[Concept 3] Archive with Custom Storage Periods
Scenario
You want to create custom archive groups and associate data points with these groups.
1 – Create Custom Archive Groups
- System Manager is in Engineering mode.
- System Browser is in Management View.
- Custom Long Term Storage groups with monthly or yearly time slicing intervals are created in SMC.
NOTE: If a storage is full before the periods ends, the system automatically creates a new storage. In that case you will have more than one storage for that period.
- Select Project > Management System > Servers > Main Server > History Database > Archive Groups Custom.
- Click the Object Configurator tab.
- Click New and select New HDB Custom Archive Group.
- In the New object dialog box, enter the name and description.
- Click OK.
- In System Browser, select the newly created custom archive group.
- In the Operation tab, select the Archive property.
a. In the drop-down list, select the desired storage.
b. Click Set.
- Repeat steps 2 to 7 for all needed custom archive groups.
2 – Assigning Data Points to Archive Groups
- The custom archive groups are created and set to Archive.
- Perform either of the following:
- Select Project > Field Networks > [network] > Hardware > [device] > [data point]. The folder path may vary by view or subsystem.
- Select multiple objects for bulk engineering (See Bulk Engineering Objects).
- Click the Object Configurator tab.
- To assign datapoints to Activity and Events custom archive group, do the following:
a. In the Main expander, select the Archive group field.
b. In the drop-down list, select the desired archive group.
c. Click Save .
- To assign datapoints to Value custom archive group, do the following:
a. In the Properties expander, select the desired property, for example, Present Value.
b. Select the VL (data values, see Log Data Values in Logging Data Values or Events) check box or/and the AL (events, see Log Events in Logging Data Values or Events) check box.
c. Select the Archive group column.
d. In the drop-down list, select the desired archive group.
e. Click Save .
- Repeat steps 1 to 4 for all needed data points.
3 – Set the Retention Time for Default Archive Groups
- Define the retention period (refer Default: Deletion After Maximum Retention Period section) for all unassigned data points.
