directory is entered, the device number (electrometer) must be entered to assign the processed file to a particular station. If the station with this number does not exist, the file is considered to be unknown (see communication line protocol parameter Unknown files backup directory).
