The properties described in this topic apply both to User Forms and User Pattern Forms. (User Patterns only apply to systems on which ClearSCADA can create new User accounts automatically as part of an External Authentication process. For more information, see Create User Accounts from a User Pattern.)
When a user accesses an Events List, the List only includes those events that have been logged during a specific time range. This time range can be adjusted on a per-user basis via the User Form (or, if applicable, via a User Pattern Form).
To specify the default time range for that user's Events List displays:
-
Either:
- Display the relevant User Form (to define the settings that apply to an individual User account).
- Display the relevant User Pattern Form (if applicable to your system, to define the settings that ClearSCADA is to apply to new User accounts that it might be triggered to create automatically at logon.)
- Select the General tab.
- Use the Event List Range fields to define the time range for the Events List. When the user that logs on via this account accesses an Events List, the Events List will initially include those events that were logged within the range defined in the Event List Range fields.
Enter the required offset in the OPC Relative Time Format. You can enter the value directly in the field, or use the Offset window (accessed via the field's browse button) to specify the required value. For example, enter H-24H to start the range at 24 hours prior to the start of the current hour.
