| In contrast with storage in the archive database, process values archived in the main memory are only available for as long as Runtime is active | |
| Storing in the main memory has the advantage, however, that the values can be written and read out very quickly. The process values stored in the main memory cannot be swapped out. | |
| Compressed archives cannot be saved in the main memory. |
You can swap out process values from the archive database as a backup. All process values contained in a data puffer are swapped out. The time of the swapping-out can be configured as you wish.
You configure process value swapping in Tag Logging in the shortcut menu of the "Archive" folder with the "Archive configuration" command. The swapping-out takes place separately for "Tag Logging Fast" and "Tag Logging Slow
On the "Archive Configuration" tab, configure the settings of the individual data buffers and specify what time period is to be contained in the archive. On the "Backup Configuration" tab, specify whether you want to create a backup of the archived process values and where the backup is to be stored.
In Runtime you can change a displayed process value with the OnlineTableControl. If the location of the archive segment where the process value is stored has already been changed, then the modified value is not accepted in the shifted archive. The change is limited to the local archive segment. If the archive segment has not yet been moved out, then the changed value is accepted permanently.
hive server The long-term archive server is used for backing up process value archives. Swap files can be accessed in three different ways: ● Copy swap files onto the configuration computer on which Runtime is run. Link the swap files to the project in the Alarm Logging or Tag Logging. The archived values are displayed in Runtime. ● Access via OLE-DB ● Access via DataMonitor Web Edition To set up a long-term archive server, run the WinCC "Fileserver Setup" on the computer. A minimum installation of WinCC is then installed on the computer. In order to be able to access the stored process value archive with ADO/OLE DB, the MS SQL server is also installed.
Significance of Archive Value Flags For each value written to the archive, Tag Logging will set a flag which provides information on the tag state. Representation of this flag is in the form of a 2-word value, coded in decimal form and listed in the 3rd column of the database archive. This flag must be converted to its hexadecimal representation for analysis purposes
