| Analyze Archived Files on Startup | YES | KOM process, when starting, inspects old data sources in order to recalculate the value of electrical work. |
| Send Old Values | NO | Analyzes also the files that are older than "Maximum File Age". |
| Maximum File Age | 3 hod | If the interval is exceeded, the values are either ignored or processed as Old Values, depending on the parameter "Send Old Values". |

I/O tag address
...
I/O tag address consists of three parts. First one defines the value of work or performance. The second one - "Primary EAN Code" and "BackupEAN Code" are used as a unique identifier of value, which is placed in "Address Column Name" of source file. The third part represents the value type (AP+,AP-,AQ+,AQ-), which is in the "Value Type Column Name".

Error indication
...
The flags FA and FB are used to indicate the situations, when data processing was not done as expected. FB flag is set only for the performance values on condition that the files comes from other server, i.e. they are transmitted through FTP. It relates to the following situations:
...
In these cases, the values are archived without flag. The most recent valid value will have FB flag.
- There were received data with the same time stamp as current time stamp of I/O tag, but with the different value. FB flag is set for this particular value.
- The name of each processed file contains also the information about time. If this time is different from time stamp of value stored in the file, this data has also FB flag, in case of both archival and current value.
...
If the protocol is configured so that data are downloaded from FTP servers, user may set the primary and secondary FTP server. If data downloading from primary server failed, the secondary one is used. Data processed in such a way have FA flag.
These value flags are displayed in the archival dialog box of I/O tag, column "Value flag".
